    1993-12-31

    The purpose of this paper is to provide an accurate overview of the development and structure of the program established by the Health Physics Society (HPS) for accrediting instrument calibration laboratories relative to their ability to accurately calibrate portable health physics instrumentation. The purpose of the program is to provide radiation protection professionals more meaningful direct and indirect access to the National Institute of Standards and Technology (NIST) national standards, thus introducing a means for improving the uniformity, accuracy, and quality of ionizing radiation field measurements. The process is designed to recognize and document the continuing capability of each accredited laboratory to accurately perform instrument calibration. There is no intent to monitor the laboratory to the extent that each calibration can be guaranteed by the program; this responsibility rests solely with the accredited laboratory.

  4. High-dose secondary calibration laboratory accreditation program

    International Nuclear Information System (INIS)

    There is a need for high-dose secondary calibration laboratories to serve the multi-billion dollar radiation processing industry. This need is driven by the desires of industry for less costly calibrations and faster calibration-cycle response time. Services needed include calibration irradiations of routine processing dosimeters and the supply of reference standard transfer dosimeters for irradiation in the production processing facility. In order to provide measurement quality assurance and to demonstrate consistency with national standards, the high-dose secondary laboratories would be accredited by means of an expansion of an existing National Voluntary Laboratory Accreditation Program. A laboratory performance criteria document is under development to implement the new program

  7. The DOE Laboratory Accreditation Program performance testing laboratory automated calibration verification program

    International Nuclear Information System (INIS)

    The Performance Testing Laboratory for the DOE Laboratory Accreditation Program (DOELAP) resides at the Radiological and Environmental Sciences Laboratory (RESL) on the Idaho National Engineering Laboratory (INEL). A system has been developed to verify the calibration of Cesium 137 irradiators using a reference class ionization chamber under computer control. The measurement system consists of irradiators, a Victoreen Model 415 ionization chamber, a Keithley Model 617 electrometer, a high voltage power supply, a VAXLAB microVAX II processor controller, a Fluke digital thermometer, a Heise digital barometer and an Optomux interface between the computer and irradiator. The ionization chamber is placed in an irradiation fixture which is affixed to the dosimeter phantom stand. The computer then executes a variety of steps to conduct the irradiation and measurement. The data taken over the last six months indicate that all of the irradiator geometries meet requirements in the governing standards

  8. History, organization, and oversight of the accredited dosimetry calibration laboratories by the AAPM

    International Nuclear Information System (INIS)

    For more than 20 years, the American Association of Physicists in Medicine (AAPM) has operated an accreditation program for secondary standards laboratories that calibrate radiation measuring instruments. Except for one short period, that program has been able to provide the facilities to satisfy the national need for accurate calibrations of such instruments. That exception, in 1981, due to the combination of the U.S. Nuclear Regulatory Commission (NRC) requiring instrument calibrations by users of cobalt-60 teletherapy units and the withdrawal of one of the three laboratories accredited at that time. However, after successful operation as a Task Group of the Radiation Therapy Committee (RTC) of the AAPM for two decades, a reorganization of this structure is now under serious consideration by the administration of the AAPM

  10. QA experience at the University of Wisconsin accredited dosimetry calibration laboratory

    International Nuclear Information System (INIS)

    The University of Wisconsin Accredited Dosimetry Calibration Laboratory (UW ADCL) employs procedure manuals as part of its Quality Assurance (QA) program. One of these manuals covers the QA procedures and results for all of the UW ADCL measurement equipment. The QA procedures are divided into two main areas: QA for laboratory equipment and QA for external chambers sent for calibration. All internal laboratory equipment is checked and recalibrated on an annual basis, after establishing its consistency on a 6-month basis. QA for external instruments involves checking past calibration history as well as comparing to a range of calibration values for specific instrument models. Generally, the authors find that a chamber will have a variation of less than 0.5 % from previous Co-60 calibration factors, and falls within two standard deviations of previous calibrations. If x-ray calibrations are also performed, the energy response of the chamber is plotted and compared to previous instruments of the same model. These procedures give the authors confidence in the transfer of calibration values from National Institute of Standards and Technology (NIST)

  16. Laboratory accreditation in developing economies

    International Nuclear Information System (INIS)

    Full text: Accreditation of laboratories has been practiced for well over one hundred years with the primary objective of seeking a formal recognition for the competence of a laboratory to perform specified tests or measurements. While first accreditation schemes intended initially to serve only the immediate needs of the body making the evaluation with the purpose of minimizing testing and inspection to be conducted by laboratories, third-party accreditation enables a laboratory to demonstrate its capability as well as availability of all necessary resources to undertake particular tests correctly and that is managed in such a way that it is likely to do this consistently, taking into consideration standards developed by national and international standards-setting bodies. The international standard ISO/IEC 17025 and laboratory accreditation are concerned with competence and quality management of laboratories only, thus requiring a single common set of criteria applicable to them. Quality assurance is therefore fully relevant to laboratories in general and analytical laboratories in particular; it should not be confused with the certification approach according to ISO/IEC 9000 family of standards, that is concerned with quality management applicable to any organization as a whole. The role of laboratory accreditation can be manifold, but in all cases the recipient of the test report needs to have confidence that the data in it is reliable, particularly if the test data is important in a decision-making process. As such, it offers a comprehensive way to ensure: - the availability of managerial and technical staff with the authority and resources needed; - the effectiveness of equipment management, traceability of measurement and safety procedures; - the performance of tests, taking into consideration laboratory accommodation and facilities as well as laboratory practices. The presentation will include also some practical aspects of quality management system

  18. Accreditation of laboratories in the field of radiation protection

    International Nuclear Information System (INIS)

    This paper gives a review of requirements and procedures for the accreditation of test and calibration laboratories in the field of radiation protection, paying particular attention to Croatia. General requirements to be met by a testing or calibration laboratory to be accredited are described in the standard HRN EN ISO/IEC 17025, General requirements for the competence of testing and calibration laboratories. The quality of a radiation protection programme can only be as good as the quality of the measurements made to support it. Measurement quality can be assured by participation in measurement assurance programmes that evaluate the appropriateness of procedures, facilities, and equipment and include periodic checks to assure adequate performance. These also include internal consistency checks, proficiency tests, intercomparisons and site visits by technical experts to review operations. In Croatia, laboratories are yet to be accredited in the field of radiation protection. However, harmonisation of technical legislation with the EU legal system will require some changes in laws and regulations in the field of radiation protection, including the ones dealing with the notification of testing laboratories and connected procedures. Regarding the notification procedures for testing laboratories in Croatia, in the regulated area, the existing accreditation infrastructure, i.e. Croatian Accreditation Agency is ready for its implementation, as it has already established and further developed a consistent accreditation system, compatible with international requirements and procedures.(author)

    Accreditation is an internationally recognised way for laboratories to demonstrate their competence. Obtaining and maintaining accreditation is, however, a costly and time-consuming procedure. The benefits of accreditation also depend on the role of the laboratory. Accreditation may be of limited relevance for a research laboratory, but essential for a laboratory associated with a national authority and e.g. issuing certificates. This report describes work done within the NKSBOK-1.1 sub-project on introducing accreditation to Nordic laboratories measuring radionuclides. Initially the focus was on the new standard ISO/IEC 17025, which was just in a draft form at the time, but which provides now a new framework for accreditation of laboratories. Later the focus was widened to include a general introduction to accreditation and providing through seminars a forum for exchanging views on the experience laboratories have had in this field. Copies of overheads from the last such seminar are included in the appendix to this report. (au)

  1. Accreditation in university environmental radioactivity laboratories

    International Nuclear Information System (INIS)

    Full text: The experimental work performed in university laboratories comes from many different fields and it is assumed to be of high quality. In general, the results are published in national or international journals or presented at conferences. Only a few laboratories have a clear understanding of the importance of implementing Quality Assurance Systems and the accreditation of their activities according to the international standards, such as ISO 17025. Today, few universities include this issue in the ir programmes. Most laboratories associate quality assurance with the fact that referees before publication have revised their works. Here the authors describe their experience in two university laboratories involved in environmental radioactivity control. Both laboratories have implanted a Quality Assurance System based on ISO 17025, the standard used for accreditation of the technical competence of laboratories. One of them (LARA-UPC) belongs to a research institute and the other (LRAUB) belongs to a university department with different logistic organisation. Both laboratories provide services to public and private institutions along side their teaching and research activities. The Quality Assurance Unit (UGQ-UB) is responsible for activities related to technical support in implementation and assessment in quality systems. In the case of these laboratories this UGQ performs internal audits. Accreditation is particularly important in environmental radioactivity analysis, where objective evidence of the quality of the data is required. Moreover, the results of radioactivity analysis are important: e.g. quality of water for human consumption (Directive 98/83/CE), environmental surveys (PVRA, Art. 35 of the Euratom Treaty for EU members), imports of agricultural products (Directive 99/1661/EC), export certificate required for agricultural products (2001/1621/EC), measurements in support of health and safety.

  14. Accreditation of testing laboratories in CNEA (National Atomic Energy Commission)

    International Nuclear Information System (INIS)

    The recognition of the technical capability of a testing laboratory is carried out by Laboratory Accreditation Bodies as the result of a satisfactory evaluation and the systematic follow up of the certified qualification. In Argentina the creation of a National Center for the Accreditation of Testing Laboratories, as a first step to assess a National Accreditation System is currently projected. CNEA, as an institution involved in technological projects and in the development and production of goods and services, has adopted since a long time ago quality assurance criteria. One of their requirements is the qualification of laboratories. Due to the lack of a national system, a Committee for the Qualification of Laboratories was created jointly by the Research and Development and Nuclear Fuel Cycle Areas with the responsibility of planning and management of the system evaluation and the certification of the quality of laboratories. The experience in the above mentioned topics is described in this paper. (author)

  18. Accreditation to ISO 17025:2005 for the Radioactivity Metrology Group of the UK's National Physical Laboratory

    International Nuclear Information System (INIS)

    In the mid 1990s, the National Physical Laboratory (NPL) took the decision to seek external accreditation to the then UK national accreditation standard (M10, M10 supplement and M11) through the NPL's National Measurement Accreditation Service (NAMAS). This paper details the reasoning behind that initial decision and, in particular, how this impinged on the day-to-day activities of the NPL's Radioactivity Metrology Group (RMG). In the intervening decade, the accreditation standard has changed considerably; accreditation is now to the international standards ISO 9001:2000 (Quality Management Systems: Requirements) and ISO 17025:2005 (General Requirements for the Competence of Testing and Calibration Laboratories); accreditation is now carried out by a wholly separate successor organization to NAMAS, the United Kingdom Accreditation Service (UKAS). To meet the new accreditation requirements the RMG: realigned it's scope of work; streamlined and consolidated written procedures, references and appendices; centralized the collection of written procedures, and clarified the document identification system. Future developments will include efforts for RMG accreditation for conducting proficiency tests and providing reference materials. (author)

    Full Text Available This review attempts to clarify the concepts of Laboratory Quality Management System (Lab QMS for a medical testing and diagnostic laboratory in a holistic way and hopes to expand the horizon beyond quality control (QC and quality assurance. It provides an insight on accreditation bodies and highlights a glimpse of existing laboratory practices but essentially it takes the reader through the journey of accreditation and during the course of reading and understanding this document, prepares the laboratory for the same. Some of the areas which have not been highlighted previously include: requirement for accreditation consultants, laboratory infrastructure and scope, applying for accreditation, document preparation. This section is well supported with practical illustrations and necessary tables and exhaustive details like preparation of a standard operating procedure and a quality manual. Concept of training and privileging of staff has been clarified and a few of the QC exercises have been dealt with in a novel way. Finally, a practical advice for facing an actual third party assessment and caution needed to prevent post-assessment pitfalls has been dealt with.

    One important trend in the laboratory profession and quality management is the global convergence of laboratory operations. The goal of an accredited medical laboratory is to continue "offering useful laboratory service for diagnosis and treatment of the patients and also aid to the health of the nation". An accredited clinical laboratory is managed by a quality control system, it is competent technically and the laboratory service meets the needs of all its patients and physicians by taking the responsibility of all the medical tests and therapies. For this purpose, ISO 15189 international standard has been prepared by 2003. ISO 15189 standard is originated from the arrangement of ISO 17025 and ISO 9001:2000 standards. Many countries such as England, Germany, France, Canada and Australia have preferred ISO 15189 as their own laboratory accreditation programme, meeting all the requirements of their medical laboratories. The accreditation performance of a clinical microbiology laboratory is mainly based on five essential points; preanalytical, analytical, postanalytical, quality control programmes (internal, external, interlaboratory) and audits (internal, external). In this review article, general concepts on ISO 15189 accreditation standards for the clinical microbiology laboratories have been summarized and the status of a private laboratory (Acibadem LabMed, Istanbul) in Turkey has been discussed.

    Full Text Available Introduction: The Lesotho Ministry of Health and Social Welfare’s (MOHSW 5-year strategic plan, as well as their national laboratory policy and yearly operational plans, directly addresses issues of accreditation, indicating their commitment to fulfilling their mandate. As such, the MOHSW adopted the World Health Organization Regional Headquarters for Africa’s Stepwise Laboratory Quality Improvement Toward Accreditation (WHO–AFRO–SLIPTA process and subsequently rolled out the Strengthening Laboratory Management Towards Accreditation (SLMTA programme across the whole country, becoming the first African country to do so. Methods: SLMTA in Lesotho was implemented in two cohorts. Twelve and nineteen laboratory supervisors and quality officers were enrolled in Cohort 1 and Cohort 2, respectively. These 31 participants represented 18 of the 19 laboratories nationwide. For the purposes of this programme, the Queen Elizabeth II (QE II Central Laboratory had its seven sections of haematology, blood bank, cytology, blood transfusion, microbiology, tuberculosis laboratory and chemistry assessed as separate sections. Performance was tracked using the WHO–AFRO-SLIPTA checklist, with assessments carried out at baseline and at the end of SLMTA. Two methods were used to implement SLMTA: the traditional ‘three workshops’ approach and twinning SLMTA with mentorship. The latter, with intensive follow-up visits, was concluded in 9 months and the former in 11 months. A standard data collection tool was used for site visits.Results: Of the 31 participants across both cohorts, 25 (81% graduated (9 from Cohort 1 and 16 from Cohort 2. At baseline, all but one laboratory attained a rating of zero stars, with the exception attaining one star. At the final assessment, 7 of the 25 laboratories examined at baseline were still at a rating of zero stars, whilst 8 attained one star, 5 attained two stars and 4 attained three stars. None scored above three stars

    The X-ray Calibration Laboratory (XCL) of the Center for Devices and Radiological Health (CDRH) provides calibration services for the Food and Drug Administration (FDA). The instruments calibrated are used by FDA and contract state inspectors to verify compliance with federal x-ray performance standards and for national surveys of x-ray trends. In order to provide traceability of measurements, the CDRH XCL is accredited by the National Voluntary Laboratory Accreditation Program (NVLAP) for reference, diagnostic, and x-ray survey instrument calibrations. In addition to these accredited services, the CDRH XCL also calibrates non-invasive kVp meters in single- and three-phase x-ray beams, and thermoluminescent dosimeter (TLD) chips used to measure CT beam profiles. The poster illustrates these services and shows the traceability links back to the National Standards.

  10. Analysis of ISO/IEC 17025 for establishment of KOLAS (Korea Laboratory Accreditation Scheme) quality assurance system

    International Nuclear Information System (INIS)

    Besides one existent accredited lab, radioactive material chemical analysis lab, five test laboratories and two calibration labs are under plan to acquire the accreditation from KOLAS. But the current Quality Manual was developed according to ISO Guide 25 that was superceded by ISO/IEC 17025. Since it is tailored to the radioactive material chemical analysis lab, a number of requirements of the Manual are not applicable to the labs other than radioactive material chemical analysis lab. Through the analysis of ISO/IEC 17025, a model of quality system was established which is not only consistent with ISO/IEC 17025 but reflective of the KAERI's situation

  11. Sense and nonsense in the process of accreditation of a pathology laboratory.

    Science.gov (United States)

    Long-Mira, Elodie; Washetine, Kevin; Hofman, Paul

    2016-01-01

    The aim of accreditation of a pathology laboratory is to control and optimize, in a permanent manner, good professional practice in clinical and molecular pathology, as defined by internationally established standards. Accreditation of a pathology laboratory is a key element in fine in increasing recognition of the quality of the analyses performed by a laboratory and in improving the care it provides to patients. One of the accreditation standards applied to clinical chemistry and pathology laboratories in the European Union is the ISO 15189 norm. Continued functioning of a pathology laboratory might in time be determined by whether or not it has succeeded the accreditation process. Necessary requirements for accreditation, according to the ISO 15189 norm, include an operational quality management system and continuous control of the methods used for diagnostic purposes. Given these goals, one would expect that all pathologists would agree on the positive effects of accreditation. Yet, some of the requirements stipulated in the accreditation standards, coming from the bodies that accredit pathology laboratories, and certain normative issues are perceived as arduous and sometimes not adapted to or even useless in daily pathology practice. The aim of this review is to elaborate why it is necessary to obtain accreditation but also why certain requirements for accreditation might be experienced as inappropriate. PMID:26334197

  12. Development of a quality assurance program for ionizing radiation secondary calibration laboratories

    International Nuclear Information System (INIS)

    For calibration laboratories, routine calibrations of instruments meeting stated accuracy goals are important. One method of achieving the accuracy goals is to establish and follow a quality assurance program designed to monitor all aspects of the calibration program and to provide the appropriate feedback mechanism if adjustments are needed. In the United States there are a number of organizations with laboratory accreditation programs. All existing accreditation programs require that the laboratory implement a quality assurance program with essentially the same elements in all of these programs. Collectively, these elements have been designated as a Measurement Quality Assurance (MQA) program. This paper will briefly discuss the interrelationship of the elements of an MQA program. Using the Center for Devices and Radiological Health (CDRH) X-ray Calibration Laboratory (XCL) as an example, it will focus on setting up a quality control program for the equipment in a Secondary Calibration Laboratory

    Full Text Available It’s introduced Lean techniques in a Clinical Laboratory to improve the operability and the efficiency in continuous processes of analysis, failsafe systems, analysis of areas of value pursuit of zero defects and reduction of waste, and it promote continuous improvement in presented difficulties in adapting to the changing needs of the healthcare environment. Whereas it is necessary to incorporate certification and accreditation, note that the adaptability of the clinical laboratory to the changing needs of physicians in obtaining analytical information is reduced. The application of an agile methodology on analytical systems can provide a line of work that allows the incorporation of planning short work cycles on equips quickly with operational autonomy on the basis of demand and respecting the accreditation requirements and flexibility to ensure adequate performance as the intercomparison of results from the different units analytics, analytical quality and turnaround times. Between 2012 and 2014, a process of analysis and improvement was applied to circuits, a 5 s system, transportation of samples, inventory of reactive and samples, motion of personal and samples, reductions of waiting and delays, overproduction, over processing, and defects of results and reports. At last it seems necessary to apply the Agile methodology to adapt to the evolving necessities in time and the different origins of the samples. It’s have used modular systems where the modules of this study are programmed with immunoassay techniques and it has reduced the operative modules depending on the required activity, ensuring the goals of turnaround times, analytic quality, service, health care continuity, and keeping up with the ISO 15189 accreditation requirements. The results of applying the concept of Lean-Agile to a modular system allows us to reduce the associated costs to the seasonal variation of the health care demand and to adapt the system to the changes on

  15. The Belgian laboratory for standard dosimetry calibrations used in radiotherapy

    International Nuclear Information System (INIS)

    Starting from the end of the year 2008, the RDC (Radiation Protection dosimetry and Calibrations) expertise group of SCK CEN took over the calibration and research activities at the Laboratory for Standard Dosimetry Ghent. The laboratory runs under a collaboration between SCK CEN and the University of Ghent, with the support of Federal Agency for Nuclear Control (FANC). The calibrations in Ghent were stopped at the beginning of 2008 and then restarted at the end of 2008. A new 60Co source was installed at Ghent, a Theratron 780 unit. All the calibration setups installed in the past to the old 60Co source had to move to the new source and measurement history had to be acquired. The calibration of cylindrical and plane-parallel ionization chambers in terms of absorbed dose to water was defined as the first priority, since there was an urgent need from the Belgian hospitals. These calibrations are presently done in Ghent as secondary standard calibrations, traceable to the water calorimeter of VSL, Delft, The Netherlands and following the recommendations from TRS-398 protocol. The second priority was restarting the calibrations of cylindrical ionization chambers in terms of air kerma. A cylindrical graphite ionization chamber of type CC01 is used for the absolute measurement of air kerma. Both setups are fully operational. Special efforts were done to implement the SCK CEN quality assurance (QA) system regarding ISO 17025 accreditation. The activity at the laboratory in Ghent was integrated as part of the Laboratory for Nuclear Calibrations (LNK-from the Dutch translation) of the SCK-CEN. Most of the activities of the LNK are already accredited by Belgian Accreditation Body (BELAC) with respect to the ISO-17025 standards. The quality assurance procedures were prepared and are routinely followed for the two new setups mentioned above: calibrations in terms of absorbed dose to water and air kerma in 60Co beam. During the preparation of the quality assurance procedures

  17. Implementation of ISO guide 25 in a medical dosimetry secondary standards calibration laboratory

    International Nuclear Information System (INIS)

    Currently, there is a great deal of discussion among industry and government agencies about ISO 9000 accreditation. U.S. manufacturers with ISO 9000 accreditation are regarded more favorably by European countries. The principles behind the ISO 9000 accreditation are based on the Total Quality Management (TQM) principles that are being implemented in many U.S. industries. This paper will deal only with the calibration issue. There is a difference in the areas covered by ISO 9000 and ISO Guide 25 documents. ISO 9000, in particular ISO 9001 - ISO 9003, cover the open-quotes calibrationclose quotes of inspection, measuring and test equipment. This equipment is basically used for open-quotes factory calibrationsclose quotes to determine that equipment is performing within manufacturer specifications. ISO Guide 25 is specifically for open-quotes calibration and testing laboratories,close quotes generally laboratories that have painstaking procedures to reduce uncertainties and establish high accuracy of the transfer of calibration. The experience of the University of Wisconsin Accredited Dosimetry Calibration Laboratory in conforming to ISO Guide 25 will be outlined. The entire laboratory staff must become familiar with the process and an individual with direct authority must become the one to maintain the quality of equipment and calibrations in the role of open-quotes quality-assurance manager.close quotes

    1993-12-31

    Accreditation of personnel dosimetry systems is required for laboratories that conduct personnel dosimetry for the U.S. Department of Energy (DOE). Accreditation is a two-step process which requires the participant to pass a proficiency test and an onsite assessment. The DOE Laboratory Accreditation Program (DOELAP) is a measurement quality assurance program for DOE laboratories. Currently, the DOELAP addresses only dosimetry systems used to assess the whole body dose to personnel. A pilot extremity DOELAP has been completed and routine testing is expected to begin in January 1994. It is expected that participation in the extremity program will be a regulatory requirement by January 1996.

    Full Text Available Background: The National HIV Reference Laboratory (NHRL serves as Kenya’s referral HIV laboratory, offering specialised testing and external quality assessment, as well as operating the national HIV serology proficiency scheme. In 2010, the Kenya Ministry of Health established a goal for NHRL to achieve international accreditation.Objectives: This study chronicles the journey that NHRL took in pursuit of accreditation, along with the challenges and lessons learned.Methods: NHRL participated in the Strengthening Laboratory Management Toward Accreditation (SLMTA programme from 2010–2011. Improvement projects were undertaken to address gaps in the 12 quality system essentials through development of work plans, team formation, training and mentorship of personnel. Audits were conducted and the scores used to track progress along a five-star grading scale. Standard quality indicators (turn-around time, specimen rejection rates and service interruptions were measured. Costs of improvement projects and accreditation were estimated based on expenditures.Results: NHRL scored 45% (zero stars at baseline in March 2010 and 95% (five stars after programme completion in October 2011; in 2013 it became the first public health laboratory in Kenya to attain ISO 15189 accreditation. From 2010–2013, turn-around times decreased by 50% – 95%, specimen rejections decreased by 93% and service interruptions dropped from 15 to zero days. Laboratory expenditures associated with achieving accreditation were approximately US $36 500.Conclusion: International accreditation is achievable through SLMTA, even for a laboratory with limited initial quality management systems. Key success factors were dedication to a shared goal, leadership commitment, team formation and effective mentorship. Countries wishing to achieve accreditation must ensure adequate funding and support.

  20. Accreditation of nondestructive testing (NDT) laboratories: do we have choices?

    International Nuclear Information System (INIS)

    Demand for quality of products and services by consumers throughout the world resulted in fierce competition among manufacturers and service providers. Such a competition forces NDT service providers to deliver the highest quality and most reliable results at a reasonable price to their clients. NDT beneficiaries such as oil and gas, and power generation sectors through their quality system such as ISO 9001 Version 2000 demand that the quality system adopted by organizations providing services to them must be evaluated. Such requirement leave NDT services companies with no option except to have them accredited. As for today, the most logical accreditation scheme applicable to NDT organizations is the ISO 17025. This paper reviews the current status and forecast the need for such an accreditation in Malaysia. (Author)

  2. Preliminary evaluation of a Neutron Calibration Laboratory

    International Nuclear Information System (INIS)

    In the past few years, Brazil and several other countries in Latin America have experimented a great demand for the calibration of neutron detectors, mainly due to the increase in oil prospection and extraction. The only laboratory for calibration of neutron detectors in Brazil is localized at the Institute for Radioprotection and Dosimetry (IRD/CNEN), Rio de Janeiro, which is part of the IAEA SSDL network. This laboratory is the national standard laboratory in Brazil. With the increase in the demand for the calibration of neutron detectors, there is a need for another calibration services. In this context, the Calibration Laboratory of IPEN/CNEN, Sao Paulo, which already offers calibration services of radiation detectors with standard X, gamma, beta and alpha beams, has recently projected a new calibration laboratory for neutron detectors. In this work, the ambient equivalent dose rate (H⁎(10)) was evaluated in several positions inside and around this laboratory, using Monte Carlo simulation (MCNP5 code), in order to verify the adequateness of the shielding. The obtained results showed that the shielding is effective, and that this is a low-cost methodology to improve the safety of the workers and evaluate the total staff workload. (author)

    1990-01-01

    Some techniques for laboratory calibration and characterization of video cameras used with frame grabber boards are presented. A laser-illuminated displaced reticle technique (with camera lens removed) is used to determine the camera/grabber effective horizontal and vertical pixel spacing as well as the angle of nonperpendicularity of the axes. The principal point of autocollimation and point of symmetry are found by illuminating the camera with an unexpanded laser beam, either aligned with the sensor or lens. Lens distortion and the principal distance are determined from images of a calibration plate suitably aligned with the camera. Calibration and characterization results for several video cameras are presented. Differences between these laboratory techniques and test range and plumb line calibration are noted.

  12. Air kerma standardization for diagnostic radiology, and requirements proposal for calibration laboratories

    International Nuclear Information System (INIS)

    The demand for calibration services and quality control in diagnostic radiology has grown in the country since the publication of the governmental regulation 453, issued by the Ministry of Health in 1998. At that time, to produce results facing the new legislation, many laboratories used different standards and radiation qualities, some of which could be inadequate. The international standards neither supplied consistent radiation qualities and standardization for the different types of equipment available. This situation changed with the publication of the new edition of the IEC 61267 standard, published in 2005. A metrology network was created, but it is not yet accredited by the accreditation organism of the country, INMETRO. The objective of this work was to implement the standardization of the air kerma for the un attenuated qualities (RQR) of IEC 61267, and to develop a requirement proposal for instruments calibration laboratories. Results of interlaboratory comparisons demonstrate that the quantity is standardized and internationally traceable. A laboratory requirement proposal was finalized and it shall be submitted to INMETRO to be used as auxiliary normative document in laboratory accreditation. (author)

  13. Meta-audit of laboratory ISO accreditation inspections: measuring the old emperor's clothes.

    Wilson, Ian G; Smye, Michael; Wallace, Ian J C

    2016-02-01

    Accreditation to ISO/IEC 17025 is required for EC official food control and veterinary laboratories by Regulation (EC) No. 882/2004. Measurements in hospital laboratories and clinics are increasingly accredited to ISO/IEC 15189. Both of these management standards arose from command and control military standards for factory inspection during World War II. They rely on auditing of compliance and have not been validated internally as assessment bodies require of those they accredit. Neither have they been validated to criteria outside their own ideology such as the Cochrane principles of evidence-based medicine which might establish whether any benefit exceeds their cost. We undertook a retrospective meta-audit over 14 years of internal and external laboratory audits that checked compliance with ISO 17025 in a public health laboratory. Most noncompliances arose solely from clauses in the standard and would not affect users. No effect was likely from 91% of these. Fewer than 1% of noncompliances were likely to have consequences for the validity of results or quality of service. The ISO system of compliance auditing has the performance characteristics of a poor screening test. It adds substantially to costs and generates more noise (false positives) than informative signal. Ethical use of resources indicates that management standards should not be used unless proven to deliver the efficacy, effectiveness, and value required of modern healthcare interventions.

    Full Text Available Background: The improvment of the quality of testing services in public laboratories is a high priority in many countries. Consequently, initiatives to train laboratory staff on quality management are being implemented, for example, the World Health Organization Regional Headquarters for Africa (WHO-AFRO Strengthening Laboratory Management Towards Accreditation (SLMTA. Mentorship may be an effective way to augment these efforts. Methods: Mentorship was implemented at four hospital laboratories in Lesotho, three districts and one central laboratory, between June 2009 and December 2010. The mentorship model that was implemented had the mentor fully embedded within the operations of each of the laboratories. It was delivered in a series of two mentoring engagements of six and four week initial and follow-up visits respectively. In total, each laboratory received 10 weeks mentorship that was separated by 6–8 weeks. Quality improvements were measured at baseline and at intervals during the mentorship using the WHO-AFRO Strengthening Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist and scoring system. Results: At the beginning of the mentorship, all laboratories were at the SLIPTA zero star rating. After the initial six weeks of mentorship, two of the three district laboratories had improved from zero to one (out of five star although the difference between their baseline (107.7 and the end of the six weeks (136.3 average scores was not statistically significant (p = 0.25. After 10 weeks of mentorship there was a significant improvement in average scores (182.3; p = 0.034 with one laboratory achieving WHO-AFRO three out of a possible five star status and the two remaining laboratories achieving a two star status. At Queen Elizabeth II (QE II Central Laboratory, the average baseline score was 44%, measured using a section-specific checklist. There was a significant improvement by five weeks (57.2%; p = 0.021.

  15. Quality management system and accreditation of the in vivo monitoring laboratory at Karlsruhe Inst. of Technology

    International Nuclear Information System (INIS)

    The in vivo monitoring laboratory (IVM) at Karlsruhe Inst. of Technology (KIT), with one whole body counter and three partial-body counters, is an approved lab for individual monitoring according to German regulation. These approved labs are required to prove their competencies by accreditation to ISO/IEC 17025:2005. In 2007 a quality management system (QMS), which was successfully audited and granted accreditation, was set up at the IVM. The system is based on the ISO 9001 certified QMS of the central safety department of the Research Centre Karlsruhe the IVM belonged to at that time. The system itself was set up to be flexible and could be adapted to the recent organisational changes (e.g. founding of KIT and an institute for radiation research) with only minor effort. (authors)

    2010-09-01

    Medical laboratories, and specifically genetic testing laboratories, provide vital medical services to different clients: clinicians requesting a test, patients from whom the sample was collected, public health and medical-legal instances, referral laboratories and authoritative bodies. All expect results that are accurate and obtained in an efficient and effective manner, within a suitable time frame and at acceptable cost. There are different ways of achieving the end results, but compliance with International Organization for Standardization (ISO) 15189, the international standard for the accreditation of medical laboratories, is becoming progressively accepted as the optimal approach to assuring quality in medical testing. We present recommendations and strategies designed to aid genetic testing laboratories with the implementation of a quality management system, including key aspects such as document control, external quality assessment, internal quality control, internal audit, management review, validation, as well as managing the human side of change. The focus is on pragmatic approaches to attain the levels of quality management and quality assurance required for accreditation according to ISO 15189, within the context of genetic testing. Attention is also given to implementing efficient and effective quality improvement. PMID:20720559

  19. Accreditation of testing laboratories in dosimetry: The use of a flexible scope at the competent Incorporation Measuring Body Juelich

    International Nuclear Information System (INIS)

    The accreditation of the Competent Incorporation Measuring Body at Juelich includes incorporation monitoring by means of direct measurements of the body activity as well as by means of indirect determination of the body activity by radiochemical analysis of excreta samples. In both testing areas, it proved to be very useful to have a flexible scope. In particular, the associated freedom in choosing testing procedures supports the continual improvement process of the laboratory. The modification of existing methods as well as the development and introduction of new procedures makes an immediate reaction to changed requirements feasible. At Juelich the use made out of the flexible scope included, e.g. the introduction of mathematical calibration in whole-body counting and the automation of sample preparation in radiochemical analysis. Advantages of the new procedures and modified methods include on the one hand the reduction of processing times, downtimes and hazard potentials on the other hand enhanced detection limits and improved cost-efficiency. In the result, it can be recommended to other qualified testing laboratories to go for a flexible scope. (authors)

    The recent revision of ISO15189 has further strengthened its position as the standard for accreditation for medical laboratories. Both for laboratories and their customers it is important that the scope of such accreditation is clear. Therefore the European co-operation for accreditation (EA) demands that the national bodies responsible for accreditation describe the scope of every laboratory accreditation in a way that leaves no room for doubt about the range of competence of the particular laboratories. According to EA recommendations scopes may be fixed, mentioning every single test that is part of the accreditation, or flexible, mentioning all combinations of medical field, examination type and materials for which the laboratory is competent. Up to now national accreditation bodies perpetuate use of fixed scopes, partly by inertia, partly out of fear that a too flexible scope may lead to over-valuation of the competence of laboratories, most countries only use fixed scopes. The EA however promotes use of flexible scopes, since this allows for more readily innovation, which contributes to quality in laboratory medicine. In this position paper, the Working Group Accreditation and ISO/CEN Standards belonging to the Quality and Regulation Committee of the EFLM recommends using an approach that has led to successful introduction of the flexible scope for ISO15189 accreditation as intended in EA-4/17 in The Netherlands. The approach is risk-based, discipline and competence-based, and focuses on defining a uniform terminology transferable across the borders of scientific disciplines, laboratories and countries.

  2. The role of the EPA radiation quality assurance program in the measurement quality assurance accreditation program for radioassay laboratories

    International Nuclear Information System (INIS)

    As the nature and extent of radiological contamination becomes better documented and more public, radioanalytical laboratories are faced with a constantly expanding variety of new and difficult analytical requirements. Concurrent with those requirements is the responsibility to provide customers, regulatory officials, or the public with defensible data produced in an environment of verifiable, controlled quality. To meet that need, a quality assurance accreditation program for radioassay laboratories has been proposed by the American National Standards Institute (ANSI). The standard will provide the organizational framework and functional requirements needed to assure the quality of laboratory outputs. Under the proposed program, the U.S. Environmental Protection Agency's (EPA's) Laboratory Intercomparison Program plays a key role as a reference laboratory. The current and proposed roles of the EPA Intercomparison Program are discussed, as are the functional relationships between EPA, the accreditating organization, and the service and monitoring laboratories

    The Conference of Radiation Control Program Directors, or CRCPD, first became involved in a calibration laboratory accreditation program about 17 years ago. Since that time, the CRCPD has formed a Committee on Ionizing Measurements which writes criteria for the accreditation of laboratories, and performs the accreditation review process. To become accredited, a laboratory must agree to an administrative review, and an onsite review, and participate in measurement quality assurance (MQA) testing with the National Institute of Standards and Technology (NIST). The CRCPD currently has four accredited laboratories. All the laboratories are working with the Conference in promoting the improvement of MQA in radiation control programs.

  8. Laboratory geometric calibration of areal digital aerial camera

    International Nuclear Information System (INIS)

    Digital aerial camera is non-metric camera. Geometric calibration, including the determination of interior orientation elements and distortion parameters, is the base of high precision photogrammetry. In this paper, a laboratory geometric calibration system of areal digital aerial cameras is developed. This system uses a collimator and a star tester as the target generator. After measurement of the coordinates of targets on the CCD plane and corresponding angles of parallel lights, the geometric calibration of digital aerial camera can be realized according to the geometric calibration model of this paper. Geometric calibration experiments are taken out based on this system using two kinds of mainstream digital aerial cameras, Cannon EOS 5D Mark II and Hasselblad H3D. Experiment results show that this system can satisfy the calibration requirements of aerial photogrammetric application and prove the correctness and the reliability of this calibration method

  9. Calibration of laboratory equipment and its intermediate verification

    International Nuclear Information System (INIS)

    When a laboratory wants to prove that he has technical competence to carry out tests or calibrations must demonstrate that it has complied with certain requirements that establish , among others, the mandatory : calibrate or verify equipment before putting it into service in order to ensure that it meets to the specifications of laboratory equipment to keep records evidencing the checks that equipment complies with the specification ; perform intermediate checks for maintain confidence in the calibration status of the equipment , ensure that the operation is checked and calibration status of equipment when the equipment goes outside the direct control of the laboratory , before be returned to service, establish a program and procedure for the calibration of equipment; show how determined the calibration periods of their equipment as well as evidence that intermediate checks are suitable for the calibration periods. However, some confusion is observed as to the meaning of the terms 'calibration' and 'verification' of a computer. This paper analyzes applicable documentation and suggests that the differences are generated in part by translations and by characterization concepts upon its usage, that is, if it is legal metrology or assessment conformity. Therefore, this study aims to characterize both concepts , fundamentals to zoom distinguish , outline appropriate strategies for calibration and verification activities to ensure the compliance with regulatory requirements

  13. Project of an integrated calibration laboratory of instruments at IPEN

    International Nuclear Information System (INIS)

    The Calibration Laboratory of Instruments of Instituto de Pesquisas Energeticas e Nucleares offers calibration services of radiation detectors used in radioprotection, diagnostic radiology and radiotherapy, for IPEN and for external facilities (public and private). One part of its facilities is located in the main building, along with other laboratories and study rooms, and another part in an isolated building called Bunker. For the optimization, modernization and specially the safety, the laboratories in the main building shall be transferred to an isolated place. In this work, a project of an integrated laboratory for calibration of instruments was developed, and it will be an expansion of the current Calibration Laboratory of Instruments of IPEN. Therefore, a series of radiometric monitoring of the chosen localization of the future laboratory was realized, and all staff needs (dimensions and disposition of the study rooms and laboratories) were defined. In this project, the laboratories with X ray equipment, alpha and beta radiation sources were located at an isolated part of the building, and the wall shielding was determined, depending on the use of each laboratory.

  14. The Brazilian experience on the integrated authorization of individual monitoring systems and calibration laboratories of equipment used in radiation protection

    International Nuclear Information System (INIS)

    In Brazil, the National Commission for Nuclear Energy gives formal authorization of operation for Individual Monitoring Services and for Calibration Facilities for Equipment Used in Radiation Protection. The responsibility for recommending these authorizations has been delegated to the Institute for Radiation Protection and Dosimetry which, until 2005, had two separate committees operating in each area of authorization, namely IMS and calibration laboratories. Both committees had the responsibility of defining the requirements for authorization, auditing the laboratories, organizing inter-comparison exercises, certifying the heads of the laboratories and of recommending the authorization or cessation of laboratories activities to the direction of the institute. In the year 2005 a single integrated committee was formed to perform both kinds of authorization, which was named Committee for the Evaluation of Services of Essays and Calibration (CASEC). With a different philosophy in mind, this new group focuses only on the certification of compliance with the authorization regulation, leaving the definition of these rules to independent groups named technical chambers that should be formed by experts, who are not necessarily staff, according to specific needs. At present, CASEC is starting to require accreditation on ISO standard 17025 for both kinds of laboratories as a prerequisite for the authorization. This paper presents the difficulties faced during the process of transition from one system of authorization to the other, the present status of the system of individual monitoring systems and calibration facilities and results of inter-laboratory comparison exercises.

    1993-12-31

    The Calibration Laboratory attempts to provide services that satisfy the needs and requests for a variety of customers. New needs and requests have resulted in calibration of instrumentation outside the original laboratory designs. These tasks require several changes at the laboratory and a need for new support services, especially measurement quality assurance (MQA). The MQA tests are gamma (Cs-137) below 0.5 mrem (5{mu}Sv) per hour and x-ray kVp. Modification to the current gamma (Cs-137) MQA test is recommended because lower intensity fields are commonly measured.

    International Nuclear Information System (INIS)

    The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

  17. A simple laboratory-based radon calibration system

    International Nuclear Information System (INIS)

    Measurements of 222Rn ('radon') in the environment are important in the geosciences and radiation-protection fields. We demonstrate here a simple laboratory-based calibration system to evaluate the efficiency of radon detectors with a reproducibility of about ±2%. The system uses a closed-loop air circulation design with 226Ra adsorbed onto MnO2-impregnated fiber as a radon source. Two RAD7 radon detectors (Durridge Co., Inc.) that were precisely calibrated at Durridge's in-house calibration facility are used as secondary standards. By parallel analysis of the radon-enriched air within the closed loop, the test RAD7s are assigned a calibration coefficient to be applied to future measurements. We also performed a side-by-side intercomparison with two RAD7s in a high-radon natural environmental setting (limestone cave in Florida) that produced comparable results. (author)

    Ramos, Manoel Mattos Oliveira

    2009-07-01

    The demand for calibration services and quality control in diagnostic radiology has grown in the country since the publication of the governmental regulation 453, issued by the Ministry of Health in 1998. At that time, to produce results facing the new legislation, many laboratories used different standards and radiation qualities, some of which could be inadequate. The international standards neither supplied consistent radiation qualities and standardization for the different types of equipment available. This situation changed with the publication of the new edition of the IEC 61267 standard, published in 2005. A metrology network was created, but it is not yet accredited by the accreditation organism of the country, INMETRO. The objective of this work was to implement the standardization of the air kerma for the un attenuated qualities (RQR) of IEC 61267, and to develop a requirement proposal for instruments calibration laboratories. Results of interlaboratory comparisons demonstrate that the quantity is standardized and internationally traceable.

    International Nuclear Information System (INIS)

    A quality assurance programme at the National Calibration Laboratory for ionizing radiation in Tanzania is described. The programme focuses mainly on regular stability check source and reference output measurements, performance testing of TLD systems as well as some external audit checks. It is found that the stability check source measurements are within ± 1%. Similarly, the air kerma rate measurements agree well with calibration uncertainties, that is ± 2% for protection level measurements and ± 1.5% for clinical dosimetry. The results of comparison of dose measurements done on site and those obtained from some external audit checks are also within requirements. This shows that the working standards have been kept with good care, and that the traceability to the international measurement system is adequately maintained. Some examples on calibration transfer activities are briefly discussed

    An accurate comparison between the laboratory for the calibration of multifunction electrical instruments of the National Institute of Metrology Research and a secondary high level electrical calibration laboratory was performed with satisfactory results. The instrument involved in the comparison was a top class 81/2 digit multifunction calibrator, chosen for its wide measurement fields and excellent definability. Novelties of this work are the wideness of the compared fields measured with high accuracy despite being a commercial instrument and the identification of criterions to evaluate the degree of correlation between the measurements of the two laboratories. The calibrator resulted suitable to adequately verify the capabilities of high level secondary electrical laboratories,

    The Mars Science Laboratory Curiosity rover carries a basalt calibration target for monitoring the performance of the alpha particle X-ray spectrometer. The spectrum acquired on Sol 34 shows increased contributions from Mg, S, Cl and Fe relative to laboratory spectra recorded before launch. Mars Hand Lens Imager images confirm changes in the appearance of the surface. Spectra taken on Sols 179 and 411 indicate some loss of the deposited material. The observations suggest deposition of a surface film likely consisting of dust mobilized by impingement of the sky crane's terminal descent engine plumes with surface fines during Curiosity's landing. New APXS software has been used to model the thin film that coated the calibration target on landing. The results suggest that a film of about 100 nm thickness, and containing predominantly MgO, Fe2O3, SO3, Cl and Na2O could give rise to the observed spectral changes. If this film is also present on the alpha particle sources within the APXS, then its effect is negligible and the terrestrial calibration remains appropriate.

  8. Dosimetry through the Secondary Laboratory of Dosimetric Calibration of Mexico

    International Nuclear Information System (INIS)

    In the beginnings of the sixty years an urgent necessity is presented mainly in the developing countries, of improving in important form the accuracy in the dosimetry of external faces in therapy of radiations (radiotherapy centers), mainly in the calibration of clinical dosemeters. In 1976 the International Atomic Energy Agency, (IAEA), and the World Health Organization, (WHO), they carried out a mutual agreement with regard to the establishment and operation of a net of Secondary Patron Laboratories of Dosimetry, (LSCD). The necessity to establish measure patterns in the field of the dosimetry of the ionizing radiations, is necessary, to have an accuracy but high in the dosimetry of the radiation beams in therapy which is highly dependent of the dose given to the tumor of those patient with cancer. Similar levels of accuracy are required in protection measures to the radiation with an acceptable smaller accuracy, however, when the personal dosemeters are used to determine the doses received by the individuals under work conditions, such mensurations in therapy of radiations and radiological protection will have traceability through a chain of comparisons to primary or national patterns. The traceability is necessary to assure the accuracy and acceptability of the dosimetric measures, as well as, the legal and economic implications. The traceability is also necessary in the dosimetry of high dose like in the sterilization of different products. The main function of the LSCD is to provide a service in metrology of ionizing radiations, maintaining the secondary or national patterns, which have a traceability to the International System of measures, which is based for if same in the comparison of patterns in the Primary Laboratories of Dosimetry (LPD) under the auspice of the International Office of Weights and Measure (BIPM). The secondary and national patterns in the LSCD constitute in Mexico, the national patterns of the magnitudes in the dosimetry of the ionizing

  10. Operating experience of the Enresa Calibration Laboratory at the El Cabril Disposal Facility

    International Nuclear Information System (INIS)

    At its Low and Intermediate Level Radioactive Waste Disposal Facility at El Cabril (Cordoba) Enresa (the Spanish radioactive waste management agency) has a laboratory for the calibration of protection monitoring instruments. This laboratory was set up in 1997 and procedures for the calibration of radiation metering beams and equipment were developed. The laboratory is equipped with different radioactive sources, standard equipment, and a data-processing system to facilitate periodic calibration, data acquisition and treatment on the basis of the procedure developed. Initially two of the available beams were calibrated. Afterwards a third being calibrated to increase the range of exposure rate levels available. Controls are performed periodically on the laboratory and its equipment to ensure optimum operability. Over the years the radiation monitors and probes used at the Cabril disposal facility have been calibrated with the frequency indicated in the in-house procedures of the installation. Likewise, since the calibration laboratory of Vandellos 1 Nuclear Power Plant ceased to operate as a result of the dismantling of the installation, performed by Enresa. The monitors, probes and electronic dosimeters have been calibrated and used since then for radiological protection purposes, during continuation of the dismantling work at Vandellos 1 and in accordance with the equipment calibration programme of the plant's Radiological Protection Service. In addition, equipment has been calibrated for use in other Enresa operations. Finally, this calibration laboratory has irradiated certain component with printed circuits developed within the framework of an Enresa research project. The objective is to study the possibility of incorporating them in radioactive waste containers with technical information of the waste contained in them. The aim is to probe their resistance to the levels of radiation to which they may be subjected and whether the information incorporated is

  15. Two laboratory methods for the calibration of GPS speed meters

    International Nuclear Information System (INIS)

    The set-ups of two calibration systems are presented to investigate calibration methods of GPS speed meters. The GPS speed meter calibrated is a special type of high accuracy speed meter for vehicles which uses Doppler demodulation of GPS signals to calculate the measured speed of a moving target. Three experiments are performed: including simulated calibration, field-test signal replay calibration, and in-field test comparison with an optical speed meter. The experiments are conducted at specific speeds in the range of 40–180 km h−1 with the same GPS speed meter as the device under calibration. The evaluation of measurement results validates both methods for calibrating GPS speed meters. The relative deviations between the measurement results of the GPS-based high accuracy speed meter and those of the optical speed meter are analyzed, and the equivalent uncertainty of the comparison is evaluated. The comparison results justify the utilization of GPS speed meters as reference equipment if no fewer than seven satellites are available. This study contributes to the widespread use of GPS-based high accuracy speed meters as legal reference equipment in traffic speed metrology. (paper)

    Full Text Available A new Field Imaging Spectrometer System (FISS based on a cooling area CCD was developed. This paper describes the imaging principle, structural design, and main parameters of the FISS sensor. The FISS was spectrally calibrated with a double grating monochromator to determine the center wavelength and FWHM of each band. Calibration results showed that the spectral range of the FISS system is 437–902 nm, the number of channels is 344 and the spectral resolution of each channel is better than 5 nm. An integrating sphere was used to achieve absolute radiometric calibration of the FISS with less than 5% calibration error for each band. There are 215 channels with signal to noise ratios (SNRs greater than 500 (62.5% of the bands. The results demonstrated that the FISS has achieved high performance that assures the feasibility of its practical use in various fields.

  3. Radiation protection aspects of calibration laboratory for radiation monitoring instruments

    International Nuclear Information System (INIS)

    Radiation sources are widely used in various fields such as Medical, Industrial and Research etc. It is inevitable that radiation exposures will be received by the users of these radiation sources while handling the sources. It is essential to keep these exposures within the prescribed dose limits by the Atomic Energy Regulatory Board (AERB) to safe guard the radiation workers from the hazardous effects of radiation. Hence, the user institutions need to measure the radiation levels in and around the radiation installations using appropriate radiation monitoring instruments. There are several hundreds of Radiation Monitoring Instruments (RMIs) such as hand held radiation survey meters (RSM), area monitors, direct reading dosimeters (DRDs), secondary standard dosimeters (SSD) are being used by radiation facilities. Properly calibrated RMIs will provide the necessary confidence to the users of radiation sources in assessing the hazard potential. Periodic calibration of RMIs is a requirement under the Atomic Energy (Radiation Protection) Rules. As the number of users and in turn RMIs has been continuously increasing, AERB has initiated several regulatory measures in ensuring safe handling of radiation sources as well as establishment of calibration facilities

  4. Laboratory and field portable system for calibrating airborne multispectral scanners

    International Nuclear Information System (INIS)

    Manufacturers of airborne multispectral scanners suggest procedures for calibration and alignment that are usually awkward and even questionable. For example, the procedures may require: separating the scanner from calibration and alignment sources by 100 feet or more, employing folding mirrors, tampering with the detectors after the procedures are finished, etc. Under the best of conditions such procedures require about three hours yielding questionable confidence in the results; under many conditions, however, procedures commonly take six to eight hours, yielding no satisfactory results. EG and G, Inc. has designed and built a calibration and alignment system for airborne scanners which solves those problems, permitting the procedures to be carried out in about two to three hours. This equipment can be quickly disassembled, transported with the scanner in all but the smallest single engine aircraft, and reassembled in a few hours. The subsystems of this equipment are commonly available from manufacturers of optical and electronic equipment. The other components are easily purchased, or fabricated. The scanner discussed is the Model DS-1260 digital line scanner manufactured by Daedalus Enterprises, Inc. It is a dual-sensor system which is operated in one of two combination of sensors: one spectrometer head (which provides simultaneous coverage in ten visible channels) and one thermal infrared detector, or simply two thermal infrared detectors

  5. An accredited infrastructure for clearance of decommissioning waste

    International Nuclear Information System (INIS)

    The nuclear research reactors and a hot-cell facility at the Riso site in Denmark have been closed and are in the process of being decommissioned. This has prompted the development of an accredited infrastructure called the Clearance Function. This function is responsible for the activity concentration measurements of the clearance candidates and for the demonstration of compliance with the clearance levels for the released objects. The Clearance Function comprises laboratory facilities, measuring equipment, measuring procedures, waste handling software, software for clearance related calculations and trained personnel. An accreditation of the Clearance Function has been granted from the accreditation body, DANAK, according to the international standard ISO/IEC 17025:2005. DANAK is a member of ILAC, the International Laboratory Accreditation Cooperation. The Clearance Function has been accredited to measure surface-specific and mass-specific activities using surface contamination monitors and high purity germanium detectors. The germanium detectors are characterised and in each measurement they are calibrated using the ISOCS (registered) calibration software. Activity concentration measurements can be made on items as a whole (one or several combined measurements) or on samples from an item. In the latter case a statistical method is used to evaluate whether the activity concentration is above or below the clearance level. The paper describes the different elements of the Clearance Function and the processing of items through the flow routes depending on the likely activity content and the distribution of activity. It is shown how uncertainties are incorporated in the clearance criteria. Experience from the first year of operation of the Clearance Function is reported. (author)

  9. Assuring the quality of the mammography calibrations in Cuban laboratory by comparison with Greek dosimetry standard

    International Nuclear Information System (INIS)

    The Secondary Standard Dosimetry Laboratory (SSDL) of Cuba has recently worked on preparation of the dissemination proposal of air kerma quantities for dose measurements at mammography beams into the country. This work was supported by IAEA coordinated research project. The X-ray equipment available at the laboratory is based on tungsten anode, and then the recommended RQR-M series based on molybdenum target and specified in IEC 61267 cannot be established at the SSDL. The calibration of the reference class chamber with flat response in any beams on mammography range is an option suggested in TRS 457 when not all radiation qualities are available. As an alternative some authors have suggested the use of radiation qualities based on tungsten anode and defined by IEC 1223-3-2, The Radcal 10X6M chamber was designated as secondary standard of the SSDL. The chamber was calibrated over the IEC 1223-3-2 range in the primary laboratory of Austria (BEV). The designation and calibration of the secondary standard was followed by the establishment of the IEC 1223-3-2 qualities at the SSDL of Cuba and preparation of the calibration procedures. Before introducing the calibrations by alternative method it was necessary to test the quality of the results provided by SSDL of Cuba to confirm both if this procedure can be properly operated by laboratory and the needs of customer are met. For this goal it was found the experienced laboratory from Greece that use appropriate X-ray spectra for calibration of mammography dosimeters. The Hellenic Ionizing Radiation Calibration Laboratory (HIRCL) of Greece maintains the MAGNA Ref 92650 chamber as secondary standard traceable to PTB in RQR-M qualities based on molybdenum target. The X-ray system used is the clinical mammography unit with some modifications to fit the needs of calibrations. The laboratories were agreed to initiate a bilateral comparison exercise to evaluate whether the results of calibration of both laboratories are similar

    This work is part of a cooperation plan between the LNMRI/IRD and the LCR/UERJ, for the a primary calibration at the IRD and a secondary laboratory at the LCR, both calibrated for mammographic beams which will be part a Calibration National Network. For the mounting of the primary laboratory, the first step was to install two additional collimators in order to guarantee that the beam area over the ionization chamber to satisfy the calibration international standards. So, the collimators were constructed obeying the geometric rules, the first being of conic format and the second of the cylindrical format, therefore avoiding the effects of the scattering radiation on the edges. By using this collimation system it was possible to verify the uniformity of the radiation field incident the ionization chamber to be over 98% of the total area, guaranteeing better precision of the measurement

  14. The U.S. Department of Energy Laboratory Accreditation Program for testing the performance of extremity dosimetry systems: a summary of the program status

    International Nuclear Information System (INIS)

    In 1986, The U.S. Department of Energy (DOE) implemented a program to test the performance of its personnel whole-body dosimetry systems. This program was the DOE Laboratory Accreditation Program (DOELAP). The program parallels the performance testing program specified in the American National Standard for Dosimetry - Personnel Dosimetry Performance -Criteria for Testing (ANSI N13.11-1983), but also addresses the additional dosimetry needs of DOE facilities. As an extension of the whole-body performance testing program, the DOE is now developing a program to test the performance of personnel extremity dosimetry systems. The draft DOE standard for testing extremity dosimetry systems is much less complex than the whole-body dosimetry standard and reflects the limitations imposed on extremity dosimetry by dosimeter design and irradiation geometry. A pilot performance test session has been conducted to evaluate the proposed performance-testing standard. (author)

  15. Standardization of the calibration of brachytherapy sources at the IAEA dosimetry laboratory

    International Nuclear Information System (INIS)

    A new service to SSDLs has been initiated at the IAEA Dosimetry Laboratory for providing calibrations of well-type ionisation chambers, used in brachytherapy applications, which are traceable to the International Measurement System. Considering that the most common radionuclide used in the developing countries is 137Cs, two such sources of the type used for gynaecological intracavitary applications have been purchased by the Agency and calibrated at the National Institute of Standards and Technology (NIST), USA. These 137Cs reference sources together with a well-type ionization chamber constitute the IAEA brachytherapy dosimetry standard. Based on the recommendations by a group of experts, a method has been developed for transferring calibrations to SSDLs which is described in this paper. The method is based on the acquisition by the SSDLs of sources and equipment similar to those at the IAEA. The well-type chamber is to be calibrated at the IAEA Dosimetry Laboratory, and this will be used at the SSDL to calibrate its own reference sources. These sources can in turn by used to calibrate well-type chambers from hospital users and to calibrate other type of sources by performing measurements in air. In order to standardize the procedures for the two methods and to provide guidance to the SSDLs, measurements have been carried out at the IAEA Dosimetry Laboratory. The reproducibility of the two type of measurements has been found to be better than 0.5%, and the uncertainty of calibrations estimated to be less than 1.5% (one standard deviation).

    The public institution aims to promote excellence in public management to contribute to the quality of services provided to its customers and to increase competitiveness in the country, as well as its international projection. A technical barrier to trade that can lead to dissatisfaction and achieve the reputation of the institution is failing the test or calibration results and measurement data, thereby accreditation is regarded as the first essential step to facilitate the mutual acceptance of test results and calibration or measurement data. For recognition, laboratories need to demonstrate full compliance with both the sections of ISO/IEC 17025:2005, i.e. management and technical requirements. This research aims to discuss the critical aspects for implementation of ABNT NBR ISO / IEC 17025:2005 for calibration and testing of a Public Institution seeking accreditation of its laboratories with INMETRO, national accreditation body Laboratories. Besides getting preventive, corrective and improvement actions continues guidelines. Furthermore, the methodology used was to conduct a literature search and apply a questionnaire to identify the degree of agreement / disagreement of the foundations of the standard servers. Analysis of the results showed that the critical issues were: commitment, training, resources (infrastructure, human) and culture. (author)

  17. Calibration of survey meters at the Algerian Secondary Standard Dosimetry Laboratory

    International Nuclear Information System (INIS)

    Full text: The Algerian Secondary Standard Dosimetry Laboratory, which became a Regional AFRA Designated Centre for French spoken countries, in the field of calibration since 2005, has developed and implemented methodologies for the calibration of radiation protection instruments such as survey meters. These instruments were initially calibrated in terms of air kerma free in air (NK) in 60Co, 137Cs gamma radiations. Although the recommended calibration quantity is H*(10) (Sv/h), most of instruments measure different physical quantities and problems about the expression of calibration factor in the calibration certificates are always raised. In order to switch to calibrations in terms of H*(10), a feasibility study was performed using instruments submitted for calibration at the SSDL. This paper presents the variation of the calibration coefficients, Fc, obtained since 2005 for three types of survey meters. The uncertainty components involved in the determination of Fc are analysed in details. Material and method: This study included the most used survey meters in Algeria and received at the SSDL in 2005 and 2006 which consist of 127 survey-meters of type Automess (different models), 80 Ludlum model 3 and 23 Graetz X 5 DE. Calibrations were performed using the beam output decay method. This output was determined with the Reference Standard chamber of type NE 2575 in 2005 and LS01 in 2006, both calibrated at the IAEA calibration laboratory. The average calibration coefficients, Fc, which converts the instruments reading to ambient equivalent absorbed dose, are calculated and the relative standard deviations assessed. The variation of calibration coefficients, for each type of instruments, is compared to the overall stated uncertainty for this coefficient. Results and discussion: The mean calibration coefficients in terms of H*(10) were lying from 0.993 ± 2.55% and 1.039 ± 3.16% for the Automess survey meters and from . The results are 1.215 ± 5.93%, 1.149 ± 14

    International Nuclear Information System (INIS)

    New diagnostic X-ray beams based on the IEC standard no. 1267 are now available at the Secondary Standard Dosimetry Laboratory in Sweden. These beams are alternatives to the ISO narrow qualities and BIPM qualities that until now have been used for calibration of diagnostic instruments. A procedure differing somewhat from the IEC standard but following the primary radiation standards laboratory at PTB has been used for defining the radiation quality. This report describes the characteristics of the new radiation beams and the estimated effect on calibration factors due to the change in radiation quality. The effect on existing calibration beams due to the reconstruction of filter wheels has been investigated concerning scattered radiation, half-value layers and air kerma rates

  4. Mammography calibration facility in Medical Physics Laboratory, Malaysian Institute for Nuclear Technology Research (MINT)

    International Nuclear Information System (INIS)

    A facility for mammography calibration is being established in the Medical Physics Laboratory, Malaysian Institute for Nuclear Technology Research (MINT). A mammography x-ray machine model MF-150G (maximum rating 150 mA 35 kV) fitted with 30 micron Molybdenum (Mo) filter is used as an x-ray radiation source for mammography calibration. Five radiation qualities are selected for calibration purpose namely 23, 25, 28, 30 and 35 kV, which are selectable from the control panel of the x-ray machine. Important parameters that are set for this calibration facility are exposure time, tube current, focus to dosemeter distance (FDD) and beam size at specified distance. Typical FDD and beam size values are 40 cms and 10x10 cm2. The room temperature and pressure are recorded by using barometer and thermometer model Lambrecht (Type 00.06040.100000 No:670699.0001). First and second half value layer of the beam are measured by using the Aluminum Half Value Layer Attenuator Set of type Gammex RMI 115A which consists of a few 0.1mm and 0.5mm thickness Aluminium attenuators. A RadCal measuring system is used as a standard measuring equipment. For kV measurement, a Radiation Monitor Controller Model 9010 (SN:90-2021) is connected to Accu-kV control unit Model 4081 (SN: 41-0455) and Accu-kV sensor model 40X5-Mo (S/N: 48-0602). For dose measurement the RadCal Radiation Monitor Controller Model 9010 is connected to a unit converter Model 9060 (S/N: 99-1137) and ion chamber Model 10X5/6M (S/N: 8789). The standard measuring system is used to ensure calibration traceability to primary standard laboratories. This measuring system is capable of measuring dose up to 600Gy, kV up to 40kV and measuring exposure time up to 500 milliseconds. The typical dose rate of x-ray radiation at FDD 40 cms is about 650 mGy/min at 27 kV and 12.5 mAs. Substitution method is used for calibration of user's instruments. Chamber model 10X5-6M (S/N: 8789) is used as a standard chamber to measure the mammography x

  5. Laboratory for the Dosimetric Equipment Calibration at the Institute of Nuclear Physics in Cracow

    International Nuclear Information System (INIS)

    A new calibration laboratory has been developed at the INP, Cracow, Poland. The laboratory is located in a hall of dimension 9 m (length) x 4 m (wide) x 4.5 m (height). For calibration purposes the Cs-137 source of activity 185 MBq / 5 Ci / is applied, placed in the 16 cm thick lead capsule. The beam is collimated using a collimator with a constant opening of 20o. The source is placed 2 m above the ground to avoid albedo scattering. This source covers a dose rate range from 17 mGy/h to 290 μGy/h. For low-dose calibration 0.05 Ci source is applied. The positioning of the source and opening of the collimator is pneumatically controlled. The dosimeters to be calibrated are placed onto a vehicle with DC motor positioned by PC computer. The vehicle is remotely positioned with the precision of one millimetre at the distance from the source between 1 and 7 meters. The vehicle positioning is controlled electronically and additionally checked via TV-camera. Exact dosimeter positioning is performed with a medical cross-laser and with a telescope device. The construction of the vehicle allows for performing of angular irradiations. On the axis of the vehicle 320 keV Phillips X-ray tube is installed which may be used as an irradiation source. UNIDOS dosimeter with PTW ionisation chambers is used for determination of the dose rate. This calibration stand is designed for calibration of personal dosimeters, calibration of active devices for radiation protections and for research on the newly developed thermoluminescent materials.

    A primary reference solar cell calibration technique recently established at the Korea Institute of Energy Research in Korea is introduced. This calibration technique is an indoor method that uses a highly collimated continuous-type solar simulator and absolute cavity radiometer traceable to the World Radiometric Reference. The results obtained using this calibration technique are shown with a precise uncertainty analysis, and the system configuration and calibration procedures are introduced. The calibration technique avoids overestimating the short-circuit current of a reference solar cell due to multiple reflections of incident simulator light using a novel method. In addition, the uncertainty analysis indicates that the calibration technique has an expanded uncertainty of approximately 0.7% with a coverage factor of k = 2 for a c-Si reference cell calibration. In addition, the developed primary reference solar cell calibration technique was compared with other techniques established in the World Photovoltaic Scale (WPVS) qualified calibration laboratories to verify its validity and reliability.

  9. X radiation qualities characterization following the standard IEC 61267 recommendations at the calibration laboratory of IPEN

    International Nuclear Information System (INIS)

    This work presents a methodology for the X radiation qualities characterization following the new recommendations of the standard 61267 of the International Electrotechnical Commission (IEC) to establish a new procedure for calibration of dosimetric systems used in the field of diagnostic radiology. The reference qualities radiation of IEC 61267: RQR 2 to RQR 10, RQA 2 to RQA 10, RQB 2 to RQB 10 and RQN 2 to RQN 10 were implanted at the calibration laboratory of IPEN (LCI). Their characteristics were analyzed through measurements of beam parameters such as: Practical peak voltage (PPV), specific additional filtrations for each qualities (high purity aluminum of about 99.9%), 1st and 2nd Half Value Layers, homogeneity coefficient. The inherent filtration of the X ray tube was also determined. With the establishment of these radiation qualities, the LCI will be ready to calibrate the measuring instruments of radiation in the new qualities, allowing an improvement in radiological services offered by IPEN.

  10. The FAO/IAEA External Quality Assurance Programme (EQAP) and movement towards a generic veterinary diagnostic testing laboratory accreditation scheme. Report of an FAO/IAEA consultants meeting

    International Nuclear Information System (INIS)

    establish a network of national veterinary diagnostic testing laboratories that are recognized for their achievements in establishing QA systems and their proficiency in the use of specific diagnostic assays. This network would facilitate the exchange of epidemiological information and, in the current atmosphere of international and regional trade agreements, provide a greater opportunity to increase the share of developing countries in the international trade of livestock and livestock products. In February 1998, a Consultants' Meeting was convened to consider the design, impact, and proposals for future implementation of the current FAO/IAEA EQAP for Animal Disease Diagnosis and make recommendations with regard to its central purposes and future direction. In addition, the Consultants considered the broader question of a generic QA 'accreditation' scheme for veterinary diagnostic testing laboratories that could be made available through international, regional, or national organizations as appropriate to the country of interest. This broader discussion was stimulated by the fact that few developed and no developing countries have nationally organized schemes to measure and recognize the QA systems and technical competence of veterinary diagnostic testing laboratories, but that such a scheme is of vital importance to the quality of policy decisions and actions taken on national animal health issues and the international trade of livestock and livestock commodities. It followed that, in the Subprogramme's role as a Collaborating Centre to the Office International Epizooties (OIE, or World Animal Health Organization), it would be appropriate to consider the FAO/IAEA EQAP within the broader scope of an international scheme for veterinary diagnostic laboratory accreditation for two reasons: 1) to use information learned through the design and implementation of the FAO/IAEA EQAP to assist in the appropriate development of an international scheme and 2) to ensure that the FAO

  15. Experimental comparison between total calibration factors and components calibration factors of reference dosemeters used in secondary standard laboratory dosemeters

    International Nuclear Information System (INIS)

    A quantitative comparison of component calibration factors with the corresponding overall calibration factor was used to evaluate the adopted component calibration procedure in regard to parasitic elements. Judgement of significance is based upon the experimental uncertainty of a well established procedure for determination of the overall calibration factor. The experimental results obtained for different ionization chambers and different electrometers demonstrate that for one type of electrometer the parasitic elements have no influence on its sensitivity considering the experimental uncertainty of the calibration procedures. In this case the adopted procedure for determination of component calibration factors is considered to be equivalent to the procedure of determination of the overall calibration factor and thus might be used as a strong quality control measure in routine calibration.

    2011-01-01

    Full Text Available Very short-lived halocarbons (VSLH such as CH3I, CH2Br2 and CHBr3 provide an important source of reactive halogens to the atmosphere, however high spatial and seasonal variability in their ambient mixing ratios and sea-air fluxes gives rise to considerable uncertainty in global scale emission estimates. One solution to improve global flux estimates is to combine the multitude of individually published datasets to produce a database of collated global halocarbon observations. Some progress towards this has already been achieved through the HalOcAt (Halocarbons in the Ocean and Atmosphere database initiative, however the absence of a common calibration scale for very short-lived halocarbons makes it difficult to distinguish true environmental variations from artefacts arising from differences between calibration methodologies. As such, the lack of inter-calibrations for both air and seawater measurements of very short-lived halocarbons has been identified as a major limitation to current estimations of the global scale impact of these reactive trace gases. Here we present the key findings from the first national UK inter-laboratory comparison for calibrations of the halocarbons CH3I, CH2Br2 and CHBr3. The aim of this inter-calibration was to provide transparency between halocarbon calibrations from major UK research institutions, an important step towards enabling all measurements from these institutions to be treated as one coherent integrated dataset for global source term parameterisations.

  20. Comparison of calibration coefficients in the IAEA/WHO network of secondary standards dosimetry laboratories

    International Nuclear Information System (INIS)

    The paper describes the methodology, measurements, evaluation and analysis of the results of the IAEA programme for the comparison of calibration coefficients for radiotherapy dosimetry in the IAEA/World Health Organization network of secondary standards dosimetry laboratories (SSDLs). A pilot study was initiated in 1995 and the comparison programme started in 1997. In this programme ionization chambers that belong to the SSDLs are calibrated sequentially at the SSDL, at the IAEA and again at the SSDL. Since 1997, 42 SSDLs have participated in this comparison programme, although only 34 laboratories have effectively completed the process. The results from six participants were outside the acceptance limit set by the IAEA, but the follow-up process has improved the calibration procedures at these SSDLs. The results of the comparison, grouped according to the traceability of the SSDL measurements, are presented and discussed. As part of its own quality assurance programme, the IAEA participated in a regional comparison organized by the Sistema Interamericano de Metrologia (SIM, the regional metrology organization for the Americas) from 2000 to 2002, in which four SSDLs from Latin America also participated. Taking into account the differences in the primary standards to which the various SSDLs are traceable, the results of the IAEA-SIM comparison show good consistency and demonstrate the robustness of the international measurement system in radiotherapy dosimetry.

  1. Laboratory robotics -- An automated tool for preparing ion chromatography calibration standards

    Energy Technology Data Exchange (ETDEWEB)

    Chadwick, J.L.

    1995-04-01

    This paper describes the use of a laboratory robot as an automated tool for preparing multi-level calibration standards for On-Line Ion Chromatography (IC) Systems. The robot is designed for preparation of up to six levels of standards, with each level containing up to eleven ionic species in aqueous solution. The robot is required to add the standards` constituents as both a liquid and solid additions and to keep a record of exactly what goes into making up every standard. Utilizing a laboratory robot to prepare calibration standards provides significant benefits to the testing environment. These benefits include: accurate and precise calibration standards in individually capped containers with preparation traceability; automated and unattended multi-specie preparation for both anion and cation analytical channels; the ability to free up a test operator from a repetitive routine and re-apply those efforts to test operations; The robot uses a single channel IC to analyze each prepared standard for specie content and concentration. Those results are later used as a measure of quality control. System requirements and configurations, robotic operations, manpower requirements, analytical verification, accuracy and precision of prepared solutions, and robotic downtime are discussed in detail.

  2. Cuban laboratory proficiency test for calibration of well-type chambers using two types of HDR 192Ir sources

    International Nuclear Information System (INIS)

    The proficiency test by inter-laboratory comparisons is the commonly accepted procedure both for validation of the testing methods and assuring the quality of the calibration undertaken by the competence laboratories. The Secondary Standard Dosimetry Laboratory (SSDL) of Cuba is located at the Centro de Proteccion e Higiene de las Radiaciones (CPHR). The SSDL has recently implemented the calibration methodology of well-type chambers using the High Dose Rate 192Ir sources under activities of the technical co-operation project with the International Atomic Energy Agency. The reference standard of CPHR is traceable to the primary standard of the German National Metrology Institute (Physikalisch-Technische Bundesanstalt - PTB). The method used by the secondary laboratory follows the Technical Document 1274. On this method the source available is measured in a well-type chamber calibrated against the primary standard. Because there is no HDR afterloader at the SSDL, the calibration of the client source can be done only in the hospital set-up. The user's chamber is calibrated by means of a calibrated source. This method has the advantage that the measurement set-up is simplified but problems can arise from the use of different source designs during calibration of the secondary standard at the primary laboratory and calibration of the user's chambers at the hospital set-up. The variation of the calibration coefficient of the PTW 33004 chamber due to the use of different sources and adapters has already been measured experimentally. The larger differences can be found near 4%. All those facts reinforced the idea to conduct a proficiency test to demonstrate that the calibration procedure used by SSDL can be applied in practice and will not lead to the incorrect calibration coefficient within the stated uncertainty

    International Nuclear Information System (INIS)

    The National Radiation Laboratory (NRL), serving under the Ministry of Health, provides radiation protection services to the whole of New Zealand. Consequently it performs many functions that are otherwise spread amongst several organizations in larger countries. It is the national regulatory body for radiation protection. It writes and enforces codes of safe practice, and conducts safety inspections of all workplaces using radiation. It provides a personal monitoring service for radiation workers. It also maintains the national primary standards for x-ray exposure and 60Co air kerma. These standards are transferred to hospitals through a calibration service. The purpose of this report is to outline the primary standards facilities at NRL, and to discuss the calibration of dosemeters using these facilities. (J.P.N.)

  4. Risk analysis update of the Radiation Monitor Calibration Laboratory of the Almirante Alvaro Alberto Power Station

    International Nuclear Information System (INIS)

    In 2001, a Probabilistic Safety Assessment (PSA) of the Radiation Monitor Calibration Laboratory of the Almirante Alvaro Alberto Power Station (CNAAA) was performed. The main purpose of this work was to update the original PSA study and to obtain the updated radiologic risk, as well as to include a human reliability analysis of the procedure of radiation monitor calibration. Some accident scenarios were incorporated for evaluating their importance for an accident that might expose a worker to gamma radiation. For obtaining the probability of occurrence of an exposition of a worker during an accident, the Bayesian approach has been used for the calculation of the irradiator failure probability, for this approach is often used when few plant information is available. For the other equipment used in the radiation monitor calibration, the exponential distribution is used to model their failure times for they are assumed to be in their useful life period. The human reliability was modeled by the THERP technique. Although more accident scenarios are considered in this work, including the contribution of human errors, a conservative approach was not used and thus a smaller radiological risk, about one order magnitude smaller was obtained.

  5. Calibration of dosimeters and survey instruments for photons at the Malaysian Secondary Standard Dosimetry Laboratory

    International Nuclear Information System (INIS)

    Radiation protection infrastructures are well established in Malaysia. The infrastructures include laws and regulations regarding the use of ionising radiations, regulatory body to enforce the regulations, the radiation protection services and radiation protection training capability. The Atomic Energy Licensing Board (AELB) is the regulatory body responsible for licensing and enforcement of the law and regulation while Malaysian Institute for Nuclear Technology Research (MINT) through its Secondary Standard Dosimetry Laboratory (SSDL) is to provide radiation protection services throughout the country. The laboratory facilitates the proper radiation calibration and verification of the instruments used for the measurement of radiation ensuring the safe use of nuclear technology. The rapid growth in the application of nuclear technology is obviously to be welcomed but there must be someway of ensuring that the safety aspects really meet the required standards. (J.P.N.)

  6. Ophthalmic applicators: An overview of calibrations following the change to SI units

    International Nuclear Information System (INIS)

    Since the NIST dose to water standard for 90Sr/90Y ophthalmic applicators was introduced, numerous sources have undergone calibration either at NIST or at the University of Wisconsin Accredited Dosimetry Calibration Laboratory (UWADCL). From 1997 to 2008, 222 of these beta-emitting sources were calibrated at the UWADCL, and prior reference source strength values were available for 149 of these sources. A survey of UWADCL ophthalmic applicator calibrations is presented here, demonstrating an average discrepancy of -19% with a standard deviation of ±16% between prior reference values and the NIST-traceable UWADCL absorbed dose to water calibrations. Values ranged from -49% to +42%.

  7. Calibration of brachytherapy sources. Guidelines on standardized procedures for the calibration of brachytherapy sources at Secondary Standard Dosimetry Laboratories (SSDLs) and hospitals

    International Nuclear Information System (INIS)

    Today, irradiation by brachytherapy is considered an essential part of the treatment for almost all the sites of cancer. With the improved localization techniques and treatment planning systems, it is now possible to have precise and reproducible dose delivery. However, the desired clinical results can only be achieved with a good clinical and dosimetric practice, i.e. with the implementation of a comprehensive quality assurance (QA) programme which includes detailed quality control procedures. As summarized in the present report, accidents in brachytherapy treatments have been caused due to the lack of traceable calibration of the sources, due to the incorrect use of quantities and units, or errors made in the dose calculation procedure. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources has established a requirement on the calibration of sources used for medical exposure. For sources used in brachytherapy treatments, a calibration traceable to a standards dosimetry laboratory is required. The present report deals with the calibration of brachytherapy sources and related quality control (QC) measurements, QC of ionization chambers and safety aspects related to the calibration procedures. It does not include safety aspects related to the clinical use of brachytherapy sources, which have been addressed in a recent IAEA publication, IAEA-TECDOC-1040, 'Design and Implementation of a Radiotherapy Programme: Clinical, Medical Physics, Radiation Protection and Safety Aspects'. The procedures recommended in this report yield traceability to internationally accepted standards. It must be realized, however, that a comprehensive QA programme for brachytherapy cannot rest on source calibration alone, but must ensure QC of all the equipment and techniques that are used for the dose delivery to the patient. The present publication incorporates the reports of several consultants meetings in the field of

    In this report, we present laboratory test simulation for directional responsivity of a global Earth albedo monitoring instrument. The sensor is to observe the Sun and the Earth, alternately, and measure their shortwave (instrument consists of a broadband scanning radiometer (energy channel instrument) and an imager (visible channel instrument) with ±2° field-of-view. In the case of the energy channel instrument, radiations arriving at the viewing ports from the Sun and the Earth are directed toward the pyroelectric detector via two spherical folding mirrors and a 3D compound parabolic concentrator (CPC). The instrument responsivity is defined by the ratio of the incident radiation input to the instrument output signal. The radiometer's relative directional responsivity needs to be characterized across the field-of-view to assist output signal calibration. For the laboratory test, the distant small source configuration consists of an off-axis collimator and the instrument with adjustable mounts. Using reconstructed 3D CPC surface, the laboratory test simulation for predicting the instrument directional responsivity was conducted by a radiative transfer computation with ray tracing technique. The technical details of the laboratory test simulation are presented together with future plan.

    Seven instrumented sensor plugs were installed on the Mars Science Laboratory heat shield in December 2008 as part of the Mars Science Laboratory Entry, Descent, and Landing Instrumentation (MEDLI) project. These sensor plugs contain four in-depth thermocouples and one Hollow aErothermal Ablation and Temperature (HEAT) sensor. The HEAT sensor follows the time progression of a 700 C isotherm through the thickness of a thermal protection system (TPS) material. The data can be used to infer char depth and, when analyzed in conjunction with the thermocouple data, the thermal gradient through the TPS material can also be determined. However, the uncertainty on the isotherm value is not well defined. To address this uncertainty, a team at NASA Ames Research Center is carrying out a HEAT sensor calibration test program. The scope of this test program is described, and initial results from experiments conducted in the laboratory to study the isotherm temperature of the HEAT sensor are presented. Data from the laboratory tests indicate an isotherm temperature of 720 C 60 C. An overview of near term arc jet testing is also given, including preliminary data from 30.48cm 30.48cm PICA panels instrumented with two MEDLI sensor plugs and tested in the NASA Ames Panel Test Facility. Forward work includes analysis of the arc jet test data, including an evaluation of the isotherm value based on the instant in time when it reaches a thermocouple depth.

  10. Dosimeter calibration facilities and methods at the Radiation Measurement Laboratory of the Centre d'etudes nucleaires, Grenoble

    International Nuclear Information System (INIS)

    At the Centre d'etudes nucleaires, Grenoble, the Radiation Measurement Laboratory, which forms part of the Environmental Protection and Research Department, serves the entire Centre for purposes of dosimetry and the calibration of dose meters. The needs of radiation protection are such that one must have facilities for checking periodically the calibration of radiation-monitoring instruments and developing special dosimetry techniques. It was thought a good idea to arrange for the dosimetry and radiation protection team to assist other groups working at the Centre - in particular, the staff of the biology and radiobiology laboratories - and also bodies outside the framework of the French Commissariat a l'energie atomique. Thus, technical collaboration has been established with, for example, Grenoble's Centre hospitalier universitaire (university clinic), which makes use of the facilities and skills available at the Radiation Measurement Laboratory for solving special dosimetry problems. With the Laboratory's facilities it is possible to calibrate dose meters for gamma, beta and neutron measurements

    Euphausiids play a key role in many marine ecosystems as a link between primary producers and top predators. Understanding their demographic (i.e. age) structure is an essential tool to assess growth and recruitment as well as to determine how changes in environmental conditions might alter their condition and distribution. Age determination of crustaceans cannot be accomplished using traditional approaches, and here we evaluate the potential for biochemical products of tissue metabolism (termed lipofuscins) to determine the demographic structure of euphausiids in field collections . Lipofuscin was extracted from krill neural tissues (eye and eye-stalk), quantified using fluorescent intensity and normalized to tissue protein content to allow comparisons across animal sizes. Multiple fluorescent components from krill were observed, with the major product having a maximum fluorescence at excitation of 355 nm and emission of 510 nm. Needed age calibration of lipofuscin accumulation in Euphausia pacifica was accomplished using known-age individuals hatched and reared in the laboratory for over one year. Lipofuscin content extracted from neural tissues of laboratory-reared animals was highly correlated with the chronological age of animals ( r=0.87). Calibrated with laboratory lipofuscin accumulation rates, field-collected sub-adult and adult E. pacifica in the Northeast Pacific were estimated to be older than 100 days and younger than 1year. Comparative data for the Antarctic krill, E. superba showed much higher lipofuscin values suggesting a much longer lifespan than the more temperate species, E. pacifica. These regional comparisons suggest that biochemical indices allow a practical approach to estimate population age structure of diverse populations, and combined with other measurements can provide estimates of vital rates (i.e. longevity, mortality, growth) for krill populations in dynamic environments.

  12. RadBallTM Technology Testing in the Savannah River Site's Health Physics Instrument Calibration Laboratory

    International Nuclear Information System (INIS)

    The UK's National Nuclear Laboratory (NNL) has developed a radiation-mapping device that can locate and quantify radioactive hazards within contaminated areas of the nuclear industry. The device, known as RadBallTM, consists of a colander-like outer collimator that houses a radiation-sensitive polymer sphere. The collimator has over two hundred small holes; thus, specific areas of the polymer sphere are exposed to radiation becoming increasingly more opaque in proportion to the absorbed dose. The polymer sphere is imaged in an optical-CT scanner that produces a high resolution 3D map of optical attenuation coefficients. Subsequent analysis of the optical attenuation data provides information on the spatial distribution of sources in a given area forming a 3D characterization of the area of interest. The RadBallTM technology has been deployed in a number of technology trials in nuclear waste reprocessing plants at Sellafield in the UK and facilities of the Savannah River National Laboratory (SRNL). This paper summarizes the tests completed at SRNL Health Physics Instrument Calibration Laboratory (HPICL).

  18. UNSAT-H infiltration model calibration at the Subsurface Disposal Area, Idaho National Engineering Laboratory

    International Nuclear Information System (INIS)

    Soil moisture monitoring data from the expanded neutron probe monitoring network located at the Subsurface Disposal Area (SDA) of the Idaho National Engineering Laboratory (INEL) were used to calibrate numerical infiltration models for 15 locations within and near the SDA. These calibrated models were then used to simulate infiltration into the SDA surficial sediments and underlying basalts for the entire operational period of the SDA (1952--1995). The purpose of performing the simulations was to obtain a time variant infiltration source term for future subsurface pathway modeling efforts as part of baseline risk assessment or performance assessments. The simulation results also provided estimates of the average recharge rate for the simulation period and insight into infiltration patterns at the SDA. These results suggest that the average aquifer recharge rate below the SDA may be at least 8 cm/yr and may be as high as 12 cm/yr. These values represent 38 and 57% of the average annual precipitation occurring at the INEL, respectively. The simulation results also indicate that the maximum evaporative depth may vary between 28 and 148 cm and is highly dependent on localized lithology within the SDA

    1990-01-01

    NASA's Dryden Flight Research Facility (Ames-Dryden), operates a diverse fleet of research aircraft which are heavily instrumented to provide both real time data for in-flight monitoring and recorded data for postflight analysis. Ames-Dryden's existing automated calibration (AUTOCAL) laboratory is a computerized facility which tests aircraft sensors to certify accuracy for anticipated harsh flight environments. Recently, a major AUTOCAL lab upgrade was initiated; the goal of this modernization is to enhance productivity and improve configuration management for both software and test data. The new system will have multiple testing stations employing distributed processing linked by a local area network to a centralized database. The baseline requirements for the new AUTOCAL lab and the design approach being taken for its mechanization are described.

    2016-04-01

    Nowadays, numerical simulations are indispensable allies for the researchers to reproduce phenomena such as earth-flows, debris-flows and mudflows. One of the most difficult and problematic phases is about the choice and the calibration of the parameters to be included in the model at the real scale. Surely, it can be useful to start from laboratory experiment that simplify as much as possible the case study with the aim of reducing uncertainties related to the trigger and the propagation of a real flow. In this way, geometry of the problem, identification of the triggering mass, are well known and constrained in the experimental tests as in the numerical simulations and the focus of the study may be moved to the material parameters. This article wants to analyze the behavior of different mixtures of water and kaolin, which flow in a laboratory channel. A 10 dm3 prismatic container that discharges the material into a channel 2m long and 0.16 m wide composes the simple experimental apparatus. The chute base was roughened by glued sand and inclined with a 21° angle. Initially, we evaluated the lengths of run-out, the spread and shape of the deposit for five different mixtures. A huge quantity of information were obtained by 3 laser sensors attached to the channel and by photogrammetry, that gives out a 3D model of the deposit shape at the end of the flow. Subsequently, we reproduced these physical phenomena by using the numerical model Geoflow-SPH (Pastor et al., 2008; 2014) , governed by a Bingham rheological law (O'Brien & Julien, 1988), and we calibrated the different tests by back-analysis to assess optimum parameters. The final goal was the comprehension of the relationship that characterizes the parameters with the variation of the kaolin content in the mixtures.

  1. In-situ calibration of criticality monitor in radioactive laboratories by shooting device technique

    International Nuclear Information System (INIS)

    Criticality safety is of utmost importance, where isotopes of fissile radioactive material (Pu, U, etc) handled in large quantities in different fuel fabrication facilities. In general, apart from mass control, geometry control in handling radioactive materials, administrative control is a necessity for smooth operation of the facilities. The point of concern in radioactive laboratories is 'criticality' situation. The criticality situation is associated with the burst of neutron and gamma radiation, The detector used to assess such an incident is either calibrated using neutron detection or gamma detection technique simulating the burst of neutron or gamma ray. These detectors should be calibrated and kept up to date to avoid such an incident. A burst of 1015 fission will deliver a prompt gamma dose of 2.5 mSv at a distance of 30 feet (9.144 m). Assuming, the dose delivered in 100 msec, the dose rate will be 102Sv/h, which shall involve in a change of six to seven decade from background in 100 msec. Thus, there are two methods for which a criticality monitor has to be calibrated: i) Steady state 1.3R/h ii) Integrated dose of 2.6 mrem in 200 msec. A source shooting device was designed which uses a cobalt (60Co) one Curie (Ci) source for calibration as per integrated dose limit, The total time of flight shall be ∼ 400 msec for the source with an adjustable average velocity of 8 to 10 m/sec. The velocity is achieved using pneumatic pressure, filled inside a container. The velocity can be varied depending upon the air pressure inside the cylinder. The system is designed with an impact absorber at the end, to reduce the force during impact which prevents it from bulging under successive flights. A reverse air purging system is designed to get cushioning effect to the source at the end of flight to avoid the flaring of the source. The device is tested using dummy source containers for structural integrity and leak tightness. The main feature of this system is its

  2. Training Accreditation Program

    International Nuclear Information System (INIS)

    The Training Accreditation Program establishes the objectives and criteria against which DOE nuclear facility training is evaluated to determine its readiness for accreditation. Training programs are evaluated against the accreditation objectives and criteria by facility personnel during the initial self-evaluation process. From this self-evaluation, action plans are made by the contractor to address the scope of work necessary in order to upgrade any deficiencies noted. This scope of work must be formally documented in the Training Program Accreditation Plan. When reviewed and approved by the responsible Head of the Field Organization and cognizant Program Secretarial Office, EH-1 concurrence is obtained. This plan then becomes the document which guides accreditation efforts for the contractor

    The quality control section of Plutonium Fuel Development Center (PFDC) of Japan Atomic Energy Agency has been analyzing isotopic compositions by Mass Spectrometry as well as content by Isotope Dilution Mass Spectrometry (IDMS) of plutonium and uranium in nuclear materials. Along with establishing and managing the quality assurance system, ensuring the reliability of the analysis data is important. PFDC has been establishing the quality management system with ISO9001. ISO9001 consists of management requirements for quality system of organizations. While ISO/IEC 17025 consists of technical requirements for the competence of testing and calibration laboratories in addition to the management requirements. The quality control section addressed technical improvement to improve further reliability of analysis quality and we have accredited for ISO/IEC 17025 of isotopic compositions and content of plutonium and uranium in nuclear materials in March 2010. In this presentation, we report our approaches to the ISO/IEC 17025 accreditation and operation status. (author)

  5. Accreditation standards for undergraduate forensic science programs

    Miller, Marilyn Tebbs

    Undergraduate forensic science programs are experiencing unprecedented growth in numbers of programs offered and, as a result, student enrollments are increasing. Currently, however, these programs are not subject to professional specialized accreditation. This study sought to identify desirable student outcome measures for undergraduate forensic science programs that should be incorporated into such an accreditation process. To determine desirable student outcomes, three types of data were collected and analyzed. All the existing undergraduate forensic science programs in the United States were examined with regard to the input measures of degree requirements and curriculum content, and for the output measures of mission statements and student competencies. Accreditation procedures and guidelines for three other science-based disciplines, computer science, dietetics, and nursing, were examined to provide guidance on accreditation processes for forensic science education programs. Expert opinion on outcomes for program graduates was solicited from the major stakeholders of undergraduate forensic science programs-forensic science educators, crime laboratory directors, and recent graduates. Opinions were gathered by using a structured Internet-based survey; the total response rate was 48%. Examination of the existing undergraduate forensic science programs revealed that these programs do not use outcome measures. Of the accreditation processes for other science-based programs, nursing education provided the best model for forensic science education, due primarily to the balance between the generality and the specificity of the outcome measures. From the analysis of the questionnaire data, preliminary student outcomes, both general and discipline-specific, suitable for use in the accreditation of undergraduate forensic science programs were determined. The preliminary results were reviewed by a panel of experts and, based on their recommendations, the outcomes

  6. US accreditation programmes for personal radiation dosimetry

    International Nuclear Information System (INIS)

    In order to verify an acceptable level of safety in the workplace, it is necessary to measure the quantity of ionising radiation to which radiation workers could be, or actually are, exposed. At present, there are organisations capable of providing measurement results with good accuracy and precision. These organisations may provide personal dosimetry services to their own facilities, or to others on a contractual basis. They generally have high quality equipment and well trained personnel. However, in today's climate, it is important to demonstrate and document that these systems and services to others meet national standards of quality. In order to provide a higher level of confidence in the results generated by organisations that provide personal dosimetry services in the US, two accreditation programmes have been established. They are the Department of Energy Laboratory Accreditation Program (DOELAP) and the National Voluntary Laboratory Accreditation Program (NVLAP). These two programmes will be described and results will be given, along with plans for future development. (author)

  7. Non-matrix Matched Glass Disk Calibration Standards Improve XRF Micronutrient Analysis of Wheat Grain across Five Laboratories in India.

    Guild, Georgia E; Stangoulis, James C R

    2016-01-01

    Within the HarvestPlus program there are many collaborators currently using X-Ray Fluorescence (XRF) spectroscopy to measure Fe and Zn in their target crops. In India, five HarvestPlus wheat collaborators have laboratories that conduct this analysis and their throughput has increased significantly. The benefits of using XRF are its ease of use, minimal sample preparation and high throughput analysis. The lack of commercially available calibration standards has led to a need for alternative calibration arrangements for many of the instruments. Consequently, the majority of instruments have either been installed with an electronic transfer of an original grain calibration set developed by a preferred lab, or a locally supplied calibration. Unfortunately, neither of these methods has been entirely successful. The electronic transfer is unable to account for small variations between the instruments, whereas the use of a locally provided calibration set is heavily reliant on the accuracy of the reference analysis method, which is particularly difficult to achieve when analyzing low levels of micronutrient. Consequently, we have developed a calibration method that uses non-matrix matched glass disks. Here we present the validation of this method and show this calibration approach can improve the reproducibility and accuracy of whole grain wheat analysis on 5 different XRF instruments across the HarvestPlus breeding program.

  9. Comparison of Continuous Wave CO2 Doppler Lidar Calibration Using Earth Surface Targets in Laboratory and Airborne Measurements

    Science.gov (United States)

    Jarzembski, Maurice A.; Srivastava, Vandana

    1999-01-01

    Routine backscatter, beta, measurements by an airborne or space-based lidar from designated earth surfaces with known and fairly uniform beta properties can potentially offer lidar calibration opportunities. This can in turn be used to obtain accurate atmospheric aerosol and cloud beta measurements on large spatial scales. This is important because achieving a precise calibration factor for large pulsed lidars then need not rest solely on using a standard hard target procedure. Furthermore, calibration from designated earth surfaces would provide an inflight performance evaluation of the lidar. Hence, with active remote sensing using lasers with high resolution data, calibration of a space-based lidar using earth's surfaces will be extremely useful. The calibration methodology using the earth's surface initially requires measuring beta of various earth surfaces simulated in the laboratory using a focused continuous wave (CW) CO2 Doppler lidar and then use these beta measurements as standards for the earth surface signal from airborne or space-based lidars. Since beta from the earth's surface may be retrieved at different angles of incidence, beta would also need to be measured at various angles of incidences of the different surfaces. In general, Earth-surface reflectance measurements have been made in the infrared, but the use of lidars to characterize them and in turn use of the Earth's surface to calibrate lidars has not been made. The feasibility of this calibration methodology is demonstrated through a comparison of these laboratory measurements with actual earth surface beta retrieved from the same lidar during the NASA/Multi-center Airborne Coherent Atmospheric Wind Sensor (MACAWS) mission on NASA's DC8 aircraft from 13 - 26 September, 1995.

This was compared with the actual lidar efficiency

    Voluntary accreditation of cells, tissues, and cellular and tissue-based products intended for human transplantation is an important mechanism for improving quality in cellular therapy. The Foundation for the Accreditation of Cellular Therapy (FACT) has developed and implemented programs of voluntary inspection and accreditation for hematopoietic cellular therapy, and for cord blood banking. These programs are based on the standards of the clinical and laboratory professionals of the American Society of Blood and Marrow Transplantation (ASBMT), the International Society for Cellular Therapy (ISCT), and NETCORD. FACT has collaborated with European colleagues in the development of the Joint Accreditation Committee in Europe (jACIE). FACT has published standards documents, a guidance manual, accreditation checklists, and inspection documents; and has trained as inspectors over 300 professionals active in the field. All inspectors have a minimum of 5 years' experience in the area they inspect. Since the incorporation of FACT in 1996, 215 hematopoietic progenitor cell facilities have applied for FACT accreditation. Of these facilities, 113 are fully accredited; the others are in the process of document submission or inspection. Significant opportunities and challenges exist for FACT in the future, including keeping standards and guidance materials current and relevant, recruiting and retaining expert inspectors, and establishing collaborations to develop standards and accreditation systems for new cellular products. The continuing dialogue with the Food and Drug Administration (FDA) is also important to ensure that they are aware of the accomplishments of voluntary accreditation, and keep FACT membership alerted to FDA intentions for the future. Other potential avenues of communication and cooperation with FDA and other regulatory agencies are being investigated and evaluated. PMID:12944235

    The Accreditation Council for Graduate Medical Education has implemented a new accreditation system for graduate medical education in the United States. This system, called the Next Accreditation System, focuses on more continuous monitoring of the outcomes of residency training, and for high-quality programs, less on the detailed processes of that training. This allows programs to innovate to best meet the needs of their trainees and communities. This new system also reviews the clinical learning environment at each institution sponsoring graduate medical education, focusing on professionalism, trainee supervision, duty hour and fatigue management, care transitions, and integration of residents into patient safety and health care quality. This Next Accreditation System is too new to fully assess its outcomes in better preparing residents for medical practice. Assessments of its early implementation, however, suggest we can expect such outcomes in the near future. PMID:26859375

    International Nuclear Information System (INIS)

    Conformity Assessment Bodies (laboratories , certification and inspection bodies, etc ) assess conformity of products and services to requirements , usually relating to quality and safety. For their activities to provide due confidence both in national and international markets these bodies must demonstrate to have the relevant technical competence and to perform according to international standards. This confidence is based on the assessments conducted in different countries by the accreditation body in Spain ENAC. Using accredited conformity assessment bodies bodies: risks are minimized; customer confidence is increased; acceptance in foreign countries is enhanced; self-regulation is promoted. (Author)

    A multiplex assay with 49 autosomal single nucleotide polymorphisms (SNPs) developed for human identification was validated for forensic genetic casework and accredited according to the ISO 17025 standard. The multiplex assay was based on the SNPforID 52plex SNP assay [J.J. Sanchez, C. Phillips, C...... amplified in one PCR reaction. The SNPs were analysed by single base extension (SBE) and capillary electrophoresis. Twenty-three of the original SBE primers were altered to improve the overall robustness of the assay and to simplify the analysis of the SBE results. A total of 216 samples from 50 paternity...... cases and 33 twin cases were typed at least twice for the 49 SNPs. All electropherograms were analysed independently by two expert analysts prior to approval. Based on these results, detailed guidelines for analysis of the SBE products were developed. With these guidelines, the peak height ratio of a...

    Spacecraft images of asteroids show evidence of low-gravity granular flows. Interpretation of these flows requires numerical modeling, which in turn requires code validation at laboratory scales. We have implemented a soft-sphere discrete element method (SSDEM) for modeling granular flows in our numerical code (Schwartz et al. 2012, Granular Matter 14, 363). Here we present results from a study to calibrate our code against controlled landslide experiments in order to determine the SSDEM parameters that best match real materials, to see how changes in those parameters affect the flow, and to mimic effects such as those due to irregular particle shapes. The apparatus, designed at University of Braunschweig, is a 0.6 × 0.8 m enclosed bed with a surface comprised of 10 mm diameter glass spheres glued into precisely drilled holes in a metal plate. The exact positions and depths of each of these glued spheres are input to the simulations. The experiments consist of filling the apparatus with loose glass beads (also 10 mm diameter) up to a set depth then gradually tilting the bed to note the angle of landslide initiation and the characteristics of the resulting flow. We reproduce this procedure in simulations, which we find are quite sensitive to the adopted SSDEM parameters, e.g., rolling friction and tangential damping delay landslide onset, while higher particle elasticity gives rise to faster, shorter-duration landslides. Preliminary results show a best match to the experiments (landslide initiation around 25 degrees) when adopting low static friction and no rolling friction in the simulations, but more experiments are in process. In future work, we will perform simulations in low-gravity environments representative of asteroid surfaces. This work is supported in part by grant NNX08AM39G from the NASA Office of Space Science. This study resulted from International Team collaboration #202 sponsored by ISSI in Switzerland.

  18. Field and laboratory calibration of neutron probes for soil moisture measurements on a deep loess chernozem soil

    International Nuclear Information System (INIS)

    In the case of a varying profile structure it is necessary to use different calibration curves and adequate correction factors, respectively. The bulk density of the soil had the greatest influence on the calibration. An increase in bulk density by 0.2 g/cm3 at a clay content of 18% resulted in an apparent increase in the values of moisture measurements by 1.5 to 2.0% of the volume of water. In naturally stratified soil the humus content of the chernozem horizon, being 3% higher than that of the underlying loess horizon, was found to influence the measuring results obtained by the probe. The calibration curves determined for chernozem and loess horizons in the laboratory agreed well with those obtained in the field. The measured values read from the probe and the gravimetrically determined values of the soil moisture were of great significance in all measured depths of the profile. (author)

    French medical laboratories must be accredited before November 2016 according to NF/EN/ISO 15189 standard. However, technical accreditation guidelines cannot be applied literally for the determination of specific IgE for several reasons: more than 600 allergen tests, lack of international gold standard, limited external quality controls. Furthermore, the technique for determination of specific IgE is CE DM-IVD marked, common to all specificities, automatised, standardized according to a single calibration curve. Thus, we propose an efficient but reasonable solution conform to the idea of the accreditation by validating the process. We recommend: a flexible extend type A; choice of only one representative allergen (Dermatophagoides pteronyssinus) for repeatability and precision (20 tests, 2 levels 0.5-1 and 8-12 kUA/L) performed on patients sera, reproducibility (30 consecutive determinations using an Internal Quality Control/IQC), accuracy (IQC and rare External Quality Controls) compared with peers. Sensitivity, specificity, dynamic range, detection threshold are determinated by the provider. Linearity may be checked if the laboratory practices sample dilution for values higher than the upper limit guaranteed by the provider. In the absence of international gold standard, the uncertainty is not measurable. In case of change of instrument, the results obtained by the systems must be compared through 35 tests of different specificities distributed across the range of calibration and including 5 values close to the detection limit. This methodology allows a scientifically effective verification, technically and financially reasonable, to ensure the excellence of the performance of the laboratory with regard to peers and users (allergologists and patients).

    Recently, photon-counting detectors capable of resolving incident x-ray photon energies have been considered for use in spectral x-ray imaging applications. For reliable use of energy-resolved photon-counting detectors (ERPCDs), energy calibration is an essential procedure prior to their use because variations in responses from each pixel of the ERPCD for incident photons, even at the same energy, are inevitable. Energy calibration can be performed using a variety of methods. In all of these methods, the photon spectra with well-defined peak energies are recorded. Every pixel should be calibrated on its own. In this study, we suggest the use of a conventional polychromatic x-ray source (that is typically used in laboratories) for energy calibration. The energy calibration procedure mainly includes the determination of the peak energies in the spectra, flood-field irradiation, determination of peak channels, and determination of calibration curves (i.e., the slopes and intercepts of linear polynomials). We applied a calibration algorithm to a CdTe ERPCD comprised of 128×128 pixels with a pitch of 0.35 mm using highly attenuated polychromatic x-ray beams to reduce the pulse pile-up effect, and to obtain a narrow-shaped spectrum due to beam hardening. The averaged relative error in calibration curves obtained from 16,384 pixels was about 0.56% for 59.6 keV photons from an Americium radioisotope. This pixel-by-pixel energy calibration enhanced the signal- and contrast-to-noise ratios in images, respectively, by a factor of ∼5 and 3 due to improvement in image homogeneity, compared to those obtained without energy calibration. One secondary finding of this study was that the x-ray photon spectra obtained using a common algorithm for computing x-ray spectra reasonably described the peaks in the measured spectra, which implies easier peak detection without the direct measurement of spectra using a separate spectrometer. The proposed method will be a useful alternative

    Besides the rapid development of healing procedures and healthcare, efficiency of care, institutional performance and safe treatment are receiving more and more attention in the 21st century. Accreditation, a scientifically proven tool for improving patient safety, has been used effectively in healthcare for nearly a hundred years, but only started to spread worldwide since the 1990s. The support and active participation of medical staff are determining factors in operating and getting accross the nationally developed, upcoming Hungarian accreditation system. However, this active assistance cannot be expected without the participants' understanding of the basic goals and features of the system. The presence of the ISO certification in Hungary, well-known by healthcare professionals, further complicates the understanding and orientation among quality management and improvement systems. This paper aims to provide an overview of the history, goals, function and importance of healthcare accreditation, and its similarities and differences regarding ISO certification. PMID:26772826

    The international evaluation of the Centre for Metrology and Accreditation (MIKES) is part of the process in which all relevant industrial and technology policy measures and organizations under the auspices of the Ministry of Trade and Industry (MTI) are being evaluated with the aim of improving their effectiveness. The overall conclusion of the evaluation is that MIKES is serving the country well. An effective national measurement system (FINMET) is being maintained which provides a wide range of calibration services covering most of the nation`s needs. The accreditation service (FINAS) is now well established, is operating effectively, and has good prospects for growth. The evaluators present, however, a number of proposals (including 33 specific recommendations) where they feel that the metrology and accreditation arrangements could be better-suited to meet future national and international challenges. According to the recommendations the Finnish quality policy framework should be developed in a consistent way. There is a need of a comprehensive governmental quality policy statement upon which the inter-ministry coordination and harmonization of various conformity assessment activities can be based. MIKES should retain its current status as an agency within MTI. The national measurement system should be more centralised and a new purpose-built national standards laboratory should be procured. The responsibility for legal metrology should be transferred to MIKES. The terms of reference and membership of Advisory Committee for Metrology, as well as the Advisory Committee for Accreditation should be revised to ensure wider representation of all relevant, and especially industrial interests

  7. The method validation step of biological dosimetry accreditation process

    International Nuclear Information System (INIS)

    One of the missions of the Laboratory of Biological Dosimetry (L.D.B.) of the Institute for Radiation and Nuclear Safety (I.R.S.N.) is to assess the radiological dose after an accidental overexposure suspicion to ionising radiation, by using radio-induced changes of some biological parameters. The 'gold standard' is the yield of dicentrics observed in patients lymphocytes, and this yield is converted in dose using dose effect relationships. This method is complementary to clinical and physical dosimetry, for medical team in charge of the patients. To obtain a formal recognition of its operational activity, the laboratory decided three years ago, to require an accreditation, by following the recommendations of both 17025 General Requirements for the Competence of Testing and Calibration Laboratories and 19238 Performance criteria for service laboratories performing biological dosimetry by cyto-genetics. Diagnostics, risks analysis were realized to control the whole analysis process leading to documents writing. Purchases, personnel department, vocational training were also included in the quality system. Audits were very helpful to improve the quality system. One specificity of this technique is that it is not normalized therefore apart from quality management aspects, several technical points needed some validations. An inventory of potentially influent factors was carried out. To estimate their real effect on the yield of dicentrics, a Placket-Burman experimental design was conducted. The effect of seven parameters was tested: the BUdr (bromodeoxyuridine), PHA (phytohemagglutinin) and colcemid concentration, the culture duration, the incubator temperature, the blood volume and the medium volume. The chosen values were calculated according to the uncertainties on the way they were measured i.e. pipettes, thermometers, test tubes. None of the factors has a significant impact on the yield of dicentrics. Therefore the uncertainty linked to their use was considered as

  8. Characterization of a 137Cs standard source for calibration purposes ar CRCN-NE

    International Nuclear Information System (INIS)

    Radiation protection monitoring instruments should be calibrated by accredited calibration laboratories. To offer calibration services, a laboratory must accomplish all requirements established by the national regulatory agency. The Calibration Service of the Centro Regional de Ciencias Nucleares (CRCN-NE), Comissao Nacional de Energia Nuclear, Recife, Brazil, is trying to achieve this accreditation. In the present work, a 137Cs standard source was characterized following the national and international recommendations and the results are presented. This source is a commercially available single source irradiator model 28-8A, manufactured by JLShepherd and Associates, with initial activity of 444 GBq (05/13/03). To provide different air kerma rates, as required for the calibration of portable radiation monitors, this irradiator have a set of four lead attenuators with different thickness, providing attenuation factors equal to 2, 4, 10 and 100 times (nominally). The performed tests included: size and uniformity of the radiation standard field at calibration reference position, variation of the air kerma rate for different lead attenuators, determination of attenuation factors for each lead attenuator configuration, and determination of the radiation scattering at the calibration reference position. The results showed the usefulness of the 137Cs standard source for the calibration of radiation protection monitoring detectors. (author)

    2012-01-01

    The measurement goals of the Sample Analysis at Mars (SAM) instrument suite on the "Curiosity" Rover of the Mars Science Laboratory (MSL) include chemical and isotopic analysis of organic and inorganic volatiles for both atmospheric and solid samples [1,2]. SAM directly supports the ambitious goals of the MSL mission to provide a quantitative assessment of habitability and preservation in Gale crater by means of a range of chemical and geological measurements [3]. The SAM FM combined calibration and environmental testing took place primarily in 2010 with a limited set of tests implemented after integration into the rover in January 2011. The scope of SAM FM testing was limited both to preserve SAM consumables such as life time of its electromechanical elements and to minimize the level of terrestrial contamination in the SAM instrument. A more comprehensive calibration of a SAM-like suite of instruments will be implemented in 2012 with calibration runs planned for the SAM testbed. The SAM Testbed is nearly identical to the SAM FM and operates in a ambient pressure chamber. The SAM Instrument Suite: SAM's instruments are a Quadrupole Mass Spectrometer (QMS), a 6-column Gas Chromatograph (GC), and a 2-channel Tunable Laser Spectrometer (TLS). Gas Chromatography Mass Spectrometry is designed for identification of even trace organic compounds. The TLS [5] secures the C, H, and O isotopic composition in carbon dioxide, water, and methane. Sieved materials are delivered from the MSL sample acquisition and processing system to one of68 cups of the Sample Manipulation System (SMS). 59 of these cups are fabricated from inert quartz. After sample delivery, a cup is inserted into one of 2 ovens for evolved gas analysis (EGA ambient to >9500C) by the QMS and TLS. A portion of the gas released can be trapped and subsequently analyzed by GCMS. Nine sealed cups contain liquid solvents and chemical derivatization or thermochemolysis agents to extract and transform polar molecules

    2012-01-01

    The authors review widely accepted criteria for program accreditation and compare gerontology with well-established accredited fields including clinical psychology and social work. At present gerontology lacks many necessary elements for credible professional accreditation, including defined scope of practice, applied curriculum, faculty with applied professional credentials, and resources necessary to support professional credentialing review. Accreditation with weak requirements will be dismissed as "vanity" accreditation, and strict requirements will be impossible for many resource-poor programs to achieve, putting unaccredited programs at increased risk for elimination. Accreditation may be appropriate in the future, but it should be limited to professional or applied gerontology, perhaps for programs conferring bachelor's or master's degrees. Options other than accreditation to enhance professional skills and employability of gerontology graduates are discussed. PMID:22289064

    The use of linear accelerators in radiotherapy is of great importance in Medicine, and according to international recommendations the electron beam dosimetry has to be performed using plane-parallel ionization chambers, previously calibrated in standard gamma radiation fields at accredited laboratories. In this work, calibration methods of plane-parallel ionization chambers used in dosimetry procedures of high energy electron beams of clinical accelerators were presented, tested and intercompared. The experiments were carried out using gamma radiation beams of 60 Co at the Calibration Laboratory of Clinical Dosemeters at IPEN and electron beams od 4 to 16 MeV at the Radiotherapy Department of Hospital Israelita Albert Einstein, Sao Paulo. A method was chosen to be established at IPEN. Proposals of the calibration procedure, calibration certificate and data sheets are presented. (author)

The national and the international intercomparisons were emphasised. The results for graphite wall chambers were compared, observing a maximum variation of about 0,6%. In the case of Delrin (TK01) wall chambers, the maximum variation was 1,7%. The results of post intercomparisons with thermoluminescent dosemeters have presented derivations lesser than 1%, securing the standards consistence at LNMRI with the international metrological system.

  16. Strategy on quality assurance in radiation fields and calibration techniques at FRS of JAEA

    International Nuclear Information System (INIS)

    The FRS, Facility of Radiation Standards, of JAEA has been developing and supplying the fields of X-, gamma-, beta-rays and neutrons for calibrating the radiation measuring devices used for radiation protection monitoring since 1980. Much effort has been devoted in recent years toward the development of the neutron and gamma-ray fields using a 4 MV Van de Graaff accelerator. In November 2006, we just started to open the FRS radiation reference fields to national laboratories, private industry and academia. Almost the fields are traceable to national standards, but a laboratory quality assurance is not yet realized. We plan to obtain the calibration laboratory accreditation of JCSS, Japan Calibration Service System, which is based on ISO-17025. Furthermore, the quality assurance is planed to be extended to the international credibility in the future, and we hope to play a leading role in the calibration facilities in Asia. (author)

  17. Mammography accreditation program

    1993-12-31

    In the mid-1980`s, the movement toward the use of dedicated mammography equipment provided significant improvement in breast cancer detection. However, several studies demonstrated that this change was not sufficient to ensure optimal image quality at a low radiation dose. In particular, the 1985 Nationwide Evaluation of X-ray Trends identified the wide variations in image quality and radiation dose, even from dedicated units. During this time period, the American Cancer Society (ACS) launched its Breast Cancer Awareness Screening Campaign. However, there were concerns about the ability of radiology to respond to the increased demand for optimal screening examinations that would result from the ACS program. To respond to these concerns, the ACS and the American College of Radiology (ACR) established a joint committee on mammography screening in 1986. After much discussion, it was decided to use the ACR Diagnostic Practice Accreditation Program as a model for the development of a mammography accreditation program. However, some constraints were required in order to make the program meet the needs of the ACS. This voluntary, peer review program had to be timely and cost effective. It was determined that the best way to address these needs would be to conduct the program by mail. Finally, by placing emphasis on the educational nature of the program, it would provide an even greater opportunity for improving mammographic quality. The result of this effort was that, almost six years ago, in May 1987, the pilot study for the ACR Mammography Accreditation Program (MAP) began, and in August of that year, the first applications were received. In November 1987, the first 3-year accreditation certificates were awarded.

In particular, the 1985 Nationwide Evaluation of X-ray Trends identified the wide variations in image quality and radiation dose, even from dedicated units. During this time period, the American Cancer Society (ACS) launched its Breast Cancer Awareness Screening Campaign. However, there were concerns about the ability of radiology to respond to the increased demand for optimal screening examinations that would result from the ACS program. To respond to these concerns, the ACS and the American College of Radiology (ACR) established a joint committee on mammography screening in 1986. After much discussion, it was decided to use the ACR Diagnostic Practice Accreditation Program as a model for the development of a mammography accreditation program. However, some constraints were required in order to make the program meet the needs of the ACS. This voluntary, peer review program had to be timely and cost effective. It was determined that the best way to address these needs would be to conduct the program by mail. Finally, by placing emphasis on the educational nature of the program, it would provide an even greater opportunity for improving mammographic quality. The result of this effort was that, almost six years ago, in May 1987, the pilot study for the ACR Mammography Accreditation Program (MAP) began, and in August of that year, the first applications were received. In November 1987, the first 3-year accreditation certificates were awarded

  20. Calibration of photon and beta ray sources used in brachytherapy. Guidelines on standardized procedures at Secondary Standards Dosimetry Laboratories

    International Nuclear Information System (INIS)

    It has generally been recognized that international harmonization in radiotherapy dosimetry is essential. Consequently, the IAEA has given much effort to this, for example by publishing a number of reports in the Technical Reports Series (TRS) for external beam dosimetry, most notably TRS-277 and more recently TRS-398. Both of these reports describe in detail the steps to be taken for absorbed dose determination in water and they are often referred to as 'dosimetry protocols'. Similar to TRS-277, it is expected that TRS-398 will be adopted or used as a model by a large number of countries as their national protocol. In 1996, the IAEA established a calibration service for low dose rate (LDR) 137 Cs brachytherapy sources, which is the most widely used source for treatment of gynecological cancer. To further enhance harmonization in brachytherapy dosimetry, the IAEA published in 1999 IAEA-TECDOC-1079 entitled 'Calibration of Brachytherapy Sources. Guidelines on Standardized Procedures for the Calibration of Brachytherapy Sources at Secondary Standard Dosimetry Laboratories (SSDLs) and Hospitals'. The report was well received and was distributed in a large number of copies to the members of the IAEA/WHO network of SSDLs and to medical physicists working with brachytherapy. The present report is an update of the aforementioned TECDOC. Whereas TECDOC-1079 described methods for calibrating brachytherapy sources with photon energies at or above those of 192Ir, the current report has a wider scope in that it deals with standardization of calibration of all the most commonly used brachytherapy sources, including both photon and beta emitting sources. The latter sources have been in use for a few decades already, but their calibration methods have been unclear. Methods are also described for calibrating sources used in the rapidly growing field of cardiovascular angioplasty. In this application, irradiation of the vessel wall is done in an attempt to prevent restenosis after

    The Calibration Laboratory of Instruments of Instituto de Pesquisas Energeticas e Nucleares offers calibration services of radiation detectors used in radioprotection, diagnostic radiology and radiotherapy, for IPEN and for external facilities (public and private). One part of its facilities is located in the main building, along with other laboratories and study rooms, and another part in an isolated building called Bunker. For the optimization, modernization and specially the safety, the laboratories in the main building shall be transferred to an isolated place. In this work, a project of an integrated laboratory for calibration of instruments was developed, and it will be an expansion of the current Calibration Laboratory of Instruments of IPEN. Therefore, a series of radiometric monitoring of the chosen localization of the future laboratory was realized, and all staff needs (dimensions and disposition of the study rooms and laboratories) were defined. In this project, the laboratories with X ray equipment, alpha and beta radiation sources were located at an isolated part of the building, and the wall shielding was determined, depending on the use of each laboratory.

    The Plan of Radiological Protection licensed by the National Nuclear Energy Commission - CNEN in Brazil includes the risks of assessment of internal and external exposure by implementing a program of individual monitoring which is responsible of controlling exposures and ensuring the maintenance of radiation safety. The Laboratory of Internal Dosimetry of the Center for Development of Nuclear Technology - LID/CDTN is responsible for routine monitoring of internal contamination of the Individuals Occupationally Exposed (IOEs). These are, the IOEs involved in handling {sup 18}F produced by the Unit for Research and Production of Radiopharmaceuticals sources; as well a monitoring of the entire body of workers from the Research Reactor TRIGA IPR-R1/CDTN or whenever there is any risk of accidental incorporation. The determination of photon emitting radionuclides from the human body requires calibration techniques of the counting geometries, in order to obtain a curve of efficiency. The calibration process normally makes use of physical phantoms containing certified activities of the radionuclides of interest. The objective of this project is the calibration of the WBC facility of the LID/CDTN using the BOMAB physical phantom and Monte Carlo simulations. Three steps were needed to complete the calibration process. First, the BOMAB was filled with a KCl solution and several measurements of the gamma ray energy (1.46 MeV) emitted by {sup 40}K were done. Second, simulations using MCNPX code were performed to calculate the counting efficiency (Ce) for the BOMAB model phantom and compared with the measurements Ce results. Third and last step, the modeled BOMAB phantom was used to calculate the Ce covering the energy range of interest. The results showed a good agreement and are within the expected ratio between the measured and simulated results. (Author)

    International Nuclear Information System (INIS)

    The ISO/EEC Guide 25: 1993 Standard General requirements for the competence of calibration and testing laboratories. Is published in Brazil by Brazilian Association for Technical Standards (ABNT) as ABNT ISO/DEC GUIA 25 and establishes general requirements a laboratory must demonstrate to meet, in order to be recognized as having technical competence (accreditation) to carry out specifics calibration or testing. Therefore, the accredited laboratory starts, respectively, taking part from the Brazilian Calibration Network (RBC) or from the Brazilian Testing Laboratories Network (RBLE) . The Environmental Radioanalysis Division (DIAMB) from Environmental Radiological Protection Department (DEPRA) from Institute of Radiation Protection and Dosimetry (IRD) from Brazilian National Nuclear Energy Commission (CNEN) is a laboratory responsible for analyzing radionuclides deriving for the samples from DEPRA's Surveillance Program, research and servings, due to an eventual radionuclide contamination in environment, foods and others raw materials for human consumption; including for importation and exportation products certification purposes. For all these reasons, DIAMB needs its formal recognition for carrying out radionuclides analysis in environmental samples. This work aims to provide a methodology in order to guide a laboratory which has the intention to implement a accreditation process. It also describes policies to meet the requirements related to the Standard, guidance needed to specification of some steps and also comments some points from the Standard in order to become easier all the accreditation process comprehension.

  7. Calibration techniques and error analysis for phoswich counting of actinide nuclides at Oak Ridge National Laboratory

    International Nuclear Information System (INIS)

    One of the most difficult and demanding areas of low-level counting is the detection of actinides in vivo. In the case of inhalation of these nuclides, it is common practice at many installations to determine the resulting lung burden by external counting of low-intensity L X-rays from the daughter nucleus with either a phoswich detector or a proportional counter. Calibration techniques using these detectors are examined and possible uncertainties in the determination of lung burden by using standard techniques are discussed. The use of phoswich detectors is discussed in detail

    2006-01-01

    Although the basic principle of reciprocity calibration of microphones in a free field is simple, the practical problems are complicated due to the low signal-to-noise ratio and the influence of cross talk and reflections from the surroundings. The influence of uncorrelated noise can be reduced by...... FFT-based time-selective technique. The complex electrical transfer impedance is measured in linear frequency steps from a few kHz to about three times the resonance frequency of the microphones. The missing values at low frequencies are estimated from a detailed knowledge of the pressure...... sensitivities. Next an inverse FFT is applied and a time window around the main signal is used to eliminate cross talk and reflections. Finally, the signal is transformed back to the frequency domain and the free field sensitivities calculated. The standard procedure at DPLA involves measurements at four...

    2007-07-01

    The measurement of the neutron electric form factor, GEn, will allow us to solve indirectly for the quark charge distribution inside of the neutron. With the equipment at Jefferson Lab we have measured GEn at four momentum transfer values of Q**2 at 1.3, 2.4 and 3.4 (GeV/c)**2 using a polarized electron beam and polarized Helium target. The scattered electrons off of the Helium target are detected in the BigBite spectrometer and the recoiling neutrons from the Helium are detected in the Neutron Arm, which is composed of an array of scintillators. The main focus of this thesis will be devoted to the geometry, timing and energy calibrations of the Neutron Arm.

  11. Estimation of absorbed dose in clinical radiotherapy linear accelerator beams: effect of ion chamber calibration and long-term stability

    International Nuclear Information System (INIS)

    The measured dose in water at reference point in phantom is a primary parameter for planning the treatment monitor units (MU); both in conventional and intensity modulated/image guided treatments. Traceability of dose accuracy therefore still depends mainly on the calibration factor of the ion chamber/dosimeter provided by the accredited Secondary Standard Dosimetry Laboratories (SSDLs), under International Atomic Energy Agency (IAEA) network of laboratories. The data related to Nd,water calibrations, thermoluminescent dosimetry (TLD) postal dose validation, inter-comparison of different dosimeter/electrometers, and validity of Nd,water calibrations obtained from different calibration laboratories were analyzed to find out the extent of accuracy achievable. Nd,w factors in Gray/Coulomb calibrated at IBA, GmBH, Germany showed a mean variation of about 0.2% increase per year in three Farmer chambers, in three subsequent calibrations. Another ion chamber calibrated in different accredited laboratory (PTW, Germany) showed consistent Nd,w for 9 years period. The Strontium-90 beta check source response indicated long-term stability of the ion chambers within 1% for three chambers. Results of IAEA postal TL 'dose intercomparison' for three photon beams, 6 MV (two) and 15 MV (one), agreed well within our reported doses, with mean deviation of 0.03% (SD 0.87%) (n = 9). All the chamber/electrometer calibrated by a single SSDL realized absorbed doses in water within 0.13% standard deviations. However, about 1-2% differences in absorbed dose estimates observed when dosimeters calibrated from different calibration laboratories are compared in solid phantoms. Our data therefore imply that the dosimetry level maintained for clinical use of linear accelerator photon beams are within recommended levels of accuracy and uncertainities are within reported values.

    The United Kingdom’s National Nuclear Laboratory (NNL) has developed a radiation-mapping device that can locate and quantify radioactive hazards within contaminated areas of the nuclear industry. The device, known as RadBall™, consists of a colander-like outer collimator that houses a radiation-sensitive polymer sphere. The collimator has over two hundred small holes; thus, specific areas of the polymer sphere are exposed to radiation becoming increasingly more opaque in proportion to the absorbed dose. The polymer sphere is imaged in an optical-CT scanner that produces a high resolution 3D map of optical attenuation coefficients. Subsequent analysis of the optical attenuation data provides information on the spatial distribution of sources in a given area forming a 3D characterization of the area of interest. The RadBall™ technology has been deployed in a number of technology trials in nuclear waste reprocessing plants at Sellafield in the United Kingdom and facilities of the Savannah River National Laboratory (SRNL). This paper summarizes the tests completed at SRNL Health Physics Instrument Calibration Laboratory (HPICL). PMID:21617738

    2010-01-01

    In Japan, an ISO15189 accreditation system was started in 2005. To date, 47 hospitals have been accredited. In this session, I will present the merits of acquiring accreditation regarding ISO15189 based on our experience. Our hospital has 263 beds. The Clinical Examination Section consists of 12 staff (including 5 part-time workers): 7 in change of sample examination and 5 in charge of physiological examination. The annual number of samples is approximately 150,000. Samples collected on health checkups account for 90%. To improve the quality and service, assessment by third persons has been positively utilized in our hospital. Accreditation regarding ISO9001, ISO14001, ISO27001, privacy mark, hospital function assessment, the functional assessment of "ningen-dock"/health checkup hospitals, labor/hygiene service function assessment, and ISO15189 has been acquired. Patients may not recognize ISO. So, it must be utilized, considering that the acquisition of accreditation is not a goal but a starting point. Furthermore, cost-performance should be improved to achieve utilization-related merits. It is important to not only acquire accreditation but also help clinical staff and patients become aware of some changes/merits. Patients may consult a hospital for the following reasons: confidence in the hospital, and the staffs kind/polite attitudes. Long-term management strategies should be established without pursuing only short-term profits. I will introduce several merits of acquiring accreditation regarding ISO15189. Initially, incidental conditions for bids and appeal points include accreditation regarding ISO15189. Our corporation has participated in some competitive bids regarding health checkup business. In some companies, the bid conditions included ISO acquisition. In our hospital, clinical trials have been positively carried out. For participation in trials, hospitals must pass an institutional examination. However, ISO acquisition facilitates the preparation of

  17. Onboard calibration igneous targets for the Mars Science Laboratory Curiosity rover and the Chemistry Camera laser induced breakdown spectroscopy instrument

    International Nuclear Information System (INIS)

    Accurate characterization of the Chemistry Camera (ChemCam) laser-induced breakdown spectroscopy (LIBS) on-board composition targets is of prime importance for the ChemCam instrument. The Mars Science Laboratory (MSL) science and operations teams expect ChemCam to provide the first compositional results at remote distances (1.5-7 m) during the in situ analyses of the Martian surface starting in 2012. Thus, establishing LIBS reference spectra from appropriate calibration standards must be undertaken diligently. Considering the global mineralogy of the Martian surface, and the possible landing sites, three specific compositions of igneous targets have been determined. Picritic, noritic, and shergottic glasses have been produced, along with a Macusanite natural glass. A sample of each target will fly on the MSL Curiosity rover deck, 1.56 m from the ChemCam instrument, and duplicates are available on the ground. Duplicates are considered to be identical, as the relative standard deviation (RSD) of the composition dispersion is around 8%. Electronic microprobe and laser ablation inductively coupled plasma mass spectrometry (LA ICP-MS) analyses give evidence that the chemical composition of the four silicate targets is very homogeneous at microscopic scales larger than the instrument spot size, with RSD 0.1 wt.% using electronic microprobe, and 0.01 wt.% using LA ICP-MS. The LIBS campaign on the igneous targets performed under flight-like Mars conditions establishes reference spectra for the entire mission. The LIBS spectra between 240 and 900 nm are extremely rich, hundreds of lines with high signal-to-noise, and a dynamical range sufficient to identify unambiguously major, minor and trace elements. For instance, a first LIBS calibration curve has been established for strontium from [Sr] = 284 ppm to [Sr] = 1480 ppm, showing the potential for the future calibrations for other major or minor elements.

  19. Preliminary measurements of the establishment of a quality control programme for the activimeter calibration reference system

    International Nuclear Information System (INIS)

    The nuclear medicine techniques efficiency and safety depends on, beside other factors, a quality control programme, mainly regards to the nuclides activimeter utilization. The Calibration Laboratory of IPEN uses as a work standard, a tertiary standard system Capintec, calibrated at the Accredited Dosimetry Calibration Laboratory of the Medical radiation Research Center - University of Wisconsin. In this work, as preliminary measurements to establish a quality control programme for the activimeter calibration procedures, initially the repeatability and reproducibility (long term stability) tests were performed using a sealed check source of 133Ba. Later on, to complete this quality control programme other check sources (137Cs, 57Co, 60Co) will be used to perform the same tests. A series of 80 experiments of 10 measurements each has been carried out. The reference system showed a good behaviour to the repeatability test, considering the tolerance limits of 5%. The percent deviations of all tested sources in the activity measurements were lower 1% to 133Ba. (author)

    2013-06-01

    Polar organic chemical integrative samplers (POCIS) are useful for monitoring a wide range of chemicals, including polar pesticides, in water bodies. However, few calibration data are available, which limits the use of these samplers for time-weighted average concentration measurements in an aquatic medium. This work deals with the laboratory calibration of the pharmaceutical configuration of a polar organic chemical integrative sampler (pharm-POCIS) for calculating the sampling rates of 17 polar pesticides (1.15 ≤  logK(ow) ≤ 3.71) commonly found in water. The experiment, conducted for 21 days in a continuous water flow-through exposure system, showed an integrative accumulation of all studied pesticides for 15 days. Three compounds (metalaxyl, azoxystrobine, and terbuthylazine) remained integrative for the 21-day experiment. The sampling rates measured ranged from 67.9 to 279 mL day(-1) and increased with the hydrophobicity of the pesticides until reaching a plateau where no significant variation in sampling rate is observed when increasing the hydrophobicity.

    Metallic aluminium alloy foils exposed on the forward, comet-facing surface of the aerogel tray on the Stardust spacecraft are likely to have been impacted by the same cometary particle population as the dedicated impact sensors and the aerogel collector. The ability of soft aluminium alloy to record hypervelocity impacts as bowl-shaped craters offers an opportunistic substrate for recognition of impacts by particles of a wide potential size range. In contrast to impact surveys conducted on samples from low Earth orbit, the simple encounter geometry for Stardust and Wild 2, with a known and constant spacecraft-particle relative velocity and effective surface-perpendicular impact trajectories, permits closely comparable simulation in laboratory experiments. For a detailed calibration programme we have selected a suite of spherical glass projectiles of uniform density and hardness characteristics, with well-documented particle size range from 10 microns to nearly 100 microns. Light gas gun buckshot firings of these particles at approximately 6km s)exp -1) onto samples of the same foil as employed on Stardust have yielded large numbers of craters. Scanning electron microscopy of both projectiles and impact features has allowed construction of a calibration plot, showing a linear relationship between impacting particle size and impact crater diameter. The close match between our experimental conditions and the Stardust mission encounter parameters should provide another opportunity to measure particle size distributions and fluxes close to the nucleus of Wild 2, independent of the active impact detector instruments aboard the Stardust spacecraft.

    2014-06-01

    Full Text Available In the last 20 years in medical laboratories, numerous activities regarding quality and accreditation system were taken. Approach to this problem in European countries is different, so the task of the Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 to help the efforts to harmonize this issue. External quality control in clinical-chemical laboratories imposed the need for the implementation of quality management system. »Good laboratory practice« and its principles were adopted by nominated bodies, both international and national. In the beginning, the standard ISO 9001 was applied for certification and for accreditation EN 45001 and ISO Guide 25, which are prepared for testing and calibration laboratories. Standard ISO 17025 is the successor of the previous documents and for now it is a reference for mentioned laboratories. Accreditation Work Group of the Confederation of European societies for clinical chemistry (EC 4 made an amendment of the requirements for medical laboratories, which this standard describes. Standard draft ISO 15189 was adopted on February 2003 as a final version with requirements for medical laboratories.

  4. Study of neutron scattering contribution on Hp(10) and H*(10) calibration in the Brazilian National Low Scattering Laboratory

    International Nuclear Information System (INIS)

    The neutron scattering at the Low Scattering Laboratory of the Brazilian National Neutron Laboratory has been studied using three different methods. The measurements have been done with a traceable standard 241Am-Be from source-to-detector distances of 0.52-3.00 m. The obtained results with the variation distance methods are in agreement. Measurements with a large shadow cone are not worth for larger distances due to overshadowing. As the quantity required in a calibration is the response of the device being calibrated to the scattered neutron component in order to subtract this from the total response, for these purposes, the distance variation method must be used for each device. To quantify absolutely the scattering contribution on the quantity rates of fluence, Hp(10) and H*(10) in irradiation procedures, a Bonner sphere spectrometer with the shadow cone was employed. The evaluated scattering correction factor value may be employed for a distance of 1.00 m. Comparison of the results of scattering contribution obtained in this work with distance variation methods for the 8'' detector show good agreement from 0.52 to 3.00 m. Then, for calibration of any detector at the LSL of LN, the distance variation method has to be used for each of them. Using the shadow cone method, the agreement of the results is poor at the distance of 2.25 m because of the overshadowing. The too large shadow cone reduces significantly the neutron scattering measured by the BSS behind it. Therefore, for the studied configuration and distances, the correct values for fluence, Hp(10) and H*(10) quantity rates using this shadow cone may be employed only for a source-detector distance of 1.00 m. The use of this measured scattering correction factor may contribute to the reduction of the uncertainty of the operational quantity rate values at 1.00 m, stated in the CMC of LN. For evaluation of the scattering contribution in the neutron spectra for higher distances, it is necessary to use other

  5. Quality Assessment of Vertical Angular Deviations for Photometer Calibration Benches

    International Nuclear Information System (INIS)

    Lighting, both natural and electric, constitutes one of the most important aspects of the life of human beings, allowing us to see and perform our daily tasks in outdoor and indoor environments. The safety aspects of lighting are self-evident in areas such as road lighting, urban lighting and also indoor lighting. The use of photometers to measure lighting levels requires traceability obtained in accredited laboratories, which must provide an associated uncertainty. It is therefore relevant to study the impact of known uncertainty sources like the vertical angular deviation of photometer calibration benches, in order to define criteria to its quality assessment

  6. The role of the Secondary Laboratory of Dosimetric calibration in the implementation of the dosimetric magnitudes with radiological protection aims

    International Nuclear Information System (INIS)

    It is very well-known the paper of the net of secondary laboratories of dosimetric calibration of the OAS in the dissemination of the traceability of the dosimetric magnitudes: kerma in air and absorbed dose in water, to the radiotherapy departments, given the high accuracy and precision that require the radiotherapy treatments. However the LSCD has other important areas at least for the development, implementation and evaluation of dosimetric magnitudes denominated operative magnitudes with ends of radiological protection: environmental equivalent dose H*(10), directional equivalent dose H'(0.07) and personal equivalent dose Hp. In the case of radiological protection the LSCD-ININ has been implementing the infrastructure to give service of personal dosimetry for photons and beta particles in terms of the operative magnitudes. For photons: X and gamma rays, it account with a secondary pattern camera PTW T34035 gauged in H* and Hp in the primary laboratory of Germany PTB. For the case of beta radiation its account with an extrapolation camera PTW 23392 with a secondary pattern kit of sources of the type I, gauged in terms of H'(0.07) in the PTB. (Author)

    A gamma spectrometer including an HP Ge detector is commonly used for environmental radioactivity measurements. The efficiency of the detector should be calibrated for each geometry considered. Simulation of the calibration procedure with a validated computer program is an important auxiliary tool for environmental radioactivity laboratories. The MCNP code based on the Monte Carlo method has been applied to simulate the detection process in order to obtain spectrum peaks and determine the efficiency curve for each modelled geometry. The source used for measurements was a calibration mixed radionuclide gamma reference solution, covering a wide energy range (50-2000 keV). Two measurement geometries - Marinelli beaker and Petri boxes - as well as different materials - water, charcoal, sand - containing the source have been considered. Results obtained from the Monte Carlo model have been compared with experimental measurements in the laboratory in order to validate the model.

    The use of linear accelerators in radiotherapy is of great importance in Medicine, and according to international recommendations the electron beam dosimetry has to be performed using plane-parallel ionization chambers, previously calibrated in standard gamma radiation fields at accredited laboratories. In this work, calibration methods of plane-parallel ionization chambers used in dosimetry procedures of high energy electron beams of clinical accelerators were presented, tested and intercompared. The experiments were carried out using gamma radiation beams of {sup 60} Co at the Calibration Laboratory of Clinical Dosemeters at IPEN and electron beams od 4 to 16 MeV at the Radiotherapy Department of Hospital Israelita Albert Einstein, Sao Paulo. A method was chosen to be established at IPEN. Proposals of the calibration procedure, calibration certificate and data sheets are presented. (author)

  15. Dose calibrators quality controls in Switzerland: six years of experience

    International Nuclear Information System (INIS)

    In Switzerland, the legal use of open radioactive sources in nuclear medicine and the general requirements for quality controls are defined in a federal ordinance. The metrological traceability is guaranteed through a directive of the Swiss metrological office (M.E.T.A.S.) that requires each instrument to be monitored at least once a year through either a verification or an intercomparison. The verification is performed onsite by an accredited laboratory with a set of three gamma sources (Co-57, Cs-137 and Co-60) and - if applicable - a beta source (Sr-90/Y- 90). The intercomparison is made through conventional mail. A source of I-131 or Tc- 99 m is measured both in the nuclear medicine department and in an accredited laboratory. The maximum tolerated error is 10% for gamma sources and 20% for beta sources. This methodology guarantees that the instruments have a correct response for most of the energy range used in practice. Not all nuclides are systematically probed and manufacturers are ultimately responsible for the calibration factors. The precision of the measurements performed in Switzerland is satisfactory with only about 6% of the measurements out of the tolerances. This monitoring also allowed us to improve the skills of the personnel and update the park of instruments by getting rid of dose calibrators displaying old units. (authors)

  1. Art state of radioprotection laboratory of Centro Regional de Referencia para la Dosimetria: CNEA, CAE

    International Nuclear Information System (INIS)

    External radiation quantity can be measured in terms of, for example exposure, air kerma, ambient dose equivalent and personal dose equivalent by using radiation measuring instruments. Radiation survey instruments and dosimeters are usually used to determine the amount of radiation from exposure to ionizing radiation and they need to be calibrated to ensure that they give accurate reading with a certain uncertainties. Dosimetry Calibration Laboratories have to be able to fulfil the requirements for traceable and reliable calibrations. A way to demonstrate it is through comparisons with primary or accredited laboratories and the establishment of a quality system following the International Organization for Standardization (ISO) Guide 17025. The Secondary Standard Dosimetry Laboratory (SSDL) of the Argentina 'Centro Regional de Referencia para la Dosimetria (CRRD)', C.N.E.A, is the national centre for the calibration of measuring instruments used in radiation protection and radiotherapy. The main facilities related to radioprotection include a constant potential X-ray system with a 300 kV tube and a new Hopewell Designs, Inc. Irradiator gamma Model G10-2-2600 (lead attenuator of 2, 4 and 6cm). Reference standard dosimeters traceable to the BIPM Dosimetry Laboratory and the IAEA (International Atomic Energy Agency) Dosimetry Laboratory are used in the calibration procedures by comparison with points calibrated. In this work a compilation of data obtained from instruments calibration and dosimeters irradiation that were carried on in CRRD during the last years is presented. Reported data are: amount of instruments calibrated per month, per kind, manufacturer and model. At the end of the year is planning to do the first internal audit to could accredit the Radioprotection procedures next year. (author)

  5. Characterization and performance study of high-dose 60Co gamma-ray calibration laboratory for radiation processing

    International Nuclear Information System (INIS)

    The 60Co gamma-ray irradiation facility for high absorbed dose calibration at radiation processing dose level was originally designed and constructed in JAERI. Uncertainty in absorbed dose given at JAERI was estimated by reviewing its characteristics and dosimetry performance. Dosimeter calibration equipment consists of the two plaque 60Co gamma-ray radiation sources giving different dose rate range of 5-200 Gy/h and 400 Gy/h-20 kGy/h, a dosimeter holder stage with high-reproducible positioning, a parallel-plate ionization chamber for accurate measurement of exposure-rates, and an auxiliary temperature/humidity-controlled irradiation vessel for dosimeter calibration under specific irradiation condition. The characteristics of the irradiation field and dosimetry performance are sufficient to give a known dose to working dosimeters to be calibrated for absorbed doses in the range of 0.5 Gy to 160 kGy within a reasonable operation time, 8 h, with an uncertainty of ±2.2% at a 95% confidence level. Calibration of dosimeters giving known doses by transfer dosimetry employing alanine dosimeters calibrated at JAERI is also achievable with an uncertainty of ±3.4% at a 95% confidence level.

    The Department of Energy Radiological Calibration Intercomparison Program was initiated in January 1986, under the research portion of the DOE Laboratory Accreditation Program. The program operates via the exchange of transfer standards, consisting of instrument sets and standard secondary beta sources. There are two instrument sets and the scheduled use has been staggered such that one set is available for use during each month. One set of secondary standard beta sources is available for use bimonthly. During the 1986 fiscal year, five laboratories used the instrument sets and three laboratories used the beta source set. Results were reported for all the measurements. The average and one standard deviation of the ratios of participant results to Pacific Northwest Laboratory calibration values were 1.12 +- 0.17 for gamma measurements. Those ratios for the gamma measurements varied from 0.98 to 3.06. The larger differences of results from measurements performed at two facilities were directly attributable to unfamiliarity with the intercomparison instruments. The average and one standard deviation of the ratios of participant results to PNL calibration values obtained using the secondary /sup 90/Sr beta source was 1.02 +- 0.05, which is well within measurement uncertainties. The one participant who performed measurements using /sup 147/Pm and /sup 204/Tl sources obtained ratios of 0.68 and 1.11, respectively. No measurements were performed using neutron or x-ray sources.

    One of the practical problems with quantifying the amount of energy used by fish implanted with electromyogram (EMG) radio transmitters is that the signals emitted by the transmitter provide only a relative index of activity unless they are calibrated to the swimming speed of the fish. Ideally calibration would be conducted for each fish before it is released, but this is often not possible and calibration curves derived from more than one fish are used to interpret EMG signals from individuals which have not been calibrated. We tested the validity of this approach by comparing EMG data within three groups of three wild juvenile white sturgeon Acipenser transmontanus implanted with the same EMG radio transmitter. We also tested an additional six fish which were implanted with separate EMG transmitters. Within each group, a single EMG radio transmitter usually did not produce similar results in different fish. Grouping EMG signals among fish produced less accurate results than having individual EMG-swim speed relationships for each fish. It is unknown whether these differences were a result of different swimming performances among individual fish or inconsistencies in the placement or function of the EMG transmitters. In either case, our results suggest that caution should be used when applying calibration curves from one group of fish to another group of uncalibrated fish.

  10. Lessons learnt during the IAEA radiation monitoring services ISO17025 accreditation process

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency (the IAEA) has, in the Medium Term Strategy 2006-2011 (GOV/2005/8), stated that: 'a quality management culture needs to be created and sustained within the Secretariat along with the implementation of a quality management system' In compliance with this established goal, the Radiation Safety and Monitoring Section (RSM) of the Division of Radiation, Transport and Waste Safety (NSRW) has implemented a quality management system in the testing laboratory for radiation measurement, monitoring and protection which it operates for the monitoring of members of IAEA staff, individuals under contract, experts, trainees and visitors who may be exposed to radioactive materials or other sources of ionizing radiation. This system improves the efficiency and effectiveness of the operations within the testing laboratory. The system can also be used to in Member States to harmonize their occupational radiation exposure monitoring services, by providing a model installation for a quality management system. To confirm the conformity of staff, processes and equipment to the ISO17025 quality system, the system was submitted to the Austrian accreditation board for assessment. The testing laboratory was duly accredited in December 2006 and the accreditation certificate was issued in January 2007. A surveillance audit was also passed positively in November 2007. This accreditation is recognized worldwide through mutual recognition agreements with the European Cooperation for Accreditation (EA) and the International Laboratory Accreditation Cooperation (ILAC). This paper summarizes the lessons learnt during the accreditation process with the main focus on the validation of the methods, traceability and uncertainty budgets. Possible new considerations related to the mathematical simulation and its validity for accreditation purposes are also discussed. (author)

    Full Text Available Introduction: The Amana Regional Hospital Laboratory in Tanzania was selected, along with 11 other regional and district laboratories, to participate in a pilot programme for laboratory quality improvement using the Strengthening Laboratory Management Toward Accreditation (SLMTA training programme.Programme implementation: The SLMTA programme entailed hands-on learning, improvement projects between and after a three-workshop series, supervisory visits from an oversight team and an expert laboratory mentor to facilitate and coach the process. Audits were conducted at baseline, exit (approximately one year after baseline and follow-up (seven months after exit using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist. Quality stars (zero to five were awarded based on audit scores.Results: With a dedicated staff and strong leadership from laboratory management, Amana Laboratory implemented processes, policies and procedures recommended as elements of best laboratory practices. The laboratory improved from zero stars (36% at baseline to successfully achieving three stars (81% at exit. This was the highest score achieved by the 12 laboratories in the programme (the median exit score amongst the other laboratories was 58%. Seven months after completion of the programme, the laboratory regressed to one star (62%.Discussion: As the SLMTA improvement programme progressed, Amana Laboratory’s positive attitude and hard work prevailed. With the assistance of a mentor and the support of the facility’s management a strong foundation of good practices was established. Although not all improvements were maintained after the conclusion of the programme and the laboratory dropped to a one-star rating, the laboratory remained at a higher level than most laboratories in the programme.

  12. INPO accreditation - product definition for utility training

    International Nuclear Information System (INIS)

    As a part of its responsibility to promote training excellence, the Institute of Nuclear Power Operations (INPO) initiated an accreditation program in 1982 on behalf of its member utilities. The purpose of the accreditation program is to assist INPO members in developing and maintaining training programs that produce well-qualified, competent personnel to operate the nation's nuclear power plants. Accreditation formally recognizes nuclear utility training as meeting the INPO accreditation objectives and criteria for initial and continuing training programs for operations, maintenance, and technical personnel. The ultimate objective to be achieved by accreditation is to maintain high-quality training and enhance the professionalism of the personnel who operate the nuclear power plants. While initial accreditation represents recognition that quality training programs have been put in place at the nuclear power plants, the renewal of accreditation represents recognition that quality training programs have been put in place at the nuclear power plants, the renewal of accreditation will keep the training programs vital, effective, and up to high standards. The nuclear power industry has accepted the responsibility of striving for excellence in training its personnel to safely operate the power plants. The full use of accreditation and the accrediting process is an important means to fulfilling this responsibility

    The calibration system consists of a Victoreen Model 550 Electrometer, with ion chambers, which has been modified to incorporate a digital timer which is tripped at a predetermined value set on the electrometer. This system provides a precision, standardized gamma and x-ray calibration system which is calibrated at a Regional Calibrations Laboratory accredited by the AAPM. The modified system is designed to be portable for use in laboratories throughout the University and can be easily taken apart for ease of handling. The electronic modification is diagrammed and discussed as to ease of installation and compatibility wth the entire system. Comparisons are made between a Standard versus Modified Model 550 as to accuracy, precision and utility of operation. The comparisons are based on measurements taken of a ten curie Cobalt Sixty Calibration Well and several x-ray units. The calibration well exposure rates were varied over the range five mr/hr to 20 R/hr and x-ray exposures varied between several R/min to several hundred R/min and for a number of energy spectra

  19. Calibration of photon and beta ray sources used in brachytherapy. Guidelines on standardized procedures at Secondary Standards Dosimetry Laboratories (SSDLs) and hospitals

    International Nuclear Information System (INIS)

    It has generally been recognized that international harmonization in radiotherapy dosimetry is essential. Consequently, the IAEA has given much effort to this, for example by publishing a number of reports in the Technical Reports Series (TRS) for external beam dosimetry, most notably TRS-277 and more recently TRS-398. Both of these reports describe in detail the steps to be taken for absorbed dose determination in water and they are often referred to as 'dosimetry protocols'. Similar to TRS-277, it is expected that TRS-398 will be adopted or used as a model by a large number of countries as their national protocol. In 1996, the IAEA established a calibration service for low dose rate (LDR) 137 Cs brachytherapy sources, which is the most widely used source for treatment of gynecological cancer. To further enhance harmonization in brachytherapy dosimetry, the IAEA published in 1999 IAEA-TECDOC-1079 entitled 'Calibration of Brachytherapy Sources. Guidelines on Standardized Procedures for the Calibration of Brachytherapy Sources at Secondary Standard Dosimetry Laboratories (SSDLs) and Hospitals'. The report was well received and was distributed in a large number of copies to the members of the IAEA/WHO network of SSDLs and to medical physicists working with brachytherapy. The present report is an update of the aforementioned TECDOC. Whereas TECDOC-1079 described methods for calibrating brachytherapy sources with photon energies at or above those of 192Ir, the current report has a wider scope in that it deals with standardization of calibration of all the most commonly used brachytherapy sources, including both photon and beta emitting sources. The latter sources have been in use for a few decades already, but their calibration methods have been unclear. Methods are also described for calibrating sources used in the rapidly growing field of cardiovascular angioplasty. In this application, irradiation of the vessel wall is done in an attempt to prevent restenosis after

    The increasing scientific interest in nitric oxide (NO) necessitates the development of novel and simple methods of synthesising NO on a laboratory scale. In this study we have refined and developed a method of NO synthesis, using the neutral Griess reagent, which is inexpensive, simple to perform, and provides a reliable method of generating NO gas for in-vivo sensor calibration. The concentration of the generated NO stock solution was determined using UV-visible spectroscopy to be 0.28{+-}0.01 mmol L{sup -1}. The level of NO{sub 2}{sup -} contaminant, also determined using spectroscopy, was found to be 0.67{+-}0.21 mmol L{sup -1}. However, this is not sufficient to cause any considerable increase in oxidation current when the NO stock solution is used for electrochemical sensor calibration over physiologically relevant concentrations; the NO sensitivity of bare Pt-disk electrodes operating at +900 mV (vs. SCE) was 1.08 nA {mu}mol{sup -1} L, while that for NO{sub 2}{sup -} was 5.9 x 10{sup -3} nA {mu}mol{sup -1} L. The stability of the NO stock solution was also monitored for up to 2 h after synthesis and 30 min was found to be the time limit within which calibrations should be performed. (orig.)

    Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.

  2. Update on Calibration of the Lawrence Livermore National Laboratory Passive-Active Neutron Drum Shuffler for Measurement of Highly Enriched Uranium Oxide

    International Nuclear Information System (INIS)

    In October of 1999, Lawrence Livermore National Laboratory (LLNL) began an effort to calibrate the LLNL passive-active neutron (PAN) drum shuffler for measurement of highly enriched uranium (HEU) oxide. A single unit of certified reference material (CRM) 149 (Uranium (93% Enriched) Oxide - U3O8 Standard for Neutron Counting Measurements) was used to (1) develop a mass calibration curve for HEU oxide in the nominal range of 393 g to 3144 g 235U, and (2) perform a detailed axial and radial mapping of the detector response over a wide region of the PAN shuffler counting chamber. Results from these efforts were reported at the Institute of Nuclear Materials Management 4lSt Annual Meeting in July 2000. This paper describes subsequent efforts by LLNL to use a unit of CRM 146 (Uranium Isotopic Standard for Gamma Spectrometry Measurements) in consort with Monte Carlo simulations of the PAN shuffler response to CRM 149 and CRM 146 units and a selected set of containers with CRM 149-equivalent U3O8 to (1) extend the low range of the reported mass calibration curve to 10 g 235U, (2) evaluate the effect of U3O8 density (2.4 g/cm3 to 4.8 g/cm3) and container size (5.24 cm to 12.17 cm inside diameter and 6.35 cm to 17.72 cm inside height) on the PAN shuffler response, and (3) develop mass calibration curves for U3O8 enriched to 20.1 wt% 235U and 52.5 wt% 235U.

    The laboratory X-ray powder diffractometer is one of the primary analytical tools in materials science. It is applicable to nearly any crystalline material, and with advanced data analysis methods, it can provide a wealth of information concerning sample character. Data from these machines, however, are beset by a complex aberration function that can be addressed through calibration with the use of NIST Standard Reference Materials (SRMs). Laboratory diffractometers can be set up in a range of optical geometries; considered herein are those of Bragg-Brentano divergent beam configuration using both incident and diffracted beam monochromators. We review the origin of the various aberrations affecting instruments of this geometry and the methods developed at NIST to align these machines in a first principles context. Data analysis methods are considered as being in two distinct categories: those that use empirical methods to parameterize the nature of the data for subsequent analysis, and those that use model functions to link the observation directly to a specific aspect of the experiment. We consider a multifaceted approach to instrument calibration using both the empirical and model based data analysis methods. The particular benefits of the fundamental parameters approach are reviewed. PMID:26958446

  5. Guidelines for establishing quality systems in veterinary diagnostic testing laboratories. Report of a Joint FAO/IAEA consultants meeting/workshop. Draft

    International Nuclear Information System (INIS)

    The purpose of this report is to assist veterinary testing laboratories to develop and implement a quality system based on the OIE Standard 'Management and Technical Requirements for Laboratories Conducting Tests for Infectious Animal Diseases'. The introduction to the OIE Standard states: This document describes the OIE Standard for management and technical competence that serves as the basis for accreditation of laboratories that conduct tests for infectious animal diseases, especially those laboratories involved in testing for international trade. It contains the specific requirements unique to laboratories conducting tests for infectious animal diseases. These specific requirements represent an interpretation of the generally stated requirements of ISO/IEC 17025:1999, General requirements for the competence of testing and calibration laboratories (as outlined in Annex B of ISO/IEC 17025). Accreditation bodies that recognize the competence of such testing laboratories may use this Standard as the basis for their accreditation. This report gives an example-oriented overview of the structure and contents of critical documents and procedures such as Quality Manual (QM), Standard Operating Procedures (SOPs), etc. inherent to a quality system and describes the different stages in the implementation of the OIE Standard. For that reason it can be used as a practical guide for the production of necessary documents but also as a help to determine the status of a laboratory during its journey towards establishing a QS

    Full Text Available The design and calibration of a new hyperspectral Compact Laboratory Spectro-Goniometer (CLabSpeG is presented. CLabSpeG effectively measures the bidirectionalreflectance Factor (BRF of a sample, using a halogen light source and an AnalyticalSpectral Devices (ASD spectroradiometer. The apparatus collects 4356 reflectance datareadings covering the spectrum from 350 nm to 2500 nm by independent positioning of thesensor, sample holder, and light source. It has an azimuth and zenith resolution of 30 and15 degrees, respectively. CLabSpeG is used to collect BRF data and extract BidirectionalReflectance Distribution Function (BRDF data of non-isotropic vegetation elements suchas bark, soil, and leaves. Accurate calibration has ensured robust geometric accuracy of theapparatus, correction for the conicality of the light source, while sufficient radiometricstability and repeatability between measurements are obtained. The bidirectionalreflectance data collection is automated and remotely controlled and takes approximatelytwo and half hours for a BRF measurement cycle over a full hemisphere with 125 cmradius and 2.4 minutes for a single BRF acquisition. A specific protocol for vegetative leafcollection and measurement was established in order to investigate the possibility to extractBRDF values from Fagus sylvatica L. leaves under laboratory conditions. Drying leafeffects induce a reflectance change during the BRF measurements due to the laboratorySensors 2007, 7 1847 illumination source. Therefore, the full hemisphere could not be covered with one leaf. Instead 12 BRF measurements per leaf were acquired covering all azimuth positions for a single light source zenith position. Data are collected in radiance format and reflectance is calculated by dividing the leaf cycle measurement with a radiance cycle of a Spectralon reference panel, multiplied by a Spectralon reflectance correction factor and a factor to correct for the conical effect of the light

  15. Ion chamber absorbed dose calibration coefficients, ND,w, measured at ADCLs: Distribution analysis and stability

    International Nuclear Information System (INIS)

    Purpose: To analyze absorbed dose calibration coefficients, ND,w, measured at accredited dosimetry calibration laboratories (ADCLs) for client ionization chambers to study (i) variability among ND,w coefficients for chambers of the same type calibrated at each ADCL to investigate ion chamber volume fluctuations and chamber manufacturing tolerances; (ii) equivalency of ion chamber calibration coefficients measured at different ADCLs by intercomparing ND,w coefficients for chambers of the same type; and (iii) the long-term stability of ND,w coefficients for different chamber types by investigating repeated chamber calibrations. Methods: Large samples of ND,w coefficients for several chamber types measured over the time period between 1998 and 2014 were obtained from the three ADCLs operating in the United States. These are analyzed using various graphical and numerical statistical tests for the four chamber types with the largest samples of calibration coefficients to investigate (i) and (ii) above. Ratios of calibration coefficients for the same chamber, typically obtained two years apart, are calculated to investigate (iii) above and chambers with standard deviations of old/new ratios less than 0.3% meet stability requirements for accurate reference dosimetry recommended in dosimetry protocols. Results: It is found that ND,w coefficients for a given chamber type compared among different ADCLs may arise from differing probability distributions potentially due to slight differences in calibration procedures and/or the transfer of the primary standard. However, average ND,w coefficients from different ADCLs for given chamber types are very close with percent differences generally less than 0.2% for Farmer-type chambers and are well within reported uncertainties. Conclusions: The close agreement among calibrations performed at different ADCLs reaffirms the Calibration Laboratory Accreditation Subcommittee process of ensuring ADCL conformance with National Institute of

  16. Art State of Radioprotection Laboratory of Centro Regional de Referencia para la Dosimetria, C.N.E.A, C.A.E

    International Nuclear Information System (INIS)

    External radiation quantity can be measured in terms of, for example exposure, air kerma, ambient dose equivalent and personal dose equivalent by using radiation measuring instruments. Radiation survey instruments and dosimeters are usually used to determine the amount of radiation from exposure to ionizing radiation and they need to be calibrated to ensure that they give accurate reading with a certain uncertainties. Dosimetry Calibration Laboratories have to be able to fulfil the requirements for traceable and reliable calibrations. A way to demonstrate it is through comparisons with primary or accredited laboratories and the establishment of a quality system following the International Organization for Standardization (ISO) Guide 17025. The Secondary Standard Dosimetry Laboratory (SSDL) of the Argentina 'Centro Regional de Referencia para la Dosimetria (CRRD)', C.N.E.A, is the national centre for the calibration of measuring instruments used in radiation protection and radiotherapy. The main facilities related to radioprotection include a constant potential x-ray system with a 300 kV tube and a new Hopewell Designs, Inc. Irradiator gamma Model G10-2-2600 (lead attenuator of 2, 4 and 6cm). Reference standard dosimeters traceable to the BIPM Dosimetry Laboratory and the IAEA (International Atomic Energy Agency) Dosimetry Laboratory are used in the calibration procedures by comparison with points calibrated. In this work a compilation of data obtained from instruments calibration and dosimeters irradiation that were carried on in CRRD during the last years is presented. Reported data are: amount of instruments calibrated per month, per kind, manufacturer and model. At the end of the year is planning to do the first internal audit to could accredit the Radioprotection procedures next year. (author)

  17. Training and Accreditation for Radon Professionals in Sweden

    International Nuclear Information System (INIS)

    Radon training courses and seminars of different kinds have been arranged in Sweden since the early 1980s. A commercial educational company initiated the first regular training courses in 1987. Up to 1990 about 400 persons had attended courses in radon measurement and radon mitigation methods. In 1991 the first in a series of courses focussed on radon from the ground and production of radon risk maps organised. From 1991 it has been possible to obtain accreditation for measurements of indoor radon in Sweden and from 1997 also for measurements of radon in water. Even if accreditation s is voluntary, in Sweden accredited laboratories perform most measurements, both for indoor air and water. A condition for accreditation in to have passed the examination following the training courses at SSI, SO far, three major companies have obtained accreditation for measurement of indoor radon and four have been accredited for measurements of radon in water. Education on radon is also given at universities and institutes of technology. A two-day course is included in the education for environmental health officers. A number of training courses aimed at real state agents have been organised by SSI through the years. During the autumn of 2001 altogether 400 authorised real estate agents attended a series of regional half-day courses. In 1995 SSI arranged an international training course, Radon Indoor Risk and Remedial Actions, in Stockholm for the European commission. About 40 scientists from all over Europe attended the course, which much appreciated by the participants. Today SSI's Radon Training Programme comprises five different courses, a Basic radon Course and four continuation courses: Radon measurements, Radon remedial measures, Radon in water and Radon investigation and risk map production. The courses are arranged twice a year, in spring and autumn, except the Radon risk map production course, which is arranged about every second year. Altogether, between 1991 and 2003

  19. Preliminary development of a comprehensive calibrated subsurface pathway simulator for the subsurface disposal area at the Idaho National Engineering and Environmental Laboratory

    International Nuclear Information System (INIS)

    The first detailed comprehensive simulation study to evaluate fate and transport of low-level, mixed, and transuranic wastes buried in the Subsurface Disposal Area (SDA) at the Idaho National Engineering and Environmental Laboratory (INEEL) has recently been conducted. The study took advantage of pertinent information relating to describing aqueous- and vapor-phase movement of contaminants in the primarily fractured basalt subsurface. The study included spatially and temporally variable infiltration, barometric pressure changes, positive down-hole air pressure during well drilling, vapor-vacuum extraction, and regional hydraulic gradients. Use of the TETRAD simulation code allowed all the pertinent information to be included into a single comprehensive model of the SDA subsurface. An overview of the model implementation and comparisons of calibrated model results to the observed vadose zone water distribution, volatile organic vapor concentrations, and aqueous concentrations of volatile organics and nitrate are presented. Additionally, comparisons between simulated and observed concentrations for other contaminants which were not used for model calibration are made. As part of this modeling exercise, inadequacies in the available data relating to characterization of non-sorbing aqueous-phase transport have been identified. Even with the identified data inadequacies, the comparisons between simulated and observed contaminants along with the calibration results give confidence that the model is a conservative representation of flow and transport in the subsurface at the SDA. The results from this modeling study are being used to guide additional data collection activities at the SDA for purposes of increasing confidence in the appropriateness of model predictions

  6. Laboratory calibration and field testing of the Chemcatcher-Metal for trace levels of rare earth elements in estuarine waters.

    Petersen, Jördis; Pröfrock, Daniel; Paschke, Albrecht; Broekaert, Jose A C; Prange, Andreas

    2015-10-01

    Little knowledge is available about water concentrations of rare earth elements (REEs) in the marine environment. The direct measurement of REEs in coastal waters is a challenging task due to their ultra-low concentrations as well as the high salt content in the water samples. To quantify these elements at environmental concentrations (pg L(-1) to low ng L(-1)) in coastal waters, current analytical techniques are generally expensive and time consuming, and require complex chemical preconcentration procedures. Therefore, an integrative passive sampler was tested as a more economic alternative sampling approach for REE analysis. We used a Chemcatcher-Metal passive sampler consisting of a 3M Empore Chelating Disk as the receiving phase, as well as a cellulose acetate membrane as the diffusion-limiting layer. The effect of water turbulence and temperature on the uptake rates of REEs was analyzed during 14-day calibration experiments by a flow-through exposure tank system. The sampling rates were in the range of 0.42 mL h(-1) (13 °C; 0.25 m s(-1)) to 4.01 mL h(-1) (13 °C; 1 m s(-1)). Similar results were obtained for the different REEs under investigation. The water turbulence was the most important influence on uptake. The uptake rates were appropriate to ascertain time-weighted average concentrations of REEs during a field experiment in the Elbe Estuary near Cuxhaven Harbor (exposure time 4 weeks). REE concentrations were determined to be in the range 0.2 to 13.8 ng L(-1), where the highest concentrations were found for neodymium and samarium. In comparison, most of the spot samples measured along the Chemcatcher samples had REE concentrations below the limit of detection, in particular due to necessary dilution to minimize the analytical problems that arise with the high salt content in marine water samples. This study was among the first efforts to measure REE levels in the field using a passive sampling approach. Our results suggest that passive samplers could be

    In the beginnings of the sixty years an urgent necessity is presented mainly in the developing countries, of improving in important form the accuracy in the dosimetry of external faces in therapy of radiations (radiotherapy centers), mainly in the calibration of ''clinical dosemeters''. In 1976 the International Atomic Energy Agency, (IAEA), and the World Health Organization, (WHO), they carried out a mutual agreement with regard to the establishment and operation of a net of Secondary Patron Laboratories of Dosimetry, (LSCD). The necessity to establish measure patterns in the field of the dosimetry of the ionizing radiations, is necessary, to have an accuracy but high in the dosimetry of the radiation beams in therapy which is highly dependent of the dose given to the tumor of those patient with cancer. Similar levels of accuracy are required in protection measures to the radiation with an acceptable smaller accuracy, however, when the personal dosemeters are used to determine the doses received by the individuals under work conditions, such mensurations in therapy of radiations and radiological protection will have traceability through a chain of comparisons to primary or national patterns. The traceability is necessary to assure the accuracy and acceptability of the dosimetric measures, as well as, the legal and economic implications. The traceability is also necessary in the dosimetry of high dose like in the sterilization of different products. The main function of the LSCD is to provide a service in metrology of ionizing radiations, maintaining the secondary or national patterns, which have a traceability to the International System of measures, which is based for if same in the comparison of patterns in the Primary Laboratories of Dosimetry (LPD) under the auspice of the International Office of Weights and Measure (BIPM). The secondary and national patterns in the LSCD constitute in Mexico, the national patterns of the magnitudes in the

    Calibration laboratories are faced with the need to become accredited or registered to one or more quality standards. One requirement common to all of these standards is the need to have in place a measurement assurance program. What is a measurement assurance program? Brian Belanger, in Measurement Assurance Programs: Part 1, describes it as a {open_quotes}quality assurance program for a measurement process that quantifies the total uncertainty of the measurements (both random and systematic components of error) with respect to national or designated standards and demonstrates that the total uncertainty is sufficiently small to meet the user`s requirements.{close_quotes} Rolf Schumacher is more specific in Measurement Assurance in Your Own Laboratory. He states, {open_quotes}Measurement assurance is the application of broad quality control principles to measurements of calibrations.{close_quotes} Here, the focus is on one important part of any measurement assurance program: implementation of statistical process control (SPC). Paraphrasing Juran`s Quality Control Handbook, a process is in statistical control if the only observed variations are those that can be attributed to random causes. Conversely, a process that exhibits variations due to assignable causes is not in a state of statistical control. Finally, Carrol Croarkin states, {open_quotes}In the measurement assurance context the measurement algorithm including instrumentation, reference standards and operator interactions is the process that is to be controlled, and its direct product is the measurement per se. The measurements are assumed to be valid if the measurement algorithm is operating in a state of control.{close_quotes} Implicit in this statement is the important fact that an out-of-control process cannot produce valid measurements. 7 figs.

    Standards for accreditation of laboratories as in ISO 9001 in section: 4.11 require inspection, measuring and equipment testing; likewise, IEC 17025: 2005 in section: 5.5.2 requires the equipment to be calibrated or verified before being put into use. In our laboratory, quality control is often accomplished by standards set done by the laboratory scientists themselves; however, at present, Hellma secondary calibration standards (4026 - Holmium oxide - Filters: F0, F2, F3, F4 and filter didymium - F7) have been used in order to verify if errors in the laboratory have been close to the 1-2% margin. Control graphs were made by using the results of synthetically prepared standards and standardized spectral calibration certificates. The set of secondary calibration standards permits to check the accuracy of the spectrophotometers used in research for both the absorbance in the visible spectrum (at 440, 465, 546, 590 and 635 nm wavelengths) and for the wavelengths (270, 280, 300, 320 nm) of the ultraviolet light. Filters (F0, F2, F3, F4 and F7) are stable and do not suffer the influence of temperature (the influence is negligible), the F0 filter was being used as a blank. The purpose is to verify whether the spectrometer needs adjustments, an important procedure to check absorbance stability, baseline flatness, slit width accuracy and stray radiation. The calibration tests are performed annually in our laboratory and recalibration of Hellma secondary standards is recommended every two years. The results show that the Chemical Dosimetry Laboratory in CRCN has a calibrated spectrophotometer and their synthetic standards for Fricke dosimetry could be used as an alternative method for testing the proficiency and competence of calibration laboratories in accordance with the regulations and standards.

    2008-10-01

    The Joint Accreditation Committee of the International Society for Cellular Therapy (ISCT) and European Group for Blood and Marrow Transplantation (EBMT), known as JACIE, is a nonprofit body established for the purposes of assessment and accreditation in the field of haemopoietic SCT (HSCT). The committee was established in 1999 with the aim of creating a standardized system of accreditation officially recognized across Europe and based on the accreditation standards established by the US-based Foundation for the Accreditation of Cellular Therapy (FACT). The major objectives of JACIE are to improve the quality of HSCT in Europe by providing a means whereby transplant centres, cell collection facilities and processing facilities can demonstrate high-quality practice. JACIE launched its official inspection programme in January 2004, and since then more than 35 centres in Europe have been inspected. The history of paediatric-specific accreditation guidelines has lagged behind the overall development but is now incorporated within the standards. There is now acknowledgement that a paediatric transplant team will be headed by a paediatric programme director, that an independent paediatric unit will perform no less than 10 allogeneic transplants in children under the age of 18 per year, be looked after by nurses and junior doctors specifically trained in paediatric practice and have access to paediatric subspecialties with an intensive care unit on site. Paediatric units will be examined by a paediatric-trained inspector. Remaining issues of difference with the guidelines relate to the numbers required for accreditation in combined units. Overall, the paediatric community in Europe has embraced the JACIE guidelines. JACIE is working more closely with other international organizations in cellular therapy to develop international standards for all aspects of SCT. The recent implementation of Directive 2004/23/EC has provided an impetus for the implementation of JACIE in

  18. Mammography calibration: Factor or fit?

    International Nuclear Information System (INIS)

    Dose measurements in mammography x-ray have become more important and a basic path in quality assurance programmes. It is recognized by the international guidelines that it is necessary to have calibration services offered for mammography beams in order to help the improvement of the clinical diagnosis. Major efforts have been made by several laboratories in order to establish an appropriate and traceable calibration infrastructure and to provide the basis for a quality control programme in mammography. The indication of a dosimeter, whose reference point is positioned at the point of test, is compared with the conventional true value of the quantity to be measured. The calibration coefficient is then the ratio of the conventional true value to the indicated. The Primary Standard Dosimetry Laboratory - PSDL or the Secondary Standard Dosimetry Laboratory - SSDL provides the calibration coefficient of the dosimeters in reference to the Half Value Layers - HVL implemented in their laboratories. The dosimetry calibration data is enough when the user has the same system as the laboratory where the ionization chamber has been calibrated. However, there are other calibration systems that have different calibration qualities implemented using different combinations of anode and filter and, therefore, there is no direct relation with the calibration coefficient. How to deal with this? There are two different ways to obtain calibration coefficients when the user's implemented qualities are different from the calibration laboratory's qualities. The first is the interpolation of each calibration coefficient stated in the certificate. The second is the fit of all calibration coefficients, separately for non-attenuated and attenuated beam qualities, to obtain a function by which the calibration coefficients can be determined at each beam quality. The second one includes the statistical fluctuation. The dosimetry calibration data must fit an analytical form, as for example a

    The ChemCam instrument package on the Mars Science Laboratory rover, Curiosity, is the first planetary science instrument to employ laser-induced breakdown spectroscopy (LIBS) to determine the compositions of geological samples on another planet. Pre-processing of the spectra involves subtracting the ambient light background, removing noise, removing the electron continuum, calibrating for the wavelength, correcting for the variable distance to the target, and applying a wavelength-dependent correction for the instrument response. Further processing of the data uses multivariate and univariate comparisons with a LIBS spectral library developed prior to launch as well as comparisons with several on-board standards post-landing. The level-2 data products include semi-quantitative abundances derived from partial least squares regression. A LIBS spectral library was developed using 69 rock standards in the form of pressed powder disks, glasses, and ceramics to minimize heterogeneity on the scale of the observation (350-550 μm dia.). The standards covered typical compositional ranges of igneous materials and also included sulfates, carbonates, and phyllosilicates. The provenance and elemental and mineralogical compositions of these standards are described. Spectral characteristics of this data set are presented, including the size distribution and integrated irradiances of the plasmas, and a proxy for plasma temperature as a function of distance from the instrument. Two laboratory-based clones of ChemCam reside in Los Alamos and Toulouse for the purpose of adding new spectra to the database as the need arises. Sensitivity to differences in wavelength correlation to spectral channels and spectral resolution has been investigated, indicating that spectral registration needs to be within half a pixel and resolution needs to match within 1.5 to 2.6 pixels. Absolute errors are tabulated for derived compositions of each major element in each standard using PLS regression

    Full Text Available Abstract Background Service accreditation is a structured process of recognising and promoting performance and adherence to standards. Typically, accreditation agencies either receive standards from an authorized body or develop new and upgrade existing standards through research and expert views. They then apply standards, criteria and performance indicators, testing their effects, and monitoring compliance with them. The accreditation process has been widely adopted. The international investments in accreditation are considerable. However, reliable evidence of its efficiency or effectiveness in achieving organizational improvements is sparse and the value of accreditation in cost-benefit terms has yet to be demonstrated. Although some evidence suggests that accreditation promotes the improvement and standardization of care, there have been calls to strengthen its research base. In response, the ACCREDIT (Accreditation Collaborative for the Conduct of Research, Evaluation and Designated Investigations through Teamwork project has been established to evaluate the effectiveness of Australian accreditation in achieving its goals. ACCREDIT is a partnership of key researchers, policymakers and agencies. Findings We present the framework for our studies in accreditation. Four specific aims of the ACCREDIT project, which will direct our findings, are to: (i evaluate current accreditation processes; (ii analyse the costs and benefits of accreditation; (iii improve future accreditation via evidence; and (iv develop and apply new standards of consumer involvement in accreditation. These will be addressed through 12 interrelated studies designed to examine specific issues identified as a high priority. Novel techniques, a mix of qualitative and quantitative methods, and randomized designs relevant for health-care research have been developed. These methods allow us to circumvent the fragmented and incommensurate findings that can be generated in small

  6. Calibration and performance testing of survey meters used in ionizing radiation applications in Greece

    International Nuclear Information System (INIS)

    Radiation protection monitoring is an essential activity in any facility using radioactive sources or isotopes, for medical, industrial, research and other ionizing radiation application. Quantification of the radiation levels in a workplace in order to designate an area as controlled or supervised or to estimate the effectiveness of shielding is frequently needed. According to the Greek legislation the levels of ionizing radiation must be adequately monitored and the equipment used for this purpose should be tested and calibrated at appropriate intervals that should not exceed two years. The Ionizing Radiation Calibration Laboratory (H.I.R.C.L.) of the Greek Atomic Energy Commission (G.A.E.C.) has established a detailed calibration procedure for radiation protection equipment in order to investigate the accuracy of the various detectors and to provide homogeneous response of their use in Greece. H.I.R.C.L. has been accredited according to E.N./ISO 17 025, for radiation protection calibrations by the Hellenic Accreditation Council, E.S.Y.D.. This study summarizes the results of calibrations and performance testing in nearly 650 survey meters of different types. For each instrument, operational characteristics such as, accuracy and linearity in every scale, energy and angular dependence have been studied. The calibration factor in each scale was also determined. The measured values were compared to the suggested limits. The results were classified in seven dose intervals (from 0,1 + Sv/h up to >1 Sv/h). The statistical distribution showed tales that exceeded the + 20% criterion of accuracy in all dose intervals. About 20% of them showed non - linearity in their response. Moreover, about 8,5% of the instruments with more than one operational scales, showed accuracy discrepancies in some scales, while the others where found to operate satisfactory. Almost 9% of the instruments were found to be out of order because of technical and operational malfunctions. About 270

    The ChemCam instrument package on the Mars Science Laboratory rover, Curiosity, is the first planetary science instrument to employ laser-induced breakdown spectroscopy (LIBS) to determine the compositions of geological samples on another planet. Pre-processing of the spectra involves subtracting the ambient light background, removing noise, removing the electron continuum, calibrating for the wavelength, correcting for the variable distance to the target, and applying a wavelength-dependent correction for the instrument response. Further processing of the data uses multivariate and univariate comparisons with a LIBS spectral library developed prior to launch as well as comparisons with several on-board standards post-landing.

    2014-01-01

    Quality in health care is important as it is directly linked with patient safety. Quality as we know is driven either by regulation or by market demand. Regulation in most developing countries has not been effective, as there is shortage of health care providers and governments have to be flexible. In such circumstances, quality has taken a back seat. Accreditation symbolizes the framework for quality governance of a hospital and is based on optimum standards. Not only is India establishing numerous state of the art hospitals, but they are also experiencing an increase in demand for quality as well as medical tourism. India launched its own accreditation system in 2006, conforming to standards accredited by ISQua. This article shows the journey to accreditation in India and describes the problems encountered by hospitals as well as the benefits it has generated for the industry and patients. PMID:24938026

    The indoor calibration of brightness sensors requires extremely low values of irradiance in the most accurate and reproducible way. In this work the testing equipment of an ISO 17025 accredited laboratory for electrical testing, qualification and type approval of solar photovoltaic modules was modified in order to test the linearity of the instruments from few mW/cm2 down to fractions of nW/cm2, corresponding to levels of simulated brightness from 6 to 19 mag/arcsec2. Sixteen Sky Quality Meter (SQM) produced by Unihedron, a Canadian manufacturer, were tested, also assessing the impact of the ageing of their protective glasses on the calibration coefficients and the drift of the instruments. The instruments are in operation on measurement points and observatories at different sites and altitudes in Southern Switzerland, within the framework of OASI, the Environmental Observatory of Southern Switzerland. The authors present the results of the calibration campaign: linearity; brightness calibration, with and without protective glasses; transmittance measurement of the glasses; and spectral responsivity of the devices. A detailed uncertainty analysis is also provided, according to the ISO 17025 standard.

    Full Text Available Abstract Background One way to improve quality and safety in healthcare organizations (HCOs is through accreditation. Accreditation is a rigorous external evaluation process that comprises self-assessment against a given set of standards, an on-site survey followed by a report with or without recommendations, and the award or refusal of accreditation status. This study evaluates how the accreditation process helps introduce organizational changes that enhance the quality and safety of care. Methods We used an embedded multiple case study design to explore organizational characteristics and identify changes linked to the accreditation process. We employed a theoretical framework to analyze various elements and for each case, we interviewed top managers, conducted focus groups with staff directly involved in the accreditation process, and analyzed self-assessment reports, accreditation reports and other case-related documents. Results The context in which accreditation took place, including the organizational context, influenced the type of change dynamics that occurred in HCOs. Furthermore, while accreditation itself was not necessarily the element that initiated change, the accreditation process was a highly effective tool for (i accelerating integration and stimulating a spirit of cooperation in newly merged HCOs; (ii helping to introduce continuous quality improvement programs to newly accredited or not-yet-accredited organizations; (iii creating new leadership for quality improvement initiatives; (iv increasing social capital by giving staff the opportunity to develop relationships; and (v fostering links between HCOs and other stakeholders. The study also found that HCOs' motivation to introduce accreditation-related changes dwindled over time. Conclusions We conclude that the accreditation process is an effective leitmotiv for the introduction of change but is nonetheless subject to a learning cycle and a learning curve.

  4. Design, fabrication, installation and shielding integrity testing of source storage container for automatic source movement system used in TLD calibration facility

    International Nuclear Information System (INIS)

    A state-of-art TLD laboratory has been commissioned in January 2000 at Radiological Safety Division of Indira Gandhi Centre for Atomic Research (IGCAR). The laboratory provides personnel monitoring service to 2000 occupational workers from Indira Gandhi Centre for Atomic Research and Bhabha Atomic Research Centre facilities. The laboratory has been accredited by the Radiation Safety Systems Division (RSSD), Bhabha Atomic Research Centre (BARC) since year 2002. The laboratory has exclusive facility for the calibration of the TLD cards. As apart of accreditation procedure and taking into account of geometry effect, the dose rate at the card position is determined by the accreditation authorities by using graphite chamber (secondary or national standard instrument) and often re estimated by a condenser R meter (M/s Victoreen, Germany) by our laboratory. As per the regulatory requirement, the exposure protocols should be automated. Towards this an automatic source movement system has been augmented in the calibration facility. By using the system, the source will be brought to the irradiation position by pneumatically and exposures will be terminated by counter, timer and triggering system. To accomplish this task a lead container has been designed, fabricated and mounted at the beneath of the calibration table for the storage of source. As per the automation process, a lead container for the source storage has been designed and installed beneath to the Calibration Table. The container was designed to hold a 3Ci 137Cs source, but present activity of the source is 1.2Ci. Hence, the shielding integrity was tested with higher active source (1.7Ci 60Co). The dose rate measured outside on the circumference of the container at the middle of the source is found to be the same as calculated using QAD CGGP calculations. The top plug is so designed to avoid inadvertent upward movement of the source. Though, the shielding was not adequate on top of the top plug, however it does

    2007-01-01

    The Council on Aviation Accreditation (CAA) was established in 1988 in response to the need for formal, specialized accreditation of aviation academic programs, as expressed by institutional members of the University Aviation Association (UAA). The first aviation programs were accredited by the CAA in 1992, and today, the CAA lists 60 accredited programs at 21 institutions nationwide. Although the number of accredited programs has steadily grown, there are currently only 20 percent of UAA member institutions with CAA accredited programs. In an effort to further understand this issue, a case study of the CAA was performed, which resulted in a two-part case study report. Part one addressed the historical foundation of the organization and the current environment in which the CAA functions. Part two focuses on the following questions: (a) what are some of the costs to a program seeking CAA accreditation (b) what are some fo the benefits of being CAA accredited; (c) why do programs seek CAA accreditation; (d) why do programs choose no to seek CAA accreditation; (e) what role is the CAA playing in the international aviation academic community; and (f) what are some possible strategies the CAA may adopt to enhance the benefits of CAA accreditation and increase the number of CAA accredited programs. This second part allows for a more thorough understanding of the contemporary issued faced by the organization, as well as alternative strategies for the CAA to consider in an effort to increase the number of CAA accredited programs and more fully fulfill the role of the CAA in the collegiate aviation community.

  13. A Method of Determining Accuracy and Precision for Dosimeter Systems Using Accreditation Data

    International Nuclear Information System (INIS)

    A study of the uncertainty of dosimeter results is required by the national accreditation programs for each dosimeter model for which accreditation is sought. Typically, the methods used to determine uncertainty have included the partial differentiation method described in the U.S. Guide to Uncertainty in Measurements or the use of Monte Carlo techniques and probability distribution functions to generate simulated dose results. Each of these techniques has particular strengths and should be employed when the areas of uncertainty are required to be understood in detail. However, the uncertainty of dosimeter results can also be determined using a Model II One-Way Analysis of Variance technique and accreditation testing data. The strengths of the technique include (1) the method is straightforward and the data are provided under accreditation testing and (2) the method provides additional data for the analysis of long-term uncertainty using Statistical Process Control (SPC) techniques. The use of SPC to compare variances and standard deviations over time is described well in other areas and is not discussed in detail in this paper. The application of Analysis of Variance to historic testing data indicated that the accuracy in a representative dosimetry system (Panasonic(regsign) Model UD-802) was 8.2%, 5.1%, and 4.8% and the expanded uncertainties at the 95% confidence level were 10.7%, 14.9%, and 15.2% for the Accident, Protection Level-Shallow, and Protection Level-Deep test categories in the Department of Energy Laboratory Accreditation Program, respectively. The 95% level of confidence ranges were (0.98 to 1.19), (0.90 to 1.20), and (0.90 to 1.20) for the three groupings of test categories, respectively.

    Background Quality indicators determine the quality of actual practice in reference to standard criteria. The Community Pharmacy Association (Thailand), with technical support from the International Pharmaceutical Federation, developed a tool for quality assessment and quality improvement at community pharmacies. This tool has passed validity and reliability tests, but has not yet had feasibility testing. Objective (1) To test whether this quality tool could be used in routine settings. (2) To compare quality scores between accredited independent and accredited chain pharmacies. Setting Accredited independent pharmacies and accredited chain pharmacies in the north eastern region of Thailand. Methods A cross sectional study was conducted in 34 accredited independent pharmacies and accredited chain pharmacies. Quality scores were assessed by observation and by interviewing the responsible pharmacists. Data were collected and analyzed by independent t-test and Mann-Whitney U test as appropriate. Results were plotted by histogram and spider chart. Main outcome measure Domain's assessable scores, possible maximum scores, mean and median of measured scores. Results Domain's assessable scores were close to domain's possible maximum scores. This meant that most indicators could be assessed in most pharmacies. The spider chart revealed that measured scores in the personnel, drug inventory and stocking, and patient satisfaction and health promotion domains of chain pharmacies were significantly higher than those of independent pharmacies (p pharmacies and chain pharmacies in the premise and facility or dispensing and patient care domains. Conclusion Quality indicators developed by the Community Pharmacy Association (Thailand) could be used to assess quality of practice in pharmacies in routine settings. It is revealed that the quality scores of chain pharmacies were higher than those of independent pharmacies. PMID:27118461

    International Nuclear Information System (INIS)

    Full text: The activities of the Health Physics Laboratory at the Institute of Nuclear Physics in Cracow are principally research in the general area of radiation physics, and radiation protection of the employees of the Institute of Nuclear Physics. Theoretical research concerns modelling of radiation effects in radiation detectors and studies of concepts in radiation protection. Experimental research, in the general area of solid state dosimetry, is primarily concerned with thermoluminescence (TL) dosimetry, and more specially: development of LiF:Mg, Ti for medical applications in conventional and hadron radiotherapy, and of LiF:Mg, Cu, P for dosimetry of external low-level ionising radiation in the environment. Radiation measurements of radon concentration in dwellings and in soil gas are also performed using track detectors. The Laboratory provides expert advice on radiation protection regulations at national and international levels. Routine work of the Health Physics Laboratory involves design and maintenance of an in-house developed TL-based personnel dosimetry system for over 200 radiation workers at the INP, monitoring and supervision of radiation safety on INP premises, and advising other INP laboratories on all matters pertaining to radiation safety. We also provide personal TLD dosimetry for several customers outside the INP, mainly in hospitals and nuclear research institutes in Poland. We also calibrate radiation protection instruments for customers in the south of Poland. In 1999 we completed our calibration laboratory for radiation protection instruments, which is now equipped with an 85 MBq Cs-137 source, a computer-controlled automatic dosimetry bench, high-class ionisation chambers with electrometers and a dedicated database. Over 100 radiation protection monitors and dosimeters have been calibrated in the first few months of the activity of this laboratory.

    Full text: The Nuclear Energy Peruvian Institute (IPEN) has laboratories which offer services of radiological control. Radiometric analysis in raw and processed foodstuff is requested by several enterprises of both public and private sectors which uses the results for trading purposes like exportation, importation and licitations. The service of assays and calibration with reliable results has become a need due to the external audits performed by accredited laboratories to fulfil the requirements of the Peruvian standard organism. With the support of the International Atomic Energy Agency (IAEA), the IPEN laboratory of radiometric analysis implemented its quality system in 2001 under the ISO IEC 17025 Standard 'General Requirements for the Competence of the Calibration and Testing Laboratories' with the purpose to organize the activities and offer an enhanced service to the clients. The implementation of the quality system has allowed giving a better service with enhanced efficiency to the clients, assuring the reliability of the final output, the analytical results. It had been possible since the laboratories have participated in worldwide proficiency tests sponsored by the IAEA and currently work with reference material. The quality system allows identifying potential faults in any stage of the process in order to prevent any problem in the final output, assuring the appropriate quality of the issued analytical results and to take the necessary corrective actions to avoid those events to happen again. This study has identified and assessed several difficulties and troubles which prevent to fulfil the requirements of the Quality Standard and as a consequence, disable the sustainability of the quality systems and prevent the accreditation. Several proposals and solution alternatives which involve the Executive Staff and the proactive participation of the personnel are presented. (author)

    2011-03-01

    Full Text Available Biomedical science is a sensitive discipline and presents unique challenges due to its social character, continuous development and competitiveness. The issue of quality management systems and accreditation is gaining increasing interest in this sector. All over Europe, Health Services Units have started to introduce quality management systems and harmonization of criteria for accreditation is of increasing importance. Moreover, clinical laboratories, like the Assisted Reproduction laboratories and biochemical laboratories are required to apply a Quality Management System in order to ensure their correct, scientific and effective operation. Ultimately, it is a moral obligation for every health care organisation to supply the best possible care for the patient. The specific features and the diversity of clinical laboratories led to the introduction (2003 and, recently to the revision (2007 of the international standard ISO 15189, which is the first international standard developed specifically to address the requirements for accreditation of this type of laboratory. The basic principles for the quality assurance in the clinical laboratories are: x Complete and unambiguous standardized operating procedures. x Complete and unambiguous directives of operation. x Obligatory detailed written documentation, i.e., how each action is done, who will do it, where will this action take place and when. x Suitable scheduling of calibration/control/preventive maintenance of laboratory equipment and recording of each activity. x Distribution of responsibilities among the staff and continuous education and briefing according to current scientific data. x Complete and informed record file keeping. x Continuous improvement which is monitored with the adoption of quantified indicators. x Internal and external audit of all activities. x Troubleshooting. All these principles should be supported by the Management in order that the necessary adaptations should be made

  9. From misconception to a must. The measured merits of total quality management and accreditation in INAA

    International Nuclear Information System (INIS)

    Increasingly governmental bodies and industry require that supporting analytical laboratories have their quality assurance program implemented in a quality system by international standards such as derived from the ISO-25 guide. Neutron activation analysis (NAA) laboratories may have to deal with this trend too. In universities and research laboratories the need for it, and the implications of total quality management system are sometimes misconceived by unfamiliarity with the issue. The laboratory for INAA in Delft has been accredited for its quality system since 1993. Some of the tangible improvements since the introduction of quality management are presented. Four strategical considerations are given to consider the introduction of quality management at NAA laboratories, viz. with respect to the role of NAA for the validation of other methods, the role of NAA in the certification of reference materials, the preservation of knowledge and the acceptance of NAA as a respectable method.

  12. Accreditation - establishment of a quality management system in the coordinating office for the surveillance of the environmental radioactivity in soil, vegetation, fodder and foodstuffs of plant and animal origin

    International Nuclear Information System (INIS)

    The coordinating office for the surveillance of the radioactivity in the environment at the Federal Dairy Research Centre (BAfM) in Kiel/Germany is one of 7 laboratories of the BAfM which is to be accredited according to DIN EN ISO/IEC 17025. The preparation of documents needed for accreditation as well as the implementation of technical requirements stipulated in the DIN standard are about to be completed in the coordinating office. In the summer of 2003, the first review of the quality management system will be carried out by internal audits. After a subsequent test period the first audit by the accreditation body will be carried out in October 2003. The most important advantage that will arise from accreditation is that an independent party (national accreditation body AKS, Hannover/Germany) formally certifies the competence of the coordinating office to generate technically valid results. This may increase the confidence that those results that are transmitted to a third party, e.g. within one of the measurement programmes established and carried out by the coordinating office, have been generated in accordance to validated analytical methods within a certified quality management system. Furthermore, a quality management system will help to improve the quality of laboratory work with respect to a comprehensive traceability of all results obtained. Methods to be accredited include procedures for determining gamma- and beta-emitting radionuclides in those sample types for which the coordinating office in Kiel has responsibility. The methods described in the ''Messanleitungen fuer die Ueberwachung der Radioaktivitaet in der Umwelt und zur Erfassung radioaktiver Emissionen aus kerntechnischen Anlagen'' serve as a basis for the choice of methods to be accredited. As the coordinating office also conducts interlaboratory comparison studies, an increased acceptance by German and foreign laboratories may arise from the accredited status.

    2013-07-01

    Full Text Available Academic accreditation of degree programs is becoming an important mean for many institutions to improve the quality of their degree programs. Many programs, in particular computing and engineering, offered by many schools have engaged in the accreditation process with different accreditation bodies. The most known accreditation body in the Unites States of America for engineering, computing, technology, and applied science programs is ABET (Accreditation Board for Engineering and Technology. A key problem towards the satisfaction of ABET accreditation criteria is the appropriate definition and assessment of program educational objectives for a specific degree program. Program Educational Objectives are important as they represent the ultimate mean to judge the quality of a program. They related directly to student outcomes and curriculum of a degree program. We propose a set of guidelines to help understand how program educational objectives can be defined and assessed. We relate and use examples from our practical experience acquired while working on the ABET accreditation of a Software Engineering program;

  18. Challenges for academic accreditation: the UK experience

    Science.gov (United States)

    Shearman, Richard; Seddon, Deborah

    2010-08-01

    Several factors (government policy, demographic trends, employer pressure) are leading to new forms of degree programmes in UK universities. The government is strongly encouraging engagement between universities and employers. Work-based learning is increasingly found in first and second cycle programmes, along with modules designed by employers and increasing use of distance learning. Engineering faculties are playing a leading part in these developments, and the Engineering Council, the engineering professional bodies and some universities are collaborating to develop work-based learning programmes as a pathway to professional qualification. While potentially beneficial to the engineering profession, these developments pose a challenge to traditional approaches to programme accreditation. This paper explores how this system deals with these challenges and highlights the issues that will have to be addressed to ensure that the system can cope effectively with change, especially the development of individually tailored, work-based second cycle programmes, while maintaining appropriate standards and international confidence.

    The mission of the Federation of European Societies of Clinical Chemistry is to support and promote clinical chemistry and laboratory medicine in Europe, to aid communication between the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) and National Scientific Societies, to develop education and quality in the discipline, and to encourage young scientists to take an active role in these activities. One recent initiative of the Federation was a survey on accreditation of medical laboratories and training in laboratory medicine in Europe. Among European countries, three promote accreditation according to EN 45001, several countries apply systems based on professional and nationally defined standards (e.g. CPA in the UK) and other countries are moving to define accreditation standards at a national level. Data on vocational training demonstrate that this is based on a postgraduate education with duration ranging from 6 months to 11 years; in most countries the average length of university education is 5 years and that of postgraduate training is 4 years. A great difference, moreover, exists regarding the polyvalent versus monovalent training. Taken together, these data indicate that a great effort should be made by the Federation for promoting harmonization and coordination in Europe. PMID:11438289

    2010-05-01

    During the 20th century understanding for quality has changed and international and national requirements for quality have been published. Therefore also medical branches started to establish quality management systems. Quality assurance has always been important for medical laboratories. Certification according to the standard ISO 9001 and accreditation according to the standard ISO 17025 have been the proof of fulfilling quality requirements. The relatively new standard ISO 15189 is the first standard for medical laboratories. This standard includes technical and management requirements for the medical laboratory. The main focus is the proof of competence within the personnel. As this standard is accepted throughout the European Union an increase in accreditations of medical laboratories is predictable.

  6. Calibration of low-energy electron beams from a mobile linear accelerator with plane-parallel chambers using both TG-51 and TG-21 protocols

    International Nuclear Information System (INIS)

    A new approach to intraoperative radiation therapy led to the development of mobile linear electron accelerators that provide lower electron energy beams than the usual conventional accelerators commonly encountered in radiotherapy. Such mobile electron accelerators produce electron beams that have nominal energies of 4, 6, 9 and 12 MeV. This work compares the absorbed dose output calibrations using both the AAPM TG-51 and TG-21 dose calibration protocols for two types of ion chambers: a plane-parallel (PP) ionization chamber and a cylindrical ionization chamber. Our results indicate that the use of a 'Markus' PP chamber causes 2-3% overestimation in dose-output determination if accredited dosimetry-calibration laboratory based chamber factors are used. However, if the ionization chamber factors are derived using a cross-comparison at a high-energy electron beam, then a good agreement is obtained (within 1%) with a calibrated cylindrical chamber over the entire energy range down to 4 MeV. Furthermore, even though the TG-51 does not recommend using cylindrical chambers at the low energies, our results show that the cylindrical chamber has a good agreement with the PP chamber not only at 6 MeV but also down to 4 MeV electron beams.

    Science.gov (United States)

    Azila, N M A; Tan, C P L

    2005-08-01

    Accreditation is a process by which official accrediting bodies evaluate institutions using a set of criteria and standards, following established procedures, to ensure a high quality of education needed to produce highly competent graduates. Additional objectives include (1) ensuring quality institutional functioning, (2) strengthening capabilities of educational institutions for service to the nation and (3) improving public confidence in medical schools. The accreditation process provides an opportunity for the institution to critically reflect upon all the aspects of its programme and the level of compliance or attainment of the requirements. The self-evaluation exercise, which identifies strengths and weaknesses, is perceived as formative. It is envisaged that eventually institutions will adopt a learning culture for curriculum development, implementation, monitoring and matching the outcomes. In conclusion, periodic accreditation activities can act as a "monitoring" system to ensure that the quality of medical education is maintained according to established standards. PMID:16315622

  16. Automated Calibration of Dosimeters for Diagnostic Radiology

    International Nuclear Information System (INIS)

    Calibration of dosimeters for diagnostic radiology includes current and charge measurements, which are often repetitive. However, these measurements are usually done using modern electrometers, which are equipped with an RS-232 interface that enables instrument control from a computer. This paper presents an automated system aimed to the measurements for the calibration of dosimeters used in diagnostic radiology. A software application was developed, in order to achieve the acquisition of the electric charge readings, measured values of the monitor chamber, calculation of the calibration coefficient and issue of a calibration certificate. A primary data record file is filled and stored in the computer hard disk. The calibration method used was calibration by substitution. With this system, a better control over the calibration process is achieved and the need for human intervention is reduced. the automated system will be used in the calibration of dosimeters for diagnostic radiology at the Cuban Secondary Standard Dosimetry Laboratory of the Center for Radiation Protection and Hygiene.

    2015-12-01

    Full Text Available Aim: The aim of this paper is to investigate the history of accreditation of academic public health education and understand why there is a 65 year gap between the first system in America and the uptake of accreditation in Europe. The paper intends to search for parallels and dissimilarities between the development in America and Europe and then consider if any parallels could be used for determining the future role of accreditation in Europe. Methods: The paper draws heavily upon a literature review and analysis and the examination and interpretation of primary and secondary sources. Firstly there is an exploration of the American development which is complemented by an evaluation of the developments in Europe. Results: The paper demonstrates that there are two key features required for the development of accreditation: interstate collaboration and a liberalisation or opening up of the education market. Conclusions: Since the Second World War, Europe has embraced interstate collaboration which has led to a liberalisation of certain economic markets. The future for sector based accreditation of public health education will be determined by the extent Europe pursues liberalisation and whether a competitive environment will bring into question the transparency and trust in state sponsored accreditation agencies.

    Science.gov (United States)

    Cabaleiro, Joe

    2008-01-01

    Before a compounding pharmacy can receive accreditation from the Pharmacy Compounding Accreditation Board, the pharmacy must show evidence of both quality assurance activities and continuous quality improvement activities. Although quality assurance data gathering and monitoring can be integrated into pharmacy activities fairly easily, the coninuous quality improvement program may take a little more time and effort to implement . Before integrating these programs, compounding pharmacists must have a complete understanding of the differences between these two programs. Even if accreditation with the Pharmacy Compounding Accreditation Board is not being considered, it is important that compounding pharmacies have these two programs implemented. In the long run, it will pay off in higher quality services, error prevention, and perhaps greater efficiency of pharmacy operations. PMID:23969712

  1. Calibration of nuclear medicine gamma counters

    International Nuclear Information System (INIS)

    In this paper the practical problem of nuclear medicine gamma counters calibration has been solved by using dose calibrators CRC-15R with standard error ±5%. The samples from technetium generators have been measured both by dose calibrators CRC-15R and gamma counter ICN Gamma 3.33 taking into account decay correction. Only the linear part of the curve has practical meaning. The advantage of this procedure satisfies the requirements from international standards: the calibration of sources used for medical exposure be traceable to a standard dosimetry laboratory and radiopharmaceuticals for nuclear medicine procedures be calibrated in terms of activity of the radiopharmaceutical to be administered.

The ALTEA facility is an helmet-shaped device that will study concurrently the passage of cosmic radiation through the brain, the functional status of the visual system and the electrophysiological dynamics of the cortical activity. The basic instrumentation is composed by six active particle telescopes, one ElectroEncephaloGraph (EEG), a visual stimulator and a pushbutton. The telescopes are able to detect the passage of each particle measuring its energy, trajectory and released energy into the brain and identifying nuclear species. The EEG and the Visual Stimulator are able to measure the functional status of the visual system, the cortical electrophysiological activity, and to look for a correlation between incident particles, brain activity and Light Flash perceptions. These basic instruments can be used separately or in any combination, permitting several different experiments. ALTEA is scheduled to fly in the International Space Station (ISS) in November, 15th 2004. In this paper the calibration of the Flight Model of the silicon telescopes (Silicon Detector Units - SDUs) will be shown. These measures have been taken at the GSI heavy ion accelerator in Darmstadt. First calibration has been taken out in November 2003 on the SDU-FM1 using C nuclei at different energies: 100, 150, 400 and 600 Mev/n. We performed a complete beam scan of the SDU-FM1 to check functionality and homogeneity of all strips of silicon detector planes, for each beam energy we collected data to achieve good statistics and finally we put two different thickness of Aluminium and Plexiglas in front of the detector in order to study fragmentations. This test has been carried out with a Test Equipment to simulate the Digital Acquisition Unit (DAU). We are scheduled to

  6. Quality management system at the Agency's Laboratories in Seibersdorf and Vienna (RIAL)

    International Nuclear Information System (INIS)

    Confidence in product quality, in the quality and competence of the manufacturer and in the quality of testing and calibration laboratories is a prerequisite for mutual recognition between producers and customers both within a country and between different countries. This confidence is necessary not only for economic and commercial reasons but nowadays is also the basis of the acceptance and credibility of new scientific and technological developments. Traceability of measurements and calibrations to basic SI units with accompanying uncertainty, traceability of data and data comparability, as required by quality standards, must therefore also be the essential ingredients of good science in any laboratory. The best way for a laboratory to formally demonstrate its quality, i.e. conformity with quality standards, is to be accredited or certified with respect to its entire range of activities. In the case of the Agency's Laboratories at Seibersdorf and Vienna (RIAL), which belong to a large 'non-profit' international organization such as the IAEA, in addition to the reasons mentioned above one has to consider that RIAL has the additional and internationally very visible role of transferring nuclear techniques and know-how, training scientists, performing measurements and calibrations, and distributing its own products on a worldwide scale. Therefore, RIAL also has to serve as a model laboratory for the Agency's Member States in quality management in its fields of operation. For all these reasons the decision was taken to establish a formal quality system at RLKL. In consideration of the wide range of tasks performed in different fields, the ISO standard 9001 was selected as the one to be followed in the establishment of the quality system. The approach and actions undertaken by RIAL to comply with internationally recognized quality requirements are described in the paper. (author)

  8. International Accreditation of ASME Codes and Standards

    International Nuclear Information System (INIS)

    ASME established a Boiler Code Committee to develop rules for the design, fabrication and inspection of boilers. This year we recognize 75 years of that Code and will publish a history of that 75 years. The first Code and subsequent editions provided for a Code Symbol Stamp or mark which could be affixed by a manufacturer to a newly constructed product to certify that the manufacturer had designed, fabricated and had inspected it in accordance with Code requirements. The purpose of the ASME Mark is to identify those boilers that meet ASME Boiler and Pressure Vessel Code requirements. Through thousands of updates over the years, the Code has been revised to reflect technological advances and changing safety needs. Its scope has been broadened from boilers to include pressure vessels, nuclear components and systems. Proposed revisions to the Code are published for public review and comment four times per year and revisions and interpretations are published annually; it's a living and constantly evolving Code. You and your organizations are a vital part of the feedback system that keeps the Code alive. Because of this dynamic Code, we no longer have columns in newspapers listing boiler explosions. Nevertheless, it has been argued recently that ASME should go further in internationalizing its Code. Specifically, representatives of several countries, have suggested that ASME delegate to them responsibility for Code implementation within their national boundaries. The question is, thus, posed: Has the time come to franchise responsibility for administration of ASME's Code accreditation programs to foreign entities or, perhaps, 'institutes.' And if so, how should this be accomplished?

  9. Dosimetry and Calibration Section

    International Nuclear Information System (INIS)

    The two tasks of the Dosimetry and Calibration Section at CERN are the Individual Dosimetry Service which assures the personal monitoring of about 5000 persons potentially exposed to ionizing radiation at CERN, and the Calibration Laboratory which verifies all the instruments and monitors. This equipment is used by the sections of the RP Group for assuring radiation protection around CERN's accelerators, and by the Environmental Section of TISTE. In addition, nearly 250 electronic and 300 quartz fibre dosimeters, employed in operational dosimetry, are calibrated at least once a year. The Individual Dosimetry Service uses an extended database (INDOS) which contains information about all the individual doses ever received at CERN. For most of 1997 it was operated without the support of a database administrator as the technician who had assured this work retired. The Software Support Section of TIS-TE took over the technical responsibility of the database, but in view of the many other tasks of this Section and the lack of personnel, only a few interventions for solving immediate problems were possible

    2009-03-11

    U.S. Environmental Protection Agency (EPA) Performance Specification 12 in the Clean Air Mercury Rule (CAMR) states that a mercury CEM must be calibrated with National Institute for Standards and Technology (NIST)-traceable standards. In early 2009, a NIST traceable standard for elemental mercury CEM calibration still does not exist. Despite the vacature of CAMR by a Federal appeals court in early 2008, a NIST traceable standard is still needed for whatever regulation is implemented in the future. Thermo Fisher is a major vendor providing complete integrated mercury continuous emissions monitoring (CEM) systems to the industry. WRI is participating with EPA, EPRI, NIST, and Thermo Fisher towards the development of the criteria that will be used in the traceability protocols to be issued by EPA. An initial draft of an elemental mercury calibration traceability protocol was distributed for comment to the participating research groups and vendors on a limited basis in early May 2007. In August 2007, EPA issued an interim traceability protocol for elemental mercury calibrators. Various working drafts of the new interim traceability protocols were distributed in late 2008 and early 2009 to participants in the Mercury Standards Working Committee project. The protocols include sections on qualification and certification. The qualification section describes in general terms tests that must be conducted by the calibrator vendors to demonstrate that their calibration equipment meets the minimum requirements to be established by EPA for use in CAMR monitoring. Variables to be examined include linearity, ambient temperature, back pressure, ambient pressure, line voltage, and effects of shipping. None of the procedures were described in detail in the draft interim documents; however they describe what EPA would like to eventually develop. WRI is providing the data and results to EPA for use in developing revised experimental procedures and realistic acceptance criteria based on

    The Instrument Calibration Laboratory (ICL) of the Instituto de Pesquisas Energeticas e Nucleares (IPEN/CNEN-SP), Sao Paulo, SP, Brazil has developed some work in order to establish a primary standard system for low energy X-ray employing a ionization chamber of free air. For this, one of the most important steps is the determination of factors of correction of its answer. Simulation is a frequently used tool for this because some correction factors can not be determined experimentally. For the correct simulation of these correction factors is necessary some input parameters such as geometry, the material composition of the dosimeter, the experimental arrangement and the radiation source are specified correctly. For the ionization chamber available on the LCI, the geometry, the material components and the experimental arrangement can be obtained easily. On the other hand, spectrum of radiation energy source, which must be inserted into the computer code has not been obtained. Thus, this study aims to determine this radiation spectrum, thus enabling the characterization of the new primary standard for low power X-radiation of ICL.

    This is a new facility that, in keeping with the recommendations of standard ISO 8529:1, has 20m5-Be and 252Cf neutron sources stored in water inside a 9 m x 7.5 m x 8 m Irradiation Room with 1.25 m concrete walls that is accessed through a 6.5 ton sliding shielded door. These sources are remotely handled from the Control Room by means of a system that places them in the geometric center of the room and aligns them with the equipment or materials to be irradiated arranged on a base plate. The facility has a series of interlocks that guarantee safety during operations with sources, and the verification measurements have demonstrated the suitability of the shielding used. The LPN will be the answer to the demand for a national laboratory for neutron measurement equipment calibration and equipment and material irradiation under controlled conditions, and it will position our country at the same level as our European partners.

    Sinelnikov, Sergey; Friedman, Lee S; Chavez, Emily A

    2016-06-01

    Safe Communities (SC) is a global movement that brings together community stakeholders to collaboratively address injury concerns. SC accreditation is a formal process through which communities are recognized for strengthening local injury prevention capacity. Six million Americans live in 25 SC sites, but no research has been done to understand the model's potential impact on this population. This study explored the temporal relationship between SC accreditation and injury trends in three SC sites from the state of Illinois-Arlington Heights, Itasca, and New Lenox. Hospitalization data, including patient demographics, exposure information, injury outcomes, and economic variables, were obtained from a statewide hospital discharge database for a 12-year period (1999-2011). Joinpoint regression models were fitted to identify any periods of significant change, examine the direction of the injury trend, and to estimate monthly percent changes in injury counts and rates. Poisson random-intercept regression measured the average total change since the official SC accreditation for the three communities combined and compared them to three matched control sites. In joinpoint regression, one of the SC sites showed a 10-year increase in hospitalization cases and rates followed by a two-year decline, and the trend reversal occurred while the community was pursuing the SC accreditation. Injury hospitalizations decreased after accreditation compared to the pre-accreditation period when SC sites were compared to their control counterparts using Poisson modeling. Our findings suggest that the SC model may be a promising approach to reduce injuries. Further research is warranted to replicate these findings in other communities. PMID:26974025

    No consensus definition exists for postgraduate physician assistant (PA) training. This report from the AAPA Task Force on Accreditation of Postgraduate PA Training Programs describes the types of clinical training programs and their effects on hiring and compensation of PAs. Although completing a postgraduate program appears to have no effect on compensation, PAs who complete these programs may be favored in the hiring process and frequently report greater confidence in their skills. More research is needed and program accreditation is key to monitoring the effectiveness of these programs. PMID:27124222

    smoothness-constrained inversion routine. In the inversion, we applied an empirically-derived resistance error model based on normal and reciprocal measurements to obtain adequately and consistently fitted resistivity images at the different time steps. Five temperature loggers were installed at 2.5m, 5m, 10m, 15m, and 20m from the north face to validate whether imaged resistivity values match laboratory-calibrated temperature-resistivity paths. Here we discuss whether high-resolution ERT in homogeneous rock walls with (i) laboratory-calibrated temperature-resistivity behavior, (ii) an incorporated resistance error model to ensure optimum and consistent fitting of the data, and (iii) field validation with temperature logger data provides reliable, spatially- resolved subzero temperature-information in permafrost rocks.

    Calibration services for the medical community applications of radiation involve measuring radiation precisely and having traceability to the National Institute of Standards and Technology (NIST). Radiation therapy applications involve the use of ionization chambers and electrometers for external beams and well-type ionization chamber systems as well as radioactive sources for brachytherapy. Diagnostic x-ray applications involve ionization chamber systems and devices to measure other parameters of the x-ray machine, such as non-invasive kVp meters. Calibration laboratories have been established to provide radiation calibration services while maintaining traceability to NIST. New radiation applications of the medical community spur investigation to provide the future calibration needs.

    2008-12-01

    It has often been suggested in recent years that Geology programs in the USA obtain some sort of accreditation. While this discussion continues, it is worthwhile for administrators of Geology, Earth Science, and Geophysics programs to become familiar with the current practices of ABET-accredited Engineering programs, particularly those in Geological Engineering on the one hand, and with the current practices of AMS-accredited programs in Atmospheric Sciences on the other hand. The ABET and AMS approaches provide end-members for rigor and enforcement, while also covering fields of interest to those involved in Geology, Geophysics, or Earth Science. ABET, Inc. (formerly the Accreditation Board for Engineering and Technology) is a "federation of 29 professional and technical societies" and it is the members of those societies who develop practices and guidelines for the various disciplines under accreditation. In the case of Geological Engineering, the member society responsible is SME (Society for Mining, Metallurgy, and Exploration, Inc.). All Engineering programs accredited by ABET have agreed to a common core of seven criteria that must be met. Some of these criteria require each institution to have established their own educational objectives and the means by which these objectives are regularly reviewed and their success objectively assessed. The curriculum itself is not specified, although some requirements are in place regarding the minimum amount of science, math, and "engineering" coursework required. An important issue, however, is "program outcomes", some of which are in common across all engineering disciplines, while others are established (in the case of Geological Engineering) by SME. The coursework necessary to achieve these outcomes must be in place and taken by all students, and there must be an assessment mechanism in place and regularly executed to evaluate the success of learning (the "outcome"). Most engineers are required by their practice to

  13. Guidelines on calibration of neutron measuring devices

    International Nuclear Information System (INIS)

    The International Atomic Energy Agency and the World Health Organization have agreed to establish an IAEA/WHO Network of Secondary Standard Dosimetry Laboratories (SSDLs) in order to improve accuracy in applied radiation dosimetry throughout the world. These SSDLs must be equipped with, and maintain, secondary standard instruments, which have been calibrated against primary standards, and must be nominated by their governments for membership of the network. The majority of the existing SSDLs were established primarily to work with photon radiation (X-rays and gamma rays). Neutron sources are, however, increasingly being applied in industrial processes, research, nuclear power development and radiation biology and medicine. Thus, it is desirable that the SSDLs in countries using neutron sources on a regular basis should also fulfil the minimum requirements to calibrate neutron measuring devices. It is the primary purpose of this handbook to provide guidance on calibration of instruments for radiation protection. A calibration laboratory should also be in a position to calibrate instrumentation being used for the measurement of kerma and absorbed dose and their corresponding rates. This calibration is generally done with photons. In addition, since each neutron field is usually contaminated by photons produced in the source or by scatter in the surrounding media, neutron protection instrumentation has to be tested with respect to its intrinsic photon response. The laboratory will therefore need to possess equipment for photon calibration. This publication deals primarily with methods of applying radioactive neutron sources for calibration of instrumentation, and gives an indication of the space, manpower and facilities needed to fulfil the minimum requirements of a calibration laboratory for neutron work. It is intended to serve as a guide for centres about to start on neutron dosimetry standardization and calibration. 94 refs, 8 figs, 12 tabs

    Lai, Chi-Wan

    2009-01-01

    THIS REVIEW AIMS TO INTRODUCE THE TAIWANESE MEDICAL ACCREDITATION SYSTEM: its history, role and future goals. In 1999, the Ministry of Education, Taiwanese Government commissioned the non-profit National Health Research Institutes (NHRI) to develop a new medical accreditation system. According to that policy, the Taiwan Medical Accreditation Council (TMAC) was established in the same year. The council serves a similar function to that of the Liaison Committee on Medical Education (LCME) of the United States and the Australian Medical Council (AMC). The accreditation process consists of a self-assessment plus a four-day site visit by a team of eight medical educators that are headed by one of the council members of the TMAC. The first cycle of initial visits was completed from 2001 to 2004. Subsequent follow-up visits were arranged according to the results of the survey with smaller-sized teams and shorter periods. There is evidence to suggest that the majority (seven of eleven) of the medical schools in Taiwan have made good progress. TMAC's next step will be to monitor the progress and raise the standard of medical education in individual schools with a homogenous, superior standard of medical education. PMID:20046455

  13. Absolute calibration in vivo measurement systems

    International Nuclear Information System (INIS)

    Lawrence Livermore National Laboratory (LLNL) is currently investigating a new method for obtaining absolute calibration factors for radiation measurement systems used to measure internally deposited radionuclides in vivo. Absolute calibration of in vivo measurement systems will eliminate the need to generate a series of human surrogate structures (i.e., phantoms) for calibrating in vivo measurement systems. The absolute calibration of in vivo measurement systems utilizes magnetic resonance imaging (MRI) to define physiological structure, size, and composition. The MRI image provides a digitized representation of the physiological structure, which allows for any mathematical distribution of radionuclides within the body. Using Monte Carlo transport codes, the emission spectrum from the body is predicted. The in vivo measurement equipment is calibrated using the Monte Carlo code and adjusting for the intrinsic properties of the detection system. The calibration factors are verified using measurements of existing phantoms and previously obtained measurements of human volunteers. 8 refs

  16. Dosimetry and Calibration Section

    International Nuclear Information System (INIS)

    The Dosimetry and Calibration Section fulfils two tasks within CERN's Radiation Protection Group: the Individual Dosimetry Service monitors more than 5000 persons potentially exposed to ionizing radiation on the CERN sites, and the Calibration Laboratory verifies throughout the year, at regular intervals, over 1000 instruments, monitors, and electronic dosimeters used by RP Group. The establishment of a Quality Assurance System for the Individual Dosimetry Service, a requirement of the new Swiss Ordinance for personal dosimetry, put a considerable workload on the section. Together with an external consultant it was decided to identify and then describe the different 'processes' of the routine work performed in the dosimetry service. The resulting Quality Manual was submitted to the Federal Office for Public Health in Bern in autumn. The CERN Individual Dosimetry Service will eventually be officially endorsed after a successful technical test in March 1999. On the technical side, the introduction of an automatic development machine for gamma films was very successful. It processes the dosimetric films without an operator being present, and its built-in regeneration mechanism keeps the concentration of the processing chemicals at a constant level

  17. Calibration and intercomparison methods of dose calibrators used in nuclear medicine facilities

    International Nuclear Information System (INIS)

    Dose calibrators are used in most of the nuclear medicine facilities to determine the amount of radioactivity administered to a patient in a particular investigation or therapeutic procedure. It is therefore of vital importance that the equipment used presents good performance and is regular;y calibrated at a authorized laboratory. This occurs of adequate quality assurance procedures are carried out. Such quality control tests should be performed daily, other biannually or yearly, testing, for example, its accuracy and precision, the reproducibility and response linearity. In this work a commercial dose calibrator was calibrated with solution of radionuclides used in nuclear medicine. Simple instrument tests, such as response linearity and the response variation of the source volume increase at a constant source activity concentration, were performed. This instrument can now be used as a working standard for calibration of other dose calibrators/ An intercomparison procedure was proposed as a method of quality control of dose calibrators used in nuclear medicine facilities.

    Full Text Available Accreditation is usually a voluntary program, in which authorized external peer reviewers evaluate the compliance of a health care organization with pre-established performance standards. The aim of this study was to systematically review the literature of the attitude of health care professionals towards professional accreditation. A systematic search of four databases including Medline, Embase, Healthstar, and Cinhal presented seventeen studies that had evaluated the attitudes of health care professionals towards accreditation. Health care professionals had a skeptical attitude towards accreditation. Owners of hospitals indicated that accreditation had the potential of being used as a marketing tool. Health care professionals viewed accreditation programs as bureaucratic and demanding. There was consistent concern, especially in developing countries, about the cost of accreditation programs and their impact on the quality of health care services.

  1. Quality management system of secondary standards dosimetry laboratory in Sri Lanka

    International Nuclear Information System (INIS)

    Full text: Application of Quality Management System (QMS) of Secondary Standard Dosimetry Laboratory (SSDL) of the Atomic Energy Authority (ALA) of Sri Lanka provides path of workflow and information on laboratory operations, management and competence of staff that would assist the laboratory in continual improvement of its processes and meeting accreditation requirements in compliance with IS017025. Thus provision of customers' satisfied accredited dosimetry calibration services is needed for the country. The SSDL currently possesses a reference electrometer (PTW Unidos) with protection level ion- chambers (NE2575, 600cc ion-chamber and PTW - lOLt ion-chamber) and therapy level ion-chambers (NE2571, 0.6cc thimble ion-chamber). Also the laboratory is also having measuring standards (NE2570 electrometer with NE2575, 600cc ion-chamber and NE2571, 0.6cc thimble ion-chamber) . A gamma irradiator which contains two gamma sources (Co-60 and Cs-137) and a X-ray system with six ISO 4037 beam qualities (narrow spectrum of energy range: 33keV - 118keV) are available for protection level X-ray calibrations. Stability of the electrometers with Ion- chambers is performed with Sr-90 check sources, which are specially designed for each type of chambers in order to fix the set-up maintaining the same geometry for every measurement. An average of reading of ten consecutive measurements of which each measurement was made for 300s is taken for stability measurement. Each reading is corrected for ambient temperature and pressure. Acceptance of percentage deviation of stability results with respect to reference reading of respective chamber is ±1% for protection level and ± 0.5% for therapy level. All these equipments, when they are not in used are kept in a dry cabinet in order to control humidity. The SSDL of AEA has become a part of an international network of dosimetry laboratories established by the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO

    Full Text Available The essential prerequisite of radiation dosimetry is to provide quality assurance and documentation that the irradiation procedure has been carried out according to the specification requirement of correct calibration of the chosen dosimetry system. At the Radiation Plant of the Vinča Institute of Nuclear Sciences we compared two recommended protocols of irradiation procedures in the calibration of dosimetry systems in radiation processing: (1 by irradiation of routine dosimeters (ethanol-chlorobenzene - ECB at the calibration laboratory and (2, by in-plant calibration with alanine transfer - dosimeters. The critical point for in-plant calibration is irradiation geometry, so we carefully positioned the phantom carrying both dosimeters in order to minimize dose gradients across the sample. The analysis of results obtained showed that the difference among determined absorbed doses for the construction of calibration curves between these two methods, (alanine vs. ECB, is less than 1%. The difference in combined standard uncertainty for each calibration procedure is 0.1%. These results demonstrate that our in-plant calibration is as good as calibration by irradiation at the calibration laboratory and validates our placement of the irradiation phantom during irradiation.

    Background Potentially, unit-specific in-vitro calibration of accelerometers could increase field data quality and study power. However, reduced inter-unit variability would only be important if random instrument variability contributes considerably to the total variation in field data. Therefore, the primary aim of this study was to calculate and apply unit-specific calibration factors in multiple accelerometers in order to examine the impact on random output variation caused by inter-instrument variability. Methods Instrument-specific calibration factors were estimated in 25 MTI- and 53 CSA accelerometers in a mechanical setup using four different settings varying in frequencies and/or amplitudes. Calibration effect was analysed by comparing raw and calibrated data after applying unit-specific calibration factors to data obtained during quality checks in a mechanical setup and to data collected during free living conditions. Results Calibration reduced inter-instrument variability considerably in the mechanical setup, both in the MTI instruments (raw SDbetween units = 195 counts*min-1 vs. calibrated SDbetween units = 65 counts*min-1) and in the CSA instruments (raw SDbetween units = 343 counts*min-1 vs. calibrated SDbetween units = 67 counts*min-1). However, the effect of applying the derived calibration to children's and adolescents' free living physical activity data did not alter the coefficient of variation (CV) (children: CVraw = 30.2% vs. CVcalibrated = 30.4%, adolescents: CVraw = 36.3% vs. CVcalibrated = 35.7%). High correlations (r = 0.99 & r = 0.98, respectively) were observed between raw and calibrated field data, and the proportion of the total variation caused by the MTI- and CSA monitor was estimated to be only 1.1% and 4.2%, respectively. Compared to the CSA instruments, a significantly increased (9.95%) mean acceleration response was observed post hoc in the batch of MTI instruments, in which a significantly reduced inter-instrumental reliability

    Environmental engineers respond to the challenges posed by a growing population, intensifying land-use pressures, natural resources exploitation as well as rapidly evolving technology. The environmental engineer must develop technically sound solutions within the framework of maintaining or improving environmental quality, complying with public policy, and optimizing the utilization of resources. The engineer provides system and component design, serves as a technical advisor in policy making and legal deliberations, develops management schemes for resources, and provides technical evaluations of systems. Through the current work of environmental engineers, individuals and businesses are able to understand how to coordinate society's interaction with the environment. There will always be a need for engineers who are able to integrate the latest technologies into systems to respond to the needs for food and energy while protecting natural resources. In general, the environment-related challenges and problems need to be faced at global level, leading to the globalization of the engineering profession which requires not only the capacity to communicate in a common technical language, but also the assurance of an adequate and common level of technical competences, knowledge and understanding. In this framework, the Europe-based EUR ACE (European Accreditation of Engineering Programmes) system, currently operated by ENAEE - European Network for Accreditation of Engineering Education can represent the proper framework and accreditation system in order to provide a set of measures to assess the quality of engineering degree programmes in Europe and abroad. The application of the accreditation model EUR-ACE, and of the National Italian Degree Courses Accreditation System, promoted by the Italian National Agency for the Evaluation of Universities and Research Institutes (ANVUR), to the Environmental Engineering Degree Courses at the University of Firenze is presented.

    Full Text Available The article deals with the Hospital Accreditation as a quality parameter of hospitals in Brazil and the world. The focus was to identify how the hospitals of the host cities of the FIFA World Cup in 2014 are classified by the National Accreditation Organization (ONA and Joint Commission on Accreditation of Hospitals (JCI - the Brazilian Consortium for Accreditation (CBA. The Brazilian Manual of Accreditation establishes three stamps of hospital quality: Level 1: Accredited, Level 2: Fully Accredited and Level 3: Accredited with Excellence. From the methodological point of view the study was regarded as an exploratory approach, with a kind psychographic survey, with the intentional collection of data, ie the host cities. The research had a qualitative and quantitative treatment. Data were collected during March and April 2011 through the official websites of the ONA, JCI-CBA and FIFA on the Internet. It was concluded that the cities of Sao Paulo, Rio de Janeiro and Belo Horizonte are the best prepared in time for hospital accreditation by ONA and / or JCI-CBA. The hospitals of other offices need to create mechanisms to achieve a quality accreditation of types urgently. Only thus will avoid the negative image of the Brazilian health services to foreigners who, by bad luck, requiring medical and hospital during the World Cup 2014.

  9. The Emergence of Hospital Accreditation Programs in East Africa: Lessons from Uganda, Kenya, and Tanzania

    2014-03-01

    Full Text Available The objective of this manuscript was to examine existing hospital accreditation systems in three East African countries (Uganda, Kenya and Tanzania, assess attitudes and opinions of key stakeholders regarding hospital accreditation systems in the region, and identify lessons regarding sustainable and effective implementation of hospital accreditation systems in resource-limited countries. National hospital accreditation systems were found in Kenya and Tanzania. Uganda’s accreditation system, known as Yellow Star, had been suspended. Attitudes and opinions of key stakeholders almost unanimously supported the idea of establishing new national hospital accreditation programs, but opinions differed regarding whether that system should be operated by the government or a private independent organization. Our analysis supports the following lessons regarding accreditation systems in the region: (1 self--‐funding mechanisms are critical to long-term success; (2 external assessments occurred more frequently in our focus countries than accreditation systems in developed countries; (3 Kenya has established framework for providing financial incentives to highly performing hospitals, but these links need to be strengthened; and (4 automatic accreditation of governmental health facilities in Kenya and Tanzania illustrate the potential hazard of public authorities overseeing accreditation programs.

  10. Accreditation self-evaluation: an effective program evaluation tool

    International Nuclear Information System (INIS)

    The Institute of Nuclear Power Operation's (INPO) Accreditation Program includes a systematic evaluation that subsequently improves nuclear utility training programs. The process begins with a utility-conducted self-evaluation that measures its training programs against the accreditation criteria and objectives. When properly conducted, the self-evaluation results should identify weaknesses within each program as well as program strengths. Utilities are then expected to take the necessary actions to correct the weaknesses that have been found. Experience with the process has shown that a properly conducted self-evaluation can also be an effective program evaluation. In addition, much of the data and information that are collected and used during the self-evaluation process are also used in conducting other evaluations of the training organization and programs. This paper will discuss using the self-evaluation process as a tool for conducting program evaluations

  19. Audit experience in external individual monitoring services accreditation in Brazil

    International Nuclear Information System (INIS)

    Brazilian Nuclear Energy Commission (CNEN) has been carrying out an accreditation program for the External Individual Monitoring Services (named SMIE) for about 45.000 workers involved with ionizing radiation. One of this steps of this accreditation program is the audit to each SMIE. The main audit objective is to verify and to check organizational documentation, system performance test, technical personnel ability and training, quality assurance system procedures and records, essential equipment and facilities and reliability of dose reports. In order to avoid a different audit for each SMIE, effort were made to obtain a standard process. Two aspects were considered the most relevant ones: human resources training and audit procedures. To achieve the first one, a practical and theoretical course taking into account auditing needs was elaborated. As well as experience in one of the technical related areas, an important condition to be member of an audit team is to obtain satisfactory approval in one of the offered courses. In order to accomplish the second point, a set of documents was implemented such as an audit checklist, audit report models, and procedures and recommendations to audit. Up to February 1998, 12 accreditation audits were performed. The main points of this program as well as an assessment of its difficulties and success are reported in this work

  20. Social accountability of medical education: aspects on global accreditation.

    Science.gov (United States)

    Lindgren, Stefan; Karle, Hans

    2011-01-01

    Medical doctors constitute a profession which embraces trust from and accountability to society. This responsibility extends to all medical educational institutions. Social accountability of medical education means a willingness and ability to adjust to the needs of patients and health care systems both nationally and globally. But it also implies a responsibility to contribute to the development of medicine and society through fostering competence for research and improvement. Accreditation is a process by which a statutory body evaluates and recognises an educational institution and/or its programme with respect to meeting approved criteria. It is a means for quality assurance, but also a strong power to reinforce the need for improvement and reforms. It must be performed through internationally recognised and transparent standards and should foremost promote quality development. The social accountability of medical education must be included in all accreditation processes at all levels. The global standards programme by World Federation for Medical Education (WFME) provides tools for national or regional accreditation but also guidance for reforms and quality improvement. The standards are used worldwide and have been adopted to local needs in most parts of the world. They are framed to specify attainment at two levels: basic standards or minimum requirements and standards for quality development. The concept of social accountability is embedded in all parts of the WFME standards documents. In 2011, a revision of the standards for undergraduate education has been instituted. Strengthening of aspects on social accountability of medical education will be a particular concern. PMID:21774655

  1. Absolute sensitivity calibration of extreme ultraviolet photoresists

    Jones, Juanita; Naulleau, Patrick P.; Gullikson, Eric M.; Aquila, Andrew; George, Simi; Niakoula, Dimitra

    2008-05-16

    One of the major challenges facing the commercialization of extreme ultraviolet (EUV) lithography remains simultaneously achieving resist sensitivity, line-edge roughness, and resolution requirement. Sensitivity is of particular concern owing to its direct impact on source power requirements. Most current EUV exposure tools have been calibrated against a resist standard with the actual calibration of the standard resist dating back to EUV exposures at Sandia National Laboratories in the mid 1990s. Here they report on an independent sensitivity calibration of two baseline resists from the SEMATECH Berkeley MET tool performed at the Advanced Light Source Calibrations and Standards beamline. The results show the baseline resists to be approximately 1.9 times faster than previously thought based on calibration against the long standing resist standard.

  2. Trinocular Calibration Method Based on Binocular Calibration

    2012-10-01

    Full Text Available In order to solve the self-occlusion problem in plane-based multi-camera calibration system and expand the measurement range, a tri-camera vision system based on binocular calibration is proposed. The three cameras are grouped into two pairs, while the public camera is taken as the reference to build the global coordinate. By calibration of the measured absolute distance and the true absolute distance, global calibration is realized. The MRE (mean relative error of the global calibration of the two camera pairs in the experiments can be as low as 0.277% and 0.328% respectively. Experiment results show that this method is feasible, simple and effective, and has high precision.

  3. Which Phantom Is Better for Assessing the Image Quality in Full-Field Digital Mammography?: American College of Radiology Accreditation Phantom versus Digital Mammography Accreditation Phantom

    International Nuclear Information System (INIS)

    To compare between the American College of Radiology (ACR) accreditation phantom and digital mammography accreditation phantom in assessing the image quality in full-field digital mammography (FFDM). In each week throughout the 42-week study, we obtained phantom images using both the ACR accreditation phantom and the digital mammography accreditation phantom, and a total of 42 pairs of images were included in this study. We assessed the signal-to-noise ratio (SNR) in each phantom image. A radiologist drew a square-shaped region of interest on the phantom and then the mean value of the SNR and the standard deviation were automatically provided on a monitor. SNR was calculated by an equation, measured mean value of SNR-constant coefficient of FFDM/standard deviation. Two breast radiologists scored visible objects (fibers, specks, and masses) with soft-copy images and calculated the visible rate (number of visible objects/total number of objects). We compared SNR and the visible rate of objects between the two phantoms and calculated the k-coefficient for interobserver agreement. The SNR of the ACR accreditation phantom ranged from 42.0 to 52.9 (Mean, 47.3 ± 2.79) and that of Digital Phantom ranged from 24.8 to 54.0 (Mean, 44.1 ± 9.93) (p = 0.028). The visible rates of all three types of objects were much higher in the ACR accreditation phantom than those in the digital mammography accreditation phantom (p < 0.05). Interobserver agreement for visible rates of objects on phantom images was fair to moderate agreement (k-coefficients: 0.34-0.57). The ACR accreditation phantom is superior to the digital mammography accreditation phantom in terms of SNR and visibility of phantom objects. Thus, ACR accreditation phantom appears to be satisfactory for assessing the image quality in FFDM.

    Chen, Siqi; Cheng, Yang; Willson, Reg

    2006-01-01

    Automated Camera Calibration (ACAL) is a computer program that automates the generation of calibration data for camera models used in machine vision systems. Machine vision camera models describe the mapping between points in three-dimensional (3D) space in front of the camera and the corresponding points in two-dimensional (2D) space in the camera s image. Calibrating a camera model requires a set of calibration data containing known 3D-to-2D point correspondences for the given camera system. Generating calibration data typically involves taking images of a calibration target where the 3D locations of the target s fiducial marks are known, and then measuring the 2D locations of the fiducial marks in the images. ACAL automates the analysis of calibration target images and greatly speeds the overall calibration process.

  9. Design and development of source holder of collimator assembly for low level radiological testing and calibration

    International Nuclear Information System (INIS)

    The low level radiological test and calibration facility under ISO: 17025; NABL accreditation has been recently upgraded in terms of radiation source strength and radiation collimation geometry. The decayed cobalt-60 radiation source (2.3 mCi) has been replenished with new radioactive source of activity 10 mCi. The source was procured from BRIT Mumbai with physical dimension 15 mm (L) x 10 mm (f), however, the active geometry of the source was not known. An autoradiography concept was applied to know the exact geometry of active dimension of the source with respect to its physical dimension. The source was immobilized on the industrial radiography film and exposed with X-rays (KV: 100, mA: 1, t: 0.5 s) at 100 cm from focal point of X-ray tube. The film was developed under standard laboratory condition in the dark room. The radioactive pellet has been found well delineated with respect to the physical dimension of the source inside the capsule. The exact physical dimension of the source and active dimension have been found as 9 mm (L) x 8 mm (f) and 3 mm (L) x 2 mm (f) respectively. A source holder of perspex material was designed and fabricated as per collimator geometry, ease of fitment and divergence profile of radiation beam. The autoradiography procedure (KV: 70, mA: 1, t: 0.7 s) was repeated after fixing the source in fabricated perpex holder for checking the quality of the immobilization of source in the holder. An improvement in positioning error (±5 mm) while testing and calibrating the radiological instruments, has been observed with the help of autoradiograph. The alignment of the source was checked and verified with laser alignment system. The designed collimator is made of tissue equivalent material and hence will have less radiation scattering. The radiological calibration facility is now more efficient in terms of systematic measurement uncertainty. This has improved the quality standard of the radiological test and calibration.

    A goal of an imaging accreditation program is to ensure adequate image quality, verify appropriate staff qualifications, and to assure patient and personnel safety. Currently, more than 35,000 facilities in 10 modalities have been accredited by the American College of Radiology (ACR), making the ACR program one of the most prolific accreditation options in the U.S. In addition, the ACR is one of the accepted accreditations required by some state laws, CMS/MIPPA insurance and others. Familiarity with the ACR accreditation process is therefore essential to clinical diagnostic medical physicists. Maintaining sufficient knowledge of the ACR program must include keeping up-to-date as the various modality requirements are refined to better serve the goals of the program and to accommodate newer technologies and practices. This session consists of presentations from authorities in four ACR accreditation modality programs, including magnetic resonance imaging, mammography, ultrasound, and computed tomography. Each speaker will discuss the general components of the modality program and address any recent changes to the requirements. Learning Objectives: To understand the requirements of the ACR MR accreditation program. The discussion will include accreditation of whole-body general purpose magnets, dedicated extremity systems well as breast MRI accreditation.
