    UV radiation is responsible for the induction of epithelial and melanocytic skin cancer, photoaging, and photodermatoses. UV protection is necessary to prevent damage caused by non-physiologic exposure. UV protection includes not only reduction of sun exposure but also use of sun protective filters, UV protective clothes, DNA repair enzymes, and antioxidant supplementation. Consumers are uncertain about the possibilities and limitations of commercial sun protection measures. Dermatologists must explain protective measures to the general public which continues to believe that UV-tanned skin is healthy. The sunscreen market is a highly competitive but lucrative market. The range of products with different designations and promises makes difficult for both consumers and dermatologists to determine what is sensible UV protection.

    Assigned protection factor (APF) is an indicator representing effectiveness of a respirator and it provides workplace level of respiratory protection for workers in providing protection against exposure to airborne contaminants Occupational Safety and Health Administration (OSHA) specifies 'Respirator APF' and 'Maximum Use Concentration' (MUC - a term derived using APF) shall be an integral part of Respirator Protection Standard. MUC establishes the maximum airborne concentration of a contaminant in which a respirator with a given APF may be used. The use of particulate respirators such as half face mask, full face mask and powered air purifying respirators is essential for radioactive jobs in nuclear facilities to prevent any intake of radionuclide. With this impetus, the Protection Factor Test Facility (PFTF) for testing and evaluation of respiratory protective equipment meeting relevant applicable standards was designed, fabricated and installed in Respiratory Protective Equipment Laboratory of Health Physics Division

    Ch'ng, Joanne W M; Glendon, A Ian

    2014-04-01

    Protection motivation theory components were used to predict sun protection behaviors (SPBs) using four outcome measures: typical reported behaviors, previous reported behaviors, current sunscreen use as determined by interview, and current observed behaviors (clothing worn) to control for common method bias. Sampled from two SE Queensland public beaches during summer, 199 participants aged 18-29 years completed a questionnaire measuring perceived severity, perceived vulnerability, response efficacy, response costs, and protection motivation (PM). Personal perceived risk (similar to threat appraisal) and response likelihood (similar to coping appraisal) were derived from their respective PM components. Protection motivation predicted all four SPB criterion variables. Personal perceived risk and response likelihood predicted protection motivation. Protection motivation completely mediated the effect of response likelihood on all four criterion variables. Alternative models are considered. Strengths and limitations of the study are outlined and suggestions made for future research.

  10. PROTECTION OF WORKS TITLES FROM THE PERSPECTIVE OF COPYRIGHT PROTECTION AND TRADEMARK PROTECTION

    Directory of Open Access Journals (Sweden)

    George-Mihai IRIMESCU

    2017-05-01

    Full Text Available The main purpose of the paper is assessing the possibilities of protecting the titles of works. One possibility is the protection by means of registered or unregistered trademarks. This route presents difficulties because of the distinctiveness perspective. In this sense, the European case-law has recently developed a constant practice and outlined a series of criteria that should be taken into consideration when examining a trademark consisting of a title. Another possibility is protecting the title under the provisions of the copyright law. From this respect, the practice has not yet determined a constant practice. However, the dominant opinion is that the originality criterion should be taken into consideration when assessing the protection of a tile. Finally, brief conclusion are made, including short remarks on the cumulative protection of titles, both as trademarks and under the copyright law.

  11. Designing physical protection technology for insider protection

    International Nuclear Information System (INIS)

    Trujillo, A.A.; Waddoups, I.G.

    1986-01-01

    Since its inception, the nuclear industry has been engaged in providing protection against an insider threat. Although insider protection activities have been fairly successful in the past, present societal conditions require increased protection to further minimize the existence of an insider or the consequences of an insider-perpetrated incident. Integration of insider protection techniques into existing administrative and operational procedures has resulted in economic and operational impacts. Future increases in insider protection may result in even greater impacts, so we must proceed wisely as new approaches are developed. Increased emphasis on background investigations, security clearances, human reliability programs, security awareness activities, and the development of technology to address the insider threat are evidence of continuing concern in this area. Experience ranging from operational test and evaluation of developmental equipment to conceptual designs for new facilities has led to the development of general principles and conclusions for mitigating the insider threat while minimizing adverse impacts on site operations. Important principles include real-time monitoring of personnel and material and requiring that the physical protection and material control and accounting systems to be much more coordinated and integrated than in the past

  13. Environmental protection: Shifting the focus toward the protected object

    Directory of Open Access Journals (Sweden)

    Cvetić Radenka

    2013-01-01

    Full Text Available This article is an attempt to provide a comprehensive overview of the rationale which led to developments in the law of environmental protection in a direction of an even more efficient protection of environment from human beings. There has been a transformation of the constitutionally protected right to a healthy environment to the Constitutional guarantee which involves both duty and responsibility for its protection. There has also been a shift from declaratory protection toward enforceable prohibitions and orders. These transformations have occurred when the society faced, under dramatic circumstances, the situation which shows that failure to protect the common good could lead to catastrophic consequences. The system of environmental protection, which enables sustainable development, is based on the primacy of the precautionary principle which deals with prevention and reduction of probability of harm, as well as on the no fault liability of the polluter for the environmental harm even in the absence of the claim for damages. The efficacy of the environmental protection could be improved by raising the awareness of the preservation of environment. The understanding that the protection of environment amounts to a survival of a mankind could lead to creating rights for the environment as such.

    This article addresses climate-tipping points in the Amazon Basin resulting from deforestation. It applies a regional climate model to assess whether the system of protected areas in Brazil is able to avoid such tipping points, with massive conversion to semiarid vegetation, particularly along the south and southeastern margins of the basin. The regional climate model produces spatially distributed annual rainfall under a variety of external forcing conditions, assuming that all land outside protected areas is deforested. It translates these results into dry season impacts on resident ecosystems and shows that Amazonian dry ecosystems in the southern and southeastern basin do not desiccate appreciably and that extensive areas experience an increase in precipitation. Nor do the moist forests dry out to an excessive amount. Evidently, Brazilian environmental policy has created a sustainable core of protected areas in the Amazon that buffers against potential climate-tipping points and protects the drier ecosystems of the basin. Thus, all efforts should be made to manage them effectively. PMID:19549819

  19. To protect or not to protect: examining reasons for sun protection among young women at risk for skin cancer.

    Science.gov (United States)

    Auerbach, M V; Heckman, C J; Darlow, S

    2018-03-27

    We aimed to further the understanding of the low rates of sun protection in young women at risk for skin cancer. Six-hundred-sixty-one daily diary entries were received via text message over 14 days from 56 young women at moderate to high risk of developing skin cancer. Women reported whether or not they used sun protection and also listed what their reasons were for using protection or not using sun protection each day. Multi-level modeling was used to examine the influence of study variables when predicting daily sun protection or lack of protection. The number of days in which sun protection was reported was positively associated with "habit" and "prevention" as reasons for protection and negatively associated with "not-needed" and "unprepared" as reasons for non-protection. Self-reported sun protection increased over the 14-day study period. Results of this study suggest the potential value of interventions aimed at motives for sun-protection behaviors.

  20. Field selection of chemical protective clothing and respiratory protection

    Pinette, S.; Dodgen, C.; Morley, M.

    1991-01-01

    Safety professionals who must choose appropriate personal protective equipment for hazardous substance response or hazardous waste sites require useable information about the effectiveness of the various products available. Each hazardous waste operation involves a unique combination of chemical hazards requiring a unique combination of protective apparel. A chemical protective suit or respirator must be chosen for each site and each operation on the site. No single protective suit is effective against all chemical hazards. No single respirator is the best choice in every situation. Various sources of information on the effectiveness of protective clothing products will be discussed. Site-specific permeation testing of the proposed protective clothing options will also be discussed. It is both possible and practical to obtain specific information about the degree of protection afforded by a particular suit against a particular chemical mixture. It is also important to know how long the suit will last. Choosing adequate respiratory protection is a complex process. Respirator cartridge performance depends on various environmental factors as well as upon the combination and concentration of chemicals in the air. Once characterization of the air at a site has been accomplished, it may be appropriate to select an alternative to airline respirators and SCBAs. Respirator cartridges can be tested against specific chemical mixtures using worse case environmental factors. The results can be used to predict both the effectiveness and duration of protection afforded by respirator cartridges which can reduce costs and worker fatigue

We extend knowledge protection literature and propose theoretical mechanisms explaining how information visibility influences the importance...... of secrecy as a knowledge protection instrument. Building on mechanisms from information economics and signaling theory, we postulate that secrecy is more important for protecting knowledge for firms that have legal requirements to reveal information to shareholders. Furthermore, we argue that this effect...... and a firm's investment in fixed assets.

One of the conditions for the basic functions of the state is efficient administration headed by a person with the role of management. They not only hold the highest position, but also represent the authority of the state. For this reason, they need special protection. Each attack undermines the authority of the administration and trust in the state institutions. For the protection of persons performing managerial functions in the state corresponds to the Government Protection Bureau that providing them protection at the same time protect the state.

  3. Protected area certificates: gaining ground for better ecosystem protection?

    Science.gov (United States)

    Segerstedt, Anna; Grote, Ulrike

    2015-06-01

    Protected areas are vital to sustain a number of ecosystem services. Yet, many protected areas are underfinanced and lack management effectiveness. Protected area certificates have been suggested as a way to resolve these problems. This instrument would allow land managers to certify an area if it meets certain conservation criteria. The certificates could then be sold on an international market, for example to companies and any consumers that are interested in environmental protection. Some pilot initiatives have been launched, yet little is known about future demand and features of protected area certificates. To fill this knowledge gap, we conduct a choice experiment with close to 400 long-distance tourists from Germany as a potential group of buyers. Our results indicate that the respondents have the highest willingness to pay for certificates that conserve sensitive ecosystems and in addition to this lead to poverty reduction and safeguard water resources. For other attributes such as a greenhouse gas reduction, the preferences are less significant. Overall, the results are rather homogenous irrespective of where the protected areas are located. These insights are important for the future design and marketing of protected area certificates.

    This Practical Radiation Technical Manual is one of a series that has been designed to provide guidance on radiological protection for employers, radiation protection officers, managers and other technically competent persons who have responsibility for ensuring the safety of employees working with ionizing radiation. The Manual may be used with the appropriate IAEA Practical Radiation Safety Manuals to provide training, instruction and information for all employees engaged in work with ionizing radiation. Personal protective equipment (PPE) includes clothing or other special equipment that is issued to individual workers to provide protection against actual or potential exposure to ionizing radiations. It is used to protect each worker against the prevailing risk of external or internal exposure in circumstances in which it is not reasonably practicable to provide complete protection by means of engineering controls or administrative methods. Adequate personal protection depends on PPE being correctly selected, fitted and maintained. Appropriate training for the users and arrangements to monitor usage are also necessary to ensure that PPE provides the intended degree of protection effectively. This Manual explains the principal types of PPE, including protective clothing and respiratory protective equipment (RPE). Examples of working procedures are also described to indicate how PPE should be used within a safe system of work. The Manual will be of most benefit if it forms part of a more comprehensive training programme or is supplemented by the advice of a qualified expert in radiation protection. Some of the RPE described in this Manual should be used under the guidance of a qualified expert

    Directory of Open Access Journals (Sweden)

    R. Sitharthan

    2016-09-01

    Full Text Available This paper aims at modelling an electronically coupled distributed energy resource with an adaptive protection scheme. The electronically coupled distributed energy resource is a microgrid framework formed by coupling the renewable energy source electronically. Further, the proposed adaptive protection scheme provides a suitable protection to the microgrid for various fault conditions irrespective of the operating mode of the microgrid: namely, grid connected mode and islanded mode. The outstanding aspect of the developed adaptive protection scheme is that it monitors the microgrid and instantly updates relay fault current according to the variations that occur in the system. The proposed adaptive protection scheme also employs auto reclosures, through which the proposed adaptive protection scheme recovers faster from the fault and thereby increases the consistency of the microgrid. The effectiveness of the proposed adaptive protection is studied through the time domain simulations carried out in the PSCAD⧹EMTDC software environment.

    The protection of accelerator equipment is as old as accelerator technology and was for many years related to high-power equipment. Examples are the protection of powering equipment from overheating (magnets, power converters, high-current cables), of superconducting magnets from damage after a quench and of klystrons. The protection of equipment from beam accidents is more recent. It is related to the increasing beam power of high-power proton accelerators such as ISIS, SNS, ESS and the PSI cyclotron, to the emission of synchrotron light by electron–positron accelerators and FELs, and to the increase of energy stored in the beam (in particular for hadron colliders such as LHC). Designing a machine protection system requires an excellent understanding of accelerator physics and operation to anticipate possible failures that could lead to damage.

Machine protection includes beam and equipment monitoring, a system to safely stop beam operation (e.g. dumping the beam or stopping the beam at low energy) and an interlock system providing the glue between these systems. The most recent accelerator, the LHC, will operate with about 3 × 10 14 protons per beam, corresponding to an energy stored in each beam of 360 MJ. This energy can cause massive damage to accelerator equipment in case of uncontrolled beam loss, and a single accident damaging vital parts of the accelerator could interrupt operation for years. This article provides an overview of the requirements for protection of accelerator equipment and introduces the various protection systems. Examples are mainly from LHC, SNS and ESS

    This 3rd edition presents the official explanations of the legislative intent behind the Radiation Protection Ordinance of 1976 and the 2nd amending ordinance, and the commentaries which as usual refer to the legal aspects and the related medical, scientific, and technical aspects. As a consequence of the reactor accident at Chernobyl, the existing radiation protection law has been extended by the Act for Preventive Measures for Pretection of the Population Against the Hazards of Ionizing Radiation (Preventive Radiation Protection Act), establishing preventive legal provisions and measures, so that this new edition has likewise been extended by commentaries on the Protective Radiation Protection Act and an introduction to the new area of law. The material also includes the Act for Establishment of a Federal Office for Radiation Protection, of October 9, 1989, which amended the Atomic Energy Act and the Preventive Radiation Protection Act. The correction of the Radiation Protection Ordinance of October 16, 1989 (BGBl. I p. 1926) has been incorporated into the text of the amended version of the Radiation Protection Ordinance. Court decisions and literature referred to cover material published up to the first months of 1989. (orig.) [de

    Full Text Available Modern trends in relay protection (RP based on the substitution of electromechanical protection relays (EMPR by digital protective relays (DPR have resulted in the emergence of an absolutely new problem, which was not known before. This problem is the possibility of an intentional remote destructive impact (IRDI on relay protection in order to put it out of action or make it perform functions that have nothing to do with the current operational mode of protected electric equipment. Traditional and well-known methods ensuring information safety cannot fully prevent unauthorized actions of RP. The article describes a new way for the problem solution.

    Full text of publication follows: In order to improve the management of radiation protection at EDF nuclear power plants, the Human Factors Group of the Research and Development Division of EDF has performed some studies on the appropriation process of the radiation protection requirements. These studies have notably shown that an efficient application of the radiation protection requirements lies on a comprehension by all workers of the meaning of these requirements. Furthermore, they should not be applied under the constraint or because of the fear of a sanction, but the workers need to perceive and understand the benefits in terms of protection associated with the radiation protection requirements. The strengthening of the radiation protection culture is therefore a key element of the radiation protection policy developed by EDF. This culture lies on an awareness of the health risks potentially associated with low levels of ionising radiations, as well as on the knowledge of tools, techniques and good practices developed to control the level of exposures and improve the radiation protection. Various type of actions have been undertaken to reinforce among the relevant players (exposed and non-exposed workers, contractors, all levels of management,... ) an awareness of radiation protection in order to integrate it in their day to day work: elaboration of a 'radiation protection system of reference' explaining how the radiation protection regulatory requirements are applied at EDF, publication of a 'radiation protection handbook' available for all workers (including contractors), training sessions, creation of networks of specialists from the various nuclear power plants on specific radiation protection issues, organisation of feed-back experience forum, etc. Beyond these specific actions, i t is also important to ensure a support and an assistance on the field by dedicated specialists. In this perspective, the health physicists have to play a key role in order to

    Fire is an important disturbance agent in Myanmar impacting several ecosystems. In this study, we quantify the factors impacting vegetation fires in protected and non-protected areas of Myanmar. Satellite datasets in conjunction with biophysical and anthropogenic factors were used in a spatial framework to map the causative factors of fires. Specifically, we used the frequency ratio method to assess the contribution of each causative factor to overall fire susceptibility at a 1km scale. Results suggested the mean fire density in non-protected areas was two times higher than the protected areas. Fire-land cover partition analysis suggested dominant fire occurrences in the savannas (protected areas) and woody savannas (non-protected areas). The five major fire causative factors in protected areas in descending order include population density, land cover, tree cover percent, travel time from nearest city and temperature. In contrast, the causative factors in non-protected areas were population density, tree cover percent, travel time from nearest city, temperature and elevation. The fire susceptibility analysis showed distinct spatial patterns with central Myanmar as a hot spot of vegetation fires. Results from propensity score matching suggested that forests within protected areas have 11% less fires than non-protected areas. Overall, our results identify important causative factors of fire useful to address broad scale fire risk concerns at a landscape scale in Myanmar. PMID:25909632

    Full text: A large portion of the international community relies on expert judgment and military expertise to form the protection strategy of weapons-grade nuclear materials. This approach can be less than effectual for two primary reasons. First, much of the nuclear material that needs the most protection is not in a static form and located in easily secured storage locations. Some of the most effective measures for protection of in-process material are administrative and procedural in nature. There are basic protection differences between countries just like there are differences in baking bread. However, the necessary steps to produce bread are basically the same around the world. Certain ingredients are required to give it flavor, make it rise, and have a certain texture. So it is in the development of protection systems. A measure of intrusion detection, some access controls and searches, a pinch of computerized accounting, a layer of delay barriers, and a smidgen of armed response--and the basis for a 'cookbook' is born. Any and all protection systems can begin with simple elements that can be just as effective as the most sophisticated modern components. This paper will describe some of those simple, but effective, innovative protection measures. (author)

  13. Resilience from coastal protection.

    2015-10-28

    Coastal areas are important residential, commercial and industrial areas; but coastal hazards can pose significant threats to these areas. Shoreline/coastal protection elements, both built structures such as breakwaters, seawalls and revetments, as well as natural features such as beaches, reefs and wetlands, are regular features of a coastal community and are important for community safety and development. These protection structures provide a range of resilience to coastal communities. During and after disasters, they help to minimize damages and support recovery; during non-disaster times, the values from shoreline elements shift from the narrow focus on protection. Most coastal communities have limited land and resources and few can dedicate scarce resources solely for protection. Values from shore protection can and should expand to include environmental, economic and social/cultural values. This paper discusses the key aspects of shoreline protection that influence effective community resilience and protection from disasters. This paper also presents ways that the economic, environmental and social/cultural values of shore protection can be evaluated and quantified. It presents the Coastal Community Hazard Protection Resilience (CCHPR) Index for evaluating the resilience capacity to coastal communities from various protection schemes and demonstrates the use of this Index for an urban beach in San Francisco, CA, USA. © 2015 The Author(s).

  17. Protection from visible light by commonly used textiles is not predicted by ultraviolet protection.

    2006-01-01

    Interest is increasing in the prevention of acute and chronic actinic damage provided by clothing. This interest has focused mainly on protection against ultraviolet irradiation, but it has now also turned to protection against visible light. This change is mainly due to the action spectrum in the visible light range of some photodermatoses and the increasing interest in photodynamic therapy. The ultraviolet protection provided by commercially available textiles can be graded by determining an ultraviolet protection factor. Several methods have already been used to determine the ultraviolet protection factor. The fact that protection from visible light by textiles cannot be predicted by their ultraviolet protection makes the situation more complicated. This study attempts to determine whether or not the ultraviolet protection factor value of a particular textile is a good parameter for gauging its protection in the visible light range and concludes that a protection factor of textile materials against visible light needs to be developed. This development should go beyond the protection factor definition used in this article, which has some limitations, and should take into account the exact action spectrum for which the protection is needed.

    Radiation dose measurement, field of radiobiology, is considered to be critical factor for optimizing radiation protection to the health care practitioners, patients and the public. This lead to equipment that has dose - area product meters permanently installed. In many countries and even institution, the range of equipment is vast and with the opportunity for radiation protection and dose recording varies considerably. Practitioners must move with the changed demands of radiation protection but in many cases without assistance of modern advancements in technology Keeping the three basic safety measures Time, Dose and Shielding we can say 'Optimum dose is safe dose' instead of 'No dose is safe dose'. The purpose enclosed within the title 'Radiation Protection'. The use of radiation is expanding widely everyday around the world and crossing boundaries of medical imaging, diagnostic and. The way to get the ''As low as reasonably achievable' is only achievable by using methodology of radiation protection and to bring the concern of general public and practitioners over the hazards of un-necessary radiation dose. Three basic principles of radiation protection are time, distance and shielding. By minimizing the exposure time increasing the distance and including the shielding we can reduce the optimum range of dose. The ability of shielding material to attenuate radiation is generally given as half value layer. This is the thickness of the material which will reduce the amount of radiation by 50%. Lab coat and gloves must be worn when handling radioactive material or when working in a labeled radiation work area. Safety glasses or other appropriate splash shields should be used when handling radioactive material. 1. Reached to low dose level to occupational workers, public as per prescribed dose limit. 2.

    With the present knowledge, bentonite blocks have to be protected from the air relative humidity and from any moisture leakages in the environment that might cause swelling of the bentonite blocks during the 'open' installation phase before backfilling. The purpose of this work was to design the structural reference solution both for the bottom of the deposition hole and for the buffer moisture protection and dewatering system with their integrated equipment needed in the deposition hole. This report describes the Posiva's reference solution for the buffer moisture protection system and the bottom plate on basis of the demands and functional requirements set by long-term safety. The reference solution with structural details has been developed in research work made 2010-2011. The structural solution of the moisture protection system has not yet been tested in practice. On the bottom of the deposition hole a copper plate which protects the lowest bentonite block from the gathered water is installed straight to machined and even rock surface. The moisture protection sheet made of EPDM rubber is attached to the copper plate with an inflatable seal. The upper part of the moisture protection sheet is fixed to the collar structures of the lid which protects the deposition hole in the disposal tunnel. The main function of the moisture protection sheet is to protect bentonite blocks from the leaking water and from the influence of the air humidity at their installation stage. The leaking water is controlled by the dewatering and alarm system which has been integrated into the moisture protection liner. (orig.)

    1997-01-01

    Lead powder and oxygenated lead are widely used as materials in conventional protective aprons. However, the use of lead alone limits weight reduction in an apron. Because the amount of lead can not be decreased without reducing X-ray absorption rate. In this study, we report the efficiency of a new X-ray protective apron with a composite protective sheet. The X-ray absorption rate of the composite sheet was 4.5 percent less than that of the lead sheet. However, the effective protective efficiency of the composite sheet was the same as that of the lead sheet. The uniformity of the new X-ray protective apron was good, and the differences among products were small. The new X-ray protective apron was about 30 percent lighter than a lead apron with a 0.25 mm lead equivalent. The new lighter aprons are more comfortable for the radiology staff. Therefore, the use of a composite protective apron provides the advantages of weight reduction and increased comfort without reducing X-ray absorption rate. (author)

According to the Radiation Protection Ordinance the person with responsibility in radiation protection has to guarantee that the training is performed twice a year. Our training material was created especially for the persons defined in the Radiation Protection Ordinance and the X-ray Ordinance. It enables persons who teach (generally the radiation protection officer) to perform the training without tedious study and preparation of the documents. Our material is not just another textbook for radiation protection but rather a folder with colour transparencies and explanatory texts which make a difference in volume and price in comparison to other existing materials.

    1988-01-01

    EH is developing a DOE-wide Groundwater Quality Protection Strategy to express DOE's commitment to the protection of groundwater quality at or near its facilities. This strategy responds to a September 1986 recommendation of the General Accounting Office. It builds on EPA's August 1984 Ground-Water Protection Strategy, which establishes a classification system designed to protect groundwater according to its value and vulnerability. The purposes of DOE's strategy are to highlight groundwater protection as part of current DOE programs and future Departmental planning, to guide DOE managers in developing site-specific groundwater protection practices where DOE has discretion, and to guide DOE's approach to negotiations with EPA/states where regulatory processes apply to groundwater protection at Departmental facilities. The strategy calls for the prevention of groundwater contamination and the cleanup of groundwater commensurate with its usefulness. It would require long-term groundwater protection with reliance on physical rather than institutional control methods. The strategy provides guidance on providing long-term protection of groundwater resources; standards for new remedial actions;guidance on establishing points of compliance; requirements for establishing classification review area; and general guidance on obtaining variances, where applicable, from regulatory requirements. It also outlines management tools to implement this strategy

    The basis of EU radiation protection legislation is the EURATOM Trealy. It is discussed whether the Treaty offers a legal basis for the protection of the natural environment. The incorporation of provisions pertaining to the nuclear fuel cycle or to radioactive substances in general environmental legislation is explained, as well as the possible implications of international conventions subscribed by the European Union. The European Commission is in the process of developing an overall approach to risk analysis for the protection of health, consumer interests, and the environment. It is examined to what extent the consideration of the impact of radiation on the natural environment fits in the overall framework and whether the principles underlying classical radiation protection are applicable to biota. Specific attention is given to situations where high levels of environmental radioactivity would require intervention. (Author)

    This paper relates to a plant protection system which detects non-permissible conditions and determines initiation of protective actions for nuclear power plants (NPPs). Conventional plant protection systems were designed based on analog technologies. It is well known that existing protection systems for NPPs contain many components which are becoming obsolete at an increasing rate. Nowadays maintenance and repair for analog-based plant protection systems may be difficult as analog parts become obsolete or difficult to obtain.

    This paper relates to a plant protection system which detects non-permissible conditions and determines initiation of protective actions for nuclear power plants (NPPs). Conventional plant protection systems were designed based on analog technologies. It is well known that existing protection systems for NPPs contain many components which are becoming obsolete at an increasing rate. Nowadays maintenance and repair for analog-based plant protection systems may be difficult as analog parts become obsolete or difficult to obtain. Accordingly, as an alternative to the analog technology, the digitalisation of the plant protection system was required. Recently digital plant protection systems which include programmable logic controllers (PLCs) and/or computers have been introduced. However PLC or computer-based plant protection systems use an operating system and application software, and so they may result in a common mode failure when a problem occurs in the operating system or application software.

    Beavers are a protected species, so the levees must be properly protected so as not to harm the beavers and protect the levees from the destruction caused by these animals. This protection requires the use of bentonite mats as shaft seals, and wire mesh. Recently, such new protection structures began to be used successfully.

    Occupational exposures to radiation from tritium received at present nuclear facilities and potential exposures at future fusion reactor facilities demonstrate the need for improved protective clothing. Important areas relating to increased protection factors of tritium protective ventilation suits are discussed. These areas include permeation processes of tritium through materials, various tests of film permeability, selection and availability of suit materials, suit designs, and administrative procedures. The phenomenological nature of film permeability calls for more standardized and universal test methods, which would increase the amount of directly useful information on impermeable materials. Improvements in suit designs could be expedited and better communicated to the health physics community by centralizing devlopmental equipment, manpower, and expertise in the field of tritium protection to one or two authoritative institutions

    1976-06-01

    The EPA, under its Federal Guidance authorities, is responsible for advising the President on all matters pertaining to radiation and, through this mechanism, to provide guidance to other Federal agencies on radiation protection matters. Highlights are presented of significant radiation protection activities of all Federal agencies which were completed in 1975, or in which noteworthy progress was made during that period, and those events affecting members of the public. State or local activities are also presented where the effects of those events may be more far-reaching. At the Federal level significant strides have been made in reducing unnecessary radiation exposure through the efforts of the responsible agencies. These efforts have resulted in the promulgation of certain standards, criteria and guides. Improved control technologies in many areas make it feasible to reduce emissions at a reasonable cost to levels below current standards and guides. This report provides information on the significant activities leading to the establishment of the necessary controls for protection of public health and the environment. Radiation protection activities have been undertaken in other areas such as medical, occupational and consumer product radiation. In the context of radiation protection, ancillary activities are included in this report in order to present a comprehensive overview of the events that took place in 1975 that could have an effect on public health, either directly or indirectly. Reports of routine or continuing radiation protection operations may be found in publications of the sponsoring Federal agencies, as can more detailed information about activities reported in this document. A list of some of these reports is included

    Protected areas cover over 12% of the terrestrial surface of Earth, and yet many fail to protect species and ecological processes as originally envisioned. Results of recent studies suggest that a critical reason for this failure is an increasing contrast between the protected lands and the surrounding matrix of often highly altered land cover. We measured the isolation of 114 protected areas distributed worldwide by comparing vegetation-cover heterogeneity inside protected areas with heterogeneity outside the protected areas. We quantified heterogeneity as the contagion of greenness on the basis of NDVI (normalized difference vegetation index) values, for which a higher value of contagion indicates less heterogeneous land cover. We then measured isolation as the difference between mean contagion inside the protected area and mean contagion in 3 buffer areas of increasing distance from the protected-area border. The isolation of protected areas was significantly positive in 110 of the 114 areas, indicating that vegetation cover was consistently more heterogeneous 10-20 km outside protected areas than inside their borders. Unlike previous researchers, we found that protected areas in which low levels of human activity are allowed were more isolated than areas in which high levels are allowed. Our method is a novel way to assess the isolation of protected areas in different environmental contexts and regions. ©2011 Society for Conservation Biology.

  10. The Radiation Protection Act

    1989-01-01

    The new Radiation Protection Act (1988:220) entered into force in Sweden on July 1st, 1988. This book presents the Act as well as certain regulations connected to it. As previously, the main responsibility for public radiation protection will rest with one central radiation protection authority. According to the 1988 Act, the general obligations with regard to radiation protection will place a greater responsibility than in the past on persons carrying out activities involving radiation. Under the act, it is possible to adjust the licensing and supervisory procedures to the level of danger of the radiation source and the need for adequate competence, etc. The Act recognises standardised approval procedures combined with technical regulations for areas where the risks are well known. The Act contains several rules providing for more effective supervision. The supervising authority may in particular decide on the necessary regulations and prohibitions for each individual case. The possibilities of using penal provisions have been extended and a rule on the mandatory execution of orders has been introduced. The Ordinance on Radiation Protection (1988:293) designates the National Institute of Radiation Protection (SSI) as the central authority referred to in the Radiation Protection Act. The book also gives a historic review of radiation protection laws in Sweden, lists regulations issued by SSI and presents explanations of radiation effects and international norms in the area.

    Power systems of the 21st century will be more modern, and complex, utilizing the latest available technologies. At the same time, generating plants will have to operate with minimal spinning margins and energy transportation has to take place at critical levels due to environmental and economical constraints. These factors dictate that the power systems be protected with optimum sensitivity, selectivity and time of operation to assure maximum reliability, and security at minimal cost. With an increasing role played by digital computers in every aspect of protection, it is important to take a critical and fresh look at the art and science of relaying and protection. The main objective of this paper is to review the past, present and future of power system protection from a software point of view

    In the development of physical protection systems, objectives for improving overall performance include the following: (1) Increase the time required for the malefactor to achieve his goal; (2) decrease the time required for detection of malevolent activities; (3) reduce the time for adequate response force arrival; (4) increase the capability to neutralize the malefactor; (5) reduce the total protection system costs, while increasing the level of protection; (6) improve acceptance levels (social, environmental, legal, and institutional); and (7) increase nuclear fuel cycle safety. Fortunately, there is sufficient lead time and technical base to explore and develop new protection system concepts so that a completely integrated and tested protection system capable of providing unprecedented levels of security can be available when needed. Although it will be impossible to completely eliminate all risks, it should be both possible and economically feasible to install protection systems which will deter or prevent a malefactor from using the nuclear fuel cycle to disrupt society

    In order to identify radiation protection current situation in national X-ray diagnostic practice , the State (cuban) Supervision System for Radiation and Nuclear Safety carried out in 1992 a survey which was planned for projection of future regulatory activities in this field. Survey covers the most important aspects related to radiation protection of occupationally exposed workers, patients and general population. Surveyed sample included a total of 52 X-ray units, sited in 7 dental clinics, 2 polyclinics and 13 hospitals, from 7 provinces of the country. Results showed that the organization of radiation protection in terms of personnel specially designated to carry out surveillance and control activities and level of documentation is deficient. Survey evidenced the general lack of safety and quality culture among technologists and radiologists which is mainly reflected in non regular application of basic patient protection measures (shielding, collimation, use of proper filtration among others) and non regular execution of basic quality inspection of employed radiographic systems.

    When designing any power converter it is essential to assess and incorporate adequate protection. The main objective is to offer a solution which is safe, reliable and repairable and that achieves its specification within budget. The level of protection found within each converter varies widely and will depend on the topology employed, its application and rating. This document is a guide to the types of protection engineers should consider mainly when designing power converters, as protection added during construction or after installation will always be expensive.

    1983-01-01

    Two basic approaches have evolved over the past several years for physical protection against sabotage by insiders. One, area-type physical protection, involves the use of access controls at area boundaries. Current practices at nuclear power plants generally fall into this category. The second, component-level physical protection, involves hardware at individual components as well as access controls at the boundary. The area-type physical protection concepts include team, area, and operational zoning. Team zoning requires the formation of multiperson teams that must be used to gain access to vital areas. Area zoning divides the plant into two or more zones, each of which is operated and maintained by separate, dedicated teams. Operational zoning is a closed-loop access control system that permits an initial vital area access, but blocks access to certain other vital areas until the operability of equipment in the first area is verified by test or inspection. Component-level physical protection is also a closed-loop system in which both area and component access are monitored. Each of the above measures can provide effective protection against an insider in certain instances, but each has weaknesses that must be recognized. An approach for protection against the insider is to take the most promising features of each of the above physical protection measures and supplement these capabilities with damage control and design changes as appropriate for a particular plant

    Concrete is the most convenient material when large-scale radiation protection is needed. Thus, special concretes for nuclear purposes are used in various facilities like reactors, reprocessing centers, storage sites, accelerators, hospitals with nuclear medicine equipment, food ionization centers etc.. The recent advances made in civil engineering for the improvement of concrete durability and compactness are for a large part transposable to protection concretes. This article presents the basic knowledge about protection concretes with the associated typological and technological aspects. A large part is devoted to the intrinsic properties of concretes and to their behaviour in irradiation and temperature conditions: 1 - definition and field of application of special protective concretes; 2 - evolution of concepts and technologies (durability of structures, techniques of formulation, new additives, market evolution); 3 - design of protective structures (preliminary study, radiation characteristics, thermal constraints, damping and dimensioning, mechanical criteria); 4 - formulation of special concretes (general principles, granulates, hydraulic binders, pulverulent additives, water/cement ratio, reference composition of some special concretes); 5 - properties of special concretes (damping and thermo-mechanical properties); 6 - induced-irradiation and temperature phenomena (activation, radiolysis, mineralogical transformations, drying, shrinking, creep, corrosion of reinforcement).

    Full Text Available The All-Russian Congress “Fire Stop Moscow” was de-voted to the analysis of the four segments of the industry of fire protection systems and technologies: the design of fire protec-tion systems, the latest developments and technologies of active and passive fire protection of buildings, the state and the devel-opment of the legal framework, the practice of fire protection of buildings and structures. The forum brought together the repre-sentatives of the industry of fire protection systems, scientists, leading experts, specialists in fire protection and representatives of construction companies from different regions of Russia. In parallel with the Congress Industrial Exhibition of fire protection systems, materials and technology was held, where manufacturers presented their products. The urgency of the “Fire Stop Moscow” Congress in 2015 organized by the Congress Bureau ODF Events lies primarily in the fact that it considered the full range of issues related to the fire protection of building and construction projects; studied the state of the regulatory framework for fire safety and efficiency of public services, research centers, private companies and busi-nesses in the area of fire safety. The main practical significance of the event which was widely covered in the media space, was the opportunity to share the views and information between management, science, and practice of business on implementing fire protection systems in the conditions of modern economic relations and market realities. : congress, fire protection, systems, technologies, fire protection systems, exhibition

  11. VIP protection from CBRN hazards

    International Nuclear Information System (INIS)

    Kaszeta, D.

    2009-01-01

    Protection of heads of state/government from CBRN threats requires flexibility and advanced planning. The best approach to CBRN countermeasures in a close protection context combine traditional close protection techniques, sound security practices, and a good understanding of the technical nature of the threat. Poor general security practices make for poor CBRN protection. This paper addresses a methodology for assessing the viability of threats to protected persons/VIPs and provides an overview of close protection in the CBRN environment. It is important to define the scope of CBRN response in the close protection context. Some threat agents are more applicable to a military environment than to the type of attack consistent with assassination. By focussing the scope of CBRN close protection more specifically on the more technically viable threats, appropriate concepts of operation can be developed. Concepts of operation, developed with an understanding of the threat, determine the requirement for advanced preparation and the training and equipping of protective details. Most of the responses required in CBRN incidents are well served by tactically sound close protection procedures. The fundamental principles are: rapid identification of hazard, speed, use of protective technology, and medical interventions, including rapid decontamination and basic and advanced life support measures.

  12. Wake Shield Target Protection

    International Nuclear Information System (INIS)

    Valmianski, Emanuil I.; Petzoldt, Ronald W.; Alexander, Neil B.

    2003-01-01

    The heat flux from both gas convection and chamber radiation on a direct drive target must be limited to avoid target damage from excessive D-T temperature increase. One of the possibilities of protecting the target is a wake shield flying in front of the target. A shield will also reduce drag force on the target, thereby facilitating target tracking and position prediction. A Direct Simulation Monte Carlo (DSMC) code was used to calculate convection heat loads as boundary conditions input into ANSYS thermal calculations. These were used for studying the quality of target protection depending on various shapes of shields, target-shield distance, and protective properties of the shield moving relative to the target. The results show that the shield can reduce the convective heat flux by a factor of 2 to 5 depending on pressure, temperature, and velocity. The protective effect of a shield moving relative to the target is greater than the protective properties of a fixed shield. However, the protective effect of a shield moving under the drag force is not sufficient for bringing the heat load on the target down to the necessary limit. Some other ways of diminishing heat flux using a protective shield are discussed

    1996-01-01

    The optimization concept in radiation protection is, in its essence, practical. In each aspect that we deal with the man, it is necessary to take frequent decisions such as: what is the protection level to be pursued, since the protection levels under consideration provide doses lower than the appropriate annual limits. The optimization gives a basic framework of the minding that is appropriate to conduct to a balance kind of the resources available for the protection and protection level obtained against a multitude of factors and constrains in a manner to obtain the best result. In this work, was performed the optimization, from the radiation protection point of view, of a facility project who enclose two shielded hot cells where will be handled UO 2 small plate with 50% of U-235 burn-up, irradiated in the research swimming pool reactor, IEA-R1. To obtain this goal were specified the relevant factors and criteria, were applied the main techniques used in a decision-making in radiological protection, presently adopted and was performed a sensibility study of the factors and criteria used in this work. In order to obtain a greater agility in applying the techniques for decision-making was developed a micro computer program. (author)

    To compare counseling concerning sun protection and outdoor exercise with the parent's report of the behavior of a child aged 9-16 years old. Structured interviews of medical personnel in 3 Chicago area practices elicited information about counseling methods and recommendations. In each practice, a convenience sample of parents completed a self-reported survey of their and their child's behavior. Sun protection counseling occurred more frequently than exercise counseling in all practices (P = .014). Sun protection counseling was associated with parental prompting (P = .004), performing a summer camp physical (P = .002), and the child having a sunburn (P = .003). After controlling for the child's age, sex, and skin tone, sun protection counseling was not associated with the child's use of sun protection. In multivariate analysis of the child's sun protection behavior, parental sunburns, indoor tanning in the last 12 months, perception of skin cancer risk, and sun protection self-efficacy were significant (P = .02). Children who pursued outdoor sports were twice as likely to use inadequate sun protection and sustain sunburns (CI 1.3-1.7). The child's sun protection behavior was influenced by parental sun protection, parental perception of skin cancer risk, and parental sun protection self-efficacy; therefore, sun protection for children needs to be aimed at parents as well as children. Communication with parents in a way that incorporates the principles of motivational interviewing may be more effective in promoting behavioral change than admonitions to use sunscreen.

  15. Optimisation of radiation protection

    International Nuclear Information System (INIS)

    1988-01-01

    Optimisation of radiation protection is one of the key elements in the current radiation protection philosophy. The present system of dose limitation was issued in 1977 by the International Commission on Radiological Protection (ICRP) and includes, in addition to the requirements of justification of practices and limitation of individual doses, the requirement that all exposures be kept as low as is reasonably achievable, taking social and economic factors into account. This last principle is usually referred to as optimisation of radiation protection, or the ALARA principle. The NEA Committee on Radiation Protection and Public Health (CRPPH) organised an ad hoc meeting, in liaison with the NEA committees on the safety of nuclear installations and radioactive waste management. Separate abstracts were prepared for individual papers presented at the meeting

    Carotid angioplasty and stenting is a valid alternative option to conventional carotid endarterectomy in the treatment of carotid artery stenosis. During the stenting process, however, distal embolization can occur with neurological consequences. To avoid this, cerebral protection devices have been introduced. Three principal types of protection system have been developed: distal balloon occlusion, distal filters and proximal protection with or without reversal of flow. As protection devices became the focus of interest by manufactures and physicians, several trials are going on worldwide to analyze the characteristics of each of them and to evaluate their efficacy to reduce the rate of distal embolization.

    1996-01-01

    Mires in Germany are mainly used for agriculture. Peat mining is important regionally, but forest utilisation less so. Twenty years ago in the former West Germany, the first steps from peatland utilisation to peatland protection were taken. Bog protection programmes were developed first. Nowadays research directed to fen protection has begun, prompted by the decreasing importance of agriculture in Central Europe and an increasing environmental awareness. The situation regarding mire protection in Germany is presented for each Federal State individually. A rough estimate suggests 45 000 ha of protected bogs and 25 000 ha of protected fens. These areas include natural and semi-natural mires as well as rewetted mires. (30 refs.)

    National parks and other protected areas are at the forefront of global efforts to protect biodiversity and ecosystem services. However, not all protection is equal. Some areas are assigned strict legal protection that permits few extractive human uses. Other protected area designations permit a wider range of uses. Whether strictly protected areas are more effective in achieving environmental objectives is an empirical question: although strictly protected areas legally permit less anthropogenic disturbance, the social conflicts associated with assigning strict protection may lead politicians to assign strict protection to less-threatened areas and may lead citizens or enforcement agents to ignore the strict legal restrictions. We contrast the impacts of strictly and less strictly protected areas in four countries using IUCN designations to measure de jure strictness, data on deforestation to measure outcomes, and a quasi-experimental design to estimate impacts. On average, stricter protection reduced deforestation rates more than less strict protection, but the additional impact was not always large and sometimes arose because of where stricter protection was assigned rather than regulatory strictness per se. We also show that, in protected area studies contrasting y management regimes, there are y 2 policy-relevant impacts, rather than only y, as earlier studies have implied. (letter)

    2004-01-01

    Depending on the facility, a radiation protective apron (protector) is used to protect the gonad from radiation exposure in chest radiography. To determine the necessity of using a protector during chest radiography, we measured the effect of the protector on the gonad in this study. First, using a human body phantom, we measured the absorbed dose of the female gonad with and without the protector, using a thermoluminescence dosimeter (TLD), and confirmed its protective effect. Using the protector, the absorbed dose was reduced to 28±2% and 39±4% for field sizes of 14 x 17 inch and 14 x 14 inch, respectively. Next, we used Monte Carlo simulation and confirmed, not only the validity of the actual measurement values, but also the fact that the influence of radiation on the absorbed dose of the gonad was mostly from scattered radiation from inside the body for the 14 x 17 inch field size, and also from the X-ray tube for the 14 x 14 inch field size. Although a certain protective effect is achieved by using the protector, the radiation dose to the gonad is only a few μGy even without a protector. Thus, the risk of a genetic effect would be as small as 10 -8 . Given that acceptable risk is below 10 -6 , we conclude the use of a radiation protective apron is not necessary for diagnostic chest radiography. (author)

  8. A Novel Adjustable Concept for Permeable Gas/Vapor Protective Clothing: Balancing Protection and Thermal Strain.

    Science.gov (United States)

    Bogerd, Cornelis Peter; Langenberg, Johannes Pieter; DenHartog, Emiel A

    2018-02-13

    Armed forces typically have personal protective clothing (PPC) in place to offer protection against chemical, biological, radiological and nuclear (CBRN) agents. The regular soldier is equipped with permeable CBRN-PPC. However, depending on the operational task, these PPCs pose too much thermal strain to the wearer, which results in a higher risk of uncompensable heat stress. This study investigates the possibilities of adjustable CBRN-PPC, consisting of different layers that can be worn separately or in combination with each other. This novel concept aims to achieve optimization between protection and thermal strain during operations. Two CBRN-PPC (protective) layers were obtained from two separate manufacturers: (i) a next-to-skin (NTS) and (ii) a low-burden battle dress uniform (protective BDU). In addition to these layers, a standard (non-CBRN protective) BDU (sBDU) was also made available. The effect of combining clothing layers on the levels of protection were investigated with a Man-In-Simulant Test. Finally, a mechanistic numerical model was employed to give insight into the thermal burden of the evaluated CBRN-PPC concepts. Combining layers results in substantially higher protection that is more than the sum of the individual layers. Reducing the airflow on the protective layer closest to the skin seems to play an important role in this, since combining the NTS with the sBDU also resulted in substantially higher protection. As expected, the thermal strain posed by the different clothing layer combinations decreases as the level of protection decreases. This study has shown that the concept of adjustable protection and thermal strain through multiple layers of CBRN-PPC works. Adjustable CBRN-PPC allows for optimization of the CBRN-PPC in relation to the threat level, thermal environment, and tasks at hand in an operational setting. © The Author(s) 2017.

    Radiation protection in Bolivia has gone through a number of stages. Initially, in the 1970s, the focus was mainly on the analysis of environmental sources resulting from the nuclear tests carried out by France in the Pacific Ocean. Subsequently, the focus switched somewhat to radiation protection in connection with the mining of uranium and in the area of public health. During the third stage, radiation protection in other areas became important as the use of radiation sources was introduced. Finally, during the present -- fourth -- stage, radiation protection regulations are being introduced and mechanisms for the control of radiation sources are being established. (author)

  13. The Bald And Golden Eagle Protection Act, Species-Based Legal Protection And The Danger Of Misidentification

    Directory of Open Access Journals (Sweden)

    Johann C Knobel

    2015-12-01

    Full Text Available The Bald and Golden Eagle Protection Act of 1940 bestows legal protection on two North American eagle species in the United States of America. The Act was originally aimed at the legal protection of only one species: the Bald Eagle Haliaeetus leucocephalus, the national symbol of the USA. Later the Act was amended to extend protection also to the Golden Eagle Aquila chrysaetos. The Bald Eagle was an Endangered Species, but the Golden Eagle was not formally listed as Endangered nationwide in the USA. One of the reasons for extending legal protection to the Golden Eagle under the Act was to strengthen the legal protection of the Bald Eagle, because immature Bald Eagles were being misidentified as Golden Eagles and shot. Additional factors relating to Golden Eagle mortality also made legal protection of the Golden Eagle desirable. The danger that a rare and legally protected species can be misidentified and mistaken for a more common and unprotected species can therefore serve as a reason for bestowing legal protection on the more common species as well. Other factors may also indicate that legal protection of the more common species is desirable, making the case more compelling. If this line of reasoning is applied in respect of South African birds of prey, a strong case can be made in favour of extending legal protection under the national biodiversity legislation to more species than the small number of species currently enjoying such protection. Species that are listed as Vulnerable under South African national biodiversity legislation may be misidentified as species that are not subject to such protection. Additional factors are also present that make such an extension of legal protection desirable.

    The German Society for Radiation Protection (in German Gesellschaft fur Strahlenschutz) is a separate society for radiation protection in Germany in addition to the leading society named Association of German and Swiss Radiation Protection Specialists (in German Fachverband fur Strahlenschutz). The Society is an international professional society. There are several hundreds members of the German Society for Radiation Protection. The German Society for Radiation Protection is not a member of IRPA (the International Radiation Protection Society). The IRPA member is the Association of German and Swiss Radiation Protection Specialists. According to information given on the web site of the Society for Radiation Protection (www.gfstrahlenschutz.de) the Society was founded in 1990 because in the opinion of the founding members the older professional societies and associations have not adequately considered and implemented the present knowledge of radiation risks and radiation protection. In accordance with its statutes the society pursues besides other aims the best possible protection of humans and the environment from the detrimental action of ionising and non-ionising radiation. The dealing with ionising and non-ionising radiation can according to the Society only be justified on the basis of biological and medical state of the art knowledge

    Full Text Available Should the entire Antarctic continent and the surrounding islands be recognised as a ‘protected area’ or as a continent where certain areas, just like anywhere else, may be designated as protected areas? To find an answer to this question, this paper first discusses the most important agreements and declarations on environmental protection in Antarctica. Next, these instruments are compared with the components of IUCN’s ‘protected area’ definition (2008. In the light of this overall protection of Antarctica, the instrument of designating areas as Antarctic Specially Protected Areas (ASPAs is discussed on the basis of a quick scan of 42 management plans for existing ASPAs. It is concluded that Antarctica could indeed be considered as a protected area and that the ASPA instrument is so shaped to provide specific areas with ‘extra protection’ by regulating human activities in those areas with a high level of detail. However, the continuous increase in human activities in Antarctica raises concerns with respect to the scope and completeness of the existing legal instruments. These concerns regarding the overall protection of Antarctica could become an argument for applying the ASPA instrument in respect of larger areas to ensure the comprehensive protection of at least certain parts of Antarctica. This would make the ASPA system more comparable with protected area systems in other parts of the world; however, strengthening the overall protection of Antarctica – parallel to the further development of the ‘specially’ protected area system - would be more consistent with Antarctica’s protected status as has developed since the Antarctic Treaty was signed 50 years ago.

  3. The usage of phase change materials in fire fighter protective clothing: its effect on thermal protection

    Science.gov (United States)

    Zhao, Mengmeng

    2017-12-01

    The thermal protective performance of the fire fighter protective clothing is of vital importance for fire fighters. In the study fabrics treated by phase change materials (PCMs) were applied in the multi-layered fabrics of the fire fighter protective clothing ensemble. The PCM fabrics were placed at the different layers of the clothing and their thermal protective performance were measured by a TPP tester. Results show that with the application of the PCM fabrics the thermal protection of the multi-layered fabrics was greatly increased. The time to reach a second degree burn was largely reduced. The location of the PCM fabrics at the different layers did not affect much on the thermal protective performance. The higher amount of the PCM adds on, the higher thermal protection was brought. The fabrics with PCMs of a higher melting temperature could contribute to higher thermal protection.

    2014-01-01

    This book addresses key aspects of analog integrated circuits and systems design related to system level electrostatic discharge (ESD) protection.  It is an invaluable reference for anyone developing systems-on-chip (SoC) and systems-on-package (SoP), integrated with system-level ESD protection. The book focuses on both the design of semiconductor integrated circuit (IC) components with embedded, on-chip system level protection and IC-system co-design. The readers will be enabled to bring the system level ESD protection solutions to the level of integrated circuits, thereby reducing or completely eliminating the need for additional, discrete components on the printed circuit board (PCB) and meeting system-level ESD requirements. The authors take a systematic approach, based on IC-system ESD protection co-design. A detailed description of the available IC-level ESD testing methods is provided, together with a discussion of the correlation between IC-level and system-level ESD testing methods. The IC-level ESD...

  6. Introduction to Machine Protection

    CERN Document Server

    Schmidt, R

    2016-01-01

    Protection of accelerator equipment is as old as accelerator technology and was for many years related to high-power equipment. Examples are the protection of powering equipment from overheating (magnets, power converters, high-current cables), of superconducting magnets from damage after a quench and of klystrons. The protection of equipment from beam accidents is more recent, although there was one paper that discussed beam-induced damage for the SLAC linac (Stanford Linear Accelerator Center) as early as in 1967. It is related to the increasing beam power of high-power proton accelerators, to the emission of synchrotron light by electron-positron accelerators and to the increase of energy stored in the beam. Designing a machine protection system requires an excellent understanding of accelerator physics and operation to anticipate possible failures that could lead to damage. Machine protection includes beam and equipment monitoring, a system to safely stop beam operation (e.g. dumping the beam or stopping ...

  7. Is radiation protection for the unborn child guaranteed by radiation protection for female workers?

    International Nuclear Information System (INIS)

    Nosske, C.; Karcher, K.

    2003-01-01

    ICRP Publication 88 recommends doses to embryo and fetus from intakes of radionuclides by the mother for various intake scenarios. Mainly by answering the question 'Is radiation protection for the unborn child guaranteed by radiation protection for female workers?' it has been assessed if the intake scenarios given in ICRP Publication 88 are adequate for radiation protection purposes. This is generally the case, but the consideration of an additional chronic intake scenario for early pregnancy would be helpful. It is demonstrated that following chronic intake by inhalation, for most radionuclides radiation protection for (female) workers is also adequate for protection of the unborn child, considered as a member of the public. However, there are a number of radionuclides for which possible intakes in routine operations should be more restricted (up to 1% of the annual limits on intake for workers in the case of nickel isotopes) to ensure radiation protection for the unborn child.

    Expedient methods were developed that could be used by an average person, using only materials readily available, to protect himself and his family from injury by toxic (e.g., radioactive) aerosols. The most effective means of protection was the use of a household vacuum cleaner to maintain a small positive pressure on a closed house during passage of the aerosol cloud. Protection factors of 800 and above were achieved.

    1995-01-01

    The Department of Energy (DOE) is in the process of defining the magnitude and diversity of Decontamination and Decommissioning (D ampersand D) obligations at its numerous sites. The DOE believes that existing technologies are inadequate to solve many challenging problems such as how to decontaminate structures and equipment cost effectively, what to do with materials and wastes generated, and how to adequately protect workers and the environment. Preliminary estimates show a tremendous need for effective use of resources over a relatively long period (over 30 years). Several technologies are being investigated which can potentially reduce D ampersand D costs while providing appropriate protection to DOE workers. The DOE recognizes that traditional methods used by the EPA in hazardous waste site clean up activities are insufficient to provide the needed protection and worker productivity demanded by DOE D ampersand D programs. As a consequence, new clothing and equipment which can adequately protect workers while providing increases in worker productivity are being sought for implementation at DOE sites. This project will result in the development of an Advanced Worker Protection System (AWPS). The AWPS will be built around a life support backpack that uses liquid air to provide cooling as well as breathing gas to the worker. The backpack will be combined with advanced protective garments, advanced liquid cooling garment, respirator, communications, and support equipment to provide improved worker protection, simplified system maintenance, and dramatically improve worker productivity through longer duration work cycles. Phase I of the project has resulted in a full scale prototype Advanced Worker Protection Ensemble (AWPE, everything the worker will wear), with sub-scale support equipment, suitable for integrated testing and preliminary evaluation. Phase II will culminate in a full scale, certified, pre-production AWPS and a site demonstration

    2003-01-01

    The effects of ionising radiation on man has been studied intensely for decades, and the system of radiation protection for man has been continually refined in the light of those studies. That system assumes that if man is protected, non-human biota at the species level will also be adequately protected. However, an increasing recognition of the need to protect the environment, and international agreements signed in 1992, have resulted in that paradigm being questioned, with the onus shifting slowly towards demonstrating that the environment is protected. Further, radiation protection agencies and environmental protection agencies around the world have now started considering the issue of developing a system of radiation protection for the environment. The International Commission on Radiological Protection (ICRP) and the International Atomic Energy Agency (IAEA) are also active in this area. The purpose of this paper is to briefly outline some of the issues confronting environmental and radiation protection specialists, and to mention some of the initiatives being taken by the international community to resolve those issues

    Radiation Protection Training is an important component of Radiation Protection and serves for human radiation safety. According to the Lithuanian Law on Radiation Protection the legal persons and enterprises without the status of legal persons to conduct practices with sources or which workers work under exposure must organize at their own expenses a compulsory training and assessment of knowledge of the workers engaging in activities with the sources and radiation protection officers. Such training has been started in 1999. In Lithuania there are few institutions executing Radiation Protection training. Under requirements of legal act On Frequency and Procedure of Compulsory Training and Assessment Knowledge of the Workers Engage in Activities with the Sources of Ionising Radiation and Radiation Protection Officers these institutions have to prepare and coordinate training programs with the Radiation Protection Center. There are adopted different educating programs for Radiation Protection Training to the Workers and Radiation Protection Officers depending on character of work and danger of sources. The duration of Training is from 30 to 270 hours. The Training shall be renewed every five years passing 30 hors course. To ensure the adequate quality of training a great deal of attention is paid to qualifying the lectures. For this purpose, it was established an Evaluation commission to estimate the adequacy of lecturer's knowledge to requirements of Training programs. After passing exams the lectures get the qualification confirming certificates. The main task of our days is to establish and arrange the National Training Centre on Radiation Protection Training that would satisfy requirements and recommendations of legal documents of IAEA and EU for such kind of institutions of institutions.

    US Department of Energy (DOE) Order 5400.1 requires the establishment of a groundwater protection management program to ensure compliance with DOE requirements and applicable Federal, state, and local laws and regulations. The Uranium Mill Tailings Remedial Action (UMTRA) Project Office has prepared a ''Groundwater Protection Management Program Plan'' (groundwater protection plan) of sufficient scope and detail to reflect the program's significance and address the seven activities required in DOE Order 5400.1, Chapter 3, for special program planning. The groundwater protection plan highlights the methods designed to preserve, protect, and monitor groundwater resources at UMTRA Project processing and disposal sites. The plan includes an overview of the remedial action status at the 24 designated processing sites and identifies project technical guidance documents and site-specific documents for the UMTRA groundwater protection management program. In addition, the groundwater protection plan addresses the general information required to develop a water resources protection strategy at the permanent disposal sites. Finally, the plan describes ongoing activities that are in various stages of development at UMTRA sites (long-term care at disposal sites and groundwater restoration at processing sites). This plan will be reviewed annually and updated every 3 years in accordance with DOE Order 5400.1

    Full Text Available In order to maintain ecosystems and biodiversity, Australia has long invested in the development of marine and terrestrial protected area networks. Within this land- and sea-scape, northern Australia represents a global population stronghold for four species of the world’s most threatened marine fish family, the sawfishes (family Pristidae. The distribution of sawfishes across northern Australia has previously only been coarsely estimated, and the adequacy of their representation in protected areas has not been evaluated. The calculated range of each species was intersected with Australia’s marine and terrestrial protected area datasets, and targets of 10% marine and 17% inland range protection were used to determine adequacy of sawfish range protection. Marine targets have been achieved for all species, but the inland range protection targets have not been met for any species. Results indicate that further protection of inland habitats is required in order to improve sawfish protection and habitat connectivity.

    An increasing number of radiation protection experts and of professionally exposed workers is temporarily or permanently working in a country other than the one where they received their radiation protection education or training. They all face the problem and the difficulties of recognition of radiation protection training programs by other countries. For this reason the German-Swiss Radiation Protection Association (Fachverband fuer Strahlenschutz; FS) made a proposal to IRPA for an action on the mutual recognition of radiation protection education in Europe. In a first step contacts were made with two other European Associations of France and UK in order to establish a joint working group. (orig.) [de

    2006-12-07

    Effective health protection requires systematised responses with clear accountabilities. In England, Primary Care Trusts and the Health Protection Agency both have statutory responsibilities for health protection. A Memorandum of Understanding identifies responsibilities of both parties, but there is a potential lack of clarity about responsibility for specific health protection functions. We aimed to investigate professionals' perceptions of responsibility for different health protection functions, to inform future guidance for, and organisation of, health protection in England. We sent a postal questionnaire to all health protection professionals in England from the following groups: (a) Directors of Public Health in Primary Care Trusts; (b) Directors of Health Protection Units within the Health Protection Agency; (c) Directors of Public Health in Strategic Health Authorities and; (d) Regional Directors of the Health Protection Agency The response rate exceeded 70%. Variations in perceptions of who should be, and who is, delivering health protection functions were observed within, and between, the professional groups (a)-(d). Concordance in views of which organisation should, and which does deliver was high (> or =90%) for 6 of 18 health protection functions, but much lower (protection function was strongly correlated with the concordance (r = 0.65, P = 0.0038). Whilst we studied professionals' perceptions, rather than actual responses to incidents, our study suggests that there are important areas of health protection where consistent understanding of responsibility for delivery is lacking. There are opportunities to clarify the responsibility for health protection in England, perhaps learning from the approaches used for those health protection functions where we found consistent perceptions of accountability.

    Full text of publication follows: A number of industrial applications and public services involve exposure to ultraviolet radiation (U.V.R.) from a variety of lamps and lasers, for example, in forensic examination, biological trans-illuminators, dentistry, laser material processing, microelectronics, etc. The proposed European Union Directive on Optical Radiation would place specific requirements on employers to provide adequate safety measures to reduce exposure to U.V.R., including gloves for hand protection. The selection of gloves should be based on a risk assessment and on the performance characteristics of the gloves for the task. However, current International and national standards do not describe evaluation procedures of disposable gloves for hand protection against non-ionising radiation. A methodology for assessment of the UV protection level for disposable gloves and a simple measurement protocol are proposed, based on a common approach with UV protection by clothing and sunscreens. Glove Ultraviolet Protection Factor is defined as a time-scale increase in exposure permitted for the hand protected by a glove with respect to an unprotected hand. However, the wide variety of U.V.R. sources and the real-life conditions of glove use (stretching and wetting the surface by liquids) bring substantial challenges to the assessment method. Our study of ∼ 50 samples of widely used disposable gloves made of different materials (nitrile, vinyl, latex and chloroprene) showed that for all tested gloves a change in U.V.R. attenuation with stretching is characteristic for the type of glove material and can be included as a scaling factor in the definition of U.V.R. protection. Glove material has a bigger effect on U.V.R. protection level than variations in the glove thickness or its colour. The following approaches are suggested to overcome the problem of variable U.V.R. sources: - Worst case scenario minimal protection level, most restrictive case - Application

  7. Physical protection system design and evaluation

    Williams, J.D.

    1997-01-01

    The design of an effective physical protection system includes the determination of physical protection system objectives, initial design of a physical protection system, design evaluation, and probably a redesign or refinement. To develop the objectives, the designer must begin by gathering information about facility operation and conditions, such as a comprehensive description of the facility, operating conditions, and the physical protection requirements. The designer then needs to define the threat. This involves considering factors about potential adversaries: class of adversary, adversary's capabilities, and range of adversary's tactics. Next, the designer should identify targets. Determination of whether or not the materials being protected are attractive targets is based mainly on the ease or difficulty of acquisition and desirability of the material. The designer now knows the objectives of the physical protection system, that is, open-quotes what to protect against whom.close quotes The next step is to design the system by determining how best to combine such elements as fences, vaults, sensors and assessment devices, entry control elements, procedures, communication devices, and protective forces personnel to meet the objectives of the system. Once a physical protection system is designed, it must be analyzed and evaluated to ensure it meets the physical protection objectives. Evaluation must allow for features working together to ensure protection rather than regarding each feature separately. Due to the complexity of the protection systems, an evaluation usually requires modeling techniques. If any vulnerabilities are found, the initial system must be redesigned to correct the vulnerabilities and a reevaluation conducted. This paper reviews the physical protection system design and methodology mentioned above. Examples of the steps required and a brief introduction to some of the technologies used in modem physical protections system are given

    Occupational exposure to ionizing radiation can occur in a range of industries, medical institutions, educational and research establishments and nuclear fuel cycle facilities. Adequate radiation protection of workers is essential for the safe and acceptable use of radiation, radioactive materials and nuclear energy. In 1996, the Agency published Safety Fundamentals on Radiation Protection and the Safety of Radiation Sources (IAEA Safety Series No. 120) and International Basic Safety Standards for Protection against Ionizing, Radiation and for the Safety of Radiation Sources (IAEA Safety Series No. 115), both of which were jointly sponsored by the Food and Agriculture Organization of the United Nations, the IAEA, the International Labour Organisation, the OECD Nuclear Energy Agency, the Pan American Health Organization and the World Health Organization. These publications set out, respectively, the objectives and principles for radiation safety and the requirements to be met to apply the principles and to achieve the objectives. The establishment of safety requirements and guidance on occupational radiation protection is a major component of the support for radiation safety provided by the IAEA to its Member States. The objective of the IAEA's occupational protection programme is to promote an internationally harmonized approach to the optimization of occupational radiation protection, through the development and application of guidelines for restricting radiation exposures and applying current radiation protection techniques in the workplace. Guidance on meeting the requirements of the Basic Safety Standards for occupational protection is provided in three interrelated Safety Guides, one giving general guidance on the development of occupational radiation protection programmes and two giving more detailed guidance on the monitoring and assessment of workers' exposure due to external radiation sources and from intakes of radionuclides, respectively.

    Using a questionnaire we investigated whether radiation protection is correctly understood by medical doctors (n=140) and nurses (n=496). Although medical exposure is usually understood by medical doctors and dentists, their knowledge was found to be insufficient. Sixty-eight percent of medical doctors and 50% of dentists did not know about the system of radiation protection. Dose monitoring was not correctly carried out by approximately 20% of medical staff members, and medical personnel generally complained of anxiety about occupational exposure rather than medical exposure. They did not receive sufficient education on radiation exposure and protection in school. In conclusion, the results of this questionnaire suggested that they do not have adequate knowledge about radiation exposure and protection. The lack of knowledge about protection results in anxiety about exposure. To protect oneself from occupational exposure, individual radiation doses must be monitored, and medical practice should be reconsidered based on the results of monitoring. To eliminate unnecessary medical and occupational exposure and to justify practices such as radiological examinations, radiation protection should be well understood and appropriately carried out by medical doctors and dentists. Therefore, the education of medical students on the subject of radiation protection is required as is postgraduate education for medical doctors, dentists and nurses. (author)

    Uranium in atmospheric conditions is non-stable. Sloughing products are being generated on its surface during storage or use. These corrosion products make many difficulties because of necessity to provide personnel safety. Besides, uranium corrosion may cause damage in parts. The first works devoted to uranium corrosion were performed in the framework of the USA Manhattan Project in the early forties of last century. Various methods of uranium protection were investigated, among them the galvanic one was the most studied. Later on the galvanic technology was patented. The works on this problem remains urgent up to the present time. In Russia, many methods of uranium corrosion protection, mainly against atmospheric corrosion, were tried on. In particular, such methods as diffusion zinc and paint coating were investigated. In the first case, a complex intermetallic U-Zn compound was formed but its protection was not reliable enough, this protection system was inconvenient and uncertain and that is why an additional paint coating was necessary. In the case of paint coatings another problem appeared. It was necessary to find such a coating where gas-permeability would prevail over water-permeability. Otherwise significant uranium corrosion occurs. This circumstance together with low mechanical resistance of paint coatings does not allow to use paint coating for long-term protection of uranium. Currently, there are following methods of uranium protection: ion-plasma, galvanic and thermo-vacuum annealing. These are described in this paper. In the end the issue of corrosion protection in reactor core zones is addressed. Here the greatest difficulties are caused when enriched uranium heated up to 500 deg. C needs anticorrosion protection. In this case various metal coatings are not reliable because of brittle inter-metallide formation. The reliable protection may be provided only up to the temperature plus 400 - 500 deg. C with the help of galvanic copper coating since

    Safety culture or radiation protection culture is based in common on the term, 'culture'. Culture is defined as the learned, shared set of symbols and patterns of basic assumptions, which is invented, discovered, or developed by a given group as it learns to cope with its problem of external adaptation and internal integration. Safety culture generally refers to the attitude and behaviors affecting safety performance. The concept of 'Safety Culture' was introduced after the Chernobyl accident in 1986. For the accident, nuclear society reached the conclusion that the cause was the wrong management attitude of the NPP, that is, deficient 'Safety Culture'. Recently, 'Radiation Protection Culture' was introduced as the core concept of nuclear safety culture. There have been many efforts to establish definition and develop assessment tool for radiation protection culture in international level such as ICRP and IRPA as well as NRC. In the same context with the safety culture, radiation protection culture is defined as 'the core values and behaviors resulting from a collective commitment by leaders and individual's to emphasize safety over competing goals to ensure protection of people and the environment.' It is worthwhile to recognize that regulatory enforcement in establishing healthy radiation protection culture of operators should be minimized because culture is not in the domain of regulatory enforcement. However, as 'ALARA', the most important concept in radiation protection, may be successfully achieved only in well established radiation protection culture, the least regulatory intervention would be needed in promoting and nurturing radiation protection culture in licensee. In addition, the concept of radiation protection culture should be addressed in plant operational policy to achieve the goals of ALARA.

    The US Department of Homeland Security (DHS) has directed its Protective Security Advisors (PSAs) to form partnerships with the owners and operators of assets most essential to the Nation's well being - a subclass of critical infrastructure and key resources (CIKR) - and to conduct site visits for these and other high-risk assets as part of the Enhanced Critical Infrastructure Protection (ECIP) Program. During each such visit, the PSA documents information about the facility's current CIKR protection posture and overall security awareness. The primary goals for ECIP site visits (DHS 2009) are to: (1) inform facility owners and operators of the importance of their facilities as an identified high-priority CIKR and the need to be vigilant in light of the ever-present threat of terrorism; (2) identify protective measures currently in place at these facilities, provide comparisons of CIKR protection postures across like assets, and track the implementation of new protective measures; and (3) enhance existing relationships among facility owners and operators; DHS; and various Federal, State, local tribal, and territorial partners. PSAs conduct ECIP visits to assess overall site security; educate facility owners and operators about security; help owners and operators identify gaps and potential improvements; and promote communication and information sharing among facility owners and operators, DHS, State governments, and other security partners. Information collected during ECIP visits is used to develop metrics; conduct sector-by-sector and cross-sector vulnerability comparisons; identify security gaps and trends across CIKR sectors and subsectors; establish sector baseline security survey results; and track progress toward improving CIKR security through activities, programs, outreach, and training (Snyder 2009). The data being collected are used in a framework consistent with the National Infrastructure Protection Plan (NIPP) risk criteria (DHS 2009). The

    Full Text Available Tutelle réelle de l’embryon signifie protection effective sur la base du droit positif en vigueur. L’étude cherche à affirmer que l’embryon humain est un objet sous tutelle, établi par l’ordre juridique. Elle conteste que l’embryon soit titulaire de droits subjectifs et donc qu’il puisse acquérir la qualification juridique de personne. La signification du terme de vie est conceptuellement différente au sens biologique et au sens juridique. Les Codes civils européens assignent la capacité juridique au fœtus qui est né vivant. Avant cet instant, le système juridique est en mesure d’accorder une protection à l’embryon toutefois différente de la norme qui protège la vie humaine de la personne déjà née. Bref, la protection de l’embryon est indépendante de sa qualification comme sujet.Real protection means effective protection through existing positive law. The article attempts to demonstrate that the embryo is an object entitled to a safeguards attributed by the law to human life as such. It denies that the embryo has subjective rights and therefore can acquire the legal qualification of subject of law or a person. The meaning of the concept of life is different, be it from the biological or legal point of view. European civil codes give legal capacity to the foetus who was born alive. Before this moment, the legal system has the possibility to give protection to the embryo but this protection is different from the norm protecting human life of an already born person. Consequently the protection of the embryo is independent from the qualification of the embryo as a subject.

    The aim of radiation protection is to avoid or to reduce the risks linked to ionizing radiation. In order to reduce these risks, the radiation protection uses three great principles: justification, optimization and limitation of radiation doses. to apply these principles, the radiation protection has regulatory and technical means adapted to three different categories of people: public, patients and workers. The nuclear safety authority elaborates the regulation, and carries out monitoring of the reliable application of radiation protection system. (N.C.)

    1993-01-01

    The effects of radiation on non-human species, both animals and plants, have long been investigated. In the disposal of radioactive wastes, the protection of non-human species has been investigated. Yet no radiation protection standard for exposure of animals and plants per se has been agreed. The International Commission on Radiological Protection has long taken the view that, if human beings are properly protected from radiation, other species will thereby be protected to the extent necessary for their preservation. However, the International Atomic Energy Agency has found it necessary to investigate the protection of non-human species where radioactivity is released to an environment unpopulated by human beings. It is proposed that the basis of such protection, and the knowledge of radiation effects on non-human species on which it is based, suggest a practical radiation protection standard for non-human species.

  14. On population growth near protected areas.

    Directory of Open Access Journals (Sweden)

    Lucas N Joppa

    Full Text Available Protected areas are the first, and often only, line of defense in efforts to conserve biodiversity. They might be detrimental or beneficial to rural communities depending on how they alter economic opportunities and access to natural resources. As such, protected areas may attract or repel human settlement. Disproportionate increases in population growth near protected area boundaries may threaten their ability to conserve biodiversity.Using decadal population datasets, we analyze population growth across 45 countries and 304 protected areas. We find no evidence for population growth near protected areas to be greater than growth of rural areas in the same country. Furthermore, we argue that what growth does occur near protected areas likely results from a general expansion of nearby population centers.Our results contradict those from a recent study by Wittemyer et al., who claim overwhelming evidence for increased human population growth near protected areas. To understand the disagreement, we re-analyzed the protected areas in Wittemyer et al.'s paper. Their results are simply artifacts of mixing two incompatible datasets. Protected areas may experience unusual population pressures near their edges; indeed, individual case studies provide examples. There is no evidence, however, of a general pattern of disproportionate population growth near protected areas.

    Purpose: To previously set a nuclear reactor toward safety side by the reactor scram if an emergency core cooling system is failed to operate. Constitution If abnormality occurs in an emergency core cooling system or an aqueous boric acid injection system, a reactor protection system is operated and, if the reactor protection system shows an abnormal state, a control rod withdrawal inhibition system is operated as a fundamental way. For instance, when the driving power source voltage for the emergency core cooling system is detected and, if it is lower than a predetermined value, the reactor protection system is operated. Alternatively, if the voltage goes lower than the predetermined value, the control rod withdrawal is inhibited. In addition, stopping for the feedwater system is inhibited. Further, integrity of the driving means for the emergency core cooling system is positively checked and the protection function is operated depending on the result of check. Since the nuclear reactor can be set toward the safety side even if the voltage for the driving power source of the aqueous boric acid injection system is lower than a predetermined value, the reactor safety can further be improved.

    Purpose: Previously, the diagnostic radiological index of protection (DRIP) was proposed as a metric for quantifying the protective value of radioprotective garments. The DRIP is a weighted sum of the percent transmissions of different radiation beams through a garment. Ideally, the beams would represent the anticipated stray radiation encountered during clinical use. However, it is impractical to expect a medical physicist to possess the equipment necessary to accurately measure transmission of scattered radiation. Therefore, as a proof of concept, the authors tested a method that applied the DRIP to clinical practice. Methods: Primary beam qualities used in interventional cardiology and radiology were observed and catalogued. Based on the observed range of beam qualities, five representative clinical primary beam qualities, specified by kV and added filtration, were selected for this evaluation. Monte Carlo simulations were performed using these primary beams as source definitions to generate scattered spectra from the clinical primary beams. Using numerical optimization, ideal scatter mimicking primary beams, specified by kV and added aluminum filtration, were matched to the scattered spectra according to half- and quarter-value layers and spectral shape. To within reasonable approximation, these theoretical scatter-mimicking primary beams were reproduced experimentally in laboratory x ray beams and used to measure transmission through pure lead and protective garments. For this proof of concept, the DRIP for pure lead and the garments was calculated by assigning equal weighting to percent transmission measurements for each of the five beams. Finally, the areal density of lead and garments was measured for consideration alongside the DRIP to assess the protective value of each material for a given weight. Results: The authors identified ideal scatter mimicking primary beams that matched scattered spectra to within 0.01 mm for half- and quarter-value layers in

  18. DOE Standard: Fire protection design criteria

    International Nuclear Information System (INIS)

    1999-07-01

    The development of this Standard reflects the fact that national consensus standards and other design criteria do not comprehensively or, in some cases, adequately address fire protection issues at DOE facilities. This Standard provides supplemental fire protection guidance applicable to the design and construction of DOE facilities and site features (such as water distribution systems) that are also provided for fire protection. It is intended to be used in conjunction with the applicable building code, National Fire Protection Association (NFPA) Codes and Standards, and any other applicable DOE construction criteria. This Standard replaces certain mandatory fire protection requirements that were formerly in DOE 5480.7A, ''Fire Protection'', and DOE 6430.1A, ''General Design Criteria''. It also contains the fire protection guidelines from two (now canceled) draft standards: ''Glove Box Fire Protection'' and ''Filter Plenum Fire Protection''. (Note: This Standard does not supersede the requirements of DOE 5480.7A and DOE 6430.1A where these DOE Orders are currently applicable under existing contracts.) This Standard, along with the criteria delineated in Section 3, constitutes the basic criteria for satisfying DOE fire and life safety objectives for the design and construction or renovation of DOE facilities

    In the framework of the French regulation on nuclear materials possession, the first liability is the one of operators who have to know at any time the quantity, quality and localization of any nuclear material in their possession. This requires an organization of the follow up and of the inventory of these materials together with an efficient protection against theft or sabotage. The French organization foresees a control of the implementation of this regulation at nuclear facilities and during the transport of nuclear materials by the minister of industry with the sustain of the institute of radiation protection and nuclear safety (IRSN). This article presents this organization: 1 - protection against malevolence; 2 - national protection and control of nuclear materials: goals, administrative organization, legal and regulatory content (authorization, control, sanctions), nuclear materials protection inside facilities (physical protection, follow up and inventory, security studies), protection of nuclear material transports (physical protection, follow up), control of nuclear materials (inspection at facilities, control of nuclear material measurements, inspection of nuclear materials during transport); 3 - international commitments of France: non-proliferation treaty, EURATOM regulation, international convention on the physical protection of nuclear materials, enforcement in France.

  1. Using the 'protective environment' framework to analyse children's protection needs in Darfur.

    Ager, Alastair; Boothby, Neil; Bremer, Megan

    2009-10-01

    A major humanitarian concern during the continuing crisis in Darfur, Sudan, has been the protection of children, although there has been little in the way of comprehensive analysis to guide intervention. Founded on a situational analysis conducted between October 2005 and March 2006, this paper documents the significant threats to children's well-being directly linked to the political conflict. It demonstrates the role of non-conflict factors in exacerbating these dangers and in promoting additional protection violations, and it uses the 'protective environment' framework (UNICEF Sudan, 2006a) to identify systematic features of the current environment that put children at risk. This framework is shown to provide a coherent basis for assessment and planning, prompting broad, multidisciplinary analysis, concentrating on preventive and protective action, and fostering a systemic approach (rather than placing an undue focus on the discrete needs of 'vulnerable groups'). Constraints on its present utility in emergency settings are also noted.

  2. The Protection of Animals in Thailand--An Insight into Animal Protection Legislation

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available There are many critics of current Thai law concerning the welfare of animals. They argue that the PACPAWA,2014 is inadequate to protect the welfare of animals. The absence of clear guidelines in the legislation concerning animal welfare has resulted in animal welfare receiving inadequate protection. There are other limitations contributing to the inadequacy of existing laws in protecting animals in Thailand. The possible penalties are very low. For the offence of cruelty against an animal, the PACPAWA,2014 sets a maximum fine of TBH 2000. This is considered inadequate and ineffective in preventing cruelty to animals. The study utilises doctrinal legal research or library-based research approach to provide valuable insights in understanding the law and and ascertaining the principles of legal interpretation and analysis. The study also provides possible suggestions to enhance the protection of the welfare of animals in Thailand. The research suggests that education should play an important role in promoting kindness towards animals.

    Radiation protection records are a fundamental part of any program for protecting radiation workers. Records are essential to epidemiological studies of radiation workers and are becoming increasingly important as the number of radiation exposure litigation cases increases. Ready retrievability of comprehensive records is also essential to the adequate defense of a radiation protection program. Appraisals of numerous radiation protection programs have revealed that few record-keeping systems comply with American National Standards Institute, Standard Practice N13.6-1972. Record-keeping requirements and types of deficiencies in radiation protection records systems are presented in this paper, followed by general recommendations for implementing a comprehensive radiation protection records system

    Full text: People are exposed to ionizing radiation in many different forms: cosmic rays that penetrate earth atmosphere or radiation from soil and mineral resources are natural forms of ionizing radiation. Other forms are produced artificially using radioactive materials for various beneficial applications in medicine, industry and other fields. The greatest concerns about ionizing radiation are tied to its potential health effects and a system of radiation protection has been developed to protect people from harmful radiation. The promotion of radiation protection is one of the International Atomic Energy Agency main activities. Radiation protection concerns the protection of workers, members of public, and patients undergoing diagnosis and therapy against the harmful effects of ionizing radiation. The report covers the responsibility of radiation protection officer in Egypt Second Research Reactor (ETRR-2) in Inshas - Egypt, also presents the protection against ionizing radiation from external sources, including types of radiation, sources of radiation (natural - artificial), and measuring units of dose equivalent rate. Also covers the biological effects of ionizing radiation, personal monitoring and radiation survey instruments and safe transport of radioactive materials. The report describes the Egypt Second Research Reactor (ETRR-2), the survey instruments used, also presents the results obtained and gave a relations between different categories of data. (author)

  10. Concepts in radiation protection

    International Nuclear Information System (INIS)

    Oncescu, M.

    1996-01-01

    This monograph provides basic notions and principles in dosimetry and radiation protection in compliance with two fundamental works: IAEA Safety Series No.115 - International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources - and Publication no. 60 of International Commission on Radiological Protection. After the review of quantities and units necessary in radiation protection, the book presents the new values of dose limits as well as the values of 'radiation weighting factor', 'tissue weighting factor' and 'conversion factor intake-dose' (committed effective dose per unit intake) by ingestion and inhalation for 30 most important radionuclides. The new values of dose limits, lower than the old values, are a challenge for the radiation protection, especially of the 'public' where the dose limit diminished by a factor of five relative to the earlier edition. The new value of dose limit for public, 1 mSv per year (obviously over the natural exposure of 2.4 mSv per year), imposes new action ways and levels in radiation protection, especially in some cases of exacerbated natural radioactivity. The book provides the calculus of external exposure with the Gamma constant expressed in adequate units, to make the calculation easier. In the calculus of protection shield for gamma sources one uses a method, which while approximate helps save time. The calculus of internal exposure is made using the conversion factor intake-dose. Finally, the 'dosimetric watch' of the natural and artificial radioactivity of the atmosphere, hydrosphere and biosphere is intended to comply with the International Basic Safety Standards. Each chapter ends with a set of illustrative problems which enhances the reader's understanding of underlying concepts and current methods used in the field

    Directory of Open Access Journals (Sweden)

    Horsley Stephen S

    2006-12-01

    Full Text Available Abstract Background Effective health protection requires systematised responses with clear accountabilities. In England, Primary Care Trusts and the Health Protection Agency both have statutory responsibilities for health protection. A Memorandum of Understanding identifies responsibilities of both parties, but there is a potential lack of clarity about responsibility for specific health protection functions. We aimed to investigate professionals' perceptions of responsibility for different health protection functions, to inform future guidance for, and organisation of, health protection in England. Methods We sent a postal questionnaire to all health protection professionals in England from the following groups: (a Directors of Public Health in Primary Care Trusts; (b Directors of Health Protection Units within the Health Protection Agency; (c Directors of Public Health in Strategic Health Authorities and; (d Regional Directors of the Health Protection Agency Results The response rate exceeded 70%. Variations in perceptions of who should be, and who is, delivering health protection functions were observed within, and between, the professional groups (a-(d. Concordance in views of which organisation should, and which does deliver was high (≥90% for 6 of 18 health protection functions, but much lower (≤80% for 6 other functions, including managing the implications of a case of meningitis out of hours, of landfill environmental contamination, vaccination in response to mumps outbreaks, nursing home infection control, monitoring sexually transmitted infections and immunisation training for primary care staff. The proportion of respondents reporting that they felt confident most or all of the time in the safe delivery of a health protection function was strongly correlated with the concordance (r = 0.65, P = 0.0038. Conclusion Whilst we studied professionals' perceptions, rather than actual responses to incidents, our study suggests that there

  12. Can Nature Protection be Unsustainable? Models Behind Nature Protection in New Zealands National Parks

    Science.gov (United States)

    Hauhs, Michael; Bogner, Christina

    2013-04-01

    Nature protection can be justified by intrinsic values of life. Western culture sees nature as an autonomous system. Thus, nature protection is often synonymous with refraining from human interference as much as possible. This, however, can pose at least technical problems. Indeed, historical human impacts such as introduced species are often irreversible. In such cases refraining from human interference to protect threatened species is not an adequate management response. Nature protection in New Zealand is a prominent example. Many introduced species make a non-interventionist attitude infeasible to protect endemic species such as kiwis. Actually, active human interference is necessary to attain this goal. Therefore, one may consider nature protection as another form of land use. As any other form of land use, it needs standards of proper management (i.e. explicit goals, assessment, intervention etc.). In other words, it has to be shown to be sustainable. However, sustainability may rigorously be defined as an attribute of past land use only. Instantaneous positive indicators of sustainability may be elusive. At best it can be decided by observation whether or not a land use has been (not) sustainable until now. Stakeholders of nature protection have often different (implicit) concepts or models of nature in mind. This can lead to conflicts when it comes to management decisions. For example, the methods by which conservationists in New Zealand seek to re-establish historical species assemblages (e.g. aerial drop of poison into national parks) have come under criticism of animal rights groups as non-humane. We propose to use abstract modelling language to classify these concepts of nature protection and related issues. We show that from modelling perspective these conflicts pose a basic science problem rather than an applied science problem. This makes the delegation into existing disciplines so hard. We discuss possible implications for nature protection

    Latorre, V.R.; Spogen, L.R. Jr.

    1974-01-01

    The protection of an electronic/electrical system from an electromagnetic environment requires a systematic approach and a clear and concise identification of the data requirements and tools (analytical and experimental) for the vulnerability assessment. In this paper, a basic protection engineering concept is developed. The concept is general and therefore applicable to many systems. It consists of five stages: (1) systems analysis, (2) subsystem degradation, (3) interaction and coupling, (4) protection trade-off analysis, and (5) fabrication and operation. A detailed discussion of all functions performed in each stage is described; the input data to these functions identified; and means (tools) by which the functional operations are satisfied are summarized. Simple examples are used throughout the paper to illustrate the definitions of various functions and to emphasize the iterative process required in arriving at a protection scheme. (U.S.)

  16. Application of radiological protection measures to meet different environmental protection criteria

    Copplestone, D.

    2012-01-01

    The International Commission on Radiological Protection (ICRP) recognises that there is no simple or single universal definition of ‘environmental protection’, and that the concept differs from country to country and from one circumstance to another. However, there is an increasing need to be able to demonstrate that the environment is protected from radioactive substances released under authorisation for various reasons, such as for wildlife conservation requirements, or wildlife management for commercial reasons, or simply as part of pollution control. The Commission is developing the concept of Representative Organisms, which may be identified from any specific legal requirements or from more general requirements to protect local habitats or ecosystems. Such organisms may be the actual objects of protection or they may be hypothetical, depending on the objectives of the assessment. They may be similar to, or even congruent with, one or more of the Reference Animals and Plants (RAPs). Where this is not the case, attempts can be made to consider the extent to which the Representative Organisms differ from the nearest RAP in terms of known radiation effects upon it, basic biology, radiation dosimetry, and pathways of exposure. This paper discusses the practical implications of such an approach.

  4. New regulations foster wellhead protection efforts

    International Nuclear Information System (INIS)

    Lennox, J.

    1993-01-01

    Groundwater contamination can have disastrous consequences: closed wellfields, insufficient temporary water supplies, and costly, prolonged clean-up. Realizing that it is more prudent to protect water wells than to wait for contamination to occur, many states are issuing regulations designed to protect the surface and subsurface areas surrounding public water system wells. The states have been prompted in part by the federal Safe Drinking Water Act Amendments of 1986, which provide grants and technical guidance to state wellhead protection programs. The Act does not impose regulations itself, but leaves it to the states to create and manage protection programs. Accordingly, regulations may differ dramatically from state to state, reflecting distinct hydrogeology and land uses. In every program, however, the starting point is the determination of wellhead protection areas. The protection area can range from a few hundred feet to several miles from a well. The characteristics of the aquifers surrounding the well and the amount of pumping are factors in delineating the protected area's boundaries. This article examines methods for determining the protection area

    2007-01-01

    In food occupations, like in many other skin risk occupations, the regular use of personal protection equipment, i.e. of skin protection ointments and protective gloves, is recommended as well as regular skin care for the prevention of occupational hand dermatitis. We investigated the uptake and maintenance of different prevention strategies (instructions for skin protection and skin care, prevocational skin hardening with UV light) in food occupations and their efficacy in the primary prevention of vocationally caused hand dermatitis. We could show that the acceptance and regular use of skin protection and care measures could be significantly increased by theoretical and practical instructions in food industry trainees. The highest acceptance was seen with skin protection ointment (100%) and skin care (90%). Protective gloves (43.3%) were used to a lesser extent. The hand dermatitis point prevalence in the groups after 6 months was 13.3% (skin protection), 19.4% (UV hardening) and 29.1% (controls). These clinical trends were supported by statistically significant differences in the basal TEWL values. Adequate skin protection and regular skin care seem to be promising for the prevention of occupationally caused hand dermatitis. The experimental approach using UV hardening prevocationally did not fulfil the expectations.

    Rare evidences support that Marine Protected Areas (MPAs) enhance the stability of marine habitats and assemblages. Based on nine years of observation (2001-2009) inside and outside a well managed MPA, we assessed the potential of conservation and management actions to modify patterns of spatial and/or temporal variability of Posidonia oceanica meadows, the lower midlittoral and the shallow infralittoral rock assemblages. Significant differences in both temporal variations and spatial patterns were observed between protected and unprotected locations. A lower temporal variability in the protected vs. unprotected assemblages was found in the shallow infralittoral, demonstrating that, at least at local scale, protection can enhance community stability. Macrobenthos with long-lived and relatively slow-growing invertebrates and structurally complex algal forms were homogeneously distributed in space and went through little fluctuations in time. In contrast, a mosaic of disturbed patches featured unprotected locations, with small-scale shifts from macroalgal stands to barrens, and harsh temporal variations between the two states. Opposite patterns of spatial and temporal variability were found for the midlittoral assemblages. Despite an overall clear pattern of seagrass regression through time, protected meadows showed a significantly higher shoot density than unprotected ones, suggesting a higher resistance to local human activities. Our results support the assumption that the exclusion/management of human activities within MPAs enhance the stability of the structural components of protected marine systems, reverting or arresting threat-induced trajectories of change.

    1974-01-01

    The manual as a whole deals with the radiation protection of patients, occupationally exposed persons, and the public. Volume 1, on basic protection requirements, is a general review common to all medical applications of ionizing radiation and radionuclides. Radiation protection is required for patients and staff, and with regard to medical research and chemical trials of new methods; radiation equipment and operating procedures are discussed in connection with diagnostic x-ray installations, x-ray beam therapy, gamma-ray installations for teletherapy, brachytherapy, unsealed sources for therapeutic use, and the diagnostic use of unsealed sources in nuclear medicine. In planning of radiation facilities, attention is paid to levels at which medical care is given, the centralization and decentralization of radiation facilities, diagnostic x-ray facilities and therapy facilities, and nuclear medicine and therapy with unsealed sources. Shielding design is discussed applicable to diagnostic radiology, radiotherapy, nuclear medicine and the therapeutic use of radionuclides. Assignment of responsibilities, legal responsibilities, safety checks, refresher courses and symposia are discussed in the context of organizing radiation protection. Radiation surveys are necessary, and such surveys are described for x-ray and gamma-ray beams, sealed radioactive sources and nuclear medicine. A whole section is devoted to personnel monitoring and health surveillance. An annex gives a list of commonly used radionuclides, another deals with the design of protective shielding

    2002-01-01

    Greek Atomic Energy Commission (GAEC) is the regulatory, advisory and competent authority on radiation protection matters. It is the authority responsible for the introduction of Radiation Protection regulations and monitoring of their implementation. In 1997, within the frame of its responsibilities the Board of the GAEC appointed a task group of experts to revise and bring the present Radiation Protection Regulations into line with the Basic Safety Standards (BSS) 96/29/Euratom Directive and the 97/43/Euratom Directive (on health protection of individuals against the dangers of ionising radiation in relation to medical exposure). Concerning the Title 7. of the new European BSS Directive, which refers to the Radiation Protection at work places with increased levels of natural radiation exposure, the Radiation Protection Regulations provides that the authority responsible for recording, monitoring and introducing protection measures at these places is the GAEC. Practices where effective doses to the workers due to increased natural radiation levels, may exceed 1mSv/y, have to be specified and authorised by the GAEC. The identification procedure is ongoing

    Serious concern about physical protection of nuclear facilities began around 1972. R and D was initiated at Sandia National Laboratories which had developed techniques to protect weapons for many years. Special vehicles, convoy procedures, and a communications system previously developed for weapons shipments were improved and extended for shipments of other sensitive materials. Barriers, perimeter alarms, portal and internal control systems were developed, tested, and published in handbooks and presented at symposia. Training programs were initiated for U.S. and foreign personnel. Containment and surveillance techniques were developed for the IAEA. Presently emphasis is on computer security, active barriers, and techniques to prevent theft or sabotage by ''insiders''

    Radiation sources are widely used in medicine, industry, research and education in Madagascar. Safety and security of these sources are the main statutory functions of the Regulatory Authority as defined by the regulations in Radiation Protection in Madagascar. These functions are carried out through the system of notification, authorization and inspection, inventory of radiation source and emergency preparedness. The law no 97-041 on radiation protection and radioactive waste management in Madagascar was promulgated on 2nd January 1998. It governs all activities related to the peaceful use of nuclear energy in Madagascar in order to protect the public, the environment and for the safety of radiation sources. This law complies with the International Basic Safety Standards for protection against ionising Radiation and for the Safety of Radiation Sources (BSS, IAEA Safety Series no 115). Following the promulgation of the law, four decrees have been enacted by the Malagasy Government. With an effective implementation of these decrees, the ANPSR will be the Highest Administrative Authority in the Field of Radiation Protection and Waste Management in Madagascar. This Regulatory Authority is supported by an Executive Secretariat, assisted by the OTR for Radiation Protection and the OCGDR for Managing Radioactive Waste.The paper includes an overview of the regulatory infrastructure and the organizations of radiation protection in Madagascar

  20. Effect of Remote Back-Up Protection System Failure on the Optimum Routine Test Time Interval of Power System Protection

    Directory of Open Access Journals (Sweden)

    Y Damchi

    2013-12-01

    Full Text Available Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote back-up protection system was considered fully reliable. This assumption is not exactly correct since remote back-up protection system may operate incorrectly or fail to operate, the same as the primary protection system. Therefore, in order to determine the ORTTI, an extended Markov model is proposed in this paper considering failure probability for remote back-up protection system. In the proposed Markov model of the protection systems, monitoring facility is taken into account. Moreover, it is assumed that the primary and back-up protection systems are maintained simultaneously. Results show that the effect of remote back-up protection system failures on the reliability indices and optimum routine test intervals of protection system is considerable.

    Some of the major problems in radiation protection are closely connected to issues that have a long, independent tradition in moral philosophy. This contribution focuses on two of these issues. One is the relationship between the protection of individuals and optimisation on the collective level, and the other is the relative valuation of future versus immediate damage. Some of the intellectual tools that have been developed by philosophers can be useful in radiation protection. On the other hand, philosophers have much to learn from radiation protectors, not least when it comes to finding pragmatic solutions to problems that may be intractable in principle

    Science.gov (United States)

    King, A I; Yang, K H

    1995-04-01

    This paper discusses the biomechanical bases for occupant protection against frontal and side impact. Newton's Laws of Motion are used to illustrate the effect of a crash on restrained and unrestrained occupants, and the concept of ride down is discussed. Occupant protection through the use of energy absorbing materials is described, and the mechanism of injury of some of the more common injuries is explained. The role of the three-point belt and the airbag in frontal protection is discussed along with the potential injuries that can result from the use of these restraint systems. Side impact protection is more difficult to attain but some protection can be derived from the use of padding or a side impact airbag. It is concluded that the front seat occupants are adequately protected against frontal impact if belts are worn in an airbag equipped vehicle. Side impact protection may not be uniform in all vehicles.

  6. Planetary protection protecting earth and planets against alien microbes

    2006-01-01

    Protecting Earth and planets against the invasion of 'alien life forms' is not military science fiction, but it is the peaceful daily job of engineers and scientists of space agencies. 'Planetary Protection' is preventing microbial contamination of both the target planet and the Earth when sending robots on interplanetary space mission. It is important to preserve the 'natural' conditions of other planets and to not bring with robots 'earthly microbes' (forward contamination) when looking for 'spores of extra terrestrial life'. The Earth and its biosphere must be protected from potential extraterrestrial biological contamination when returning samples of other planets to the Earth (backward contamination). The NASA-Caltech Laboratory for Planetary Protection of Dr. Kasthuri Venkateswaran at the Jet Propulsion Laboratory (JPL) (California, USA) routinely monitors and characterizes the microbes of NASA spacecraft assembly rooms and space robots prior to flight. They have repeatedly isolated Cupriavidus and Ralstonia strains pre-flight from spacecraft assembly rooms (floor and air) and surfaces of space robots such as the Mars Odyssey Orbiter (La Duc et al., 2003). Cupriavidus and Ralstonia strains have also been found in-flight, in ISS cooling water and Shuttle drinking water (Venkateswaran et al., Pyle et al., Ott et al., all unpublished). The main objective of this study is to characterise the Cupriavidus and Ralstonia strains isolated at JPL and compare them to the Cupriavidus metallidurans CH34T model strain, isolated from a Belgian contaminated soil and studied since 25 years at SCK-CEN and to enhance our knowledge by performing additional tests at JPL and gathering information regarding the environmental conditions and the cleaning and isolation methods used in such spacecraft assembling facilities

    2016-01-01

    Since the discovery of radiation at the end of the 19. century, the health effects of exposure to radiation have been studied more than almost any other factor with potential effects on human health. The NEA has long been involved in discussions on the effects of radiation exposure, releasing two reports in 1994 and 2007 on radiological protection science. This report is the third in this state-of-the-art series, examining recent advances in the understanding of radiation risks and effects, particularly at low doses. It focuses on radiobiology and epidemiology, and also addresses the social science aspects of stakeholder involvement in radiological protection decision making. The report summarises the status of, and issues arising from, the application of the International System of Radiological Protection to different types of prevailing circumstances. Reports published by the NEA Committee on Radiation Protection and Public Health (CRPPH) in 1998 and 2007 provided an overview of the scientific knowledge available at that time, as well as the expected results from further research. They also discussed the policy implications that these results could have for the radiological protection system. The 2007 report highlighted challenges posed by developments in relation to medical exposure and by intentions to include the environment (i.e. non-human species), within the scope of the radiological protection system. It also addressed the need to be able to respond to a radiological terrorist attack. This report picks up on where the 1998 and 2007 reports left off, and addresses the state of the art in radiological prevention science and application today. It is divided into five chapters. Firstly, following broadly the structural topics from the 1998 and 2007 reports, the more purely scientific aspects of radiological protection are presented. These include cancer risk of low dose and dose rates, non-cancer effects and individual sensitivity. In view of the increasing

    2018-04-01

    The establishment of protected areas is a critical strategy for conserving biodiversity. Key policy directives like the Aichi targets seek to expand protected areas to 17% of Earth's land surface, with calls by some conservation biologists for much more. However, in places such as the United States, Germany, and Australia, attempts to increase protected areas are meeting strong resistance from communities, industry groups, and governments. We examined case studies of such resistance in Victoria, Australia, Bavaria, Germany, and Florida, United States. We considered 4 ways to tackle this problem. First, broaden the case for protected areas beyond nature conservation to include economic, human health, and other benefits, and translate these into a persuasive business case for protected areas. Second, better communicate the conservation values of protected areas. This should include highlighting how many species, communities, and ecosystems have been conserved by protected areas and the counterfactual (i.e., what would have been lost without protected area establishment). Third, consider zoning of activities to ensure the maintenance of effective management. Finally, remind citizens to think about conservation when they vote, including holding politicians accountable for their environmental promises. Without tackling resistance to expanding the protected estate, it will be impossible to reach conservation targets, and this will undermine attempts to stem the global extinction crisis. © 2017 Society for Conservation Biology.

  9. What is good radiation protection?

    International Nuclear Information System (INIS)

    Lorenz, B.

    2016-01-01

    Radiation protection is based on the ICRP-System with its pillars justification, limitation and optimization. From this radiation protection should be the same irrespective of the application of radiation. But radiation protection in the nuclear industry is much different from the use of radiation sources or X-ray units. This is by far not due to the different technologies. It originates from the different interpretation of the system. For one person good radiation protection would mean to have no radiation exposures, to avoid radiation at all as best option and to use it only if there are no alternatives. For another person the best radiation protection would be the one which does not produce much efforts and costs. So what is reasonable? In reality the first interpretation prevails, at least in Germany. A change is needed. If we continue to exercise radiation protection as we do it today the beneficial application of radiation will be restricted unduly and might become impossible at all. A stronger orientation towards the naturally occurring radiation would help instead to regulate natural radiation in the same way as it is done for artificial radiation. The system of ICRP has to be changed fundamentally.

  10. Protection of patients in dentistry

    International Nuclear Information System (INIS)

    Selato Selato, P.

    2013-04-01

    Current literature on dental radiology was reviewed in order to seek justification for radiological protection of patients in dental radiography, to explore the different factors affecting patient dose and to derive practical guidance on how to achieve radiological protection of patients in dentistry. Individual doses incurred in dental radiology are in general relatively low, however it is generally accepted that there is no safe level of radiation dose and that no matter how low the doses received are, there is a mathematical probability of an effect. Hence appropriate patient protection measures must be instituted to keep the exposures as low as reasonably achievable (ALARA). The literature review demonstrated that there is considerable scope for significant dose reductions in dental radiology using the techniques of optimisation of protection. The techniques of optimization of protection that can be used to ensure patient dose is as low as reasonably achievable whilst achieving clinically adequate image quality include the following: image receptor selection, image receptor holders, collimation, beam filtration, operating potential and exposure time, patient protective equipment, film exposure and processing, film storage, image viewing, quality assurance, diagnostic reference levels, technique charts and training and education.(au)

    Enhanced security measures against external threats (e.g., terrorists, criminals) have been implemented at most facilities that handle special nuclear material, classified information, or other assets critical to national security. Attention is now focusing on insider protection, and safeguards managers are attempting to provide balanced protection against insider and outsider threats. Potential insider threats include attempts by facility employees to steal special nuclear material (SNM), to cause a radiological hazard to the public, to sabotage critical facilities, or to steal property or classified information. This paper presents a report card on the status of insider protection at Department of Energy and Nuclear Regulatory Commission-licensed facilities, with emphasis on SNM theft. The authors discuss the general trends in insider protection and the limitations of protection measures currently in use. They also discuss the most critical needs for improved procedures, technology, analytical tools, and education for safeguards personnel

    The application of ionizing radiation in medicine seems to be a safe procedure for patients as well as for occupational exposition to personnel. The developments in interventional radiology with fluoroscopy and dose-intensive interventions require intensified radiation protection. It is recommended that all available tools should be used for this purpose. Besides the options for instruments, x‑ray protection at the intervention table must be intensively practiced with lead aprons and mounted lead glass. A special focus on eye protection to prevent cataracts is also recommended. The development of cataracts might no longer be deterministic, as confirmed by new data; therefore, the International Commission on Radiological Protection (ICRP) has lowered the threshold dose value for eyes from 150 mSv/year to 20 mSv/year. Measurements show that the new values can be achieved by applying all X‑ray protection measures plus lead-containing eyeglasses.

    The lecture first deals with the aims and legal basis in German and European law of environment protection with regard to energy politics. It then goes to deal with European regulations for environment protection and their effects on the energy supply: Air pollution abatement, tax for the protection of the climate, internalisation of external costs. The following European energy-political measures impinge on environment protection: Sponsored projects, least-cost planning, third-party access to the public electricity supply. The discrepancy between European and national policies can be lessened or resolved by the following means: Harmonisation, subsidiarity principle, and scope for entrepreneurial solutions. (orig.) [de

    SMART COre Protection System(SCOPS) is designed with real-tims Digital Signal Processor(DSP) board and Network Interface Card(NIC) board. SCOPS has a Control Rod POSition (CRPOS) software module while Core Protection Calculator System(CPCS) consists of Core Protection Calculators(CPCs) and Control Element Assembly(CEA) Calculators(CEACs) in the commercial nuclear plant. It's not necessary to have a independent cabinets for SCOPS because SCOPS is physically very small. Then SCOPS is designed to share the cabinets with Plant Protection System(PPS) of SMART. Therefor it's very easy to maintain the system because CRPOS module is used instead of the computer with operating system

    Switzerland's present radiation protection regulations are based on only two paragraphs of the atomic law but have been very successful in practice. A new radiation protection law, separated from nuclear legislation and valid for all application of ionizing radiation and radioctive materials, was proposed and drafted by the Federal Commission on Radiation Protection and has now been accepted by parliament with only minor modifications. The draft of the revised regulations which also will cover all applications, should be ready for consultations next year. Both the law (which contains principles but no figures such as limits) and the regulations incorporate the latest state of ICRP recommendations and are formulated in such a way as to allow application of or quick adaptation to the new basic ICRP recommendation expected for 1991. The legislation is flexible, with a relatively low regulation density and leaves sufficient room for professional judgement on a case by case basis both for authorities and for the specialists responsible for radiation protection in practice.

    The software products presented are universally usable programs for radiation protection. The systems were designed in order to establish a comprehensive database specific to radiation protection and, on this basis, model in programs subjects of radiation protection. Development initially focused on the creation of the database. Each software product was to access the same nuclide-specific data; input errors and differences in spelling were to be excluded from the outset. This makes the products more compatible with each other and able to exchange data among each other. The software products are modular in design. Functions recurring in radiation protection are always treated the same way in different programs, and also represented the same way on the program surface. The recognition effect makes it easy for users to familiarize with the products quickly. All software products are written in German and are tailored to the administrative needs and codes and regulations in Germany and in Switzerland. (orig.) [de

    A lightweight, armored protective garment for protecting an arm or leg from blast superheated gases, blast overpressure shock, shrapnel, and spall from a explosive device, such as a Rocket Propelled Grenade (RPG) or a roadside Improvised Explosive Device (IED). The garment has a ballistic sleeve made of a ballistic fabric, such as an aramid fiber (e.g., KEVLAR.RTM.) cloth, that prevents thermal burns from the blast superheated gases, while providing some protection from fragments. Additionally, the garment has two or more rigid armor inserts that cover the upper and lower arm and protect against high-velocity projectiles, shrapnel and spall. The rigid inserts can be made of multiple plies of a carbon/epoxy composite laminate. The combination of 6 layers of KEVLAR.RTM. fabric and 28 plies of carbon/epoxy laminate inserts (with the inserts being sandwiched in-between the KEVLAR.RTM. layers), can meet the level IIIA fragmentation minimum V.sub.50 requirements for the US Interceptor Outer Tactical Vest.

Dangerous zones on construction site and events to for limiting their influence or protection from the factors. Protective and catching systems is one of the most effective technical equipment, applied in recent time. Protective fences and catching systems are important part in the problem solution. Protective fences protect workers from falling from height. Protective and catching systems allows avoid injuries by workers, also catch debris, fallen from constructing buildings. In regard with continuing development in technical and technological solutions, protective and catching systems require adaptation to a new requirements of construction industry and requirements of normative documents. Technical regulations in the appliance sphere of protective and catching systems requires actualization and aligning with modern normatives. Important role should be given to developing organizational and technological documentation for application of the systems. Scientific studying of technical parameters of fences and protective catching nets also has great interest.

  4. Balancing autonomy and protection: A qualitative analysis of court hearings dealing with protective measures.

    Fallon-Kund, Marie; Coenen, Michaela; Bickenbach, Jerome E

    Respect for individual autonomy is at the core of the Convention on the Rights of Persons with Disabilities (CRPD). However, the need to protect persons with disabilities, especially those with cognitive impairments and psychosocial conditions, from outright exploitation, violence and abuse is explicitly provided for in article 16. Legal authorities still decide on a daily basis upon the institution of measures, which aim to protect vulnerable persons and unavoidably impact on the autonomy of persons concerned, known as guardianship, curatorship or administration. Observations of court hearings, interviews with judges and analysis of written materials from the cantons of Geneva and Vaud in Switzerland as well as from Belgium - which all have differently composed authorities - were carried out in order to identify what influences authorities in decision-making processes regarding protective measures, and to explore how autonomy and protection can be balanced. We suggest pragmatic considerations that should not be ignored when trying to reach a balance between autonomy and protection from abuse, in line with the CRPD. Copyright © 2017 Elsevier Ltd.

    2018-01-01

    Australia's regulatory framework has evolved over the past decade from the assumption that protection of humans implies protection of the environment to the situation now where radiological impacts on non-human species (wildlife) are considered in their own right. In an Australian context, there was a recognised need for specific national guidance on protection of non-human species, for which the uranium mining industry provides the major backdrop. National guidance supported by publications of the Australian Radiation Protection and Nuclear Safety Agency (Radiation Protection Series) provides clear and consistent advice to operators and regulators on protection of non-human species, including advice on specific assessment methods and models, and how these might be applied in an Australian context. These approaches and the supporting assessment tools provide a mechanism for industry to assess and demonstrate compliance with the environmental protection objectives of relevant legislation, and to meet stakeholder expectations that radiological protection of the environment is taken into consideration in accordance with international best practice. Experiences from the past 5-10 years, and examples of where the approach to radiation protection of the environment has been well integrated or presented some challenges will be discussed. Future challenges in addressing protection of the environment in existing exposure situations will also be discussed.

    Full Text Available According to business climate and competitiveness indicators published by international organisations, Croatia is a country with a rigid labour market and a high level of the legal protection of employees. Given that an Act on Amendments to the Labour Act (OG 73/13 entered into force in Croatia in June 2013, this paper examines changes in employment protection legislation in Croatia and Central and Eastern European (CEE countries, as well as in Croatia's main trading partners during the period between 2008 and 2013. A cross-country comparison shows a strong downward trend in legal employment protection in most CEE countries during the observed period, primarily as concerns individual dismissal in the cases of regular employment contracts, while in the case of temporary employment the protection strengthened slightly. On the other hand, despite the adoption of amendments to the Labour Act (LA, Croatian labour legislation governing employment protection for regular employment contracts remains relatively inflexible compared to that in other countries.

    Radiation protection in nuclear medicine in this project is concerned with the reduction of doses to workers, patients and members of the public. Protection of workers is achieved by adopting good personal habits, good housekeeping, proper use of personal protective devices and equipment, attend training and have continuous education. Exposure to radiation of workers and the members of the public are minimised by proper management of radioactive waste and safe transport of radioactive material. The design and shielding of a nuclear medicine department shall further provide for the protection of the worker, the patient and the general public. Protection of patient is achieved by justifying the procedure, delivering the minimum radiation dose possible to the patient while obtaining the best image quality and applying guidance levels. Special considerations shall be given to pregnant and breast-feeding patients. Quality assurance programme through image quality, radiopharmaceutical quality and patient records on nuclear medicine procedures shall provide assurance to the patient. (au)

    Full Text Available The incidence of skin cancer is increasing by epidemic proportions. Basal cell cancer remains the most common skin neoplasm, and simple excision is generally curative. On the other hand, aggressive local growth and metastasis are common features of malignant melanoma, which accounts for 75% of all deaths associated with skin cancer. The primary cause of skin cancer is long exposure to solar ultraviolet radiation (UV-R crossed with the amount of skin pigmentation and family genetics. It is believed that in childhood and adolescence, 80% of UV-R gets absorbed while in the remaining, 20 % gets absorbed later in the lifetime. This suggests that proper and early photoprotection may reduce the risk of subsequent occurrence of skin cancer. Reducing the exposure time to sunlight, using sunscreens and protective textiles are the three ways of UV protection. Most people think that all the clothing will protect them, but it does not provide full sun screening properties. Literature sources claim that only 1/3 of the spring and summer collections tested give off proper UV protection. This is very important during the summer months, when UV index is the highest. Fabric UV protection ability highly depends on large number of factors such as type of fiber, fabric surface, construction, porosity, density, moisture content, type and concentration of dyestuff, fluorescent whitening agents, UV-B protective agents (UV absorbers, as well as nanoparticles, if applied. For all of these reasons, in the present paper, the results of UV protecting ability according to AS/NZS 4399:1996 will be discussed to show that standard clothing materials are not always adequate to prevent effect of UV-R to the human skin; and to suggest the possibilities for its improvement for this purpose enhancing light conversion and scattering. Additionally, the discrepancy in UV protection was investigated in distilled water as well as Adriatic Sea water.

    The provision of continuous, uninterrupted telecommunications service is vital to modern life. In order to provide uninterrupted service to customers, a service continuity program has been in place with AT and T for many years. This program integrates many different protection strategies and plans, each designed to mitigate one of the many threats to service continuity. The fire protection program implemented within AT and T is a part of this service continuity program. In the design of this program, a number of unusual problems had to be addressed due to the service continuity requirements. Typical solutions to fire protection problems (ignition prevention, detection, and suppression) which are embodied in building and fire prevention codes are inadequate to provide service continuity. This presentation outlines the basic arrangement of a telecommunications central office, the specific fire protection problems encountered, the fire protection philosophy developed through the use of a systems approach, and the implementation of the fire protection program. Special emphasis is placed on the strategies employed in lieu of more traditional fire protection schemes and the stimuli for selecting them

It has been also working on R and D of physical protection of nuclear materials and facilities, and enhancing the awareness of the importance of the physical protection among physical protection related people. Japan has now 52 nuclear power reactors, accounting for about one-third of the nations electricity generation. Also nuclear fuel cycle facilities as enrichment plants, radioactive waste disposal facilities and reprocessing plant are either in operation or under construction at Rokkasho-Mura, Aomori prefecture. NMCC is doing several initiatives to strengthen and increase the understanding of the physical protection in Japan by disseminating necessary information to people which are described in the following: 1. Physical protection seminar for the physical protection specialists and management people - It is very important for the physical protection specialists as well as management people who are working at nuclear facilities to be able to get access to the related sophisticated information on the information on the global physical protection issues, physical protection regulations, physical protection systems and equipment etc. This kind of seminar was started in 19xx and is held once a year for two days in Tokyo. The curriculum includes global physical protection issues, physical protection related activities such as terrorism, current R and D, and application of equipment, experiences gained at nuclear facilities. About 70 people participate in the seminar every year. 2.

    2001-01-01

    Full text: INFCIRC 225 Rev. 4 has introduced the Design Basis Threat, DBT, as a key element of the states physical protection system. The DBT is a definition which determines the level of physical protection of nuclear material during use, storage, transport and of nuclear facilities. It the basis for physical protection concepts and for the design of measures the operator or licensee has to provide. By this means it is also a definition of the responsibility for the physical protection which the operator accepts with the license. The new chapter designated to the physical protection against sabotage which has resulted also in the amendment of the title in INFCIRC 225 demonstrates the grown international concern about the potential consequences of sabotage. More than the physical protection against unauthorized removal the physical protection against sabotage has interfaces with the nuclear safety field. The basis of protection against sabotage therefore is much more based on the facility design-the safety design of the facility. Using the DBT the competent authority is in the position to determine the level of protection against sabotage and the remaining risk which has to be accepted. This risk of course depends on the real threat which is not known in advance. The acceptance of the remaining risk depends on both the assessment of the threat, its credibility and the potential consequences. There has been no serious act of sabotage in the past nor an attempt of. Despite of this the Harnun attack of the Japanese underground and some other recent terrorist activities could have given reasons to reconsider what threat might be credible. The German physical protection system has been developed since the increasing terrorist activities in the 1970s. From the beginning the protection against sabotage played an important role in the German system of physical protection. The requirements for the physical protection against unauthorized removal and against sabotage were

    The Security Systems and Technology Center at Sandia National Laboratories has for many years been involved in the development and use of vulnerability assessment and risk analysis tools. In particular, two of these tools, ASSESS and JTS, have been used extensively for Department of Energy facilities. Increasingly, Sandia has been called upon to evaluate critical assets and infrastructures, support DoD force protection activities and assist in the protection of facilities from terrorist attacks using weapons of mass destruction. Sandia is involved in many different activities related to security and force protection and is expanding its capabilities by developing new risk analysis tools to support a variety of users. One tool, in the very early stages of development, is EnSURE, Engineered Surety Using the Risk Equation. EnSURE addresses all of the risk equation and integrates the many components into a single, tool-supported process to help determine the most cost-effective ways to reduce risk. This paper will briefly discuss some of these risk analysis tools within the EnSURE framework

    1998-01-01

    Since its inception in 1996, the purpose of the International Physical Protection Advisory Service (IPPAS) has been to provide advice and assistance to International Atomic Energy Agency (IAEA) Member States on strengthening and enhancing the effectiveness of their state system of physical protection of nuclear materials and facilities. Since the protection of nuclear materials and facilities is a Member State's responsibility, participation within the IPPAS program is voluntary. At the request of a Member State, the IAEA forms a multinational IPPAS team consisting of physical protection specialists. These specialists have broad experience in physical protection system design, implementation, and regulatory oversight. The exact make-up of the team depends upon the needs of the requesting state. IPPAS missions to participating states strive to compare the domestic procedures and practices of the state against international physical protection guidelines (IAEA Information Circular 225) and internationally accepted practice. The missions utilize a top to bottom approach and begin by reviewing the legal and regulatory structure and conclude with reviews of the implementation of the state regulations and international guidelines at individual facilities. IPPAS findings are treated as IAEA Safeguards Confidential Information. To date, IPPAS missions have been concluded in Slovenia, Bulgaria, Romania, Hungary, and Poland

  7. Novel therapy for renal protection.

    2015-08-01

    Acute kidney injury (AKI) is a common and serious complication that significantly increases morbidity, mortality, and cost of care after surgery. In this article, we review recent studies that deal with strategies for renal protection and the prevention of AKI after surgery. A prerequisite for any prophylactic intervention is the identification of patients at risk for AKI or those with acute kidney damage before kidney function deteriorates. In this context, new biomarkers can help to detect cellular injury early. This way, a window for interventions can be opened. Several studies demonstrated the tissue-protective effect of remote ischemic preconditioning in various organs. There is clear evidence that use of balanced crystalloid fluids and the avoidance of hyperchloremic solutions for infusion therapy can reduce the incidence of AKI. Preliminary data show a protective effect if dexmedetomidine is used as a sedative agent following cardiac surgery. The most important intervention with proven efficacy to protect from AKI is aggressive hemodynamic stabilization. Early identification of patients at risk for AKI is crucial to apply any protective intervention. An improved perioperative management is required to prevent AKI. Although pharmacological therapies aiming to protect AKI are under evaluation, hemodynamic optimization and avoidance of nephrotoxic drugs are critical for perioperative patient.

    2005-01-01

    Non-lead aprons using composite materials are often used for radiation protective aprons instead of heavy lead aprons. However, the protective effect of the lighter, non-lead aprons has not been well evaluated, and it is not yet clear how they compare with lead aprons. Therefore, we investigated the protective performance of non-lead aprons theoretically and experimentally by comparing them with lead aprons under clinical conditions. We measured the energy spectra for direct and scattered-rays passing through protective aprons or not, and measured doses with glass dosimeters for validation of theoretical calculations based on the energy spectra. We found that the protective effect of non-lead aprons was higher than that of lead aprons at X-ray of tube voltages of 70-100 kV, which are often used for radiography and fluorography. This demonstrated that the non-lead aprons are more useful in many situations than heavy lead aprons. (author)

    The presentation could only show a very brief overview of the analysis results of a wide study of the existing fire protection situation at Mochovce. As far not already done the next steps will be the selection of the final suppliers of the different measures, the detailed design and the implementation of the measures. As part of the further assistance in fire protection EUCOM will perform compliance checks of the DD and implementation and assist EMO for raising problems. Especially during the implementation of the measures the belonging quality checks have a high priority. Assuming that the implementation of measures will be in accordance with with the study results and the relevant basic design requirements it can be stated that safety level concerning fire protection will be in accordance with international requirement like IAEA 50 SG D2. The next step of our work will be the delta analysis for 2 unit and the relevant basic design as far as there are differences to unit 1. (author)

    Radiation protection is a major challenge in the industrial applications of ionising radiation, both nuclear and non-nuclear, as well as in other areas such as the medical and research domains. The overall objective of this textbook is to participate to the development of European high-quality scheme and good practices for education and training in radiation protection (RP), coming from the new Council Directive 2013/59/Euratom laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation. These ERPTS (European Radiation Protection Training Scheme) reflects the needs of the Radiation Protection Expert (RPE) and the Radiation Protection Officer (RPO), specifically with respect to the Directive 2013/59/Euratom in all sectors where ionising radiation are applied. To reflect the RPE training scheme, six chapters have been developed in this textbook: Radioactivity and nuclear physics; Interaction of ionising radiation with matter; Dosimetry; Biological effects of ionising radiation; Detection and measurement of ionising radiation; Uses of sources of ionising radiation. The result is a homogeneous textbook, dealing with the ERPTS learning outcomes suggested by ENETRAPII project (European Network on Education and Training in Radiological Protection II) from the 7. Framework Programme. A cyber-book is also part of the whole training material to develop the concept of 'learning more' (http://www.rpe-training.eu). The production of this first module 'basics' training material, in the combined form of a textbook plus a cyber-book as learning tools, will contribute to facilitate mutual recognition and enhanced mobility of these professionals across the European Union.

    This document proposes a large and detailed overview of notions and practices regarding radiation protection in relationship with an NPP exploitation framework. It presents the main notions: matter structure, radioactivity, interactions between matter and radiations, types of ionizing radiation, magnitudes and measurement units, exposure modes, main principles of radiation protection, means of protection against internal and external exposures. The second part proposes an overview of the origin of radiological risks in a nuclear power plant. This origin can be found in fission products, activation products, actinides, designed protections, or circuit contaminations. These radiological risks are more precisely identified and described in terms of detection and prevention (internal exposure risk, contamination risk, iodine-related risk, alpha radiation-related risk, access to the reactor building). The next part addresses the medical and radiological follow-up of exposed workers by a special medical control, by an individual exposure control, by a specific control of female personnel, and by attention to exceptional exposures. Measurement means are presented (detection principles, installation continuous control, workspaces control, personnel contamination control, follow-up of individual dose) as well as collective and individual protection means. The management of radiation protection is addressed through a presentation of decision and management structures for radiation protection, and of EDF objectives and ambitions in this domain. The organization of radiation protection during exploitation is described: responsibilities for radiation protection in a nuclear power station, requirements for workers, preparation of interventions in controlled zone, work execution in controlled zone, zone controls and radiological cleanness of installations. The two last chapters address issues and practices of radiation protection in the case of deconstruction or dismantling, and

  16. Occupational radiation protection: Protecting workers against exposure to ionizing radiation. Contributed papers

    International Nuclear Information System (INIS)

    2003-07-01

    Occupational exposure to ionizing radiation can occur in a range of industries, mining and milling; medical institutions, educational and research establishments and nuclear fuel cycle facilities. The term 'occupational exposure' refers to the radiation exposure incurred by a worker, which is attributable to the worker's occupation and committed during a period of work. According to the latest (2000) Report of the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), an estimated 11 million workers are monitored for exposure to ionizing radiation. They incur radiation doses attributable to their occupation, which range from a small fraction of the global average background exposure to natural radiation up to several times that value. It should be noted that the UNSCEAR 2000 Report describes a downward trend in the exposure of several groups of workers, but it also indicates that occupational exposure is affecting an increasingly large group of people worldwide. The International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (BSS), which are co-sponsored by, inter alia, the International Atomic Energy Agency (IAEA), the International Labour Organization (ILO), the OECD Nuclear Energy Agency (NEA) and the World Health Organization (WHO), establish a system of radiation protection which includes radiation dose limits for occupational exposure. Guidance supporting the requirements of the BSS for occupational protection is provided in three interrelated Safety Guides, jointly sponsored by the IAEA and the ILO. These Guides describe, for example, the implications for employers in discharging their main responsibilities (such as setting up appropriate radiation protection programmes) and similarly for workers (such as properly using the radiation monitoring devices provided to them). The IAEA i organized its first International Conference on Occupational Radiation Protection. The

    Based on the high technical status of radiation protection the occupational exposure of radiological personnel is no more of predominant importance. No defined dose limits exist for patients in the frame of therapeutic applications in contrary to the radiological personnel. As a consequence walk-downs radiotherapeutic institutions twice the year have been initiated in order to guarantee a maximum of radiation protection for patient's treatment. An actualization of radiation protection knowledge of the radiological personnel is required.

    Full Text Available The corrosion caused by chemical reaction between metallic structures and surrounding mediums such as soil or water .the CP cathodic protection system is used to protect metallic structure against corrosion. Cathodic protection CP used to minimize corrosion by utilizing an external source of electrical current which forces the entire structure to become a cathode. There are two Types of cathodic protection system Galvanic current Impressed current.the Galvanic current is called a sacrificial anode is connected to the protected structure cathode through a DC power supply. In Galvanic current system a current passes from the sacrificing anode to the protected structure .the sacrificial anode is corroded rather than causing the protected structure corrosion .protected structure requires a constant current to stop the corrosion which determined by area structure metal and the surrounding medium. The rains humidity are decrease soil resistivity and increase the DC current .The corrosion and over protection resulting from increase in the DC current is harmful for the metallic structure. This problem can be solved by conventional cathodic protection system by manual adjustment of DC voltage periodically to obtain a constant current .the manual adjustment of DC voltage depends on experience of the technician and using the accuracy of the measuring equipment. The errors of measuring current depend on error from the technician or error from the measuring equipment. the corrosion of structure may occur when the interval between two successive adjustment is long .An automatically regulated cathodic protection system is used to overcome problems from conventional cathodic protection system .the regulated cathodic protection system adjust the DC voltage of the system automatically when it senses the variations of surrounding medium resistivity so the DC current is constant at the required level.

The standards define internationally harmonized requirements and provide practical guidance for public authorities and services, employers and workers, specialized radiation protection bodies, enterprises and health and safety communities. In the same year, the IAEA, through the technical cooperation programme, launched the Model Project on Upgrading Radiation Protection Infrastructure, a global initiative designed to help Member States establish the infrastructure needed to adhere to the BSS. To address the complexity of this task, the radiation protection team identified key elements, known as Thematic Safety Areas. These are: 1. Legislative Framework and Regulatory Infrastructure, Draft and put into effect radiation protection laws and regulations and establish and empower a national regulatory authority. 2. Occupational Exposure Control Protect the health and safety of each individual who faces the risk of radiation exposure in the workplace through individual and workplace monitoring programmes, including dose assessment, record keeping of doses and quality management. 3. Medical Exposure Control: Develop procedures and activities to control the exposure of patients undergoing diagnosis and/or treatment via diagnostic and interventional radiology, nuclear medicine or radiotherapy through staff training, provision of basic quality control equipment, and the establishment of quality assurance programmes. 4. Public and Environmental Exposure Control: Develop means to protect both the public and the environment including: a) programmes to register, inventory and provide safe storage of unused radioactive sources and material; b) procedures to control and safely

  5. Radiation Protection in Paediatric Radiology

    International Nuclear Information System (INIS)

    2012-01-01

    Over the past decade and a half, special issues have arisen regarding the protection of children undergoing radiological examinations. These issues have come to the consciousness of a gradually widening group of concerned professionals and the public, largely because of the natural instinct to protect children from unnecessary harm. Some tissues in children are more sensitive to radiation and children have a long life expectancy, during which significant pathology can emerge. The instinct to protect children has received further impetus from the level of professional and public concern articulated in the wake of media responses to certain publications in the professional literature. Many institutions have highlighted the need to pay particular attention to the special problems of protecting paediatric patients. The International Commission on Radiological Protection has noted it and the IAEA's General Safety Requirements publication, Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards (BSS), requires it. This need has been endorsed implicitly in the advisory material on paediatric computed tomography scanning issued by bodies such as the US Food and Drug Administration and the National Cancer Institute in the United States of America, as well as by many initiatives taken by other national and regional radiological societies and professional bodies. A major part of patient exposure, in general, and paediatric exposure, in particular, now arises from practices that barely existed two decades ago. For practitioners and regulators, it is evident that this innovation has been driven both by the imaging industry and by an ever increasing array of new applications generated and validated in the clinical environment. Regulation, industrial standardization, safety procedures and advice on best practice lag (inevitably) behind industrial and clinical innovations. This Safety Report is designed to consolidate and provide timely advice on

    1981-10-01

    Generic physical protection logic trees, designed for application to nuclear facilities and materials, are presented together with a method of qualitative evaluation of the trees for design and analysis of physical protection systems. One or more defense zones are defined where adversaries interact with the physical protection system. Logic trees that are needed to describe the possible scenarios within a defense zone are selected. Elements of a postulated or existing physical protection system are tagged to the primary events of the logic tree. The likelihood of adversary success in overcoming these elements is evaluated on a binary, yes/no basis. The effect of these evaluations is propagated through the logic of each tree to determine whether the adversary is likely to accomplish the end event of the tree. The physical protection system must be highly likely to overcome the adversary before he accomplishes his objective. The evaluation must be conducted for all significant states of the site. Deficiencies uncovered become inputs to redesign and further analysis, closing the loop on the design/analysis cycle

  12. Training courses on radiation protection

    International Nuclear Information System (INIS)

    1988-01-01

    Many Member States are developing or already have developed their own national training programmes. The IAEA is actively involved in promoting training in radiological protection, and this report has been prepared to provide the guidance that may be required in this development. The original version of the report on this subject was published in 1964 as Technical Reports Series No. 31 entitled ''Training in Radiological Protection: Curricula and Programming''. In 1975 a second version was published entitled ''Training in Radiological Protection for Nuclear Programmes'' as Technical Reports Series No. 166. This publication is intended mainly for use by persons who are responsible for organizing training programmes in radiation protection. It also reflects the policy of the Agency to have continuing standardized training in radiation protection. In addition to a small change in the title of the report, some concepts and ideas which are no longer applicable have been omitted and new information included. An important part of this report is the list of courses now offered in many Member States

  13. Protective Skins for Composite Airliners

    Johnson, Vicki S.; Boone, Richard L.; Jones, Shannon; Pendse, Vandana; Hayward, Greg

    2014-01-01

    Traditional composite aircraft structures are designed for load bearing and then overdesigned for impact damage and hot humid environments. Seeking revolutionary improvement in the performance and weight of composite structures, Cessna Aircraft Company, with sponsorship from the NASA Fundamental Aeronautics Program/Subsonic Fixed Wing Project, has developed and tested a protective skin concept which would allow the primary composite structure to carry only load and would meet the impact, hot and humid, and other requirements through protective skins. A key requirement for the protective skins is to make any impact damage requiring repair visible. Testing from the first generation of skins helped identify the most promising materials which were used in a second generation of test articles. This report summarizes lessons learned from the first generation of protective skins, the design and construction of the second-generation test articles, test results from the second generation for impact, electromagnetic effects, aesthetics and smoothing, thermal, and acoustic (for the first time), and an assessment of the feasibility of the protective skin concept.

  16. Basic standards for radiation protection

    International Nuclear Information System (INIS)

    Webb, G.A.M.

    1982-01-01

    The basic standards for radiation protection have been based, for many years, on the recommendations of the International Commission of Radiological Protection. The three basic standards recommended by the Commission may be summarized as ''justification, optimization of protection and adherence to dose limitations. The applications of these basic principles to different aspects of protection are briefly summarized and the particular ways in which they have been applied to waste described in more detail. The application of dose limits, both in the control of occupational exposure and in regulating routine discharges of radioactive effluents is straight forward in principle although the measurement and calculational requirements may be substantial. Secondary standards such as derived limits may be extremely useful and the principles underlying their derivation will be described. Optimization of protection is inherently a more difficult concept to apply in protection and the various techniques used will be outlined by with particular emphasis on the use of cost benefit analysis are recommended by the ICRP. A review will be given of the problems involved in extending these basic concepts of the ICRP to probabilistic analyses such as those required for assessing the consequences of accidents or disruptive events in long term repositories. The particular difficulties posed by the very long timescales involved in the assessment of waste management practices will be discussed in some detail. (orig./RW)

    A Technical Committee on Physical Protection of Nuclear Material met in April-May 1989 to advise on the need to update the recommendations contained in document INFCIRC/225/Rev.1 and on any changes considered to be necessary. The Technical Committee indicated a number of such changes, reflecting mainly: the international consensus established in respect of the Convention on the Physical Protection of Nuclear Material; the experience gained since 1977; and a wish to give equal treatment to protection against the theft of nuclear material and protection against the sabotage of nuclear facilities. The recommendations presented in this IAEA document reflect a broad consensus among Member States on the requirements which should be met by systems for the physical protection of nuclear materials and facilities. 1 tab

  9. Critical Issues in Radiation Protection Knowledge Management for Preserving Radiation Protection Research and Development Capabilities.

    Science.gov (United States)

    Dewji, Shaheen Azim

    2017-02-01

    As a hub of domestic radiation protection capabilities, Oak Ridge National Laboratory's Center for Radiation Protection Knowledge has a mandate to develop and actuate a formal knowledge management (KM) effort. This KM approach exceeds recruitment and training efforts but focuses on formalized strategies for knowledge transfer from outgoing subject matter experts in radiation protection to incoming generations. It is envisioned that such an effort will provide one avenue for preserving domestic capabilities to support stakeholder needs in the federal government and the nuclear industry while continuing to lead and innovate in research and development on a global scale. However, in the absence of broader coordination within the United States, preservation of radiation protection knowledge continues to be in jeopardy in the absence of a dedicated KM effort.

  17. New trends in radiation protection

    International Nuclear Information System (INIS)

    Lindell, B.

    1977-10-01

    The introduction of new concepts such as the effective dose equivalent, the collective dose and the dose commitment, and the application of the basic principles of justification, optimization and individual dose limitation has had a major impact on the planning and implementation of radiation protection during the last few years. The basic principles are summarized in ICRP Publication 26. It is a chalenge to research in radiobiology, genetics and health physics to explore the scientific foundation of the current principles of radiation protection. The most interesting trend to-day, however, is the observation that the principles applied in radiation protection have now been generally recognized and accepted to the extent that they become utilized in the protection of man against non-radioactive carcinogenic substances and environmental pollutants.

    This contribution investigates the possible danger and the legal basis of physical protection and explains the current, integrated system provided for, as well as the underlying possible scenarios of an assault: (1) by a violent crowd of aggressors outside the installation, (2) by a small group of aggressors outside the installation, (3) by a person allowed to enter (internal assault). The physical protection system supplements the internal safety measures to enhance protection against hypothetical and possible acts of terrorism or other criminal assault. The system covers external and internal controlled areas, access monitoring, physical protection control room and service, security checks of the personnel, and activities to disclose sabotage. Some reflections on the problem field between security controls and the constitutional state conclude this contribution. (orig./HSCH) [de

    International Nuclear Information System (INIS)

    Boehler, M.C.

    1996-01-01

    In order to encourage a high degree of radiation protection of workers and members of public, the relevant authorities and operators in the nuclear industry should urge those responsible for radiation protection to do more than is required bu the pure and simple application of the regulations related to dose limitation compliance with the technical standards and specifications a necessary but not sufficient condition for quality in radiation protection. Reaching this quality objective is not a matter of forcing improvements bu a regulatory policy of reducing dose limits, but of promoting a real radiation protection culture based on an approach of optimizing the radiation protection formalized at the lightest level of the company structure, as well as on the professionalism individual responsibility, motivation and the freely consented to and understood participation of those involved in implementing this policy. The spread of a radiation protection culture encourages the deliberate adoption in everyday practice of behaviour likely to reduce exposure to ionizing radiation, as law as reasonably achievable, and to give life to the 'spirit' of the regulations in the best conditions. This article intends to show that the need to diffuse a radiation protection culture, particularly based on the principle of optimization, is inspired both by the philosophy behind the system recommended by the behavioural and incentive approach implied by the optimization principle. Special attention will be given to the fundamentals likely to contribute in a definition of radiation protection culture. (author)

  17. Pressure Shell Approach to Integrated Environmental Protection

    2011-01-01

    The next generation of exploration mission human systems will require environmental protection such as radiation protection that is effective and efficient. In order to continue human exploration, habitat systems will require special shells to protect astronauts from hostile environments. The Pressure Shell Approach to integrated environmental (radiation) protection is a multi-layer shell that can be used for multifunctional environmental protection. Self-healing, self-repairing nano technologies and sensors are incorporated into the shell. This shell consists of multiple layers that can be tailored for specific environmental protection needs. Mainly, this innovation focuses on protecting crew from exposure to micrometeorites, thermal, solar flares, and galactic cosmic ray (GCR) radiation. The Pressure Shell Approach consists of a micrometeoroid and secondary ejecta protection layer; a thin, composite shell placed in between two layers that is non-structural; an open cavity layer that can be filled with water, regolith, or polyethylene foam; a thicker composite shell that is a structural load bearing that is placed between two layers; and a bladder coating on the interior composite shell. This multi-layer shell creates an effective radiation protection system. Most of its layers can be designed with the materials necessary for specific environments. In situ materials such as water or regolith can be added to the shell design for supplemental radiation protection.

  18. Enhancing radiation protection

    International Nuclear Information System (INIS)

    2006-01-01

    When a new radiotherapy center in Gezira, Sudan, delivers its first therapeutic dose to a cancer patient, two things happen: A young man begins to regain his health and looks forward to being better able to support his family and contribute to his community; and a developing nation realizes an important step toward deriving the social and economic benefits of nuclear science. The strategic application of nuclear technology in particular fields- human health, industry, food and agriculture, energy, water resources and environmental protection - has enormous potential to help shape the future of developing countries. But past radiological incidents, several of which involved high levels of exposure or death (Bolivia, Brazil, Cost Rica, Georgia, Ghana, Morocco, Panama and Thailand), underscore the inherent and very serious risks. For this reason, the IAEA's Departments of Technical Cooperation and Nuclear Safety and Security partner closely, particularly in the area of radiation protection. They strive to consider every minute detail in the equation that brings together radiation sources, modern technologies, people and the environment. Launched in 1996, the Model Project on Upgrading Radiation Protection Infrastructure (the Model Project) aimed to help Member States: achieve capacities that underpin the safe and secure application of nuclear technologies; establish a legislative framework and regulatory infrastructure; develop exposure control mechanisms to protect workers, medical patients, the public and the environment; and achieve preparedness and planned response to radiological emergencies. In fact, the hospital scenario above typically marks several years of intense collaboration amongst scientists, legislators, regulators, politicians and administrators from both Member States and the IAEA, orchestrated and aided by regional managers and technical experts from the IAEA. As radiation protection team members can attest, every application of nuclear technology

    Three main pillars underpin the IAEA's mission: Safety and Security - The IAEA helps countries to upgrade their infrastructure for nuclear and radiation safety and security, and to prepare for and respond to emergencies. Work is keyed to international conventions, the development of international standards and the application of these standards. The aim is to protect people and the environment from the harmful effects of exposure to ionizing radiation. Science and Technology - The IAEA is the world's focal point for mobilizing peaceful applications of nuclear science and technology for critical needs in developing countries. The work contributes to alleviating poverty, combating disease and pollution of the environment and to other goals of sustainable development. Safeguards and Verification - The IAEA is the nuclear inspectorate, with more than four decades of verification experience. Inspectors work to verify that nuclear material and activities are not diverted towards military purposes. Quantities and Units: Dose equivalent is the product of absorbed dose of radiation and quality factor (Q). For absorbed dose in rads, dose equivalent is in rems. If absorbed dose is in gray, the dose equivalent is in sievert. Quality factor is defined without reference to any particular biological end point. Quality factors are recommended by committees such as the International Commission on Radiological Protection (ICRP) or the National Council on Radiation Protection and Measurements (NCRP), based on experimental RBE values but with some judgment exercised. Effective Dose Equivalent: It is the sum of the weighted dose equivalents for all irradiated tissues, in which the weighting factors represent the different risks of each tissue to mortality from cancer and hereditary effects. Committed dose equivalent: It is the integral over 50 years of dose equivalent following the intake of a radionuclide. Collective effective dose equivalent: It is a quantity for a population and is

  20. State duties of protection and fundamental rights

    Full Text Available Duties of protection are duties of the state to protect certain legal interests of its citizens. They cover the interests of life, health, freedom and property and also protect some other interests and certain constitutionally recognised institutions. State duties of protection must be considered in connection with fundamental rights. The foundations of modern constitutionalism and attendant procedures are essential to develop guidelines for a constructive critique of the jurisprudence of the Constitutional Court. This is done with reference to the recent history of France, Germany and England. The historical excursus reveals that a single theory underlies the variety of constitutional states. The development of the constitutional state gave rise to the significance of the preservation of freedom through the maintenance of law and the separation of powers. This has given rise to various legal devices, based also in part on experience with moderate rule and earlier theories of the imperium limitatum.A textual analysis of the German Basic Law is undertaken to determine whether and how the duties of protection are expressly created. Furthermore, the duties that have been discovered in the Basic Law by the Federal Constitutional Court are considered. These duties include the protection of human life and health, personal freedom, the right to autonomous development of one's personality, freedom of science, research and teaching, marriage and the family, children, mothers, professional freedom, property and the protection of German nationals against foreign states. Finally the justification of such duties and the constitutional control of the manner of protection are considered.In a final section a critique of relevant constitutional jurisprudence is undertaken. It is argued that claims to protection cannot be directly binding law. They presuppose legislation. If statutory protection is connected with infringements of third-party fundamental rights

    A trend to design new motors closer to their design limits and the high cost of plant shutdown has increased the need for better protection of smaller three phase motors. A single chip microcomputer relay can be applied to replace thermal overloads which are of limited effectiveness on low and medium voltage machines with comprehensive, economical motor protection. The requirement for different protection features and how they are achieved is presented. All the protection features discussed are commercially available in a compact unit that uses a single chip microcomputer.

    2005-07-01

    Our objective was to assess the prevalence of protective equipment use and the motivation for using protective equipment among a sample of US female rugby players. We surveyed a convenience sample of 234 current US female rugby players from 14 teams participating in a US women's rugby tournament, obtaining self-reported demographic, rugby exposure, and protective equipment use information. Mouthguards were the most commonly used piece of protective equipment: 90.8% of players reported having always worn a mouthguard while playing or practicing rugby within their most recent 3 months of play. Fewer than 15% of players reported having always worn other types of protective equipment. Equipment use varied by playing position. Whereas over 80% of players in all other positions always wore a mouthguard, 66.7% of scrum halves reported always wearing one. Both backs and forwards reported wearing shoulder pads, but only forwards reported always wearing padded headgear. Mouthguards, padded headgear, and shoulder pads were worn "to prevent injury," whereas ankle braces, neoprene sleeves, and athletic tape on joints were worn "to protect a current/recent injury." This is the first study of female rugby players to assess the prevalence of protective equipment use by playing position and the motivation for using protective equipment. With the exception of mouthguards, US female rugby players infrequently use protective equipment. Protective equipment use varies by playing position. Some types of protective equipment appear to be used as primary prevention mechanisms, whereas others are used as secondary or tertiary prevention mechanisms.

  9. [Cerebral protection].

    Science.gov (United States)

    Cattaneo, A D

    1993-09-01

    Cerebral protection means prevention of cerebral neuronal damage. Severe brain damage extinguishes the very "human" functions such as speech, consciousness, intellectual capacity, and emotional integrity. Many pathologic conditions may inflict injuries to the brain, therefore the protection and salvage of cerebral neuronal function must be the top priorities in the care of critically ill patients. Brain tissue has unusually high energy requirements, its stores of energy metabolites are small and, as a result, the brain is totally dependent on a continuous supply of substrates and oxygen, via the circulation. In complete global ischemia (cardiac arrest) reperfusion is characterized by an immediate reactive hyperemia followed within 20-30 min by a delayed hypoperfusion state. It has been postulated that the latter contributes to the ultimate neurologic outcome. In focal ischemia (stroke) the primary focus of necrosis is encircled by an area (ischemic penumbra) that is underperfused and contains neurotoxic substances such as free radicals, prostaglandins, calcium, and excitatory neurotransmitters. The variety of therapeutic effort that have addressed the question of protecting the brain reflects their limited success. 1) Barbiturates. After an initial enthusiastic endorsement by many clinicians and years of vigorous controversy, it can now be unequivocally stated that there is no place for barbiturate therapy following resuscitation from cardiac arrest. One presumed explanation for this negative statement is that cerebral metabolic suppression by barbiturates (and other anesthetics) is impossible in the absence of an active EEG. Conversely, in the event of incomplete ischemia EEG activity in usually present (albeit altered) and metabolic suppression and hence possibly protection can be induced with barbiturates. Indeed, most of the animal studies led to a number of recommendations for barbiturate therapy in man for incomplete ischemia. 2) Isoflurane. From a cerebral

    We aimed to evaluate the performance of medical personnel in using the IB1 topical protective lotion on their hands and wrists together with standard disposable medical gloves, compared to standard-issued medical chemical protective gloves. This randomized cross-over study included 144 medical personnel. Primary endpoints were time-to-completion of autoinjection; success rate, number of attempts, and time-to-achieve successful endotracheal intubation; time-to-achieve satisfactory tube fixation; time-to-draw and inject the content of an ampoule; and the total time-to-perform all medical procedures. Secondary endpoints included the subjective assessment of convenience to perform these four procedures with each protective measure. Mean time was significantly shorter using IB1 compared to chemical protective gloves for tube fixation, ampoule drawing, and the total time-to-perform all procedures (58.6±22.7 seconds vs. 71.7±29.7; 31.5±21.8 vs. 38.2±19.4; 137.4±56.1 vs. 162.5±63.6, respectively; Pgloves (Pgloves significantly shorten the time-to-perform medical procedures requiring fine motor dexterities and is subjectively more convenient than chemical protective gloves. IB1 should be considered as an appropriate alternative for medical teams in a chemical event. Copyright © 2016 Elsevier Inc. All rights reserved.

  11. The future policy for radiological protection

    International Nuclear Information System (INIS)

    2004-01-01

    At the end of the 1990's, the International Commission on Radiological Protection (ICRP) launched a process for establishing new recommendations, which are expected to serve as guidelines for national systems of radiological protection. Currently the ICRP's proposed recommendations are being subjected to extensive stakeholder comment and modifications. The NEA Committee on Radiation Protection and Public Health (CRPPH) has been actively involved in this process. Part of the Committee's work has been to undertake collaborative efforts with the ICRP through, for example, the organisation of broad stakeholder fora. The first of these, held in Taormina, Italy in 2002, focused on the development of a policy basis for the radiological protection of the environment. The second forum, held in Lanzarote, Spain in April 2003, addressed the latest concepts and approaches in the ICRP proposed recommendations for a system of radiological protection. During this meeting, the ICRP listened to the views of various stakeholder groups, including radiological protection regulators, environmental protection ministries, the nuclear power industry and NGOs. As a result, the ICRP modified its proposals to better reflect stakeholder needs and wishes. This report presents the outcomes of the discussions, examining what the ICRP proposed and how its proposals have been affected and modified as a result of stakeholder input. (author)

  16. Movable scour protection. Model test report

    Energy Technology Data Exchange (ETDEWEB)

    Lorenz, R.

    2002-07-01

    This report presents the results of a series of model tests with scour protection of marine structures. The objective of the model tests is to investigate the integrity of the scour protection during a general lowering of the surrounding seabed, for instance in connection with movement of a sand bank or with general subsidence. The scour protection in the tests is made out of stone material. Two different fractions have been used: 4 mm and 40 mm. Tests with current, with waves and with combined current and waves were carried out. The scour protection material was placed after an initial scour hole has evolved in the seabed around the structure. This design philosophy has been selected because the situation often is that the scour hole starts to generate immediately after the structure has been placed. It is therefore difficult to establish a scour protection at the undisturbed seabed if the scour material is placed after the main structure. Further, placing the scour material in the scour hole increases the stability of the material. Two types of structure have been used for the test, a Monopile and a Tripod foundation. Test with protection mats around the Monopile model was also carried out. The following main conclusions have emerged form the model tests with flat bed (i.e. no general seabed lowering): 1. The maximum scour depth found in steady current on sand bed was 1.6 times the cylinder diameter, 2. The minimum horizontal extension of the scour hole (upstream direction) was 2.8 times the cylinder diameter, corresponding to a slope of 30 degrees, 3. Concrete protection mats do not meet the criteria for a strongly erodible seabed. In the present test virtually no reduction in the scour depth was obtained. The main problem is the interface to the cylinder. If there is a void between the mats and the cylinder, scour will develop. Even with the protection mats that are tightly connected to the cylinder, scour is expected to develop as long as the mats allow for

    International Nuclear Information System (INIS)

    Ban, Minoru; Umeda, Kenji; Kubo, Noboru; Ito, Tomohiro.

    1996-01-01

    The present invention provides an improved protective guide structure for control rods, which does not cause swirling of coolants and resonance even though a slit is formed on a protective tube which surrounds a control rod element in a PWR type reactor. Namely, a reactor control rod is constituted with elongated control elements collectively bundled in the form of a cluster. The protective guide structure protectively guides the collected constituent at the upper portion of a reactor container. The protective structure comprises a plurality of protective tubes each having a C-shaped cross section disposed in parallel for receiving control rod elements individually in which the corners of the opening of the cross section of the protective tube are chamfered to an appropriate configuration. With such a constitution, even if coolant flows in a circumferential direction along the protective tubes surrounding the control rod elements, no shearing stream is caused to the coolants flow since the corners of the cross sectional opening (slit) of the tube are chamfered. Accordingly, occurrence of swirlings can be suppressed. (I.S.)

  20. Issues around radiological protection of the environment and its integration with protection of humans: promoting debate on the way forward

    International Nuclear Information System (INIS)

    Brownless, G P

    2007-01-01

    This paper explores issues to consider around integrating direct, explicit protection of the environment into the current system of radiological protection, which is focused on the protection of humans. Many issues around environmental radiological protection have been discussed, and ready-to-use toolboxes have been constructed for assessing harm to non-human biota, but it is not clear how (or even if) these should be fitted into the current system of protection. Starting from the position that the current approach to protecting the environment (namely that it follows from adequately protecting humans) is generally effective, this paper considers how explicit radiological protection of the environment can be integrated with the current system, through developing a 'worked example' of how this could be done and highlighting issues peculiar to protection of the environment. The aim of the paper is to promote debate on this topic, with the ultimate aim of ensuring that any changes to the system are consensual and robust

    Harbach, F.; Nicoll, A.

    1987-01-01

    The basic material of the above-mentioned layer consists of pure aluminium oxide or essentially aluminium oxide. To improve this protective layer metal oxides from the groups IIA, IIIA, IIIB, VB, VIB, VIIB or VIII of the periodic system are added to its basic material before the said protective coating is applied. In this way a corundum structure is formed in the case of aluminium oxide. Gallium oxide, vanadium oxide, chromium oxide or iron oxide are particularly suited for the correlation of such a corundum structure. The formation of the corundum structure increases the resistance of the protective coating to the corrosive effects of vanadium pentoxide and sodium sulfate. By the addition of a specific quantity of magnesium oxide it is possible not only to stimulate the formation of corundum but also to reduce the increase in grain size in the case of the aluminium oxide. The other metallic oxides are especially favorable to the formation of the corundum structure, so that preferably magnesium oxide is to be added to these metallic oxides in order to reduce the increase in grain size.

    International Nuclear Information System (INIS)

    1990-01-01

    This document aims to trace the evolution of the CEC radiation protection programme over its 30 years of existence. During this time, research carried out in the framework of the Community programme has made major contributions to the scientific understanding of the action of ionizing radiation and the protection of man and his environment. This information was crucial for developing better radiation protection management for existing and new technologies and for providing the scientific basis for the regulatory activities of the Commission. One important feature of the programme was the success of bringing together scientists from different Member States to cooperate in the various fields of radiation protection and to integrate different areas of radiation protection research into a coherent approach. The structures thus developed within the programme have enabled research in radiation protection to be conducted in a cost-effective manner on behalf of the Member States. This document aims also to give a synopsis of the most important results of the 1985-89 radiation protection programme. This period was characterized by two challenges, the integration of two Member States into Community research and the impact of the Chernobyl accident. The programme has, in spite of reduced funding, continued to provide a high degree of expertise for the Community in the context of the needs in radiation protection. This has been explicity acknowledged in the evaluation of the 1980-89 programmes carried out by an independent panel

    As a hub of domestic radiation protection capabilities, Oak Ridge National Laboratory’s Center for Radiation Protection Knowledge has a mandate to develop and actuate a formal knowledge management (KM) effort. This KM approach exceeds recruitment and training efforts but focuses on formalized strategies for knowledge transfer from outgoing subject matter experts in radiation protection to incoming generations. It is envisioned that such an effort will provide one avenue for preserving domestic capabilities to support stakeholder needs in the federal government and the nuclear industry while continuing to lead and innovate in research and development on a global scale. Furthermore, in the absence of broader coordination within the United States, preservation of radiation protection knowledge continues to be in jeopardy in the absence of a dedicated KM effort.

    The environmental protection is part of the radiation protection but without defined regulations concerning the protection of non-human species and the ecological systems. In 2008 the SSK (Strahlenschutzkommission) was asked to elaborate measures for environmental radiation protection. Part of the recommendation was the application of sustainability concepts on radioactive materials.

    Compounds capable of protecting cells against hyperthermia may provide new insights into potential mechanisms of thermotolerance and cellular heat death. The authors characterized heat protection by alanine and related compounds as a function of concentration, temperature and preincubation time. Alanine was added either to complete medium or to HBSS before hyperthermia. Maximal heat protection required 3 hr, 37 0 ; longer preincubation intervals resulted in lower levels of protection. Addition of alanine to medium after hyperthermia had no protective effect. Protection was concentration dependent with a 20- or 200-fold increase in cell survival after 40 min, 45 0 C at 60 mM in medium or in HBSS, respectively. Higher alanine concentrations up to 120mM did not significantly increase heat protection. A 45 0 -heat survival curve showed that 100mM alanine increased the D/sub q/ by approx. 12 min with little change in the D/sub o/. Hyperthermia of 1 hr at temperatures between 42 0 and 45 0 indicated that 100mM alanine shifted the isotoxic temperature by 0.5 Celsius degrees. Polymers of either L or D,L alanine and related compounds, like pyruvate, also protected cells against heat killing. These results indicate that heat protection by alanine shows characteristics that are not shared by polyhydroxy compounds

    1993-01-01

    In the interest of environmental protection, improvement of working conditions, and reduced fire hazard in production operations, water-based protective lubricants are now available in a wide assortment, and the production volume has increased greatly. The term water-dilutable inhibited protective lubricants (WDIPL) means water-soluble, water-emulsifiable, or water-dispersible products with the dual function of reducing friction and wear and protecting metal surfaces against corrosion for specified periods of time. According to the standard Unified System of Protection Against Corrosion and Aging (COST 9.103-78), WDIPLs are classed as products for the temporary corrosion protection of metals and end-items. In the general class of WDIPLs one can identify water-dilutable combination corrosion inhibitors, film-forming inhibited petroleum compositions (FIPC-d), detergent-preservative fluids, operational-preservative lubricating-cooling process compounds (ICPC), and, finally, universal multifunctional products. Combined corrosion inhibitors may consist of water-soluble organic and inorganic compounds; water/oil and oil-soluble surfactants - corrosion inhibitors of the chemisorption type or donor and/or acceptor types; shielding inhibitors of the adsorption type; and fast-acting water-displacing components. 23 refs

  9. [Artificial intelligence] AI for protection systems

    1997-12-31

    The reliable operation of large power systems with small stability margins is highly dependent on control systems and protection devices. Progress in the field of microprocessor systems and demanding requirements in respect of the performance of protective relays are the reasons for digital device applications to power system protection. The superiority of numeric protection over its analogue alternatives is attributed to such factors as accurate extraction of the fundamental voltage and current components through filtering, functional benefits resulting from multi-processor design and extensive self-monitoring, etc. However, all these reasons have not led to a major impact on speed, sensitivity and selectivity of primary protective relays, and the gains are only marginal; this is so because conventional digital relays still rely on deterministic signal models and a heuristic approach for decision making, so that only a fraction of the information contained within voltage and current signals as well as knowledge about the plant to be protected is used. The performance of digital relays may be substantially improved if the decision making is based on elements of artificial intelligence (AI). (Author)

  10. Regulatory requirements for radiation protection

    Regulatory requirements for radiation protection have evolved and matured over several decades. Due to the wide adoption of recommendations of the International Commission on Radiation Protection (ICRP), there exists international agreement on the principles to be followed for radiation protection. This foundation will be increasingly important due to the growing need for international agreements and standards for radiation protection and radioactive materials management. During the infancy of the commercial nuclear industry, primary reliance was placed on the protection of the individual, both in the work force and as a member of the public. With the growth of nuclear power in the 1960's and 1970's, environmental impact assessments and expert reviews of bio-effects data have focused attention on statistical risks to large population groups and the use of the collective dose commitment concept to estimate potential effects. The potential release of long-lived radionuclides from the nuclear fuel cycle requires further consideration of radionuclide accumulation in the biosphere and calls for controls conceived and implemented at the international level. The initial development efforts for addressing these concerns already have been instituted by the ICRP and the IAEA. However, formal international agreements and a unified set of international standards may be required to implement the recommendations of these groups. Further international efforts in the field of radiation protection are also called for in developing waste management practices and radioactive effluent control technology, in site selection for fuel reprocessing plants and waste dispersal facilities, and for ensuring safe transport of high-level wastes in various forms. Since the regulation of very low dose rates and doses will be involved, it will be useful to reexamine dose-effect relationships and societal goals for health protection.

    1975-01-01

    Full text: An Advisory Group met to consider the up-dating and extension of the Recommendations for the Physical Protection of Nuclear Material, produced in 1972. Twenty-seven experts from 11 countries and EURATOM were present. Growing concern has been expressed in many countries that nuclear material may one day be used for acts of sabotage or terrorism. Serious attention is therefore being given to the need for States to develop national systems for the physical protection of nuclear materials during use, storage and transport throughout the nuclear fuel cycle which should minimize risks of sabotage or theft. The revised Recommendations formulated by the Advisory Group include new definitions of the objectives of national systems of physical protection and proposals for minimizing possibilities of unauthorized removal and sabotage to nuclear facilities. The Recommendations also describe administrative or organizational steps to be taken for this purpose and the essential technical requirements of physical protection for various types and locations of nuclear material, e.g., the setting up of protected areas, the use of physical barriers and alarms, the need for security survey, and the need of advance arrangements between the States concerned in case of international transportation, among others.

    1975-01-01

    At the request of the Ministry for Research and Technology, the 'Arbeitsgemeinschaft der Grossforschungseinrichtungen' (AGF) presented in 1972 an information brochure called 'Activities in the field of environmental research and environmental protection', closely associated with the environmental programme of the Federal government (1971). The information brochure reports on those activities of the working group's members which are closely, or less closely, connected with questions concerning environmental research and protection, however, investments for the protection of the individual facilities in internal operation are excluded. The AGF programme 'Environmental research and environmental protection' comprises contributions, brought up to date, of member companies. From the 'AGF programme survey 1974' it contains 'Environmental research' as well as aspects of nuclear development with environmental relevance. Technologies not harmful to the environment developed by the research facilities are only mentioned very briefly. (orig.) [de

    It can be defined radiation protection culture as the set of technical and social standards applied to the management of the operation of a nuclear facility concerning the reduction of the exposure to radiation of workers and members of the public, together with the behaviour and attitudes of the individuals from the organization towards that objective. Because the basic principles of radiation protection are self-evident and are totally justified, and the thesis drawn from the article is that no effective radiation protection culture yet exists within the organization, it must be concluded that what is wrong from the system are the attitudes and behavior of the individuals. In this article some factors and elements needed to motivate all persons within the organization towards the creation of a radiation protection culture are delineated and presented. (Author)

    Eye injuries sustained during sport comprise up to 20 per cent of all injuries to the eye serious enough for medical attention to be sought. The prevalence of eye injuries in sport is not easily assessed due to lack of authoritative participation rates, so most studies report total numbers in a time period. The evidence on the proportion of all ocular injuries that are from sport is reviewed. The relative frequencies in different sports are compared in a qualitative manner and the sports with greater numbers of ocular injuries are detailed. In common with occupational injuries to the eye, most sports eye injuries are considered preventable. The hierarchy of action for occupational risk is detailed and adapted to use in a sports scenario. All the available international, regional and national standards on sports eye protection are detailed and their provisions compared. The major function of the standards is to provide adequate protection against the hazard of the sport concerned. These are detailed and compared as a function of energy transfer. Eye protection must not introduce additional or secondary hazards (for instance, fracturing into sharp fragments on impact) and not introduce features that would deter the wearing of eye protection (for instance, restricting field of view to impede playing the sport). The provisions of the standards intended to limit secondary hazards are detailed and compared. The need for future work in standards writing and the activities of the International Standardization Organization in sports eye protection are detailed. © 2016 Optometry Australia.

    The structural complexity of coral reefs is important for their function as shelter and feeding habitats for coral reef fishes, but physical disturbance by human activities often reduce complexity of the reefs by selectively destroying fragile and more complex coral species. The damselfish Springer......'s demoiselle Chrysiptera springeri primarily utilize complex coral heads for shelter and are hence vulnerable to human disturbance. In order to evaluate the potential effect of habitat degradation on juvenile fish growth, coral reef cover, fish age at settling and otolith growth, juvenile Springer's demoiselle...... was investigated on a protected and non-protected coral reef in Darvel Bay, Borneo. The protected reef had higher coverage of complex branching corals and exhibited a more complex 3-dimensional structure than the non-protected reef.

    Background In developing countries the prevalence of duodenal ulceration is related to the staple diet and not to the prevalence of Helicobacter pylori. Experiments using animal peptic ulcer models show that the lipid fraction in foods from the staple diets of low prevalence areas gives protection against ulceration, including ulceration due to non-steroidal anti-inflammatory drugs (NSAIDs), and also promotes healing of ulceration. The lipid from the pulse Dolichos biflorus (Horse gram) was highly active and used for further investigations. Further experiments showed the phospholipids, sterol esters and sterols present in Horse gram lipid were gastroprotective. Dietary phospholipids are known to be protective, but the nature of protective sterols in staple diets is not known. The present research investigates the nature of the protective phytosterols. Methods Sterol fractions were extracted from the lipid in Dolichos biflorus and tested for gastroprotection using the rat ethanol model. The fractions showing protective activity were isolated and identification of the components was investigated by Gas Chromatography-Mass Spectrometry (GC-MS). Results The protective phytosterol fraction was shown to consist of stigmasterol, β-sitosterol and a third as yet unidentified sterol, isomeric with β-sitosterol. Conclusions Dietary changes, affecting the intake of protective phospholipids and phytosterols, may reduce the prevalence of duodenal ulceration in areas of high prevalence and may reduce the incidence of recurrent duodenal ulceration after healing and elimination of Helicobacter pylori infection. A combination of phospholipids and phytosterols, such as found in the lipid fraction of ulceroprotecive foods, may be of value in giving protection against the ulcerogenic effect of NSAIDs.

    The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

    1980-01-01

    Computer simulations and laboratory tests were used to evaluate the hazard posed by lightning flashes to ground on the Solar Power Satellite rectenna and to make recommendations on a lightning protection system for the rectenna. The distribution of lightning over the lower 48 of the continental United States was determined, as were the interactions of lightning with the rectenna and the modes in which those interactions could damage the rectenna. Lightning protection was both required and feasible. Several systems of lightning protection were considered and evaluated. These included two systems that employed lightning rods of different lengths and placed on top of the rectenna's billboards and a third, distribution companies; it consists of short lightning rods all along the length of each billboard that are connected by a horizontal wire above the billboard. The distributed lightning protection system afforded greater protection than the other systems considered and was easier to integrate into the rectenna's structural design.

    Full text: This work summarises the main ideas and achievements of the Science and Values in Radiological Protection Workshop that was held on 15-17 January 2008 in Helsinki, Finland. In the view of developing of new radiological applications and emerging scientific phenomena it has been recognized a need to develop a shared understanding of emerging challenges for radiological protection among scientific and regulatory communities, public and other concerned stake holders. In response to this the Committee of Radiation Protection and Public Health of the OECD Nuclear Energy Agency and Radiation and Nuclear Safety Authority of Finland tried to initiate a process of longer-term reflection on scientific and societal issues that might challenge radiological protection in the coming years. Among general issues like radiological policy issues, improvement of understanding between research and policy communities, sharing views on emerging scientific issues, there were addressed several scientific issues, like non-targeted effects, individual sensitivity; and circulatory diseases. The main focus of these discussions was to elaborate potential 'what if' scenarios and propose feasible solutions at various levels. These discussions addressed effects that are not direct and evident consequence of the initial lesions produced at the cellular and DNA level like bystander responses, genomic instability, gene induction, adaptive responses and low dose. Particular interest was paid to an extrapolation of risk estimates to low doses and role of Linear Non-Threshold theory in setting regulatory principles. Individual radio-sensitivity and identification of genes that are suspected of having an influence on it were also discussed in one of the Breakout Sessions. Another Breakout Session addressed circulatory diseases. There is emerging evidence in the A-bomb survivors and in other exposed groups that ionising radiation also causes other diseases than cancer, such as circulatory

    One of the most pressing ecological problems is the man-made greenhouse effect. In relevant scientific and environmental-policy discussions the questions of how to achieve the ecological target and, in particular, the costs of climate protection are moving into the centre of interest. The global dimension of the climate problem calls for the greatest possible number of states to join a climate protection convention. Therefore it is of central importance to hammer out a climate convention that will prompt developed and less developed states to join it and fulfill their commitments. The complex negotiations held in June 1992 in Rio de Janeiro during the United Nations Conference on Environment and Development (UNCED) have shown that, to do so, it is not only necessary to make use of basic scientific data but to take, moreover, economic and development-political aspects into account.- The meanwhile ratified climate protection convention recommends making use of compensations, or ''joint implementations'', in order to foster climate protection. The book examines the theoretical meaning and practical applicability of this environment-political tool and makes concrete proposals for its practical implementation. But, as the author also shows, compensations alone are no warranty of adequate and sustainable climate protection. He therefore suggests to use compensations to phase in a global licensing system, thereby mitigating the political obstacles associated with the implementation of such a licensing system which relate, particularly, to the distribution of emission permits. He arrives at the conclusion that lasting climate protection is only possible by proper development and joint and mutually supporting use of the two concepts. (orig.) [de

    Full text: The State of Qatar has become a member State of IAEA since 1974. Later the Department of Industrial Development (DID) beam the focal point and the competent authority regarding all aspects of the peaceful application of Nuclear Technology. In July, 2000 the Supreme Council was established and charged with all matters related to environmental protection. The Supreme Council joined the IAEA Projects on upgrading protection infrastructure in West Asia region. A preliminary research was initiated to discover where radiation sources are being used, and the legal framework, if any, to regulate their use. The research indicated that radiation sources were being used in the industrial practices (well logging, industrial radiography and nuclear gauges) and in medical practices (mainly diagnostic radiology). The research also indicated that there was virtually no legal framework to regulate them. In less than five years, the State of Qatar was able to issue the radiation protection law, three sets of regulations, namely: Radiation Protection Regulations, Radioactive Waste Management Regulations and the Safe Transport of Radioactive Materials Regulations. In addition, several specific regulation work, dose limits and radiation protection officers were issued. A radiation Protection Department, comprising three sections was established. We are providing individual exposure monitoring for most of the radiation workers in the public sector and some in the private sector. We have set up a proper licensing and inspections procedures, where our inspectors are enforcing the law. More recently, we established an early warning network for nuclear of radiological emergencies, consisting of 6 transplantable stations, five mobile stations and two navigating stations. This year, the network was augmented with five fixed station and an advanced early warning centre, which provides early warning via multiple means (MMS, Fax, E-mail and audio alarms).

    1985-01-01

    The structure of the existing legislation and its contents and aims are reconsidered. New rules which correspond to the present situation are to be established. Also the fundamental principles of the task and methods of radiation protection are to be changed. The main effort will be to create conditions so that all human beings will be protected against the harmful effects of radiation. The effects on plants, animals and on the environment should be considered as well. The legislation should include both ionizing and non-ionizing radiation. The main responsibility of protection should stay with the central authority. Licensing of apparatus, liability for medical applications and radioactive waste is discussed. Granting of permissions and control should be accomplished by the authority. Cooperation with other national and international authorities is dealt with. (G.B.)

    Radiation protection instrumentation plays very important role in radiation protection and surveillance programme. Radiation detector, which appears at the frontal end of the instrument, is an essential component of these instruments. The instrumental requirement of protection level radiation monitoring is different from conventional radiation measuring instruments. Present paper discusses the new type of nuclear radiation detectors, new protection level instruments and associated electronic modules for various applications. Occupational exposure to ionizing radiation can occur in a range of industries, such as nuclear power plants; mining and milling; medical institutions; educational and research establishments; and nuclear fuel cycle facilities. Adequate radiation protection to workers is essential for the safe and acceptable use of radioactive materials for different applications. The radiation exposures to the individual radiation workers and records of their cumulative radiation doses need to be routinely monitored and recorded

    Protection of induction motors is very important since they are widely used in industry for many applications due to their high robustness, reliability, low cost and maintenance, high efficiency and long service life. So, protecting these motors is crucial for operations. This paper presents a combined protection approach for induction motors. To achieve this, the electrical values of the induction motor were measured with sensitivity ±1% through a data acquisition card and processed with software developed in Visual C++. An on line protection system for induction motors was achieved easily and effectively. The experimental results have shown that the induction motor was protected against the possible problems faced during the operation. The software developed for this protection provides flexible and reliable media for operators and their motors. It is expected that the motor protection achieved in this study might be faster than the classical techniques and also may be applied to larger motors easily after small modifications of the software

  1. Time discounting and protected-area priorities.

    Should conservation organizations focus on protecting habitats that are at imminent risk of being converted but are expensive or more remote areas that are less immediately threatened but where a large amount of land can be set aside? Variants of this trade-off commonly arise in spatial planning. We examined this trade-off using models of land use change near a deforestation frontier. The optimal choice of where to protect was determined by how decisions taken today accounted for ecological benefits and economic costs of conservation actions that would occur sometime in the future. We used an ecological and economic discount rate to weight these benefits and costs. A large economic discount rate favored protecting more remote areas, whereas a large, positive ecological discount rate favored protecting habitat near the current deforestation frontier. We also showed how the decision over where to protect was impacted by the influence that economic factors had in determining landowners' decisions, the rate of technological change and ecological heterogeneity of the landscape. How benefits and costs through time are accounted for warrants careful consideration when specifying conservation objectives. It may provide a niche axis along which conservation organizations differentiate themselves when competing for donor funding or other support. This article is protected by copyright.

    Correlates between immunological parameters and protection against Bacillus anthracis infection in animals vaccinated with protective antigen (PA)-based vaccines could provide surrogate markers to evaluate the putative protective efficiency of immunization in humans. In previous studies we demonstrated that neutralizing antibody levels serve as correlates for protection in guinea pigs (S. Reuveny et al., Infect. Immun. 69:2888-2893, 2001; H. Marcus et al., Infect. Immun. 72:3471-3477, 2004). In this study we evaluated similar correlates for protection by active and passive immunization of New Zealand White rabbits. Full immunization and partial immunization were achieved by single and multiple injections of standard and diluted doses of a PA-based vaccine. Passive immunization was carried out by injection of immune sera from rabbits vaccinated with PA-based vaccine prior to challenge with B. anthracis spores. Immunized rabbits were challenged by intranasal spore instillation with one of two virulent strains (strains Vollum and ATCC 6605). The immune competence was estimated by measuring the level of total anti-PA antibodies, the neutralizing antibody titers, and the conferred protective immunity. The results indicate that total anti-PA antibody titers greater than 1 x 10(5) conferred protection, whereas lower titers (between 10(4) and 10(5)) provided partial protection but failed to predict protection. Neutralizing antibody titers between 500 and 800 provided partial protection, while titers higher than 1,000 conferred protection. In conclusion, this study emphasizes that regardless of the immunization regimen or the time of challenge, neutralizing antibody titers are better predictors of protection than total anti-PA titers.

    We review the general notion of topological protection of quantum states in spin models and its relation with the ideas of quantum error correction. We show that topological protection can be viewed as a Hamiltonian realization of error correction: for a quantum code for which the minimal number of errors that remain undetected is N, the corresponding Hamiltonian model of the effects of the environment noise appears only in the Nth order of the perturbation theory. We discuss the simplest model Hamiltonians that realize topological protection and their implementation in superconducting arrays. We focus on two dual realizations: in one the protected state is stored in the parity of the Cooper pair number, in the other, in the parity of the flux number. In both cases the superconducting arrays allow a number of fault-tolerant operations that should make the universal quantum computation possible. (key issues reviews)

  16. Strengthening the scientific basis of radiological protection

    The overarching objective of the radiological protection system is to contribute to an appropriate level of protection against the harmful effects of radiation exposure, without unjustifiably limiting the desired results from the human activity causing exposure. Such a balance is achieved by understanding as best as possible the scientific characteristics of radiation exposure and the related health effects, and by taking this knowledge into consideration when judging which protection decisions will ensure the best balance between social and economic aspects and risks. In general, the existing radiological protection system, on which national regulations are built in virtually every country in the world, works well and does not underestimate protection needs for either individuals or exposed populations as a whole. The latest International Commission on Radiological Protection (ICRP) recommendations, which define this protection system, were formed after a long and open dialogue with the public, where expert views were actively collected and discussed at national, regional and international levels. Although the radiological protection system is very effective, and there is no current need for a prompt revision, it is important nonetheless to keep a watchful eye on the latest scientific results, and to work to ensure that the entire radiological protection community is kept up to date on evolving and emerging scientific issues. In this way, potential or actual scientific changes can be appropriately identified and in turn can stimulate reflection on changes that might be needed in the protection system, in policy, in regulation and in practice. Such reflection should benefit from the input of other scientific disciplines and interested stakeholders. To contribute to this process, the NEA Committee on Radiological Protection and Public Health (CRPPH) has periodically reviewed and released reports on the state of the art in radiological protection science (see NEA

    Various governmental agencies, including the Ministry of Health, the Ministry of Labor and the Israel AEC are responsible for the control of the use of radioactive materials and medical X-ray machines in Israel. Present legislation deals mainly with the legal aspects of the purchase, transport and possession of radioactive materials and the purchase and operation of medical X-ray machines. No legislation refers explicitly to the protection of the worker from ionizing (and non-ionizing) radiation. A special group of experts appointed by the Minister of Labor recently worked out a comprehensive draft law concerning all legal aspects of occupational radiation protection in Israel. Among the main chapters of the draft are: general radiation protection principles, national radiation protection standards, medical supervision of radiation workers, personal monitoring requirements. The present situation with regard to radiation hazard control in Israel and details of the proposed radiation protection law is discussed. (Author)

    Radiation protection is a highly international dicipline with a high degree of international harmonization. Especially within the Nordic countries there is general agreement upon principles and standards, despite the actual practice may differ slightly. The basic recommendations of the International Commission on Radiological Protection (ICRP) are accepted by the regulatory bodies and should be followed by all users of radiation. The users are in principle responsible for the radiation protection standard and activities themselves. Because most companies or hospitals lack sufficient expertise by themselves, they must rely upon recommendations from others. Primarily they should contact the national radiation protection agency. However, due to the international harmonization of radiation protection, information from other national or international agencies may be used with confidence. All users of radiation in the Nordic countries are obliged to act according to recognition and assessment of both risks and benefits, and they are responsible for updating their knowledge
