    Under certain conditions, wether accidental or in nuclear reactor design, a nuclear reactor core may be found to be refrigerated by a fluid in natural circulation. Before the possible density waves phenomenon occurrence, it is essential to have a good knowledge of the flow evolution and thermohydraulic variables under these conditions. (Author) [es

  4. Nuclear power: Accidental releases - principles of public health action

    International Nuclear Information System (INIS)

    1984-01-01

    This report is based on the collective knowledge and experience of the members of a Working Group, convened by WHO in collaboration with the Government of Belgium in Brussels on 23-27 November 1981, to discuss and appraise the different actions that might be taken following accidental radioactive releases from nuclear plants. It does not provide detailed technical data, but broadly surveys the rational basis for decision-making, indicating the present position as assessed by members of the Working Group. Four major disciplines (radiological protection, health physics, environmental science and technology, and human biology) and three main professional categories (physicians, engineers and physicists) were represented, providing a comprehensive multidisciplinary approach to the topic. The purpose of this report is to give guidance to national authorities on how to develop the capacity to take action in a nuclear emergency

  5. Nuclear power: Accidental releases - practical guidance for public health action

    International Nuclear Information System (INIS)

    1987-01-01

    The disaster at Chernobyl, USSR, has caused a major crisis of confidence in nuclear safety, and highlighted the need for comprehensive contingency planning for - and emergency response to - such accidents. This report gives practical guidance on how the authorities should deal with an accident in any type of nuclear installation, whether it involves accidental releases to the air or into water. It is based on principles developed in a previous WHO report published in 1984. It summarizes the range of accidents for which plans need to be made to protect the public, the measures to be taken and the levels of dose at which they should be applied. It indicates how to measure the levels of exposure and what are the most likely routes of exposure. It then outlines the problems faced by public health authorities and medical practitioners, and the administrative arrangements that will have to be made. The example used is of a standard pressurized light water reactor of the type currently used for electricity generation, but many of the features will be common to other nuclear installations as well. This report is addressed to those organizations and individuals responsible for public health in the event of a nuclear accident. It will also be of use to those medical practitioners who are not administratively responsible in an accident, but who may need to be aware of the consequences and of the action to be taken in the aftermath of an accident. Coordination is vital between the public health administration and the organizations with direct responsibilities in the event of an accident, and this report is essential reading for them all. 29 refs, 2 figs, 7 tabs

  6. Effectiveness of cleanup criteria relative to an accidental nuclear release

    International Nuclear Information System (INIS)

    Chen, S.Y.; Yuan, Y.C.

    1988-01-01

    In the event of an accidental nuclear release, the associated long-term radiological risks would result primarily from ground contamination pathways. Cleanup of the contaminated ground surfaces is a necessary step toward reducing the radiological risk to the general population. Ideally, the radiological risk decreases as the level of cleanup effort increases; however, as the cleanup criterion (i.e., the required contaminant concentration after cleanup) becomes more stringent, the cleanup effort may become prohibitively costly. This study examines several factors that are important in determining the effectiveness of the cleanup criteria for selected radionuclides: (a) annual individual dose commitment (mrem/yr), (b) total population environmental dose commitment (person-rem), and (c) total area (km 2 ) requiring cleanup following an accident. To effectively protect the general population, the benefits of cleanup should be weighed against the potentially large increase in cleanup area (and the associated costs) as the cleanup criterion becomes more stringent. The effectiveness of cleanup will vary, depending largely on site-specific parameters such as population density and agricultural productivity as well as on the amount and type of radionuclide released. Determination of an optimum cleanup criterion should account for all factors, including a comprehensive cost/benefit analysis

    Natacci, Faustina Beatriz; Correa, Francisco

    2002-01-01

    The analysis of accidental sequences associated with the Containment is one of the most important tasks during the development of the Probabilistic Safety Assessment (PSA) of nuclear plants mainly because of its importance on the mitigation of consequences of severe postulated accident initiating events. This paper presents a first approach of the Containment analysis of the INAP identifying failures and events that can compromise its performance, and outlining accidental sequences and Containment end states. The initial plant damage states, which are the input for this study, are based on the event trees developed in the PSA level 1 for the INAP. It should be emphasized that since this PSA is still in a preliminary stage it is subjected to further completion. Consequently, the Containment analysis shall also be revised in order to incorporate, in an extension as complete as possible, all initial plant damage states, the corresponding event trees, and the related Containment end states. Finally, it can be concluded that the evaluation of the qualitative analysis presented herein allows a concise and broad knowledge of the qualitative analysis presented herein allows a concise and broad knowledge of the development of accidental sequences related to the Containment of the INAP.

    1996-11-01

    A knowledge model uses different techniques of complex systems management. Progress realised in the computer representation of links between different documents allows us to design a software facilitating the comprehension of the model built. This model is a qualitative model of the operators' behaviour in nuclear power plant accidental control. This model concerned three topics closely linked together. The first gives a description of every physical phenomena implied the application of the State-oriented Approach (APE in French) procedures. It's referred as model of process. The second gives a description of every activities used by the operators' team to manage all thermohydraulic incidents and accidents. It's a functional model also referred as tasks model. The quality of the method, based on the Systems' Science, capitalized a know-how simply transferable to design a new software on industrial process to support the operators. (author)

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models to simulation of tritium dispersion caused by an accident in a Candu reactor located in the ongoing Angra 3 site. The Candu reactor is one that uses heavy water (D 2 O) as moderator and coolant of the core. It was postulated, then, the LOCA accident (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 P Bq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m 3 ) during the first 14 days after the accident.

    1962-04-07

    The April 7, 1962 criticality accident involving human exposures was the first to have occurred in any production facility at Hanford. The accidental nuclear excursion did not result in any mechanical damage or spread of contamination. Three employees received over-exposure to gamma and neutron radiation. None were fatally exposed and in each case the over-exposure was recognized promptly. Following an initial period of medical observation and testing, the men were released to work. They continued to be followed clinically. Clinical studies performed were hematological procedures including leukocyte chromosome aberrations, morphologically aberrant blood cells, bone marrow evaluations, blood chemistry determinations, amino acid excretion studies, seminal fluid, urinary gonadotropins and estrogen excretion studies, testicular biopsies and crystalline lens examinations. These studies, along with a brief description of the accident and of the dosimetry, are summarized in this report by those participating in the studies. In view of the dose ranges received in these cases, both the negative and positive findings are considered to be of unusual interest due to the lack of knowledge of effects following human exposures at these levels.

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. This exercise was accomplished with the aid of a code system (SisBAHIA) developed in the Rio de Janeiro Federal University (COPPE/UFRJ). The CANDU reactor is one that uses heavy water (D 2 O) as moderator and coolant of the core. It was postulated, then, the LOCA (Loss of Coolant Accident) accident in the emergency cooling system of the nucleus (without fusion), where was lost 66 m 3 of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped and operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m 3 ) during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x10 9 to 5x10 5 Bq/m 3 close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value ( 3 ). (author)

    To assess the impacts of accidental radioactive releases to the hydrosphere from floating and land-based nuclear power plants, the Liquid Pathway Generic Study was initiated. The objective of this study was to compare the risks associated with releases through the liquid pathway from accidents that may reasonably be expected and those that are very improbable. Consequences were estimated in terms of radiation dose to man from drinking water ingestion, shell-fish and fish flesh consumption, and direct exposure (swimming, beach) as well as long-term effects, such as genetic effects or aquatic species degradation.

  5. Evidence Theory Based Uncertainty Quantification in Radiological Risk due to Accidental Release of Radioactivity from a Nuclear Power Plant

    International Nuclear Information System (INIS)

    Ingale, S. V.; Datta, D.

    2010-01-01

    Consequence of the accidental release of radioactivity from a nuclear power plant is assessed in terms of exposure or dose to the members of the public. Assessment of risk is routed through this dose computation. Dose computation basically depends on the basic dose assessment model and exposure pathways. One of the exposure pathways is the ingestion of contaminated food. The aim of the present paper is to compute the uncertainty associated with the risk to the members of the public due to the ingestion of contaminated food. The governing parameters of the ingestion dose assessment model being imprecise, we have approached evidence theory to compute the bound of the risk. The uncertainty is addressed by the belief and plausibility fuzzy measures.

    This thesis tackles a comprehensive analysis of the Plutonium situation and the contamination evolution, acquired during 33 years of studies in the Palomares area. Charter 2 contains a comprehensive description of the climatic characteristics, as well as the edaphologycal and economic situation of the area. The original contaminated plots and their evolution in 22 years are described, likewise, the vegetable species studied and the reason for their election re accounted for. A summary of the physical, chemical and radiological characteristics of plutonium is also included. Finally, the data contributed by other authors are analysed and compared with samples from Palomares. The first part of chapter 3 is focussed on the calculation of the americium and plutonium inventory, by means of a geoestatistic method applied to the measures of 36 polls carried out in 1986 down to a depth of 45 cm, in the area where the polluted material collected in the restoration tasks was provisionally stored. The second part of this chapter deals with the calculation of the isotopic composition of the material of the two bombs using different procedures. The samples identified as belonging to bomb 3 are also studied. The final part of this chapter analyses the migration speed of the plutonium oxide in Palomares, by means of several boreholes drilled in different years. Chapter 4 describes the experimental methodologies used to evaluate the behaviour, distribution and dispersion of the remaining contamination in the soil after 33 years, and the influence of environmental and anthropogenic factors on Pu, in order to evaluate the ways in which the contamination was incorporated into the food chains. The plutonium sequential leaching performed with soils from Palomares, using different reagents, was compared with other similar studies carried out in other places that are contaminated with different Pu sources. This comparison has allowed to evaluate the influence of the source term on the behaviour of the contamination. The study of the transuranic contamination in vegetables is tacked in Chapter 5. A comprehensive literature revision is made, and the data of the area are analysed to understand the evolution of the transuranic contamination associated with the peculiar circumstances of the local crops.

    and propose a reproducible approach for the evaluation of realistic indicators. Furthermore, these study shows that the data obtained on a nuclear site could apply to a nearby nuclear site, with close agro-climatic conditions. The influence of the types of productions and the agricultural and breeding practices, on the potential contamination of foodstuffs produced locally in accidental situation, led the IRSN to develop summary sheets on the agricultural environment of the nuclear sites. These levels of contamination can be very different according to the period of the year in which occurs the accident. For example, the date of harvest determines if these products will be almost exempt from contamination (so already harvested) or if they will present a maximal contamination. In complement, these sheets give some local contacts which would allow obtaining contextual precision around sensitive dates. These data will also allow elaborating sampling strategies to monitor foodstuffs activities after an accidental release. Based on these knowledge of environmental characteristics and considering that the metrological capacity will be necessarily limited, the monitoring strategies must insure that all foodstuff produced on the whole monitored area are below intervention levels.

    Full Text Available Chernobyl demonstrated that iodine-131 (131I released in a nuclear accident can cause malignant thyroid nodules to develop in children within a 300 mile radius of the incident. Timely potassium iodide (KI administration can prevent the development of thyroid cancer and the American Thyroid Association (ATA and a number of United States governmental agencies recommend KI prophylaxis. Current pre-distribution of KI by the United States government and other governments with nuclear reactors is probably ineffective. Thus we undertook a thorough scientific review, regarding emergency response to 131I exposures. We propose: (1 pre-distribution of KI to at risk populations; (2 prompt administration, within 2 hours of the incident; (3 utilization of a lowest effective KI dose; (4 distribution extension to at least 300 miles from the epicenter of a potential nuclear incident; (5 education of the public about dietary iodide sources; (6 continued post-hoc analysis of the long-term impact of nuclear accidents; and (7 support for global iodine sufficiency programs. Approximately two billion people are at risk for iodine deficiency disorder (IDD, the world’s leading cause of preventable brain damage. Iodide deficient individuals are at greater risk of developing thyroid cancer after 131I exposure. There are virtually no studies of KI prophylaxis in infants, children and adolescents, our target population. Because of their sensitivity to these side effects, we have suggested that we should extrapolate from the lowest effective adult dose, 15–30 mg or 1–2 mg per 10 pounds for children. We encourage global health agencies (private and governmental to consider these critical recommendations.

    Site specific radionuclide dispersion databases were archived for the emergency response to the hypothetical releases of 137 Cs from the Uljin nuclear power plant in Korea. These databases were obtained with the horizontal resolution of 1.5 km in the local domain centered the power plant site by simulations of the Lagrangian Particle Dispersion Model (LPDM) with the Unified Model (UM)-Local Data Assimilation Prediction System (LDAPS). The Eulerian Dispersion Model-East Asia (EDM-EA) with the UM-Global Data Assimilation Prediction System (UM-GDAPS) meteorological models was used to get dispersion databases in the regional domain. The LPDM model was performed for a year with a 5-day interval yielding 72 synoptic time-scale cases in a year. For each case hourly mean near surface concentrations, hourly mean column integrated concentrations, hourly total depositions for 5 consecutive days were archived by the LPDM model in the local domain and by the EDM-EA model in the regional domain of Asia. Among 72 synoptic cases in a year the worst synoptic case that showed the highest mean surface concentration averaged for 5 days in the LPDM model domain was chosen to illustrate the emergency preparedness to the hypothetical accident at the site. The simulated results by the LPDM model with the 137 Cs emission rate of the Fukushima nuclear power plant accident for the first 5-day period were found to be able to provide prerequisite information for the emergency response to the early phase of the accident whereas those of the EDM-EA model could provide information required for the environmental impact assessment of the accident in the regional domain. The archived site-specific database of 72 synoptic cases in a year could have a great potential to be used as a prognostic information on the emergency preparedness for the early phase of accident.

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models to simulation of tritium dispersion caused by an accident in a Candu reactor located in the ongoing Angra 3 site. The Candu reactor is one that uses heavy water (D{sub 2}O) as moderator and coolant of the core. It was postulated, then, the LOCA accident (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 P Bq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m{sup 3}) during the first 14 days after the accident.

    TEMAS (Techniques and Management Strategies for Environmental Restoration) is a user friendly decision aiding computerised system to help in th e selection of the best local strategy of restoration when a postaccidental environmental contamination with long lived radionuclides (''137 Cs, ''134 Cs and ''90 Sr) must be faced. TEMAS provides answer for complex scenarios (urban, agricultural and forest) with different specific levels of contamination, uses and dimensions. The computerized system is structured in three main modules: Databases containing those parameters required to identify and to provide results for typical potential cases of intervention (elemental cases); the evaluation module that uses a limited number of inputs to compose a virtual representation of the real contaminated scenario, in terms of elemental cases, and then calculates the required decision factors (residual individual doses, averted collective doses, costs and other secondary effects after each applicable intervention options); and the decision module which manages these factors according to a certain criteria to select and rank interventions as the recommended strategy. This document describes the contain of the databases, the main calculations of the different procedures and its correlation with databases, schematic draws of the fluxes of calculations, and one simulation of intervention to exemplify inputs and outputs of the system.

    This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. This exercise was accomplished with the aid of a code system (SisBAHIA) developed in the Rio de Janeiro Federal University (COPPE/UFRJ). The CANDU reactor is one that uses heavy water (D{sub 2}O) as moderator and coolant of the core. It was postulated, then, the LOCA (Loss of Coolant Accident) accident in the emergency cooling system of the nucleus (without fusion), where was lost 66 m{sup 3} of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped and operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m{sup 3} ) during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x10{sup 9} to 5x10{sup 5} Bq/m{sup 3} close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (< 11 kBq/m{sup 3}). (author)

    The accident frequency seems to increase rapidly, probably because of the industrial source use development. In opposition to that was noted twenty years ago, the accidents don't involve only the industrial firm or hospital wage earners but also public people. Serious accident analysis puts to the fore the defects which made them possible. The accidents due to energy production reactors are very seldom even if Chernobyl or nuclear submarine accidents have exposed about several hundreds workers to doses going beyond one gray. 78 refs. 17 figs. 14 tabs. 3 annexes

    A prototype version of a computer simulation system named JACOS (JAeri COgnitive Simulation system) has been developed at JAERI (Japan Atomic Energy Research Institute) to simulate the man-machine system behavior in which both the cognitive behavior of a human operator and the plant behavior affect each other. The objectives of this system development is to provide man-machine system analysts with detailed information on the cognitive process of an operator and the plant behavior affected by operator's actions in accidental situations of an NPP (nuclear power plant). The simulation system consists of an operator model and a plant model which are coupled dynamically. The operator model simulates an operator's cognitive behavior in accidental situations based on the decision ladder model of Rasmussen, and is implemented using the AI-techniques of the distributed cooperative inference method with the so-called blackboard architecture. Rule-based behavior is simulated using knowledge representation with If-Then type of rules. Knowledge-based behavior is simulated using knowledge representation with MFM (Multilevel Flow Modeling) and qualitative reasoning method. Cognitive characteristics of attentional narrowing, limitation of short-term memory, and knowledge recalling from long-term memory are also modeled. The plant model of a 3-loop PWR is also developed using a best estimate thermal-hydraulic analysis code RELAP5/MOD2. Some simulations of incidents were performed to verify the human model. It was found that AI-techniques used in the human model are suitable to simulate the operator's cognitive behavior in an NPP accident. The models of cognitive characteristics were investigated in the effects on simulated results of cognitive behaviors. (author)

    Full Text Available Here, we report studies on content and distribution of 137Cs and 90Sr artificial radionuclides in soil-vegetation cover at «Kraton 3» accidental underground nuclear explosion site. This site is located in the territory of northwestern Yakutia, within the northern taiga subzone of the permafrost-taiga region of eastern Siberia boreal belt. In geomorphological aspect, this object belongs to steep slope of the divide connecting the flood-lands of the Markha River and peneplain of the divide. Sod-carbonate (redzina soils prevail in soil cover of «Kraton 3» underground nuclear explosion site. This type of soil is typically characterized by a thin soil profile, weak alkaline reaction, heavy granulometric composition, saturated soil-absorbing complex, and drastically decreasing profile distribution of humus. Despite the considerable time after the accident, the radiation situation at the site is still very disturbing. Gamma ray background radiation levels at the site varied from 10 to 200 μR/h, which were 2–25 folds higher than average natural background radiation. The isotope contamination densities in soils of sites interconnected along the drainage were 34–1025 kBq/m2 for 137Cs and 57–781 kBq/m2 for 90Sr, which exceeded 30–1000 times the global fallout levels of these radionuclides. The rates of vertical migration of studied radionuclides were also determined as 0.11–0.84 % (137Cs and 0.79–1.44 % (90Sr per year of total radiation contamination density. The minimum vertical migration rates of 137Cs (0.11 % were observed in leached sod-carbonate soil, while maximum rates (0.84 % were determined in immature sod-carbonate soil, the profile of which lacks organogenic and humus-accumulative horizons. The migratory capabilities of 137Cs and 90Sr in this soil were very close and made 0.84 and 0.79 % respectively. Migration factors of 137Cs and 90Sr in permafrost soils of the studied area were determined with the use of principal component

    Models are described for use in site-specific environmental consequence analysis of nuclear reactor accidents of Classes 3 through 9. The models presented relate radioactivity released to resulting doses, health effects, and costs of remedial actions. Specific models are presented for the major exposure pathways of airborne releases, waterborne releases and direct irradiation from activity within the facility buildings, such as the containment. Time-dependent atmospheric dispersion parameters, crop production parameters and other variable parameters are used in the models. The environmental effects are analyzed for several accident start times during the year.

  8. Liquid pathway generic study. Impacts of accidental radioactive releases to the hydrosphere from floating and land-based nuclear power plants

    International Nuclear Information System (INIS)

    1978-02-01

    The staff concludes that for representative sites, there are differences in the impacts of accidental radioactive releases to the hydrosphere between floating nuclear plants (FNPs) and land-based plants (LBPs) of the ice-condenser type. The consequences of releases from design basis accidents are found to be lower for an FNP than for an LBP. For core-melt events which we consider to be of very low probability, the staff results indicate that the expected liquid pathway consequences are higher at an FNP than at an LBP, and that interdiction at the site is not likely for an FNP. The staff considers this combination of differences in release magnitude and interdiction potential to be significant. An assessment of the overall significance of the total risk associated with potential releases to liquid and airborne pathways will be considered in a forthcoming environmental impact statement for the FNP. This environmental impact statement will include a consideration of the environmental, social, and economic impacts of the operation of the FNP, as well as a value-impact analysis of alternatives which may avoid or mitigate radiological impacts to the environment

    Full text: The Atomic Energy Act, 1962 provides for the development of the peaceful uses of atomic energy for the welfare of the people in India. The licensing policy adopted for nuclear power stations in India requires that the plants meet stringent requirements based on the system of dose limitation, recommended by the International Commission of Radiological Protection (ICRP). Currently, nuclear energy is contributing just 3% of the country's power generation. The share of nuclear power is proposed to be increased to 10% in the near future. With the introduction of nuclear energy, the need to assess the radioecological and radiobiological impact of radionuclides of long half- life existing in the environment for longer duration has appeared. Tritium, a radioactive by-product of power reactors is one of such major radionuclides of concern. In the world, routine releases and accidental spills of tritium from nuclear power plants pose a growing health and safety concern. Tritium has been observed in ground water in the vicinity of several nuclear stations. Exposure to tritium has been clinically proven to cause deleterious and detectable effects such as teratogenesis, cancer and life shortening in laboratory animals. There is, now, a growing emphasis on tritium in radiation protection as the challenge of nuclear fusion comes nearer. Present investigation is an attempt to elucidate the effects of low dose tritiated water exposure on developing mouse cerebellum. Pregnant Swiss albino mice (12-15 in number were given a priming injection 7.4 and 74 kBq/ml of body water) of tritiated water (HTO) on 16 th day of gestation. From the same day onward, through parturition, till the last interval studied, the pregnant females were continuously maintained respectively on 11.1 and 111 kBq/ml of tritiated drinking water provided ad libidum. After cervical dislocation the litters were autopsied on 1, 3, 5 and 6 weeks post- partum. Brains were fixed and then cerebellum from each

    This white paper first states a set of fourteen recommendations regarding crisis management planning, post-accidental management planning, waste management, and the roles of CLIs (local information commissions) in crisis and post-accidental management planning. After an introduction which proposes a presentation of roles CLIs could play in the different stage of this planning (preparation, emergency or crisis, post-accidental), and a discussion of concerned territories, this white paper discusses territory zoning (zoning in situation of emergency, in post-accidental situation) and roles of territories and CLIs. The next part addresses the issue of decontamination: pollution and contamination management (territory decontamination, issue of water resources, waste management) and discusses the roles of territories and CLIs on these issues. The third part addresses the issue of support and protection of population regarding different aspects: census, relocation, continuity of public services, continuity of economic activities, food restrictions, medical follow-up and epidemiology, and compensations. The roles of territories and CLIs on these issues are discussed. The fourth part addresses the issues of information and communication in a crisis or post-accidental situation. The fifth part discusses tools and means needed by the CLIs to cope with these situations. Short contributions from different institutions (ASN, IRSN) and members of the ANCCLI are finally proposed

    This work is planned to simulate a scenario in which the same conditions that caused the accident at the Fukushima Daichi nuclear power plant are present, using a simulator of a nuclear power plant with VVER-1000 reactor, a different type of technology to the NPP where the accident occurred, which used BWR reactors. The software where it will take place the simulation was created and distributed by the IAEA for academic purposes, which contains the essential systems that characterize this type of NPP. The simulator has tools for the analysis of the characteristic phenomena of a VVER-1000 reactor in the different systems together and planned training tasks. This makes possible to identify the function of each component and how connects to other systems, thus facilitating the visualization of possible failures and the consequences that they have on the general behavior of the reactor. To program the conditions in the simulator, is necessary to know and synthesize a series of events occurred in Fukushima in 2011 and the realized maneuvers to reduce the effects of the system failures. Being different technologies interpretation of the changes that would suffer the VVER systems in the scenario in question will be developed. The Fukushima accident was characterized by the power loss of regular supply and emergency of the cooling systems which resulted in an increase in reactor temperature and subsequent fusion of their nuclei. Is interesting to reproduce this type of failure in a VVER, and extrapolate the lack of power supply in the systems that comprise, as well as pumping systems for cooling, has a pressure regulating system which involves more variables in the balance of the system.

    A knowledge model uses different techniques of complex systems management. Progress realised in the computer representation of links between different documents allows us to design a software facilitating the comprehension of the model built. This model is a qualitative model of the operators` behaviour in nuclear power plant accidental control. This model concerned three topics closely linked together. The first gives a description of every physical phenomena implied the application of the State-oriented Approach (APE in French) procedures. It`s referred as model of process. The second gives a description of every activities used by the operators` team to manage all thermohydraulic incidents and accidents. It`s a functional model also referred as tasks model. The quality of the method, based on the Systems` Science, capitalized a know-how simply transferable to design a new software on industrial process to support the operators. (author). 10 refs.

    The global context of my PhD thesis work is the optimization of air pollution monitoring networks, but more specifically it concerns the monitoring of accidental releases of radionuclides in air. The optimization problem of air quality measuring networks has been addresses in the literature. However, it has not been addresses in the context of surveillance of accidental atmospheric releases. The first part of my thesis addresses the optimization of a permanent network of monitoring of radioactive aerosols in the air, covering France. The second part concerns the problem of targeting of observations in case of an accidental release of radionuclides from a nuclear plant. (author)

    A Severe Accident in a nuclear power plant is a deviation from its normal operating conditions, resulting in substantial damage to the core and, potentially, the release of fission products. Although the occurrence of a Severe Accident on a nuclear power plant is a low probability event, due to the multiple safety systems and strict safety regulations applied since plant design and during operation, Severe Accident Analysis is performed as a safety proactive activity. Nuclear Power Plant Severe Accident Analysis is of great benefit for safety studies, training and accident management, among other applications. This work describes and summarizes some of the most important phenomena in Severe Accident field and briefly illustrates its potential use based on the results of two generic simulations. Equally important and abundant as those here presented, fission product transport and retention phenomena are deferred to a complementary work. (Author)

    From the beginning of 2002, Troyes prefecture has initiated a reflection about the management of a nuclear crisis caused by an accident at the Nogent-sur-Seine nuclear power plant. Five workshops have been created, dealing with the following themes: 'Administrative and economic organization', 'Health risk assessment and the epidemiology', 'Monitoring of environment', 'Movement in the contaminated area' and 'Decontamination of soil and Food chain'. The first results of the 'Decontamination of soil and Food chain' working group, which involves the District Agricultural and Forestry Department, the Farmer's Association, the Institute for Radiological Protection and Nuclear Safety and the Veterinary Division are presented in the poster. The scenario that had been developed for the accident considers the release of 3 radionuclides ( 131 I, 134 Cs and 137 Cs) in the environment. The scale of the crisis didn't require the evacuation and the sheltering of the population during the emergency phase. The consequences on the local agricultural products (cereal, beetroot, vine, milk, cow meat...) have been assessed up to 50 km and different strategies of agricultural countermeasures have been studied regarding to the local constraints (soil types, surfaces and quantities concerned) and to the consequences of their implementation (waste types and quantities, costs). Then, decision-making diagrams summed up the technical results and allowed to deepen the global thought. (author)

    Yoshida, Kazuo; Tanabe, Fumiya; Kawase, Katumi.

    1996-01-01

    It has been proposed to use the Multilevel Flow Modeling (MFM) by M. Lind as a framework for functional knowledge representation for qualitative reasoning in a complex process system such as nuclear power plant. To build a knowledge base with MFM framework makes it possible to represent functional characteristics in different levels of abstraction and aggregation. A pilot inference system based on the qualitative reasoning with MFM has been developed to diagnose a cause of abnormal events in a typical PWR power plant. Some single failure events has been diagnosed with this system to verify the proposed method. In the verification study, some investigation has been also performed to clarify the effects of this knowledge representation in efficiency of reasoning and ambiguity of qualitative reasoning.

    Current distributions of artificial radionuclides (ARN) were studied in the main compartments of a larch-tree forest lethally affected by a radioactive release from the Kraton-3 peaceful underground nuclear explosion (65.9 deg N, 112.3 deg E; Yakutia, Russia; 1978). Samples of soil, fungi, lichens, mosses, grasses, shrubs and trees were obtained at points belonging to four zones categorised by the severity of the ecosystem damage. Sampling was supplemented by dose rate measurements in air and mapping. The area of forest characterised by 100% lethality to adult larches (Larix gmelinii) and with partial, visually-detectable damage of other more radio-resistance species (e.g. lichens, mosses) covers a territory of approximately 1.2 km 2 . Elevated levels of long-lived ARN were found at all sampling sites. Maximum registered levels of the ground contamination with radionuclides of Cs, Sr and Pu were three orders of magnitude higher than those expected from global fallout. The ratios of 137 Cs to some other significant radionuclides in the ground contamination were as follows [mean (range)]: 90 Sr - 0.57(0.02-0.93); 239,240 Pu 44(25-72); 60 Co 470(220-760). Twenty-three years after a discrete contamination event, 90-95% of the total deposited radiocesium and plutonium has still remained in the lichen-moss on-ground cover and in the top 5 cm organic soil layer. At the same time, vertical and horizontal migrations of 90 Sr in soil were more pronounced. Strong surface contamination with 137 Cs, 90 Sr and plutonium was detected at the twigs and bark of the dead larches. The young larches that grew at the contaminated area following the initial destruction of the forest demonstrated a substantial ability to accumulate 137 Cs, 90 Sr and plutonium via roots, while the bushes selectively accumulated mainly radiostrontium. In contrast, some fungi concentrated mostly radiocesium. The levels of gamma dose rate in air and the environmental contamination with 137 Cs were found to

    The greatest fear of the population before a nuclear accident, is the radiological impact to the health of people, due to the exposure to the liberated radioactive material during the accident, this fear is generally exaggerated or not well managed by the media. The best estimate in the received doses and their possible effects is carried out based on the information obtained during a certain time after the accident event. This work contains a summary of the information in the topic that at the present time has presented institutions as: the World Health Organization (Who), the United Nations Scientific Committee on Effects of Atomic Radiation (UNSCEAR), the Nuclear Regulatory Commission (NRC) and the World Nuclear Association, among others. The considered accidents are: first, the Unit-2 of the nuclear power plant of the Three Mile Island in Pennsylvania, USA occurred 28 March of 1979, in the Reactor TMI-2, type PWR of 900 M We; the second accident was 26 April of 1986, in the Unit-4 of the nuclear power plant of Chernobyl, in Ukraine, the involved reactor was type BRMK, of 1000 M We moderated by graphite and cooled with light water, the power plant is located to 100 Km to the northwest of Kiev; 25 years later occurred the third accident in the nuclear power plant of Fukushima Dai-ichi, in Japan, affecting at four of the six reactors of the power plant. A brief description of the accident is presented in each case, including the magnitude of the provoked liberations of radioactive material, the estimate doses of the population and the affected workers are presented, as well as the possible consequences of these doses on the health. The objective of this diffusion work is to give knowledge to the nuclear and radiological community of the available information on the topic, in order to be located in the appropriate professional context.

    EDF ordered to FRAMATOME by 1977 to complete post accidental long term studies on 'First Contrat-Programme' reactors, in order to demonstrate the safety criteria long term compliance, to get information on NSSS behaviour and to improve the post accidental procedures. Convenient analytical models were needed and EDF and FRAMATOME respectively developped the AXEL and FRARELAP codes. The main results of these studies is that for the smallest breaks, it is possible to manually undertake cooling and pressure reducing actions by dumping the steam generators secondary side in order to meet the RHR operating specifications and perform long term cooling through this system. A specific small breaks procedure was written on this basis. The EDF and FRAMATOME codes are continuously improved; the results of a French set of separate effects experiments will be incorporated as well as integral system verification

    We describe a case of a 43-yr-old female with severe multiorgan injury after accidental poisoning with Colchicum autumnale, which was mistaken for wild garlic (Allium ursinum). Both plants grow on damp meadows and can be confused in the spring when both plants have leaves but no blossoms. The autumn crocus contains colchicine, which inhibits cellular division. Treatment consisted of supportive care, antibiotic therapy, and granulocyte-directed growth factor. The patient was discharged from the hospital after three weeks. Three years after recovery from the acute poisoning, the patient continued to complain of muscle weakness and intermittent episodes of hair loss.

    2011-01-01

    Complete text of publication follows. The possible risk of an unexpected nuclear accident or violent terror attack necessitates different methods and processes potentially applicable in emergency. After the event fast and reliable dose assessments should be given so that arrangements and intervention could start as soon as possible. Retrospective dosimetry is one of the most important tool of accidental dosimetry for dose estimation when dose measurement was not planned and there is no dose data available as a result of a nuclear accident. Luminescent materials are suitable for retrospective dosimetry using TL and/or OSL analysis. Several materials have luminescence properties in the environment, but in the situation mentioned it is suggested to use not just natural substances, but also personal belongings carried by victims, who received the dose. In our environment many objects can be applied as natural dosimeters, having suitable thermoluminescent (TL) and optically stimulated luminescent (OSL) properties. The paper discusses the recent developments, the analysis of luminescence and the dose response curves of various electronic components and the common (table) salt (NaCl) using Daybreak TL reader for retrospective dosimetry purposes. Basic TL properties of these materials (e.g. fading and reproducibility) have also been investigated and will be shown in this study.

    Removal half-life (RHL) of tritium is one of the best means for optimising medical treatment, reduction of committed effective dose (CED) and quick/easy handling of a large group of workers for medical treatment reference. The removal of tritium from the body depends on age, temperature, relative humidity and daily rainfall; so tritium removal rate, its follow-up and proper data analysis and recording are the best techniques for management of accidental acute tritium exposed cases. The decision of referring for medical treatment or medical intervention (MI) would be based on workers' tritium RHL history taken from their bodies at the facilities. The workers with tritium intake up to 1 ALI shall not be considered for medical treatment as it is a derived limit of annual total effective dose. The short-term MI may be considered for tritium intake of 1-10 ALI; however, if the results show intake ≥100 ALI, extended strong medical/therapeutic intervention may be recommended based on the severity of exposure for maximum CED reduction requirements and annual total effective dose limit. The methodology is very useful for pressurized heavy water reactors (PHWRs) which are mainly operated by Canada and India and future fusion reactor technologies. Proper management will optimise the cases for medical treatment and enhance public acceptance of nuclear fission and fusion reactor technologies.

    1984-01-01

    A series of 51 fatal cases of accidental hypothermia in northern Sweden has been reviewed. The cases conform well to previous investigations with respect to the mean age of the victims (48 years) and a predominance of males. The cases occurred mainly during the winter months and on Saturdays. Most cases succumbed at temperatures below -10 degrees C. The most frequent necropsy findings were areas of frostbite with purple discoloration of the skin, reddish lividity and superficial erosions of the gastric mucosa. Paradoxical undressing was present in more than half of the cases. About two thirds of the cases were under the influence of alcohol with a mean blood alcohol concentration of 1.6 g/l. Furthermore, at least half of the cases could be considered habitual drunkards. In conclusion, the present series shows two main groups of fatal hypothermia victims: one group of elderly persons, mostly chronic abusers and under the influence of alcohol (approximately two-thirds of the series), and another of younger and sober persons, performing recognised sporting activities (approximately one-fourth of the series).

    Hypothermia in colder climates in the United States occurs predominately as a result of exposure of alcoholics to cold outdoor temperatures. Among 24 cases of accidental hypothermia occurring at a university medical center in the deep South, differences in clinical presentation were identified. In contrast to experience in colder climates, 17/22 cases (76%) developed at home. Alcohol was a factor in only 8/24 (33%). The elderly were at greatest risk, accounting for 16/24 patients (65%). Factors suggested to account for the high incidence of hypothermia in the elderly include abnormal temperature perception or regulation, intercurrent illness, social isolation, inadequate housing, and poverty. Coexisting medical conditions were identified as a potential cause of hypothermia in only 10/24 of these patients (42%). Social isolation was not a strong predictor, with 6/17 of the elderly (35%) living alone. Death occurred in 9/24 patients (37%), but survival could not be predicted from admission temperature, hypotension, anemia, or serum glucose. Since extreme cold temperatures are infrequent in the deep South, identified differences in demographics may be due to inadequate housing or lack of preparation for cold weather dangers.

Even a low dose can already be potentially lethal. Patients are conventionally treated with hemodialysis. Therefore we'd like to present a report of a foreign sailor in Rotterdam who accidentally caused himself severe methanol intoxication, with a maximum measured concentration of 4.4 g/L. Case presentation The patient presented with hemodynamic instability and severe metabolic acidosis with pH 6.69. The anion gap was 39 mmol/L and the osmol gap 73 mosmol/kg. Treatment with ethanol and continuous venovenous hemodiafiltration (CVVH-DF was initiated. Despite the hemodynamic instability it is was possible to achieve rapid correction of pH and methanol concentration with CVVH-DF while maintaining a stable and therapeutic ethanol serum concentration. Despite hemodynamic and acid-base improvement, our patient developed massive cerebral edema leading to brain death. Permission for organ donation was unfortunately not ascertained. Conclusions We conclude that in a hemodynamic instable situation high methanol concentrations and methanol-induced derangements of homeostasis are safely and effectively treated with CVVH-DF and that severe cerebral edema is another possible cause of death rather than the classical bleeding in the putamen area.

    Although accidents involving the release of radioactive materials and the unplanned exposure of people can occur at any stage of the nuclear fuel cycle, most attention has been focused on reactor accidents. Although no power reactor accidents involving exposure of the public have yet occured, it should be recognized that the probability of such accidental releases cannot be reduced to zero. Since the inventory of radioactive materials in power reactors is very large, it is usual to postulate, for safety assessments, that a release of fission products takes place in spite of all protective measures. This postulated release is of importance for reactor siting and for preparing emergency plans. (HP) [de

    One result of the workshop was, that even in the case of severe accident sequences in modern nuclear power plants (other facilities were not discussed), there will be enough time to take active measures in order to lower the emissions and to diminish the consequences inside and outside of the plant. On the whole, new evidence from Harrisburg show that previously estimated accidental emissions, especially of radiologically relevant nuclides, have been rather conservative and that much lower emissions are possible, if the above measures are considered. Under accident conditions, models to predict radiation exposure must be applied under the event of a short-term release. (orig./DG) [de

    An increasing number of drugs of abuse are sold word wide over the internet. Names like "legal highs", "herbal highs" etc. give the impression that these are safe products, although the risk of fatal reactions might be substantial. Leaves from the plant Mitragyna speciosa, contain active compounds like mitragynine and 7-hydroxymitragynine. It has been reported that the potency of 7-hydroxymitragynine at the μ-opioid receptor is 30 times higher than that of mitragynine and 17 times higher than that of morphine. Case reports regarding poisoning with Kratom are reported, but the toxic or lethal ranges for the concentrations of the active substances have not been established, and concentrations of 7-hydroxymitragynine have not been reported previously. We present a case report where a middle aged man was found dead at home. The deceased had a history of drug abuse and mental illness for several years. At autopsy, there were no significant pathological findings. Post-mortem analysis of peripheral blood revealed: zopiclone 0.043mg/L, citalopram 0.36mg/L and lamotrigine 5.4mg/L, i.e. concentrations regularly seen after therapeutic ingestion of these drugs. Additionally mitragynine 1.06mg/L and 7-hydroxymitragynine 0.15mg/L were detected in blood and both also in urine. The high concentrations of mitragynine and 7-hydroxymitragynine indicate that the cause of death is intoxication by these substances; and the circumstances point toward the manner of death being accidental. We recommend that both mitragynine and 7-hydroxymitragynine are analyzed for in cases with suspected Kratom intoxication. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available La mortalidad global por accidente cerebrovascular (ACV ha disminuido en las últimas tres décadas, probablemente debido a un mejor control de los factores de riesgo vascular. La mortalidad hospitalaria por ACV ha sido tradicionalmente estimada entre 6 y 14% en la mayoría de las series comunicadas. Sin embargo, los datos de ensayos clínicos recientes sugieren que esta cifra sería sustancialmente menor. Se revisaron datos de pacientes internados con diagnóstico de ACV del Banco de Datos de Stroke de FLENI y los registros institucionales de mortalidad entre los años 2000 y 2010. Los subtipos de ACV isquémicos se clasificaron según criterios TOAST y los ACV hemorrágicos en hematomas intrapanquimatosos, hemorragias subaracnoideas aneurismáticas, malformaciones arteriovenosas y otros hematomas intraparenquimatosos. Se analizaron 1514 pacientes, 1079 (71% con ACV isquémico (grandes vasos 39%, cardioembólicos 27%, lacunares 9%, etiología indeterminada 14%, otras etiologías 11% y 435 (29% con ACV hemorrágico (intraparenquimatosos 27%, hemorragia subaracnoidea 30%, malformaciones arteriovenosas 25% y otros hematomas espontáneos 18%. Se registraron 38 muertes intrahospitalarias (17 ACV isquémicos y 21 ACV hemorrágicos, representando una mortalidad global del 2.5% (1.7% en ACV isquémicos y 4.8% en ACV hemorrágicos. No se registraron muertes asociadas al uso de fibrinolíticos endovenosos. La mortalidad intrahospitalaria en pacientes con ACV isquémico y hemorrágico en nuestro centro fue baja. El manejo en un centro dedicado a las enfermedades neurológicas y el enfoque multidisciplinario por personal médico y no médico entrenado en el cuidado de la enfermedad cerebrovascular podrían explicar, al menos en parte, estos resultados.

    Environmental assessment models are used for evaluating the radiological impact of actual and potential releases of radionuclides to the environment. They are essential tools for use in the regulatory control of routine discharges to the environment and also in planning measures to be taken in the event of accidental releases. They are also used for predicting the impact of releases which may occur far into the future, for example, from underground radioactive waste repositories. It is important to verify, to the extent possible, the reliability of the predictions of such models by a comparison with measured values in the environment or with predictions of other models. The IAEA has been organizing programmes of international model testing since the 1980s. These programmes have contributed to a general improvement in models, in the transfer of data and in the capabilities of modellers in Member States. IAEA publications on this subject over the past three decades demonstrate the comprehensive nature of the programmes and record the associated advances which have been made. From 2009 to 2011, the IAEA organized a programme entitled Environmental Modelling for RAdiation Safety (EMRAS II), which concentrated on the improvement of environmental transfer models and the development of reference approaches to estimate the radiological impacts on humans, as well as on flora and fauna, arising from radionuclides in the environment. Different aspects were addressed by nine working groups covering three themes: reference approaches for human dose assessment, reference approaches for biota dose assessment and approaches for assessing emergency situations.

    A non-LTR TRAS retrotransposon (identified as TRASAp1) has been amplified in the pea aphid Acyrthosiphon pisum and its presence has been assessed also in the peach potato aphid Myzus persicae. This TRAS element possesses 2 overlapping ORFs (a gag-ORF1 and a pol-ORF2 containing the reverse transcriptase and the endonuclease domains) that show a similarity ranging from 40% to 48% to proteins coded by other TRAS elements identified in insects (including the beetle Tribolium castaneum and the moth Bombyx mori). The study of the TRAS chromosomal insertion sites, performed by standard fluorescent in situ hybridization (FISH) and fiber FISH, showed that TRAS elements were located in a subtelomeric position, just before the telomeric (TTAGG) n repeats. In both the aphid species, TRAS elements were present at all termini of autosomes, but the 2 X chromosome telomeres show a clear-cut structural difference. Indeed, cromomycin A3 staining, together with FISH using a TRAS probe, revealed that TRAS signals only occur at the telomere opposite to the NOR-bearing one. Lastly, the analysis of the distribution of TRAS retrotransposons in a M. persicae strain possessing spontaneous fragmentations of the X chromosomes assessed that TRAS elements were not involved in the healing of de novo telomeres.

    The present work aims to recreate the accident occurred at the Fukushima Daiichi nuclear power plant in Japan on March 11, 2011, making use of an academic simulator of forced circulation of the A BWR reactor provided by the IAEA to know the scope of this simulator. The simulator was developed and distributed by the IAEA for academic purposes and contains the characteristics and general elements of this reactor to be able to simulate transients and failures of different types, allowing also to observe the general behavior of the reactor, as well as several phenomena and present systems in the same. Is an educational tool of great value, but it does not have a scope that allows the training of plant operators. To recreate the conditions of the Fukushima accident in the simulator, we first have to know what events led to this accident, as well as the actions taken by operators and managers to reduce the consequences of this accident; and the sequence of events that occurred during the course of the accident. Differences in the nuclear power plant behavior are observed and interpreted throughout the simulation, since the Fukushima plant technology and the simulator technology are not the same, although they have several elements in common. The Fukushima plant had an event that by far exceeded the design basis, which triggered in an accident that occurred in the first place by a total loss of power supply, followed by the loss of cooling systems, causing a level too high in temperature, melting the core and damaging the containment accordingly, allowing the escape of hydrogen and radioactive material. As a result of the simulation, was determined that the scope of the IAEA academic simulator reaches the entrance of the emergency equipment, so is able to simulate almost all the events occurred at the time of the earthquake and the arrival of the tsunami in the nuclear power plant of Fukushima Daiichi. However, due to its characteristics, is not able to simulate later

    This report describes a protocol for managing the accidental swallowing of dental instruments in implant dentistry, illustrated by a patient who accidentally swallowed a hexagonal wrench. The first step was to refer the patient to the medical emergency hospital service for radiographic and clinical evaluation. The hexagonal wrench was located in the stomach and was immediately removed with an endoscopic procedure. The gastric mucosa was sampled via biopsy and the sample submitted to the urease test, which was positive for Helicobacter pylori. Triple treatment was instituted for gastritis caused by H pylori to avoid exposing the patient to unnecessary risk. Removal of a foreign body by means of an endoscopic procedure constitutes a safe and effective treatment. Copyright © 2015 Editorial Council for the Journal of Prosthetic Dentistry.

    Accidental river pollution can cause damage to the environment, put at risk the health of people that use the water for domestic purposes, and, not lastly, compromise dependent economic activities (e.g., agriculture). The reduction of the concentration of pollutant on any river following an accidental pollution can be achieved using dilution, by opening for certain duration the bottom gates of the reservoirs placed on the river's tributaries and releasing a significant volume of clean water in the main river. The hydraulic simulation and the pollutant transport are executed, firstly considering there is no dilution and secondly for the dilution scenario (bottom gates of the reservoirs open). A database was created, containing the results of simulations of pollutant transport for various values of the pollution characteristics in both diluted/undiluted scenarios. The database served for the implementation of a web decision support tool that presents an intuitive and easy to use GUI that allows the user to input details of the accidental pollution. Straightforward actions to be taken are presented to the end-user (e.g., "Open the bottom gates of the reservoir X at time T1 and close it at time T2") and synchronized charts show the effect of the dilution in respect to the concentration of pollutant at certain locations on the river. Using the described approach, a reduction of pollutant concentration in the river with up to 90% can be obtained.

    A meso-scale wind field forecast model was designed for emergency environmental assessment in case of accidental release of radiative materials from a nuclear power station. Actual practice of the model showed that it runs fast, has wind field prediction function, and the result given is accurate. With meteorological data collected from weather stations, and pre-treated by a wind field diagnostic model, the initial wind fields at different times were inputted as initial values and assimilation fields for the forecasting model. The model, in turn, worked out to forecast meso-scale wind field of 24 hours in a horizontal domain of 205 km x 205 km. And then, the diagnostic model was employed again with the forecasting data to obtain more detail information of disturbed wind field by local terrain in a smaller domain of 20.5 km x 20.5 km, of which the nuclear power station is at the center. Using observation data in January, April, July and October of 1996 over the area of Hangzhou Bay, wind fields in these 4 months were simulated by different assimilation time and number of the weather stations for a sensitive test. Results indicated that the method used here has increased accuracy of the forecasted wind fields. And incorporating diagnostic method with the wind field forecast model has greatly increased efficiency of the wind field forecast for the smaller domain. This model and scheme have been used in Environmental Consequence Assessment System of Nuclear Accident in Qinshan Area

    Bone marrow aplasia is one of the main syndromes following a high dose accidental radiation exposure. Whilst transfusion and bone marrow transplantation have been used with some success starting with the first treatments of accident victims, other therapeutic strategies are needed. With the development of experimental and clinical haematology, promising new approaches to the treatment of aplasia have appeared. New trends for the treatment of haemopoietic injury based on bone marrow transplantation rely on new sources of compatible donor cells, such as cord blood, on the selection of immature haemopoietic cells and on new transplant regimens. Haemopoietic growth factors stimulate the proliferation and/or differentiation of haemopoietic progenitors and, possibly, stem cells. Furthermore, they act on the functions of mature cells. Currently, they have specific uses in haematology related to their role in the regulation of growth and in the differentiation of haemopoietic progenitor cells. Growth factors have already been used for the treatment of accidental radiation induced aplasia and lessons have been learned from their medical management and followup. (author)

    Full Text Available Accidental radioisotope burns are rare. The major components of radiation injury are burns, interstitial pneumonitis, acute bone marrow suppression, acute renal failure and adult respiratory distress syndrome. Radiation burns, though localized in distribution, have systemic effects, and can be extremely difficult to heal, even after multiple surgeries. In a 25 year old male who sustained such trauma by accidental industrial exposure to Iridium192 the early presentation involved recurrent haematemesis, pancytopenia and bone marrow suppression. After three weeks he developed burns in contact areas in the left hand, left side of the chest, abdomen and right inguinal region. All except the inguinal wound healed spontaneously but the former became a non-healing ulcer. Pancytopenia and bone marrow depression followed. He was treated with morphine and NSAIDs, epidural buprinorphine and bupivicaine for pain relief, steroids, antibiotics followed by wound excision and reconstruction with tensor fascia lata(TFL flap. Patient had breakdown of abdominal scar later and it was excised with 0.5 cm margins up to the underlying muscle and the wound was covered by a latissimis dorsi flap.

    Uranium Hexafluoride is a material used in the various processes which comprise the front end of the nuclear fuel cycle (conversion, enrichment and fuel fabrication). Confinement of UF 6 is a very important safety requirement since this material is highly reactive and presents safety hazards to humans. The present paper discusses the safety relevant aspects of accidental releases of UF 6 inside process confinement buildings. Postulated accidental scenarios are analyzed and their consequences evaluated. Implant releases rates are estimated using computer code predictions. A time dependent homogeneous compartment model is used to predict concentrations of UF 6 , hydrogen fluoride and uranyl fluoride inside a confinement building, as well as to evaluate source terms released to the atmosphere. These source terms can be used as input to atmospheric dispersion models to evaluate consequences to the environment. The results can also be used to define adequate protective measures for emergency situations. (author)

  19. Is the tri-bimaximal mixing accidental?

    CERN Document Server

    Abbas, Mohammed

    2010-01-01

    The Tri-bimaximal (TBM) mixing is not accidental if structures of the corresponding leptonic mass matrices follow immediately from certain (residual or broken) flavor symmetry. We develop a simple formalism which allows one to analyze effects of deviations of the lepton mixing from TBM on structure of the neutrino mass matrix and on underlying flavor symmetry. We show that possible deviations from the TBM mixing can lead to strong modifications of the mass matrix and strong violation of the TBM mass relations. As a result, the mass matrix may have an "anarchical" structure with random values of elements or it may have some symmetry which differs from the TBM symmetry. Interesting examples include matrices with texture zeros, matrices with certain "flavor alignment" as well as hierarchical matrices with a two-component structure, where the dominant and sub-dominant contributions have different symmetries. This opens up new approaches to understand the lepton mixing.

  20. Accidental Turbulent Discharge Rate Estimation from Videos

    Science.gov (United States)

    Ibarra, Eric; Shaffer, Franklin; Savaş, Ömer

    2015-11-01

    A technique to estimate the volumetric discharge rate in accidental oil releases using high speed video streams is described. The essence of the method is similar to PIV processing, however the cross correlation is carried out on the visible features of the efflux, which are usually turbulent, opaque and immiscible. The key step in the process is to perform a pixelwise time filtering on the video stream, in which the parameters are commensurate with the scales of the large eddies. The velocity field extracted from the shell of visible features is then used to construct an approximate velocity profile within the discharge. The technique has been tested on laboratory experiments using both water and oil jets at Re ~105 . The technique is accurate to 20%, which is sufficient for initial responders to deploy adequate resources for containment. The software package requires minimal user input and is intended for deployment on an ROV in the field. Supported by DOI via NETL.

    The clinical progression following a sulfur mustard-induced skin exposure is well documented in the literature. Upon skin contact and a characteristic latency period, sulfur mustard (SM) causes erythema, blister formation and ulceration, which is associated with wound healing disorders that may require surgical treatment. Here, we present a case report of accidental exposure to SM in a laboratory setting which required surgical treatment of the skin. The case was illustrated at close intervals over a period of two years and underlines that exposure to SM has to be taken into account when typical clinical symptoms occur. Moreover skin grafts appear to be effective in SM-induced non healing skin ulcerations. Copyright © 2017 Elsevier B.V. All rights reserved.

    The case reported involved a 60-year-old man with psychiatric illness who was found dead at his home. He was almost naked and showed signs of death by violent asphyxiation, which led to the suspicion of homicide. Autopsy findings showed foreign material in the trachea and larynx. However, the partially digested content in his stomach, the study of the gastric content and the microscopic analysis of the airways made it possible to define this as accidental death due to inhalation of material from a diaper. Toxicological analysis detected the presence of phenytoin, valproic acid, and phenobarbital in his blood, with values within the therapeutic ranges. This is certainly a peculiar case, as particularly evident after careful review of the literature on deaths by asphyxiation in psychiatric patients. Furthermore, this study highlights the importance of a full autopsy and microscopic evaluation of any foreign bodies.

    Full Text Available How do we define, discuss or assess aesthetics within a contemporary philosophical framework? The indefiniteness that accompanies attempts to formalize a definition of the aesthetic is a primary focus of this paper. This lack of a definition has occupied philosophers for hundreds of years in attempts to delineate the boundaries of an elusively formless concept. This formlessness speaks to the incredibly evasive character of such a pervasive feature recognized in both natural and artificial systems, agents and artefacts. With the rapid growth of artificially intelligent systems and an astounding diversity in computational creativity, in what ways may we approach aesthetics? How is the aesthetic recognized, determined and produced? This paper seeks to critically engage issues of non-human agency, inter-object relations, and aesthetic theory in relation to computational entities and autonomous systems. The ability of these systems to operate outside of human cognitive limitations including thought patterns and constructions which may preclude alternative aesthetic outcomes, afford them in some ways limitless potential in relation to aesthetics. The designation of the accidental or provisional is utilized as an alternative approach to the production and assessment of aesthetic occurrences of the non-human.

  17. External hazards in the PRA of Olkiluoto 1 and 2 NPP units - Accidental oil spills

    2014-01-01

    Oil transports in Finnish territorial waters have increased significantly during the last 10 years. The Gulf of Finland is at this moment a very important route of oil being transported from Russia to the Western Europe. Although the number of accidental oil spills is decreasing in amount and in size, there is a growing concern of their effects to nuclear power plants (NPPs). The amounts of oil transported on the Gulf of Bothnia are much smaller than on the Gulf of Finland. However, accidental oil spills have occurred also there, the size and amount of which are smaller, though. Accidental oil spills are often a result of grounding of a ship or collision of two ships, and often occur during harsh weather conditions like storm or dense fog. However, also coastal oil depots may break, the oil of which may spread over wide distances on the sea. The modelling of initiating events resulting from accidental oil spills includes oil spill response actions performed by the regional rescue services, alarming of the oil spill by the emergency response centre to the NPP rescue services and spill response by the NPPs rescue services. It is unclear what the consequences are if drifted oil would enter the coolant water tunnels. The effect of different oil types to the operation of the safety-related service water systems and components are being assessed. In the ultimate case, an oil spill would clog the inlet channels thus failing the ultimate heat sink of the NPP units. The licensee is evaluating what is the optimal way to operate the NPP units in the case that an oil slick is threatening the plant to ensure reactor core cooling and RHR. The continued operation of, and especially the cooling of, at least one auxiliary feedwater pump is critical in the mitigation of the initiating event. Strategies, like reversing the water flow of the cooling water channels or closing of the cooling water channels, are being evaluated. (authors)

    The advance made in the nuclear security evaluation of the CAREM reactor is presented. It was carried out using the Security Probabilistic Analysis (SPA). The latter takes into account the different phases of identification and solution of initiating events and the qualitative development of event trees. The method of identification of initiating events is the Master Logical Diagram (MLD), whose deductive basis makes it appropriate for a new design like the one described. The qualitative development of the event trees associated to the identified initiating events, allows identification of those accidental sequences which are to have the security systems in the reactor.

  1. Lessons learned from accidental exposures in radiotherapy

    International Nuclear Information System (INIS)

    2000-01-01

    The medical use of radiation is unique in that patients are intentionally exposed to radiation. The aim in radiation therapy is twofold: to deliver a dose and dose distribution that is adequate for tumour control, but which also minimizes complications in normal tissues. In therapeutic applications, the doses are high and a deviation from the prescribed dose may have severe or even fatal consequences. There is therefore a great need to ensure adequate radiation protection and safety in radiotherapy by verifying that all personnel involved are appropriately trained for their duties, that the equipment used meets relevant international specifications for radiation safety and that safety culture is embedded in routine activities in radiotherapy departments. Many individuals must interact and work together on highly technical measurements and calculations, and therefore the potential for mistakes is great. A review of the mistakes shows that most are due to human error. The International Basic Safety Standards for Protection against Ionizing Radiation and the Safety of Radiation Sources (IAEA Safety Series No. 115) require that a prompt investigation be conducted whenever an accidental medical exposure of patients occurs. The report of the investigation is to be disseminated to the appropriate parties so that lessons can be learned to prevent similar accidents or mitigate their consequences in the future. This Safety Report is a collection of a large number of events that may serve as a checklist against which to test the vulnerability of a facility to potential accidents, and to provide a basis for improving safety in the use of radiation in medical applications. A further purpose of this report is to encourage readers to develop a questioning and learning attitude, adopt measures for the prevention of accidents, and prepare for mitigation of the consequences of accidents if they occur

    Planning and organisation, as well as actions taken during accidental discharging of hazardous substances (hydrocarbons) into the soil and water, show that without integrating all the functions of safety, occupational safety, fire and explosion protection, technical safety, all the way to the environmental protection, procedure of cleaning, rehabilitation and remediation of polluted areas into their original state cannot be successfully carried out. Neglecting any of the mentioned links/components of the procedure represents a risk to people's health and life, while pollution to the environment remains a constant threat. Development of technologies is quickly transforming the environment in which the professionals of all disciplines work. Therefore, the response to changes by application of new technologies and procedures in all domains is indispensable, however, through a comprehensive and expert perception and consideration of each of the essential correlations comprising the safety management in all the fields. Through management of safety projects in environmental protection, it has become obvious that a united management of different fields is necessary, as well as management of safety in general. Engineering, health, legislation, public, environmental standards, occupational safety, hazards, biophysical and socio-economic aspects are parts of an integral management. Experts joined efforts through interaction and communications are inter-disciplinary characteristics, i.e. multi-disciplinary safety management, but also the management of each project separately. Exactly this knowledge exchange is highly productive and becomes an indispensable element in recognition of indirect and cumulative actions, thus applicable in any field.

    Reports on accidental auto-injection of adrenaline are few. We encountered three cases of accidental injection of adrenaline. In this study, we have examined and reported the clinical courses and symptoms of our cases. CASE 1 involved a female physician in her 50s who had attended an explanatory meeting on auto-injection of adrenaline. She mistook EpiPen® to be the EpiPen trainer and accidentally injected herself with 0.3 mg EpiPen®. Her systolic/diastolic pressure peaked at 7 min to reach 144/78 mmHg and decreased to 120/77 mmHg at 14 min. Except for palpitation after 7 min, the only subjective symptom was local pain at the injection site. CASE 2 was noted in a 6-year-old boy. He accidentally pierced his right forefinger with 0.15 mg EpiPen®, and after 20 min, his right forefinger was swollen. The swelling improved 80 min after the accidental injection. CASE 3 was noted in a 4-year-old girl. She accidentally injected herself with 0.15 mg EpiPen®. Her systolic/diastolic pressure peaked at 23 min to reach 123/70 mmHg and decreased to 96/86 mmHg at 28 min. Severe adverse effects of accidental auto-injection of adrenaline were not observed in these three cases. Our findings suggest that while handling adrenaline auto-injectors, we should keep in mind the possibility of accidental injection.

    The Fukushima nuclear accident led to the most important accidental release of artificial radionuclides into the sea. This accident has underlined the importance of being able to adequately reproduce the fate of radioactive releases and to estimate their consequences for the marine environment. For its Crisis Centre, the French Institute for Radioprotection and Nuclear Safety (IRSN) has operational tools, in order to help experts and decision makers in case of any atmospheric accidental release and terrestrial environment contamination. The on-going project aims to develop tools to manage any marine contamination of the French coastal areas. We should be able to evaluate and anticipate the marine post-accidental situation: contaminated areas localization and contamination levels, and possible consequences. Many sites has be considered as potential source terms into the sea: the Coastal Nuclear Power Plants, the La Hague reprocessing Plant, the Brest and Toulon Military Harbours as home-ports of nuclear powered vessels, and different river mouths (Rhone River, Gironde, Loire, Seine) that could be contaminated by upstream accidental release. To achieve this goal, two complementary approaches are developed: Marine sheets and a dedicated modelling tool (STERNE). - Marine sheets aim to summarize marine environment characteristics for the different sites, identify potential stakes for human protection such as aquaculture areas, beaches, or industrial water intakes, and ecological stakes. Whenever possible, a local climatology (main currents depending on meteorological or tide conditions) that could be a support to first environmental measurement strategy is proposed. A list of available local contacts for any operational management is also provided. - The modelling tool, STERNE (Simulation du Transport et du transfert d'Elements Radioactifs dans l'environNEment marin), must predict radionuclide dispersion and contamination of water, marine species and sediments

  7. Cost of accidental carbon monoxide poisoning: A preventable expense.

    2016-06-01

    Carbon monoxide (CO) poisoning is common in the United States, accounting for hundreds of deaths and thousands of emergency department visits annually. It is believed that most accidental CO poisoning is preventable through public education, warning labels on consumer products, and uniform use of residential CO alarms. However, cost effectiveness of these prevention strategies has not been demonstrated in the United States to date. It was the objective of this study to estimate societal cost of accidental CO poisoning and evaluate the cost-effectiveness of universal installation of residential CO alarms. Published studies and data from the English language literature were used in to estimate direct hospital costs and lost earnings resulting from accidental CO poisoning. The study was performed in the US in 2015. Approximately 6600 individuals are estimated to sustain long-term cognitive sequela annually, with total loss in earnings of approximately $925 million, 334 individuals die from accidental, non-fire related CO poisoning with an average loss of 26 years of productivity accounting for $355 million, and 2800 are hospitalized with acute medical care costs of $33 million. Available data indicate that accidental CO poisoning in the US conservatively costs society over $1.3 billion, resulting from direct hospital costs and lost earnings. Further, it demonstrates a positive cost-benefit ratio for the uniform use of residential CO alarms.

    . The results proposed by ASTRAL can in turn be saved in its database, on the user's request, in order to be processed by other tools such as Geographical Information Systems, which enable spatial analysis and map production. Such maps are very helpful in crisis situations to decision makers since by answering to questions of a 'where?' type, at a given time, they complete the information delivered by ASTRAL, which answers to questions of a 'when?' type, at a given site. This is why a link to ASTRAL has been constructed in CARTINFO, an IRSN tool dedicated to mapping results for its Crisis Technical Center. Thus the CONRAD, ASTRAL and CARTINFO softwares constitute a chain for IRSN's Crisis Technical Center, calculating transfers through the environment and consequences of an atmospheric accidental radionuclide release. The development of this version started in 1999 and has been subject to a quality assurance program. The identified customers and users have been associated in a control committee expressing needs, validating choices and checking the good progress of the project. The programming is currently being validated by test scenarios that check the equations, parameters, functionalities and navigation through the screens. The technology and architecture chosen for the second version of ASTRAL are different from the previous ones. It now uses an internet technology and is of a three-third type, the software requiring an Oracle database, a Microsoft web server and a consultation station. These choices offer important advantages: the spreading and maintenance of the tool are very easy. In fact, once the server and the database have been installed an a network, the users only need a web browser to run the code. The initial installation and the updating are thus no more to be made an every user station, but only on the server and/or the database; the code may be installed on a portable computer, which hosts the database, the internet server and the web browser.

    The Gustave-Roussy Institute (I.G.R.), the biggest european center of cancer treatment, and the Institute of Protection and Nuclear Safety (I.P.S.N.) that lead important researches and expertise in accidental radiation protection have established an agreement for a research program for six years. The objective is to speed up the researches in radio-pathology and radiobiology to improve the techniques used to treat the irradiated persons, for therapeutic or accidental reasons. Three principal themes have been chosen as starting point: Diagnosis and prognosis bio-indicators of irradiation effects on the digestive system, biological dosimetry and long term effects of a high dose irradiation. New themes will be tackled in function of the results or new needs. (N.C.)

    This study has the aim to assess the impact of accidental release of radionuclides postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamic circulation and transport for the simulation of tritium dispersion caused by an accidental release in Ilha Grande Bay from the site of the future third plant in two circulation scenarios. The main difference between the scenarios is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1 x 10 9 to 5 x 10 5 Bq/m³ close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (< 11 kBq/m³). (author)

  14. Insurance of nuclear risk

    International Nuclear Information System (INIS)

    Lacroix, M.

    1976-01-01

    Insurance for large nuclear installations covers mainly four types of risk: third party liability which in accordance with the nuclear conventions, is borne by a nuclear operator following an incident occurring in his installation or during transport of nuclear substances; material damage to the installation itself, which precisely is not covered by third party liability insurance; machinery breakdown, i.e. accidental damage or interruption of operation. Only the first category must be insured. In view of the magnitude of the risk, nuclear insurance resorts to co-insurance and reinsurance techniques which results in a special organisation of the nuclear insurance market, based on national nuclear insurance pools and on the Standing Committee on Atomic Risk of the European Insurance Committee. Conferences of the chairmen of nuclear insurance pools are convened regularly at a worldwide level. (NEA) [fr

    The estimated energy equivalent of Chernobyl explosion was the 1/150 th of the explosive energy equivalent of atomic bomb dropped on Hiroshima; while the devastation that could be caused by the world's stock pile of nuclear weapons, could be equivalent to 160 millions of Chernobyl-like incidents. As known, the number of nuclear weapons is over 50,000 and 2000 nuclear weapons are sufficient to destroy the world. The Three Mile Island and Chernobyl accidents have been blamed on human factors but also the human element, particularly in the form of psychological stresses on those operating the nuclear weapons, could accidentally bring the world to a nuclear catastrophe. This opinion is encouraged by the London's Sunday Times magazine which gave a graphic description of life inside a nuclear submarine. So, to speak of nuclear reactor accidents and not of nuclear weapons is false security. (author)

  16. Hombro doloroso e incapacidad temporal. El retorno al trabajo tras larga baja por hombro doloroso: causalidad del trabajo en el hombro doloroso

    Directory of Open Access Journals (Sweden)

    José Manuel Vicente Pardo

    Full Text Available Material y método: Se han revisado textos publicados en la reseña bibliográfica así como los documentos de consulta citados en la misma. Resumen: El hombro doloroso, considerando con tal denominación diversos procesos con una misma significación disfuncional, supone causa habitual de procesos de incapacidad médica prolongada, bien en procesos que alcanzan o se alargan más allá de los 365 días de baja (incapacidad temporal, bien en procesos que pasan a situación de incapacidad permanente. La valoración de la incapacidad temporal por este tipo de procesos precisa una cuidadosa evaluación como la que proponemos; considerando además la trascendencia de las actuaciones médico evaluadoras. El hombro doloroso es causa de absentismo laboral prolongado y por ello se precisa implantar medidas que, sin disminuir la protección de la salud laboral, contribuyan a la más pronta y completa recuperación de las limitaciones funcionales consecuencia de este tipo de enfermedad. El retorno al trabajo tras incapacidad por hombro doloroso debe tener una consideración preventiva implícita, además de la valoración de las restituciones de las capacidades laborales funcionales y su correlación con las que exige el trabajo. Dicho retorno laboral no es siempre fácil ni exento de discrepancias o controversias, pero debe ser facilitado. Por ello proponemos algunas medidas para que sea posible sin perjuicio de la salud del trabajador, o que le cause desprotección. La determinación de la contingencia laboral por hombro doloroso (bien accidente de trabajo o bien enfermedad profesional es extremadamente habitual y por ello su consideración exige el cumplimiento de los requisitos de causalidad y médico legales establecidos aquí expuestos.

    Thomassin, A.; Merle-Szeremeta, A.

    2002-01-01

    In the scope of its assignments in the field of nuclear risks, the French Institute for Radiation protection and Nuclear Safety (IRSN) develops tools to assess the impact of nuclear facilities on their environment and surrounding populations. The code ACCI38 XL 2 is a tool dedicated to the assessment of integrated concentrations in the environment and of dosimetric consequences on man, in case of accidental atmospheric releases of radionuclides (up to 170 radionuclides). This code is widely used by IRSN for studies on accidents, mainly for the analysis of regulatory documents from nuclear operators. The aim of this communication is to present the main features of the model used in the code ACCI38 XL 2, and to give details about the code. After a general presentation of the model, a detailed description of atmospheric dispersion, transfer in the environment and radiological impact is given. Then, some information on parameters and limitations of the model and the code are presented

    2008-12-01

    Full Text Available La destrucción completa de Varsovia no fue por bombardeo, sino tuvo lugar de una manera fría y sistemática, manzana por manzana, por orden de Hitler, como represalia tras la sublevación espontánea de los habitantes de la ciudad en el denominado Levantamiento de Varsovia. Su reconstrucción se llevó a cabo en diversos grados de fidelidad e interpretación y con opciones críticas respecto a la estratificación de los monumentos y de la ciudad a través de la historia, llegando incluso a elegir hasta dónde se querían retroceder las agujas del reloj en la intervención. Más allá de cualquier consideración, la reconstrucción de Varsovia constituye un ejemplo de la tenacidad de un pueblo por aferrarse a la identidad construida que encarna su ciudad.

El objetivo: acercarse a la historia transcurrida tras las cámaras de la historiografía político-social tradicionalmente encargada del sujeto en cuestión, la cual creo un acervo, pero también un objeto desde una mirada particular. Las fuentes: dos novelas, Compañeros de viaje (1991 de Luis Fayad y El dedo índice de Mao (1993 de Juan Diego Mejía. El ejercicio permitió aproximarse a la escena privada y domestica estudiantil, reflexionar sobre el vínculo de esta con la vida pública y social y sobre la injerencia de las razones afectivas en los motivos de la vinculación o la militancia, así como interpretar la manera como significaron y enfrentaron el mundo en que vivieron, a partir de indicios y datos tipificados encontrados en las novelas. Finalmente, el artículo es una forma de demostrar y corroborar la eficacia del uso de la novela como fuente, que parece depender más de las capacidades del investigador que de las cualidades del material.

    2013-03-01

    Full Text Available La comprensión del sistema fiscal en el Reino de Granada tras la conquista castellana ha estado lastrada en la historiografía española durante decenios por la particularidad granadina, que prima sobre todo la continuidad de tipos tributarios islámicos y el hecho, innegable, de que la mayor parte de los pecheros fuesen los musulmanes vencidos, antes y después de la conversión general. Este artículo reexamina las pruebas conocidas e incluye varios ejemplos desarrollados de la amplia documentación inédita conservada para plantear un modelo general. Subraya dos hechos esenciales. La continuidad en los sistemas tributarios de época musulmana y su adaptación al sistema castellano y la participación política y el consentimiento fiscal de la población vencida para construir un sistema fiscal estable a partir de la época de Carlos V. El proceso se desarrolló en medio de fuertes convulsiones que incluyen enormes pérdidas poblacionales, por la huida de los musulmanes granadinos, entre la época de la conquista y el segundo decenio del siglo XVI, y la conversión masiva y obligatoria de los vencidos al cristianismo entre 1499 y 1501.

    To test young children’s false belief theory of mind in a morally relevant context, two experiments were conducted. In Experiment 1, children (N = 162) at 3.5, 5.5, and 7.5 years of age were administered 3 tasks: prototypic moral transgression task, false belief theory of mind task (ToM), and an “accidental transgressor” task, which measured a morally relevant false belief theory of mind (MoToM). Children who did not pass false belief ToM were more likely to attribute negative intentions to an accidental transgressor than children who passed false belief ToM, and to use moral reasons when blaming the accidental transgressor. In Experiment 2, children (N = 46) who did not pass false belief ToM viewed it as more acceptable to punish the accidental transgressor than did participants who passed false belief ToM. Findings are discussed in light of research on the emergence of moral judgment and theory of mind. PMID:21377148

    1986-01-01

    The World Association of Veterinary Food Hygienists (WAVFH) held an international round table conference in Stockholm, Sweden, January 26-29, 1987. The topic of the conference was 'Accidental Radiation Contamination of Food of Animal Origin'. The agenda was divided into three major topic areas: 1. Ecological Science; 2. Veterinary Science - Live Animals; and 3. Veterinary Science - Food of Animal Origin. Experts and delegates from member countries presented papers, participated in discussions and workshops and produced a multidisciplinary report covering the topic areas. The recent accidental release of radioactive substances into the environment from the Chernobyl accident, demonstrated the need for veterinary, ecological, physical and medical sciences to be prepared to respond to an incident in order to protect the environment, food chain, other agricultural assets and humans from the adverse effects of radionuclides. Several presentations suggested that even with the best technologies, national and regional commitment, and relatively unrestricted resource levels, nuclear incidents can cross international boundaries and can contaminate the environment to the extent that the integrity of various food and water supplies can be at risk. Speakers and subsequent discussers tended to concentrate on the issues associated with lessening future environmental impacts if similar types of incidents should occur again

  14. Structural Integrity Assessment of VVER-1000 RPV under Accidental Cool down Transients

    International Nuclear Information System (INIS)

    2012-01-01

    Corrosion, Fatigue and Irradiation embrittlement are the major degradation mechanisms responsible for ageing of RPV (and its internals) of a Pressurized Water Reactor. While corrosion and fatigue can generate cracks, irradiation damage can lead to brittle fracture initiating from these cracks. Ageing in nuclear power plants needs to be managed so as to ensure that design functions remain available throughout the life of the plant. From safety perspective, this implies that ageing degradation of systems, structures and components important to safety remain within acceptable limits. Reactor Pressure Vessel has been identified as the highest priority key component in plant life management for Pressurized Water Reactors. Therefore special attention is required to ensure its structural integrity during its lifetime. In this paper, structural integrity assessment for typical VVER-1000 RPV is carried out under severe accidental cool down transients using the Finite Element Method. Three different accidental scenarios are postulated and safety of the vessel is conservatively assessed under these transients using the Linear Elastic Fracture Mechanics approach. Transient thermo mechanical stress analysis of the core belt region of the RPV is carried out in presence of postulated cracks and stress intensity factors are calculated and compared with the material fracture toughness to assess the structural integrity of the vessel. The paper also include some parametric analyses to justify the methodology. (author)

  16. Methodology for evaluation of possible consequences of accidental atmospheric releases of hazardous matter

    International Nuclear Information System (INIS)

    Mahura, A.; Baklanov, A.; Havskov Sorensen, J.

    2003-01-01

    Sites exist with high levels of risk of accidental atmospheric releases. These releases can be hazardous nuclear, chemical, and biological matter. Such accidents may occur during transport of waste, or they may be due to natural hazards, human errors, terror acts or various operations at high risk. Considering the operation of lifting and transport of the sunken Kursk nuclear submarine as an example, a methodology for risk assessment is described. This methodology includes two approaches: (1) probabilistic analysis of possible atmospheric transport pathways using trajectory modelling, and (2) evaluation of possible contamination and consequences using real-time operational atmospheric dispersion modelling. The first approach can be applied in advance of an operation during the preparation stage, the second in real time during the operation stage. For the cases considered in this study, the results of trajectory modelling are supported by the operational dispersion modelling, i.e., the westerly flow is dominant during fall occurring 79% of the time. Hence, September-October 2001 was more appropriate for the lifting and transport of the Kursk nuclear submarine in comparison with summer months, when atmospheric transport toward the populated regions of the Kola and Scandinavian Peninsulas was dominant. The suggested methodology may be applied to any potentially dangerous object involving a risk of atmospheric release of hazardous material of nuclear, chemical or biological nature. (author)

  20. Nuclear insurance fire risk

    International Nuclear Information System (INIS)

    Dressler, E.G.

    2001-01-01

    Nuclear facilities operate under the constant risk that radioactive materials could be accidentally released off-site and cause injuries to people or damages to the property of others. Management of this nuclear risk, therefore, is very important to nuclear operators, financial stakeholders and the general public. Operators of these facilities normally retain a portion of this risk and transfer the remainder to others through an insurance mechanism. Since the nuclear loss exposure could be very high, insurers usually assess their risk first-hand by sending insurance engineers to conduct a nuclear insurance inspection. Because a serious fire can greatly increase the probability of an off-site release of radiation, fire safety should be included in the nuclear insurance inspection. This paper reviews essential elements of a facility's fire safety program as a key factor in underwriting nuclear third-party liability insurance. (author)

  1. NRC's rulemaking to require materials licensees to be financially responsible for cleanup of accidental releases

    International Nuclear Information System (INIS)

    Seeman, M.J.

    1987-01-01

    On June 7, 1985, the US Nuclear Regulatory Commission (NRC) published an advance notice of proposed rulemaking (ANPRM) in the Federal Register to address funding for cleanup of accidents and unexpected decontamination by certain materials licensees. The NRC asked for public comment to help them determine whether to amend its regulations to require certain materials and fuel cycle licensees to demonstrate that they possess adequate financial means to pay for cleanup of accidental releases of radioactive materials. If licensees lack adequate financial resources and funds are to available for prompt cleanup, the consequences could be potentially significant for the public, the licencee and the federal government. The purpose of this paper is to explain the purpose and scope of the Commission's proposed regulatory action, as well as describing several accidents that made the Commission consider this action. Additionally, the paper will address other regulatory precedents. Finally, the paper will conclude by generally characterizing the public comments and items of concern raised by commenters

    1988-08-01

    Of the more than 450 underground nuclear explosives tests conducted at the Nevada Test Site from August 1963 (signing of the Limited Test Ban Treaty) through the end of 1986, only 23 accidentally released radioactivity that was detectable beyond the boundary of the NTS. Of these 23, 4 were detectable off the NTS only by aircraft while the remainder were detectable by ground monitoring instruments. Since the Baneberry venting of December 1970, only two tests released radioactivity that was detectable off the NTS, and this was a seepage of radioactive noble gases. None of these releases from underground tests designed for complete containment caused exposure of the population living in the area that exceeded standards recommended by national and international radiation protection agencies. This report summarizes the releases from each of the tests, describes the monitoring that was conducted, and lists the location of the maximum exposure

    The objective of the study was comparison of the doses received due to contamination of the Techa River with those received from the indoor radon exposure. The study was performed on the example of Muslyumovo, the village closest to Mayak nuclear complex. The accidental doses were estimated using data on radionuclide intakes and ICRP-72 dose coefficients, and Techa River Dosimetry System. Radon exposure was estimated applying results of the radon surveys in 1992 and 2015. The doses prevented by means of different protection measures were considered. The maximum reduction of population exposure could be achieved in the case of timely evacuation to uncontaminated territory together with the indoor radon prevention measures. © The Author 2017.

  5. Modelling for radiological and radioecological consequences of an accidental radionuclide release at Sea

    1997-01-01

    Full text: Scenarios concerning accidental releases of radionuclides into water bodies can be found in the open literature, mostly in connection with nuclear power plants located either onshore or inland. However, meager attention has been given to nuclear reactors used as energy sources for propulsion at sea, which are also subject to accidents. Such potential accidents may involve the loss of part of the reactor core to the surrounding water body. In addition of the initial instantaneous releases, one can estimate delayed source terms based on the rate at which radionuclides are dissolved or leached from the solidified material, like part of the core or structural materials in contact with water. Most of such solidified material might be a mixture of uranium, zirconium, iron, calcium, silica, fission and activation products, and transuranium elements as oxides, forming a glassy type solid. Transport models were used to calculate radionuclide concentrations in water resulting from short and delayed source terms. Oceanographic data used in the calculations were taken either from the open literature or from unclassified reports of the Brazilian Navy, being, however, as generic as possible. Time-dependent concentration functions for radionuclides in aquatic food following an accidental release reflect the net result of intake and elimination processes. However, to avoid the complexities of multiple parameters involved in such processes, the model accounts only for trophic transfer of radionuclides, and yet avoids the necessity of analyzing the details of each transfer step used to determine fish, crustacea, molluscs and seaweed accumulation. Swimming and other aquatic sports are not included in the model used for dose calculations because of theirs relatively low importance in comparison with the pathways concerning ingestion of aquatic food

    Toothbrush is a rare foreign body to be ingested accidentally. The unusual shape of the toothbrush with no theoretical possibility of spontaneous passage mandates an interventional approach. If left untreated, it can lead to pressure necrosis, bleeding, perforation and ulceration. An endoscopic attempt in an expert clinic if available is the ideal approach. If failed, surgical management by laparoscope or mini laparotomy should be done. The evaluation for underlying psychiatric disorders like bulimia, schizophrenia or generalized eating disorder should be considered to prevent such recurrence. Here, we present a case of 55 years of age, male living a normal life with no known comorbid, who ingested accidentally a toothbrush two weeks prior to presentation and was managed at our surgical department after a failed endoscopic attempt.

  7. Accidental degeneracy of double Dirac cones in a phononic crystal

    Chen, Ze-Guo

    2014-04-09

    Artificial honeycomb lattices with Dirac cone dispersion provide a macroscopic platform to study the massless Dirac quasiparticles and their novel geometric phases. In this paper, a quadruple-degenerate state is achieved at the center of the Brillouin zone in a two-dimensional honeycomb lattice phononic crystal, which is a result of accidental degeneracy of two double-degenerate states. In the vicinity of the quadruple-degenerate state, the dispersion relation is linear. Such quadruple degeneracy is analyzed by rigorous representation theory of groups. Using method, a reduced Hamiltonian is obtained to describe the linear Dirac dispersion relations of this quadruple-degenerate state, which is well consistent with the simulation results. Near such accidental degeneracy, we observe some unique properties in wave propagating, such as defect-insensitive propagating character and the Talbot effect.

  8. Leading global projects for professional and accidental project leaders

    Moran, Robert T

    2008-01-01

    This book is a must-read for anyone responsible for projects and initiatives that span functional and geographical divides. Authors Moran and Youngdahl bring extensive experience and learning from industry practice to present a clear and straightforward treatment of the leadership skills and knowledge required to lead projects that are global in nature. They have written the first book of its kind to address the three essential skills of global project leaders - strategic project management, project leadership, and cross-cultural leadership. The authors argue that global project leadership is an essential skill in our project-based world and that we are all either intentional or accidental project leaders. Intentional project leaders pursue formal project management education and even certification whereas accidental project leaders find themselves leading global projects and initiatives as a result of a special assignment or promotion. Moran and Youndahl have found that the vast majority of global projects ...

  9. La prevención de accidentes (3

    Full Text Available The financial loss due to working accidents is very substantial, quite apart from the actual loss of human lives. Hence avoiding these accidents is a most important matter. The accident index in the various industries shows a rate of increase that is larger than should be the case in proportion to the development of the industries concerned, and the larger number of employees. The fact that these indexes are smaller in many countries, however, shows that these accidents can be considerably reduced if suitable measures are taken to avoid them. In chapter 2 of our magazine, issue no. 178, a variety of reasons were discussed that may originate accidents, although these causes are not directly linked to the accident itself. In this article mention is made of some of the measures that can be taken in the handling of cutting and welding equipment, and also of inflammable liquids, to prevent possible accidents.El peso de los accidentes de trabajo sobre la economía supone cantidades muy grandes que, independientemente del inestimable valor de una vida humana, realzan la importancia de la prevención de accidentes. Los índices de accidentes muestran en diferentes industrias un crecimiento mayor de lo que debería corresponder proporcionalmente, habida cuenta del crecimiento laboral. El hecho de que en distintos países los índices sean inferiores, demuestra que se pueden conseguir buenos frutos si se concede primordial importancia a que los trabajos se realicen con las debidas medidas de seguridad. En el Capítulo 2, número 178 de esta Revista, se detallaron diversas causas que pueden originar un accidente sin estar ligadas en forma directa con una tarea determinada. En el presente trabajo se indican algunas de las medidas que deben observarse en el manejo de los equipos de soldadura y corte, así como en el transvase de líquidos inflamables.

    2010-01-01

    Our objective was to conduct a pilot study to identify discriminating bruising characteristics and to model those findings into a decision tool for screening children at high risk for abuse. A case-control study of children 0 to 48 months of age who were admitted to a PICU because of trauma was performed. Case subjects (N = 42) were victims of physical abuse, and control subjects (N = 53) were children admitted because of accidental trauma during the same time period. Bruising characteristics (total number and body region) and patient age were compared for children with abusive versus accidental trauma. The development of a decision rule for predicting abusive trauma was accomplished with the fitting of a classification and regression tree through binary recursive partitioning. Ninety-five patients were studied. Seventy-one (33 of 42 patients in the abuse group and 38 of 53 in the accident group) were found to have bruising, and the characteristics were modeled. Characteristics predictive of abuse were bruising on the torso, ear, or neck for a child abuse. Discriminating differences exist in bruising characteristics for abusive versus accidental trauma. The body region- and age-based bruising clinical decision rule model functions as a clinically sensible screening tool to identify young children who require further evaluation for abuse.

    The application of lamp phosphors for accidental dosimetry is a new concept. Since the materials used in fluorescent lamps are good photo luminescent materials, if one can either use the inherent defects present in the phosphor or add suitable modifiers to induce thermoluminescence (TL) in these phosphors, then the device (fluorescent lamp) can be used as an accidental dosemeter. In continuation of our search for a suitable phosphor material, which can serve both as an efficient lamp phosphor and as a good radiation monitoring device, detailed examination has been carried out on cerium and terbium-doped lanthanum phosphate material. A 90 Sr beta source with 50 mCi strength (1.85 GBq) was used as the irradiation source for TL studies. The TL response as a function of dose received was examined for all phosphors used and it was observed that the intensity of the TL peak vs. dose received was a linear function in the dose range 0.1-200 Gy in each case. Incidentally LaPO 4 :Ce,Tb is a component of the compact fluorescent lamp marketed recently as an energy bright light source. Besides having very good luminescence efficiency, good dosimetric properties of these phosphors render them useful for their use in accidental dosimetry also. (authors)

    Knowledge and lessons from past accidental exposures in radiotherapy are very helpful in finding safety provisions to prevent recurrence. Disseminating lessons is necessary but not sufficient. There may be additional latent risks for other accidental exposures, which have not been reported or have not occurred, but are possible and may occur in the future if not identified, analyzed, and prevented by safety provisions. Proactive methods are available for anticipating and quantifying risk from potential event sequences. In this work, proactive methods, successfully used in industry, have been adapted and used in radiotherapy. Risk matrix is a tool that can be used in individual hospitals to classify event sequences in levels of risk. As with any anticipative method, the risk matrix involves a systematic search for potential risks; that is, any situation that can cause an accidental exposure. The method contributes new insights: The application of the risk matrix approach has identified that another group of less catastrophic but still severe single-patient events may have a higher probability, resulting in higher risk. The use of the risk matrix approach for safety assessment in individual hospitals would provide an opportunity for self-evaluation and managing the safety measures that are most suitable to the hospital's own conditions.

  16. Accidental introductions are an important source of invasive plants in the continental United States.

    2013-07-01

    Preventing new plant invasions is critical for reducing large-scale ecological change. Most studies have focused on the deliberate introduction of nonnatives via the ornamental plant trade. However, accidental introduction may be an important source of nonnative, invasive plants. Using Web and literature searches, we compiled pathways of introduction to the United States for 1112 nonnative plants identified as invasive in the continental United States. We assessed how the proportion of accidentally and deliberately introduced invasive plants varies over time and space and by growth habit across the lower 48 states. Deliberate introductions of ornamentals are the primary source of invasive plants in the United States, but accidental introductions through seed contaminants are an important secondary source. Invasive forbs and grasses are the most likely to have arrived accidentally through seed contaminants, while almost all nonnative, invasive trees were introduced deliberately. Nonnative plants invading eastern states primarily arrived deliberately as ornamentals, while a high proportion of invasive plants in western states arrived accidentally as seed contaminants. Accidental introductions may be increasing in importance through time. Before 1850, 10 of 89 (11%) of invasive plants arrived accidentally. After 1900, 20 of 65 (31%) arrived accidentally. Recently enacted screening protocols and weed risk assessments aim to reduce the number of potentially invasive species arriving to the United States via deliberate introduction pathways. Increasing proportions of accidentally introduced invasive plants, particularly associated with contaminated seed imports across the western states, suggest that accidental introduction pathways also need to be considered in future regulatory decisions.

    2015-12-01

    Although non-accidental injuries (NAI) are more common in cases of unexplained fractures than rare disorders such as osteogenesis imperfecta (OI), ruling out OI and other medical causes of fracture is always indicated. The majority of OI patients can be diagnosed with the help of family history, physical examination, and radiographic findings. In particular, there are a few radiological findings which are seen more commonly in NAI than in OI which may help guide clinician considerations regarding the probability of either of these diagnoses. At the same time, molecular testing still merits careful consideration in cases with unexplained fractures without obvious additional signs of abuse. © 2015 Wiley Periodicals, Inc.

    1980-04-01

    An improvement in a tritium control system based on a catalytic oxidation reactor wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release.

    2014-01-01

    Full Text Available Excessive ethanol consumption is a leading preventable cause of death in the United States. Much of the harm from ethanol comes from those who engage in excessive or hazardous drinking. Rectal absorption of ethanol bypasses the first pass metabolic effect, allowing for a higher concentration of blood ethanol to occur for a given volume of solution and, consequently, greater potential for central nervous system depression. However, accidental death is extremely rare with rectal administration. This case report describes an individual with klismaphilia whose death resulted from acute ethanol intoxication by rectal absorption of a wine enema.

    Daburon, F.; Vincent-Naulleau, S.

    2001-01-01

    When a serious nuclear accident occurs, the radioisotopes of caesium are very worrying to public health. Because of their long environmental persistence, their diffusion and their solubility in natural environments, they are present in many foodstuffs. Numerous studies were undertaken during the atmospheric nuclear tests, but since the accident of Tchernobyl land Goiania, this research has been pursued anew. By using the experimental data,, this report takes stock of the knowledge on the metabolic transit of radiocaesium in domestic animals. The transfer of this radionuclide in the major foodstuffs of animal origin (milk, meat, eggs) is important and depends on the metabolism of the animal species, and in one species, the age, the physiologic state and the diet. Nevertheless, it is possible to restrict the radioactive contamination by adding to all animal feed, some additives. The methods for in vivo determination of the radioactive measurements in cattle, in laboratory or in real conditions, are discussed too. Finally, all these results are used to consider the short-, middle- and long-term management of an accidental situation. (authors)

    Aging of the patient population has led to increased occurrence of accidental falls in acute care settings. The aim of this study is to survey the annual occurrence of falls in a university hospital, and to examine procedures to prevent fall. A total of 49,059 inpatients were admitted to our hospital from April 2015 to March 2016. A fall assessment scale was developed to estimate the risk of fall at admission. Data on falls were obtained from the hospital incident reporting system. There were fall-related incidents in 826 patients (1.7%). Most falls occurred in hospital rooms (67%). Adverse events occurred in 101 patients who fell (12%) and were significantly more frequent in patients aged ≥80 years old and in those wearing slippers. The incidence of falls was also significantly higher in patients in the highest risk group. These results support the validity of the risk assessment scale for predicting accidental falls in an acute treatment setting. The findings also clarify the demographic and environmental factors and consequences associated with fall. These results of the study could provide important information for designing effective interventions to prevent fall in elderly patients.

    Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

    Bolt gun or slaughterer's guns are used in meat industry for "humane killing" of animals. Injuries caused by bolt gun are rare, reported exclusively from central European countries. We report a case of 28 year old male, who accidentally shot himself with a bolt gun to his right thigh. A 28 years old male presented to our Accident and Emergency department after accidental injury to his right thigh with bolt gun. He had an entry wound measuring 2 cm in length and 1 cm in breadth over anterior aspect of lower one third of thigh at lower and sustained Grade II compound fracture of right femur shaft at distal one third. The wound was treated with multiple debridements, negative pressure wound therapy and intravenous antibiotics based on culture and sensitivity. Bolt gun or slaughterer's guns are weapons used in meat industry for slaughtering animals. Wounds inflicted by bolt guns have specific morphological feature, distinctive from wounds made by other kinds of hand firearms. Most of the time wound will be infected at presentation. Lesions caused by these weapons are likely to have a more serious character than is to be expected from the size of the entrance wound. The mainstay of treatment is liberal wound exploration, multiple debridement's and intra venous antibiotics based on culture reports to treat infection and prevent morbidity.

    Compressed air is being used extensively as a source of energy at industries and in daily life. A variety of fatal injuries are caused by improper and ignorant use of compressed air equipments. Many types of injuries due to compressed air are reported in the literature such as colorectal injury, orbital injury, surgical emphysema, and so on. Most of these injuries are accidental in nature. It is documented that 40 pounds per square inch pressure causes fatal injuries to the ear, eyes, lungs, stomach, and intestine. Openings of body are vulnerable to injuries by compressed air. Death due to compressed air injuries is rarely reported. Many cases are treated successfully by conservative or surgical management. Extensive survey of literature revealed no reports of fatal injury to the upper respiratory tract and lungs caused by compressed air. Here, we are reporting a fatal event of accidental death after insertion of compressed air pipe into the mouth. The postmortem findings are corroborated with the history and discussed in detail.

    Accidental death from postural or positional asphyxia takes place when the abnormal position of the victim's body compromises the process of respiration. Diagnosis is largely made by circumstantial evidence supported by absence of any other significant pathology or trauma explaining death. This case report is about a 50-year-old male who had been drinking the previous night and was found dead in the morning inside a tire repair shop. His jack-knifed body had been encompassed, buttocks-down, within the hollow core made by 3 big tires stacked on top of each other. The author was called to the scene of death and had hands-on encounter with the body in-situ where scene photographs were taken. Apart from a blood alcohol of 290 mg/100 ml, marked congestion of the face, petechial hemorrhages on the conjunctivae and lung edema and congestion, autopsy findings were unremarkable. Abrasions on shoulders, lateral aspects of arms and posterior aspects of lower legs indicated friction with internal rims of tires while slipping down. There were no other injuries or pathology to account for his death. Death was determined to be due to accidental postural asphyxia secondary to intoxication by alcohol.

    Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs). Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004-2012 due to poisoning with paracetamol. The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004-2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose. During the period of the study, 44 patients aged 2.1-17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2%) cases of intentional poisonings, 10 (22.7%) of accidental poisonings, and only 4 patients (9.1%) were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%). Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever. Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

    Full Text Available Abstract Background The ends of chromosomes, termed telomeres consist of repetitive DNA. The telomeric sequences shorten with cell division and, when telomeres are critically abbreviated, cells stop proliferating. However, in cancer cells, by the expression of telomerase which elongates telomeres, the cells can continue proliferating. Many approaches for telomere shortening have been pursued in the past, but to our knowledge, cutting telomeres in vivo has not so far been demonstrated. In addition, there is lack of information on the cellular effects of telomere shortening in human cells. Results Here, we created novel chimeric endonucleases to cut telomeres by fusing the endonuclease domain (TRAS1EN of the silkworm's telomere specific non-long terminal repeat retrotransposon TRAS1 to the human telomere-binding protein, TRF1. An in vitro assay demonstrated that the TRAS1EN-TRF1 chimeric endonucleases (T-EN and EN-T cut the human (TTAGGGn repeats specifically. The concentration of TRAS1EN-TRF1 chimeric endonucleases necessary for the cleavage of (TTAGGGn repeats was about 40-fold lower than that of TRAS1EN alone. When TRAS1EN-TRF1 endonucleases were introduced into human U2OS cancer cells using adenovirus vectors, the enzymes localized at telomeres of nuclei, cleaved and shortened the telomeric DNA by double-strand breaks. When human U2OS and HFL-1 fibroblast cells were infected with EN-T recombinant adenovirus, their cellular proliferation was suppressed for about 2 weeks after infection. In contrast, the TRAS1EN mutant (H258A chimeric endonuclease fused with TRF1 (ENmut-T did not show the suppression effect. The EN-T recombinant adenovirus induced telomere shortening in U2OS cells, activated the p53-dependent pathway and caused the senescence associated cellular responses, while the ENmut-T construct did not show such effects. Conclusions A novel TRAS1EN-TRF1 chimeric endonuclease (EN-T cuts the human telomeric repeats (TTAGGGn specifically in

    In this work was carried out the analysis of two scenarios of the accident type with loss of coolant in a recirculation loop for a break with smaller ares to 0.1 ft{sup 2} (4.6 cm{sup 2}), which is classified according to their size like small Loca. The first simulated scenario was a small Loca without action of the emergency coolant injection systems, and the second was a small Loca with only the available system LPCS. This design base accident was taken into account for its relevance with regard to the damage to the core and the hydrogen generation. Was also observed and analyzed the response of the action of the ECCS that depend of the loss of coolant reason and this in turn depends of the size and type of the pipe break. The specified scenarios were simulated by means of the use of MELCOR model for the nuclear power plant of Laguna Verde that has the Comision Nacional de Seguridad Nuclear y Salvaguardias. (Author)

    The Fukushima nuclear accident resulted in the largest ever accidental release of artificial radionuclides in coastal waters. This accident has shown the importance of marine assessment capabilities for emergency response and the need to develop tools for adequately predicting the evolution and potential impact of radioactive releases to the marine environment. The French Institute for Radiological Protection and Nuclear Safety (IRSN) equips its emergency response centre with operational tools to assist experts and decision makers in the event of accidental atmospheric releases and contamination of the terrestrial environment. The on-going project aims to develop tools for the management of marine contamination events in French coastal areas. This should allow us to evaluate and anticipate post-accident conditions, including potential contamination sites, contamination levels and potential consequences. In order to achieve this goal, two complementary tools are developed: site-specific marine data sheets and a dedicated simulation tool (STERNE, Simulation du Transport et du transfert d'Eléments Radioactifs dans l'environNEment marin). Marine data sheets are used to summarize the marine environment characteristics of the various sites considered, and to identify vulnerable areas requiring implementation of population protection measures, such as aquaculture areas, beaches or industrial water intakes, as well as areas of major ecological interest. Local climatological data (dominant sea currents as a function of meteorological or tidal conditions) serving as the basis for an initial environmental sampling strategy is provided whenever possible, along with a list of possible local contacts for operational management purposes. The STERNE simulation tool is designed to predict radionuclide dispersion and contamination in seawater and marine species by incorporating spatio-temporal data. 3D hydrodynamic forecasts are used as input data.

    The Health and Safety Executive (HSE) has requested Sandia National Laboratories (SNL) to review the aircraft crash methodology for nuclear facilities that are being used in the United Kingdom (UK). The scope of the work included a review of one method utilized in the UK for assessing the potential for accidental airplane crashes into nuclear facilities (Task 1) and a comparison of the UK methodology against similar International Atomic Energy Agency (IAEA), United States (US) Department of Energy (DOE), and the US Nuclear Regulatory Commission (NRC) methods (Task 2). Based on the conclusions from Tasks 1 and 2, an additional Task 3 would provide an assessment of a site-specific crash frequency for the Dungeness B facility using one of the other methodologies. This report documents the results of Task 2. The comparison of the different methods was performed for the three primary contributors to aircraft crash risk at the Dungeness B site: airfield related crashes, crashes below airways, and background crashes. The methods and data specified in each methodology were compared for each of these risk contributors, differences in the methodologies were identified, and the importance of these differences was qualitatively and quantitatively assessed. The bases for each of the methods and the data used were considered in this assessment process. A comparison of the treatment of the consequences of the aircraft crashes was not included in this assessment because the frequency of crashes into critical structures is currently low based on the existing Dungeness B assessment. Although the comparison found substantial differences between the UK and the three alternative methodologies (IAEA, NRC, and DOE) this assessment concludes that use of any of these alternative methodologies would not change the conclusions reached for the Dungeness B site. Performance of Task 3 is thus not recommended.

    AIM: To evaluate the type and nature of head injuries sustained by children under the age of 5 years who present to a busy accident and emergency (A and E) department following an accidental fall. MATERIALS AND METHODS: This study included all children under the age of 5 years, who over an 8-month period were referred to our A and E Department with head injury following an accidental fall. Data were collected regarding the height of the fall, whether or not stairs were involved, the type of surface that the child landed on and the height of the child. This was correlated with any soft-tissue injury or skull fracture. RESULTS: A total of 72 children (aged 4 months to 4.75 years) fulfilled all the criteria for an accidental fall. The heights of the falls ranged from less than 50 cm to over 3 m, with the majority below 1 m. Of the falls, 49 were onto a hard surface and 23 were onto a soft surface. Of the 72 children, 52 had visible evidence of head injury, 35 (71%) of 49 being the result of falls onto hard surfaces and 17 (74%) of 23 onto soft (carpeted) surfaces. There was no significant difference in the type of surface that resulted in a visible head injury. A visible head injury was seen in all children who fell from a height of over 1.5 m and in 95% of children who fell over 1 m. Of the 72 children, 32 (44%) had skull radiographs performed in accordance with established guidelines and 4 (12.5%) were identified as having a fracture. Of the 3 linear parietal fractures 2 were inflicted by falls of just over 1 m (from a work surface) and 1 by a fall of 80 to 90 cm onto the hard-edged surface of a stone fire surround. The 4th was a fracture of the base of skull following a fall from more than 3 m (from a first-storey window). CONCLUSIONS: In the vast majority of domestic accidents children do not suffer significant harm. Skull fractures are rare and probably occur in less than 5% of cases. To cause a skull fracture the fall needs to be from over 1 m or, if from a

    The case is described of accidental irradiation of a male person with /sup 137/Cs of an activity of 24.71 GBq. The first estimate induced a reasonable suspicion that the absorbed dose could be very high and life-threatening. On the other hand the clinical picture, usual laboratory examinations, findings in the fluorescent blood count, the analysis of chromosomal count of lymphocytes in the peripheral blood, the spermiogram, and the negative post-irradiation porphyrinuria suggested that the absorbed dose could be much lower than the original estimate. The results of dosimetry obtained after the reconstruction of the accident by measuring on a phantom revealed that the actual dose was very close to that presumed from the results of biological dosimetry during the first days of examination of the patient.

    Identity cards designed to provide high security against falsification are often composed of polymeric compounds and a paper-like inlay containing the identifying information. This system may be considered as a fast neutron detector when certain boundary conditions, especially concerning the polymer are fulfilled. The track recording properties of the plastic envelope of a widely used identity card were investigated. Recoil tracks induced by fast neutrons were revealed by electrochemical etching in 5N NaOH in a thin cover mounted on a trick etch-resistant base. The etching parameters (etchant normality, temperature, time, field strength, frequency) were optimized to achieve maximum neutron sensitivity. The response for neutrons from a CF 252 source is about one per cent of that of the widely used CR-39 track detector material. The possible use of the identity card as an etch track detector in accidental neutron dosimetry is discussed. (author)

    Full Text Available The study presented in this article describes a modern modeling methodology of the propagation of accidental flood waves in case a dam break; this methodology is applied in Romania for the first time for the pilot project „Breaking scenarios of Poiana Uzului dam”. The calculation programs used help us obtain a bidimensional calculation (2D of the propagation of flood waves, taking into consideration the diminishing of the flood wave on a normal direction to the main direction; this diminishing of the flood wave is important in the case of sinuous courses of water or with urban settlements very close to the minor river bed. In the case of Poiana Uzului dam, 2 scenarios were simulated with the help of Ph.D. Eng. Dan Stematiu, plausible scenarios but with very little chances of actually producing. The results were presented as animations with flooded surfaces at certain time steps successively.

    In the present paper we present the consequences of an accidental occupational radiation exposure at a local hospital in Buenos Aires. Control at a local radiology service showed the lack of correct shielding in the X-ray equipment. The physicians and technicians (14 persons) exposed to radiation during 12 months were examined. The survey shows that: a) In 11 out of 14 radiation-exposed patients nodular goiter developed and an additional patient had diffuse goiter which means a goiter incidence of 85.7%; b) In 5 of the nodular goiter patients an increase in the size or the appearance of new nodules was observed along the follow-up period. No cancer was detected by FNA; c) Hypothyroidism was observed in 3/14 patients, and an additional patient had an abnormal TRH-TSH test, suggesting subclinical hypothyroidism; and d) Increased circulating antithyroid antibodies were found in one of the hypothyroid patients

    2016-02-22

    In this paper we present a general method for estimating rates of accidental coincidence between a pair of single photon detectors operated within their saturation regimes. By folding the effects of recovery time of both detectors and the detection circuit into an "effective duty cycle" we are able to accomodate complex recovery behaviour at high event rates. As an example, we provide a detailed high-level model for the behaviour of passively quenched avalanche photodiodes, and demonstrate effective background subtraction at rates commonly associated with detector saturation. We show that by post-processing using the updated model, we observe an improvement in polarization correlation visibility from 88.7% to 96.9% in our experimental dataset. This technique will be useful in improving the signal-to-noise ratio in applications which depend on coincidence measurements, especially in situations where rapid changes in flux may cause detector saturation.

Both plants grow on damp meadows and can be easily wrongly identified especially before blooming period as they have similar, pointed leaves.Results. Considering anamnestic data, clinical picture and laboratory findings in 43-yr-old female, a poisoning with the colchicine plant alkaloid was suspected. Later, it was confirmed by toxicology analyses (chromatography and spectrometry of the collected serum and urine samples. Severe initial gastrointestinal disorders progressed into ileus, bone-marrow suppression and multi-organ failure.Conclusions. After the patient had received a symptomatic treatment with granulocyte-directed growth factor and a suitable antibiotic therapy for secondary infection, she recovered within three weeks from the onset of condition. The most persistent problem was alopecia. The disease did not entailed any permanent sequellae which was confirmed 3 years after the patient was considered cured.

    The investigation of uncertain fatalities requires accurate determination of the cause of death, with assessment of all factors that may have contributed to it. Gasoline is a complex and highly variable mixture of aliphatic and aromatic hydrocarbons that can lead to cardiac arrhythmias due to sensitization of the myocardium to catecholamines or acts as a simple asphyxiant if the vapors displace sufficient oxygen from the breathing atmosphere. This work describes a sudden occupational fatality involving gasoline. The importance of this petroleum distillate detection and its quantitative toxicological significance is discussed using a validated analytical method. A 51 year-old Caucasian healthy man without significant medical history was supervising the repairs of the telephone lines in a manhole near to a gas station. He died suddenly after inhaling gasoline vapors from an accidental leak. Extensive blistering and peeling of skin were observed on the skin of the face, neck, anterior chest, upper and lower extremities, and back. The internal examination showed a strong odor of gasoline, specially detected in the respiratory tract. The toxicological screening and quantitation of gasoline was performed by means of gas chromatography with flame ionization detector and confirmation was performed using gas chromatography-mass spectrometry. Disposition of gasoline in different tissues was as follows: heart blood, 35.7 mg/L; urine, not detected; vitreous humor, 1.9 mg/L; liver, 194.7 mg/kg; lung, 147.6 mg/kg; and gastric content, 116,6 mg/L (2.7 mg total). Based upon the toxicological data along with the autopsy findings, the cause of death was determined to be gasoline poisoning and the manner of death was accidental. We would like to alert on the importance of testing for gasoline, and in general for volatile hydrocarbons, in work-related sudden deaths involving inhalation of hydrocarbon vapors and/or exhaust fumes.

    Accidental ingestion of foreign bodies is a common pediatric problem. Non-sharp items like coins, jewelry, pieces of toys are most frequently found among swallowed objects. They usually pass through a child's digestive system without health consequences (40-90% of reported cases). Approximately 10% of children require endoscopic intervention and 1-3% undergoes a surgical treatment. Authors present a unique health hazard caused by multiple magnet ingestion and general management in these cases of this specific foreign body presence. A 6 y.o. boy, in excellent health has been admitted G.I. Dept. presenting a history of accidental ingestion of two magnets (size 1.5 x 0.5 cm) 4 days prior to hospitalization. On admission patient presented no symptoms of foreign body in GI tract, however his WBC was 15000/mm3, ESR-22mm. Foreign bodies have been removed under general anesthesia using endoscopic technique. Endoscopic view of the esophagus region from which magnet has been removed at first might have been identify as a perforation of the esophageal wall. Chest X-ray has not revealed symptoms of pneumothorax, as well as the contrast radiologic study showed symptoms of upper GI tract perforation. Conservative treatment has been administered. Patient has been discharged home with no complaints in general and local good condition. Ingestion of more than one magnets is an strong indication for an immediate endoscopic intervention. Such an algorithm is strongly advocated to prevent of lesion formation in the soft tissues located between two objects with paramagnetic properties which may cause ischemic necrosis and perforation of the GI tract wall.

    Major nuclear accidents of Chernobyl (April, 1986) and Fukushima (March, 2011) have led to a huge environmental contamination with important amounts of radionuclides released in the atmosphere. Risk assessment, in case of nuclear emergency, is confronted to uncertainties on the transfer of radioactive substances in terrestrial ecosystems and to human population through the food chain, which could affect the reliability of decisions. The extent of the repercussions of Chernobyl and Fukushima accidents highlighted the difficulty of managing the consequences of such disasters and specifically to accommodate the different sources of uncertainty within decision-making processes. The objective of this research project is to develop a methodology to take into account uncertainties within environmental and food risk assessment models in order to improve decision support tools used for accidental situations. In this regard, different hierarchical Bayesian models aiming at capturing, within a unique modelling framework, uncertainty and variability about radioecological parameters of great important for accidental situation (dry and wet interception fractions and weathering loss parameter) were developed. Models parameters were estimated by Bayesian inference applied on databases obtained by an extended literature review. The impact on the risk assessment models of uncertainty and variability about these radioecological parameters was then assessed by stochastic simulations and sensitivity analyses applied on two case-studies: a hypothetical accident simulating a standardized deposition of radionuclides and the accident of Fukushima nuclear power plant. The works developed in this project contribute to enhance knowledge on key processes governing environmental transfer of radionuclides and to improve the parameterization of the radioecological risk assessment models with respect to the research lines outlined by the scientific community in radioecology.

    Full Text Available Purpose. To assess the frequency, risk factors, and management of accidental durotomy in minimally invasive transforaminal lumbar interbody fusion (MIS TLIF. Methods. This single-center study retrospectively investigates 372 patients who underwent MIS TLIF and were mobilized within 24 hours after surgery. The frequency of accidental durotomies, intraoperative closure technique, body mass index, and history of previous surgery was recorded. Results. We identified 32 accidental durotomies in 514 MIS TLIF levels (6.2%. Analysis showed a statistically significant relation of accidental durotomies to overweight patients (body mass index ≥25 kg/m2; P=0.0493. Patient age older than 65 years tended to be a positive predictor for accidental durotomies (P=0.0657. Mobilizing patients on the first postoperative day, we observed no durotomy-associated complications. Conclusions. The frequency of accidental durotomies in MIS TLIF is low, with overweight being a risk factor for accidental durotomies. The minimally invasive approach seems to minimize durotomy-associated complications (CSF leakage, pseudomeningocele because of the limited dead space in the soft tissue. Patients with accidental durotomy can usually be mobilized within 24 hours after MIS TLIF without increased risk. The minimally invasive TLIF technique might thus be beneficial in the prevention of postoperative immobilization-associated complications such as venous thromboembolism. This trial is registered with DRKS00006135.

    Finland with four other countries participated in the European Union's network project FARMING in 2000 - 2004. The aim of the project was to invite participants from each country representing the food supply chain in a stakeholder group and advance with the groups the networking in building preparedness for accidental contamination of the food production systems. The task of the groups was to evaluate the practicability of management options suggested for reduction of radiation exposure through foodstuffs, and for disposal of waste generated in implementation of these options. The criteria for practicability were effectiveness in reduction of radiation exposure through foodstuffs, technical feasibility, capacity, costs for implementation, secondary costs for waste disposal, socio-economic impact, and acceptability concerning ecology and protection of environment and landscape. Practicable management options aimed at sustainable restoration of food production systems after accidental contamination. The Finnish stakeholder group represented farm production, processing industry, food marketing, catering, advisor organisations for households and agriculture, consumers, nature conservation, the media, experts on environmental impact and authorities responsible for production, safety and security of foodstuffs, food supply and feedstuffs. The group was expected to examine the effect of the Finnish, and, also more generally, northern production conditions on the practicability of the suggested management options. The stakeholder group members first familiarized themselves with intervention after accidental contamination of a large milk production area and thereafter with practicability of individual management options. The evaluation was based on the group members' complementary expertise that very well covered the chain 'from field to fork' whether the issue was related to legislation, production methods, logistics, environmental impacts, or the issues of consumers and

  5. Spent nuclear fuel disposal liability insurance

    Martin, D.W.

    1984-01-01

    This thesis examines the social efficiency of nuclear power when the risks of accidental releases of spent fuel radionuclides from a spent fuel disposal facility are considered. The analysis consists of two major parts. First, a theoretical economic model of the use of nuclear power including the risks associated with releases of radionuclides from a disposal facility is developed. Second, the costs of nuclear power, including the risks associated with a radionuclide release, are empirically compared to the costs of fossil fuel-fired generation of electricity. Under the provisions of the Nuclear Waste Policy Act of 1982, the federally owned and operated spent nuclear fuel disposal facility is not required to maintain a reserve fund to cover damages from an accidental radionuclide release. Thus, the risks of a harmful radionuclide release are not included in the spent nuclear fuel disposal fee charged to the electric utilities. Since the electric utilities do not pay the full, social costs of spent fuel disposal, they use nuclear fuel in excess of the social optimum. An insurance mechanism is proposed to internalize the risks associated with spent fueled disposal. Under this proposal, the Federal government is required to insure the disposal facility against any liabilities arising from accidental releases of spent fuel radionuclides

    1986-01-01

    Unforeseen radiation exposures may be caused by technical or human faults in the utilization of radioactive devices, namely radionuclide sources, as well as from the peaceful uses of nuclear energy; the first instance is in general the more common one. The paper discusses the principal basis for health intervention planning in the case of possible accidental exposures of workers and/or the population to ionizing radiation, also with reference to hypothetical accidents at nuclear power stations. For this last purpose an important aspect is the definition of the 'source term' problem. The main differences existing between 'conventional' and radiation emergencies in the pre-planning of technical and health safety operations are discussed. Even if the general organizational planning is based on similar operating structures, radiation emergencies require a somewhat different approach. Besides the specialized aspects of prophylaxis and therapy which are needed in these cases, radiation emergencies call for a comparison of the social cost, the possible health detriment induced by health-related countermeasures and the specific radiation risk in a single case. In many instances, furthermore, a key role may also be played by psychological factors. Following this philosophy, a flexible organization plan has been drawn up, which consists of three-steps as follows: (1) local and/or regional level; (2) national level; (3) European or international level. For the first two levels, besides the possibility of utilizing health services, there is provision to arrange them into structures of increasing complexity, using modular, integrated and fixed operative units to adapt the intervention to specific aspects of each accident or emergency. The third level is represented by the WHO International Centre of Radiopathology (ICR) in Paris. An official agreement was recently signed by the ENEA and the Centre. (author)

    Full Text Available Abstract Background Accidental poisoning is one of the leading causes of injury in the United States, second only to motor vehicle accidents. According to the Centers for Disease Control and Prevention, the rates of accidental poisoning mortality have been increasing in the past fourteen years nationally. In Texas, mortality rates from accidental poisoning have mirrored national trends, increasing linearly from 1981 to 2001. The purpose of this study was to determine if there are spatiotemporal clusters of accidental poisoning mortality among Texas counties, and if so, whether there are variations in clustering and risk according to gender and race/ethnicity. The Spatial Scan Statistic in combination with GIS software was used to identify potential clusters between 1980 and 2001 among Texas counties, and Poisson regression was used to evaluate risk differences. Results Several significant (p Conclusion The findings of the present study provide evidence for the existence of accidental poisoning mortality clusters in Texas, demonstrate the persistence of these clusters into the present decade, and show the spatiotemporal variations in risk and clustering of accidental poisoning deaths by gender and race/ethnicity. By quantifying disparities in accidental poisoning mortality by place, time and person, this study demonstrates the utility of the spatial scan statistic combined with GIS and regression methods in identifying priority areas for public health planning and resource allocation.

    Full Text Available Background. 4-Aminopyridine (4-AP is a drug that is used to improve motor fatigue in patients suffering from multiple sclerosis (MS. Medication error can occur, as commercial preparation may not be available in some countries. Case Presentation. A 58-year-old woman with progressive MS presented with status epilepticus. She was receiving 4-AP for more than 3 years. The symptoms started soon after the ingestion of a single pill that was supposed to contain 10 mg 4-AP, but further investigations revealed that each pill had been inadvertently prepared with an 100 mg 4-AP concentration. The patient was admitted to the intensive care unit (ICU for appropriate management (orotracheal intubation, sedation, and antiepileptic drugs. The first electroencephalogram (EEG showed abundant irregular spike-waves on the left central regions. Neurological condition gradually improved from day 7, while the EEG did not reveal any more electrical seizures but was still consistent with toxic encephalopathy. The patient stayed in the ICU until day 13. At discharge from the rehabilitation ward (2.5 months later, the patient had not yet recovered her previous cognitive and functional condition. Conclusion. A single 100 mg 4-AP accidental overdose may cause serious immediate complications, with a slow and incomplete neurological recovery.

    Full Text Available The paper describes a fatal case of accidental ingestion of a mixture of hydrochloric acid and hydrofluoric acid. The man was admitted to hospital, where appropriate treatment, adequate to his condition, was instituted. Numerous ventricular fibrillation episodes, for which the patient was defibrillated repeatedly, were observed during the period of hospitalization. The patient was in a critical condition, with progressive symptoms of hypovolemic shock and multiorgan failure. On the next day after admission, signs of electromechanical dissociation progressing to asystole were noted. The instituted resuscitation procedure proved ineffective and the patient died. Autopsy revealed brownish discoloration of the esophageal, gastric, and small intestinal mucous membranes. Numerous ulcerations without signs of perforation were found both in the esophagus and in the stomach. The mucous membrane of the small intestine demonstrated focal rubefactions, whereas no focal lesions of the large intestinal mucosa were seen. Microscopic investigation of the biopsy specimens collected from the stomach, duodenum and small intestine revealed mucous membrane necrosis foci, reaching the deeper layers of the wall of these organs. The mucous membrane of the large intestine was congested. Bioptates obtained from the lungs indicated the presence of hemorrhagic infarcts and focal extravasations. Poisoning with the aforementioned acids with consequent necrosis of the esophageal, gastric, duodenal and small intestinal walls with hemorrhages to the gastrointestinal tract, as well as extravasations and hemorrhagic infarcts in the lungs was considered to be the cause of death.

    Accidental kerosene ingestion continues to cause morbidity and mortality in third world countries, where kerosene is still used for cooking, heating and cleaning. In this prospective study, 78 children aged from 10 months to 5 years were managed at Makassed Hospital in Jerusalem for kerosene ingestion. Respiratory distress developed in 60 (76.90%) children. Two who required mechanical ventilation died. Vomiting, which occurred in 49 cases, did not seem to increase the risk of respiratory complications, suggesting that aspiration occurs with the initial ingestion. Chest X-ray changes were noted in 60% of the children on admission. Pleural effusions occurred in three cases over 24 hours after the incident. CNS manifestations, most likely caused by anoxia, were seen in 27% of the children, but in only two were they severe in the form of convulsions, and both died. Fever occurred in about 50% of the children during their stay in hospital. Severe gastric dilatation developed in the four most severely ill children, two of whom died. The quantity of kerosene ingested by them was estimated to be large.

    Lead (Pb) exposure in dairy cattle is associated with economic losses due to mortality and treatment costs, but with production animals there is also risk to the human food chain. The first objective of this study was to quantify the Pb concentration in milk from Pb-exposed cattle. The second objective was to correlate blood and milk Pb concentrations from individual cows. The third objective was long-term monitoring to determine the duration of milk contamination after exposure ceased. A dairy herd of more than 100 cows was accidentally exposed to Pb-contaminated feed. Milk and blood were collected for Pb analysis. Serial collection of milk samples continued for 2.5 years. The initial concentration of Pb in bulk tank milk was 0.0999 mg l⁻¹. The highest milk Pb concentration from an individual cow was 0.4657 mg l⁻¹ and the highest blood Pb concentration was 1.216 mg l⁻¹. One milk sample collected at the end of the study (day 922) contained 0.0117 mg Pb l⁻¹ of Pb. The calculated relationship between milk (y) and blood (x) Pb concentration was ln(y) = 3.4(x) - 2.21 (R² = 0.98).

    The retention of aerosols by canopies of holm oak trees in a typical Mediterranean forest is studied. Firstly, dry deposition is measured both under and outside the canopy during several months. No clear differences are observed either in the amount or in the chemical composition of the particles collected under and outside the canopy. Secondly, the leaf morphology and anatomy as well as the aerosol deposited onto the leaf surfaces are studied by scanning electron microscopy. Cuticle thickness is measured and differences are observed between young and old leaves. The distribution of aerosol particles over leaf surface is also established. Finally, the possible incorporation into leaves of a radioactive aerosol released in an accidental situation is studied, by means of a sequential extraction procedure using water and an organic solvent. From the results it can be deduced that neither the abiotic layer nor the cuticle play any important role in the retention of caesium. The studied radionuclides are mainly found in particulate form, soluble in water, or incorporated into leaves.

    In case of accidental marine pollution, Cedre and Meteo-France, within the framework of their own public service missions, provide assistance to the French authorities in charge of pollution response. Meteo-France has developed a numerical marine oil pollution transport model, named MOTHY, designed to simulate the transport of oil in three dimensions. A hydrodynamic ocean model is linked to an oil spill model including current shear, vertical movements and fate of the oil. The use of a global atmospheric model for atmospheric forcing enables world-wide application of the model. This oil spill response system has been operational since February 1994. In case of marine pollution, Meteo-France send meteorological forecasts and oil spill drift forecasts to Cedre. In return, by its experimentations and interventions on actual pollution, Cedre is contributing to the improvement and validation of the model. New developments, exercises and training are conducted jointly. This paper summarizes the key features of MOTHY and presents some examples of model applications. (author)

    Full Text Available We report a case of accidental cutaneous burns caused by salbutamol metered dose inhaler. A 9-year-old boy underwent dental extraction at a children's hospital and was incidentally noted to have burn injuries on dorsum of both hands. On questioning, the boy revealed that a few days ago his 14-year-old brother, who is an asthmatic, playfully sprayed his salbutamol metered dose inhaler on the back of both his hands with the inhaler's mouth piece being in direct contact with the patient's skin. On examination, there was a rectangular area of erythema with superficial peeling on the dorsum of both hands, the dimensions of which exactly matched those of the inhaler's mouthpiece. It is possible that the injury could have been a chemical burn from the pharmaceutical/preservative/propellant aerosol or due to the physical effect of severe cooling of the skin or mechanical abrasive effect of the aerosol blasts or a combination of some or all the above mechanisms. This case highlights the importance of informing children and parents of the potentially hazardous consequences of misusing a metered dose inhaler.

    Wildfires take a heavy toll on human health worldwide. Climate change may increase the risk of wildfire frequency. Therefore, in view of adapted preventive actions, there is an urgent need to further understand the health effects and public awareness of wildfires. We conducted a systematic review of non-accidental health impacts of wildfire and incorporated lessons learned from recent experiences. Based on the literature, various studies have established the relationship between one of the major components of wildfire, particulate matter (particles with diameter less than 10 µm (PM10) and less than 2.5 µm (PM2.5)) and cardiorespiratory symptoms in terms of Emergency Rooms visits and hospital admissions. Associations between wildfire emissions and various subclinical effects have also been established. However, few relationships between wildfire emissions and mortality have been observed. Certain segments of the population may be particularly vulnerable to smoke-related health risks. Among them, people with pre-existing cardiopulmonary conditions, the elderly, smokers and, for professional reasons, firefighters. Potential action mechanisms have been highlighted. Overall, more research is needed to better understand health impact of wildfire exposure.

    RECUPERARE method has been developed for operating feedback analysis and built on the French Human Reliability Analysis (HRA) principles. It is used to study the causes of human errors or technical failures occurred in French PWRs and the recovery process of events. Based on an event classification (6 categories) model according to the nature of the link between failure and recovery, the identified and recorded data are: the causes of the defects (technical, human, organizational) and the context in which they appear; the factors of the recovery performance (depending on technical and organizational aspects); a chronological analysis, designed to collect delays between failures and their detection/recovery for each event. About 3600 events reported in French PWRs (1997-2003) had been reviewed through this model. Initially, the weight of factors and the most important factors, which influenced the detection and recovery delay, are defined. For this purpose, the regression Partial Least Square (PLS) is used. Then, to link RECUPERARE results with pre-accidental data, conditional probabilities of events linked between them by a cause and effect relationship are calculated. For this, the Bayesian method with the Bayesian network is built with the PLS obtained results and applied. This constitutes a first approach to take into account in HRA the human and organizational factors highlighted by operating feedback. (author)

    Uranyl acetylacetonate (UAA) is an organic complex of uranium used for military applications as a chemical catalyst in high explosives. It is prepared from depleted uranium metal (in lots of 5 kg to 7 kg) by dissolution in nitric acid, neutralization, and complexation with 2,4-pentanedione; the precipitate is dissolved in benzene and recrystallized, dried, ground, and packaged. About six workers at a small chemical company were exposed over a period of time to UAA powders during routine preparation and packaging of the uranium catalyst. The dissolution characteristics of the inhaled material were unknown and could not be determined from the published scientific literature. A 1.05-g sample of UAA powder was obtained from the responsible regulatory authority for further study to determine its chemical composition, and for dissolution in simulated lung fluid. We found the solubility of UAA to be equivalent to a mixture of 52% ICRP class D and 48% ICRP class W material. The annual limit on intake and the derived air concentration for radiological protection were estimated from this result for airborne exposure to UAA. A recycling biokinetic model was used to estimate both material-specific variations in urinary excretion rates and lung retention with time after accidental intakes. This study provides new information for evaluating future exposures to UAA

    Full Text Available The article contains results of public opinion assessment of the radiation hazard due to consequences of two accidental peaceful nuclear explosions: Globus-1 in the Ivanovo region and Dnepr-1, Dnepr-2 in the Murmansk region. Results of query poll reveal that population knows about peaceful nuclear explosions that were done many years ago near their settlement. Radiation hazard and territory contamination due to these events is estimated by population as rather high. This public opinion is reflected in the information about consequences of peaceful nuclear explosions presented in the Internet and local printed mass media, especially due to consequences of accidental peaceful nuclear explosion Globus-1.

    Full Text Available La deposición del patriarca Ignacio I el 23 de noviembre de 858 y su posterior exilio sumieron a la Iglesia Bizantina en la primera de las grandes crisis post-iconoclastas que habría de conocer. La consagración de Focio como su sustituto el día de Navidad del año 858 lejos de solventar el malestar creado en el seno de la cristiandad de Oriente radicalizó las posiciones de clérigos, hegúmenos y metropolitas dando origen a la disputa conocida como querella fociana. Este conflicto que marcó la segunda mitad del siglo IXbizantino se vio acentuado con el destierro y excomunión de Focio y la restauración de Ignacio (867-877 a la que siguió un segundo patriarcado de Focio (877-886. La presente comunicación pretende analizar la estructuración del partido ignaciano durante los difícilesaños en los que carecieron de su líder y el modo en el que su causa sobrevivió tras la muerte de Ignacio, toda vez que Focio ejercía su ministerio sin tener que lidiar ya con ningún grupo disidente. Para ello nos centraremos principalmente en una fuente que hasta ahora ha pasado inadvertida y cuyo testimonio resulta tremendamente elocuente: el epistolario del patriarca Focio.

    Biosafety of nanomaterials has attracted much attention recently. We report here a case where accidental human eye exposure to biogenic nanosized calcium phosphate in the form of calcifying nanoparticles (CNP) raised a strong IgG immune response against proteins carried by CNP. The antibody titer has persisted over ten years at the high level. The IgG was detected by ELISA using CNPs propagated in media containing bovine and human serum as antigen. The exposure incident occurred to a woman scientist (WS) at a research laboratory in Finland at 1993. CNP, also termed "nanobacteria", is a unique self-replicating agent that has not been fully characterized and no data on biohazards were available at that time. Before the accident, her serum samples were negative for both CNP antigen and anti-CNP antibody using specific ELISA tests (Nanobac Oy, Kuopio, Finland). The accident occurred while WS was harvesting CNP cultures. Due to a high pressure in pipetting, CNP pellet splashed into her right eye. Both eyes were immediately washed with water and saline. The following days there was irritation and redness in the right eye. These symptoms disappeared within two weeks without any treatment. Three months after the accident, blood and urine samples of WS were tested for CNP cultures (2), CNP-specific ELISA tests, and blood cell counts. Blood cell counts were normal, CNP antigen and culture tests were negative. A high IgG anti-CNP antibody titer was detected (see Figure). The antibodies of this person have been used thereafter as positive control and standard in ELISA manufacturing (Nano-Sero IgG ELISA, Nanobac Oy, Kuopio, Finland).

    Accidental canal penetration with attendant complications constitutes one of the reasons for abandoning the use of wires for posterior spinal fusion techniques. However, there is dearth of information on this risk when the wire is introduced through the base of spinous process as against sublaminar passage. This study was designed to evaluate hardware-related postoperative complications, especially canal penetration, in our patients who had spinal process wiring in two types of posterior wiring techniques. Patients who had either of two spinous process wiring techniques formed the population for the study. The clinical records were reviewed and the following data were extracted: Age, sex, diagnosis, operation (fusion type), preoperative neurological status, postoperative neurologic deterioration, other postoperative complication and radiologic evidence of canal encroachment. One hundred and seventy four spinous processes were instrumented in 42 patients. The age of the patients ranged from 11 to 78 years while male to female ratio was 2.5:1. Majority of the spinal wiring were for trauma (29 patients; 69.0) while the remaining were tumor (6; 14.3%), degenerative diseases (4; 9.5%) and infections (3; 7.1%). The Rogers technique was performed in 16 (38.1%) patients while 26 (61.9%) underwent Adeolu et al. technique. One patient (2.3%) had neurologic deterioration while 5 patients (11.1%) had varying type of complications from wound infection to fracture of spinous processes. There was no patient with radiological or clinical evidence of canal compromise. Spinous process wiring techniques for posterior spinal stabilization appears to be safe as demonstrated in this study.

    To look for an association between sleep deprivation and risk of accidental falls (AF) in children. A questionnaire was applied to two groups of children aged 1-14 years, encompassing children observed in an emergency room for AF (G1) and children attending health care visits (HV) (G2). Collected data included demographic characteristics, medical history, previous week's sleep pattern (PWSP), sleep duration and sleep pattern in the preceding 24 h, mechanism of fall, and injury severity. acute or chronic disease or exposure to drugs interfering with sleep. Statistical analyses included Fisher's exact test, Pearson Chi-square, Fisher-Freeman-Halton test, T and Mann-Whitney tests for independent samples, and multivariate logistic regression (α=5%). We obtained 1756 questionnaires in G1 and 277 in G2. Of those, 834 in G1 and 267 in G2 were analyzed. We found an increased risk of AF in boys (OR 1.6; 95% CI 1.2-2.4). After controlling for age, gender, summer holidays, parental education and profession, lack of naps and PWSP were associated with increased risk (OR 2.1; 95% CI 1.3-3.3 and OR 2.7; 95% CI 1.2-6.1). In 3-5 year-old children there was an association between AF and a shorter than usual sleep duration in the previous 24 h (p=0.02). To our knowledge, our study is the largest so far to assess the association between sleep deprivation and childhood injury. It evidences a protective effect of naps in children. Sleep duration of less than 8 h increases risk of AF. Pre-schoolers may be particularly susceptible to sleep deprivation. Copyright © 2011 Elsevier B.V. All rights reserved.

    Highlights: • Conservative early dose of different unit fusion radioactivity release were assessed. • Data of accident level in INES for fusion reactor were proposed. • Method of environmental restoration time after fusion accident was proposed. • The maximum possible accident level for ITER like fusion reactor is 6. • We need 34–52 years to live after the fusion hypothetical accident. - Abstract: As an important index shaping the design of fusion safety system, evaluation of public radiation consequences have risen as a hot topic on the way to develop fusion energy. In this work, the comprehensive public early dose was evaluated due to unit gram tritium (HT/HTO), activated dust, activated corrosion products (ACPs) and activated gases accidental release from ITER like fusion reactor. Meanwhile, considering that we cannot completely eliminate the occurrence likelihood of multi-failure of vacuum vessel and tokamak building, we conservatively evaluated the public radiation consequences and environment restoration after the worst hypothetical accident preliminarily. The comparison results show early dose of different unit radioactivity release under different conditions. After further performing the radiation consequences, we find it possible that the hypothetical accident for ITER like fusion reactor would result in a level 6 accident according to INES, not appear level 7 like Chernobyl or Fukushima accidents. And from the point of environment restoration, we need at least 69 years for case 1 (1 kg HTO and 1000 kg dust release) and 34–52 years for case 2 (1 kg HTO and 10kg–100 kg dust release) to wait the contaminated zone drop below the general public safety limit (1mSv per year) before it is suitable for human habitation.

    Objectives The aims of this study were to (i) investigate the association between night work or long work weeks and the risk of accidental injuries and (ii) test if the association is affected by age, sex or socioeconomic status. Methods The study population was drawn from the Danish version of the European Labour Force Survey from 1999-2013. The current study was based on 150 438 participants (53% men and 47% women). Data on accidental injuries were obtained at individual level from national health registers. We included all 20-59-year-old employees working ≥32 hours a week at the time of the interview. We used Poisson regression to estimate the relative rates (RR) of accidental injuries as a function of night work or long work weeks (>40 hours per week) adjusted for year of interview, sex, age, socioeconomic status (SES), industry, and weekly working hours or night work. Age, sex and SES were included as two-way interactions. Results We observed 23 495 cases of accidental injuries based on 273 700 person years at risk. Exposure to night work was statistically significantly associated with accidental injuries (RR 1.11, 99% CI 1.06-1.17) compared to participants with no recent night work. No associations were found between long work weeks (>40 hours) and accidental injuries. Conclusion We found a modest increased risk of accidental injuries when reporting night work. No associations between long work weeks and risk of accidental injuries were observed. Age, sex and SES showed no trends when included as two-way interactions.

    2018-01-01

    The paper is devoted to the assessment of accidental risks occurring at the works engaged in stone extracting and petroleum production. Two basic kinds of accidents common for stone extracting and petroleum production have been chosen to be discussed in the part under consideration. The most dangerous accidental situation characteristic for a stone milling line is an unsanctioned explosion, UE, of blasting agents used for the development of stone deposits. The analysis of a risk occurrence in certain accidental situations is to be carried out. With reference to petroleum extraction, a combustibles and lubricants (C & L) explosion is the most dangerous of characteristic accidental situations. To reveal the most probable causes of accidental situations to be realized, a graph of cause and effect relations has been constructed for each of the accidental situations most probable causes to real situation of an accident. Disasters of a natural origin are the most probable causes of unsanctioned explosions at the deposits of stone raw materials. Technology related natural disasters are the most probable causes of unsanctioned explosions to be realized at multiple well platforms engaged in petroleum production.

    Accidental falls are a major public health concern among people of all ages. Little is known about whether an individual-level housing-based socioeconomic status measure is associated with the risk of accidental falls. Among 12,286 Mayo Clinic Biobank participants residing in Olmsted County, Minnesota, subjects who experienced accidental falls between the biobank enrollment and September 2014 were identified using ICD-9 codes evaluated at emergency departments. HOUSES (HOUsing-based Index of SocioEconomic Status), a socioeconomic status measure based on individual housing features, was also calculated. Cox regression models were utilized to assess the association of the HOUSES (in quartiles) with accidental fall risk. Seven hundred eleven (5.8%) participants had at least one emergency room visit due to an accidental fall during the study period. Subjects with higher HOUSES were less likely to experience falls in a dose-response manner (hazard ratio: 0.58; 95% confidence interval: 0.44-0.76 for comparing the highest to the lowest quartile). In addition, the HOUSES was positively associated with better health behaviors, social support, and functional status. The HOUSES is inversely associated with accidental fall risk requiring emergency care in a dose-response manner. The HOUSES may capture falls-related risk factors through housing features and socioeconomic status-related psychosocial factors. Copyright © 2017 Elsevier Inc. All rights reserved.

  9. Rapid removal of sodium isotopes from the body following accidental internal contamination

    International Nuclear Information System (INIS)

    Palmer, H.E.

    1975-01-01

    The extensive use of liquid sodium as the primary coolant for fast breeder reactors presents human safety hazards from both the chemical toxicity of the sodium oxide and the radioactive toxicity of the large quantities of 24 Na and 22 Na in case of a rupture in the liquid sodium piping. Although the effects of the chemical toxicity are expected to be very immediate and more severe, the radioactive toxicity is also of significant concern. Other sources of radioactive sodium contamination exist in the nuclear industry. This paper describes some procedures which can significantly reduce the radiation dose to the body from 24 Na and 22 Na which might be accidentally inhaled or ingested. Studies with rats indicate that the retention time of the sodium isotopes which have exchanged with the body sodium pool can be reduced by a factor of 10 by ingestion of high levels of stable sodium. In addition, the ingestion of a sodium salt at the time or immediately after the inhalation incident could result in at least 60 percent or more of the inhaled radioactive sodium to be excreted before it exchanges with the body sodium pool. The combined effects of both immediate and sustained sodium ingestion in rats can result in a radiation dose from 22 Na of only 4 percent or less of that which would result if no additional salt is administered. The dose reduction for 24 Na would not be as much as that for 22 Na but would be significant. The tolerance for high levels of stable sodium intake in humans will be discussed and optimum intakes will be suggested which will provide the maximum radioactive sodium excretion with minimum harm to the physiological processes of the body

    Highlights: • Accidental loss of pool coolant due to leakage in a PWR SFP was studied using MAAP5. • The effect of emergency ventilation on the accident progression was investigated. • The effect of emergency injection on the accident progression was discussed. - Abstract: A large loss of pool coolant/water accident may be caused by extreme accidents such as the pool wall or bottom floor punctures due to a large aircraft strike. The safety of SFP under this circumstance is very important. Large amounts of radioactive materials would be easily released into the environment if a severe accident happened in the SFP, because the spent fuel pool (SFP) in a PWR nuclear power station (NPS) is often located in the fuel handing building outside the reactor containment. To gain insight into the loss of pool coolant accident progression for a pressurized water reactor (PWR) SFP, a computational model was established by using the Modular Accident Analysis Program (MAAP5). Important factors such as Zr oxidation by air, air natural circulation and thermal radiation were considered for partial and complete drainage accidents without mitigation measures. The calculation indicated that even if the residual water level was in the active fuel region, there was a chance to effectively remove the decay heat through axial heat conduction (if the pool cooling system failed) or steam cooling (if the pool cooling system was working). For sensitivity study, the effects of emergency ventilation and water injection on the accident progression were analyzed. The analysis showed that for the current configuration of high-density storage racks, it was difficult to cool the spent fuels by air natural circulation. Enlarging the space between the adjacent assemblies was a way of increasing air natural circulation flow rate and maintaining the coolability of SFP. Water injection to the bottom of the SFP helped to recover water inventory, quenching the high temperature assemblies to prevent

    After the accident to No. 1 pile at Windscale on October 10, 1957 (Atomic Energy Office, 1957), the Atomic Energy Authority asked the Medical Research Council for advice on the maximum intake of certain radioactive isotopes that should be regarded as permissible, under emergency conditions, for members of the general population living in, or deriving food from, an area contaminated owing to an accident to a reactor. The Council's Committee on Protection against Ionizing Radiations, together with its Subcommittees on Internal and External Radiations, has considered this problem, and concludes that the intake of radioactive materials by ingestion of contaminated food would generally be the limiting source of hazard after any such accident. Intake by inhalation, or radiation from the exterior, would become of importance only in rather special circumstances. In the following report, therefore, the Committee proposes maximum permissible levels of dietary contamination for the relevant isotopes in the emergency conditions envisaged. In proposing these levels, the Protection Committee has used the fullest information available on the radiation doses that would be delivered to different body tissues and at different ages by the isotopes concerned, and on the ways in which these materials would enter the body

    The radiological consequences of a beyond design-basis accident at an NPP for a VVER-1000 reactor are evaluated. Using the software code COSYMA and accounting for radioiodine activity release to the atmosphere at the early stage of the accident, the radionuclide concentration in air and ground deposition densities were estimated. Inhalation and ingestion thyroid doses to different population sub-groups have been calculated. Using modern knowledge about the risk of radiation-induced cancer, the radiological danger of radionuclides released is evaluated for different exposure pathways. Thyroid doses and risk was estimated for populations living at different distances from the NPP. The comparative analysis of exposure pathways and radiological danger of the radionuclides in release during early and intermediate stage of accident has conducted. (author)

    With the growing use of nuclear power and threat from illegal nuclear smuggling nuclear forensic provides an aid to the law enforcement to trace back modus operandi of such threats. Extensive nuclear proliferation, race among countries to acquire nuclear capability and global terrorism scenario has mandated Nuclear Forensic Science technology to tackle nuclear threats. Gamma spectrometry, alpha spectrometry, thermal ionization mass spectrometry, inductively coupled plasma mass spectrometry are employed for characterization and relative isotopic composition determinant of Nuclear material and techniques like SEM transmission electron TEM, FT-IR, GC-MS, Electrophoretic technique are used to characterize the contaminated materials in order to deceive investigative agencies. The present paper provide systematic forensic methodology for nuclear and radioactive materials encountered at any crime scene due to any accidental discharges or military activities. (author)

  14. Simulation of thermal hydraulics accidental transients. Evaluation of MAAP5.02 versus CATHAREv2.5

    Bittan, Jeremy

    2014-01-01

    The Modular Accident Analysis Program (MAAP) is a deterministic code developed by EPRI that can simulate the response of light water moderated nuclear power plants during accidental transients for Probabilistic Risk Analysis (PRA) applications. It can as well simulate severe accident sequences, including actions taken as part of the Severe Accident Management Guidelines (SAMGs). EPRI indicates that the latest version of the code - MAAP5.02 - benefits from major enhancements, in particular concerning the thermal hydraulics in the primary side. This code revision takes into account momentum equations allowing, to model thermal hydraulics transient with a good accuracy. EDF is interested in using MAAP5.02 as an incidental/accidental transient’s simulation tool for the management of crises on its 58 PWRs. In particular, it could evaluate the time before core uncovers, core melting and fission product releases. In order to assess MAAP5.02 ability to simulate accidental transients prior to core uncovery, EDF has compared MAAP5.02 results to the code used as a reference to simulate thermal hydraulics transients in France: CATHARE (that stands for Code for Analysis of Thermal hydraulics during an Accident of Reactor and safety Evaluation). CATHARE is a system code for PWR safety analysis, accident management, definition of plant operating procedures and for research and development. It is also used to quantify conservative analysis margins and for licensing. It is based on a 2-fluid 6-equation model. The version of CATHARE used for the comparison is CATHAREv2.5 – 2 (one of the latest CATHARE versions). Several transient analyses on LOCA and non LOCA transients have been performed by EDF. Transients at full power conditions as well as in shutdown states have been considered. Here are some of EDF analyzed transients: LOCA (small break on cold leg), LOOP (Loss Of Offsite Power), SGTR (Steam Generator Tube Rupture). The comparisons performed tend to prove that the

    Full Text Available Se estima que aproximadamente un millón o más de pacientes se realizan cirugía refractiva al año. Es por eso que con el envejecimiento son cada día más frecuentes los pacientes con catarata, a quienes previamente se les ha efectuado cirugía refractiva. El cálculo inexacto de la potencia dióptrica de la lente a implantar en la intervención de estos es también un problema de importancia creciente y con él la sorpresa refractiva. Este es mucho más complejo de lo normal, ya que existen dos fuentes de error: la incorrecta predicción de la posición efectiva de la lente por parte de la fórmula y la determinación errónea de la potencia de la córnea por parte de la queratometría. La corrección de estos dos factores permitirá realizar un cálculo correcto en estos ojos. De ahí la motivación para realizar una búsqueda actualizadas de los últimos diez años de diversos artículos publicados, con el objetivo de describir los principios para el cálculo de la lente intraocular tras cirugía refractiva corneal. Se utilizó la plataforma Infomed, específicamente la Biblioteca Virtual de Salud, con todos sus buscadores.

    Full Text Available El artículo examina la relación entre los actuales procesos de globalización, la intensificación de los flujos migratorios internacionales y los problemas de convivencia interétnica con las minorías inmigrantes en Europa, en particular, en relación con inmigrantes de credo islámico, tras los atentados del 11 de septiembre. En nuestros días, las migraciones internacionales pueden ser vistas como la imagen deformada de las contradicciones que caracterizan una globalización que, por una parte, ahonda la división y la exclusión y, por otra, retira la regulación política en unos mercados mientras introduce más política restrictiva en otros. Estas contradicciones, lejos de detener los flujos migratorios, los está incentivando. Se examinan también los límites y las posibilidades de algunos de los modelos de convivencia interétnica más debatidos en la actualidad, en particular la multiculturalidad y la interculturalidad. Frente al clima de sospecha generalizada hacia los inmigrantes de credo islámico, se propone un esfuerzo de aproximación y conocimiento mutuo, que derribe barreras y tópicos, analice los verdaderos orígenes de las expresiones más violentas del islamismo y, a través de un diálogo intercultural, logre construir un marco de valores y referentes universalmente aceptados, sobre los que pueda basarse una convivencia práctica fecunda.

  17. Towards the operational estimation of a radiological plume using data assimilation after a radiological accidental atmospheric release

    In the event of an accidental atmospheric release of radionuclides from a nuclear power plant, accurate real-time forecasting of the activity concentrations of radionuclides is required by the decision makers for the preparation of adequate countermeasures. The accuracy of the forecast plume is highly dependent on the source term estimation. On several academic test cases, including real data, inverse modelling and data assimilation techniques were proven to help in the assessment of the source term. In this paper, a semi-automatic method is proposed for the sequential reconstruction of the plume, by implementing a sequential data assimilation algorithm based on inverse modelling, with a care to develop realistic methods for operational risk agencies. The performance of the assimilation scheme has been assessed through the intercomparison between French and Finnish frameworks. Two dispersion models have been used: Polair3D and Silam developed in two different research centres. Different release locations, as well as different meteorological situations are tested. The existing and newly planned surveillance networks are used and realistically large multiplicative observational errors are assumed. The inverse modelling scheme accounts for strong error bias encountered with such errors. The efficiency of the data assimilation system is tested via statistical indicators. For France and Finland, the average performance of the data assimilation system is strong. However there are outlying situations where the inversion fails because of a too poor observability. In addition, in the case where the power plant responsible for the accidental release is not known, robust statistical tools are developed and tested to discriminate candidate release sites.

    Full Text Available En el presente estudio se estima la mortalidad proporcional por accidentes de trabajo provocados por violencia interpersonal en Brasil, entre 2000 y 2010. Se analizaron los datos del Sistema de Información sobre Mortalidad, basados en los informes estadísti- cos de defunción del Ministerio de Salud de Brasil, los cuales incluyen un campo para el registro de accidentes de trabajo que debe ser completado en toda defunción por causas externas. Se identificaron 1.368.732 casos de defunciones por causas externas, 31.576 (2,3% por accidentes de trabajo y solo 226 (0,02% por accidentes de trabajo con violen- cia interpersonal. Cerca del 80% de los informes estadísticos de defunción no tenían el campo “accidente de trabajo” completado. La mayor cantidad de casos ocurrió entre hom- bres (94,3% de 25-34 años, con nivel de escolaridad medio, ubicados en la región sudeste y noreste, que trabajan principalmente en la producción de bienes y servicios industriales y la actividad agropecuaria. La mayoría de los casos fueron causados por armas de fuego, seguidos por armas blancas, con un aumento relativo de estos últimos en el período estu- diado. Los resultados sugieren un gran subregistro de diagnósticos que reconocen la rela- ción con el trabajo. Se hace necesaria una mejor capacitación en el llenado de los informes estadísticos, así como estudios que cuantifiquen el subregistro de accidentes de trabajo y accidentes de trabajo con violencia interpersonal.

    The exposures of urban populations to the radiation derived from the deposition, after accidental atmospheric releases, of I37 Cs, 134 Cs, 129 I, 131 I, 133 I, 89 Sr, l03 Ru and 106 Ru were assessed, using the integrated system for the evaluation of environmental radiological impact in emergency situations (SIEM), developed by the Instituto de Radioprotecao e Dosimetria (IRD) / Comissao Nacional de Energia Nuclear (CNEN). These radionuclides are fission products likely to be emitted in the occurrence of severe nuclear reactor accidents. Their environmental behaviour in urban areas, due to their deposition in soil, in urban surfaces and in vegetable-garden food products, such as leafy and non-leafy vegetables, were analyzed, and dose assessments at the short, medium and long terms were performed, with and without the application of protective measures for reduction of doses. Simulations of unitary initial deposition for each radionuclide and of two different potential accidents involving pressurized water reactors (PWR), with different source terms and distinct deposition for each radionuclide, were performed. Results were analyzed on the basis of the relative relevance of radionuclides and pathways for the exposure of members of the public, as a function of age and time after the release. It was also performed an assessment of the effectiveness of protective measures as a function of the moment of their implementation. (author)

  20. Guidelines for agricultural countermeasures following an accidental release of radionuclides

    International Nuclear Information System (INIS)

    1994-01-01

    The Chernobyl accident in 1986 caused significant radioactive contamination of the environment over widely separated areas, some relatively remote from the site. Considerable scientific research was stimulated directly and indirectly and a good deal of practical experience was obtained in dealing with the aftermath. The collation of the relevant information and experience concerning the transfer of radionuclides through food chains and ways of reducing this transfer is a prudent insurance for the management of agriculture should a major nuclear accident occur again. Work to this end was begun in 1990 by a consultants group convened in a co-ordinated research programme of the IAEA and the CEC on the Validation of Models for the Transfer of Radionuclides in Terrestrial, Urban and Aquatic Environments (VAMP). The work was further developed by a joint programme of the IAEA Division of Nuclear Safety and the Agrochemicals and Residues Section of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture entitled ''Alleviating the Adverse Effects of Excessive Radionuclide Contamination of the Agricultural Environment''. The present Guidelines are an output of this programme and are intended to assist those charged with administrative, scientific and advisory responsibilities to prepare more detail plans specific to the local conditions. 80 refs, 1 fig., 20 tabs

    In 1989, a Radiological Transmission and Early Warning System (SYTAR) came into being in order to harmonize radioactivity surveillance methodologies and furthermore to trigger off an alert throughout the networks whenever an unusual degree of radioactivity is detected. SYTAR is a remote permanent system linking up a national electronic access and the radiation protection services of nuclear facilities located on the mainland. The structure of the network are particularly presented in the framework of a drill organized on october 1991 in the south-east of France. During this drill, an accident was simulated on a ghost nuclear power plant located in the Cadarache Nuclear Center. A large number of samples were taken from filtered aerosols, soils, grass, milk, vegetables, food stuff; they were contaminated with Caesium 137 and Iodine 131 before to be sent to laboratories for measurements. The results of measurements were transmitted to the actors of the drill using SYTAR network. They permit to determine the exclusion area, the radiological impacts and counter-measures. (author)

    Full Text Available Background Infectious causes of childhood deaths in the world have decreased substantially in the 21st century. This trend has exposed accidental deaths as an increasingly important future challenge. Presently, little is known about the cause structure of accidental childhood deaths in low– and middle–income country (LMIC settings In this paper, we aim to establish cause structure for accidental deaths in children aged 0–4 years in China in the year 2010. Methods In this paper, we explored the database of 208 multi–cause child mortality studies in Chinese that formed a basis for the first published estimate of the causes of child deaths in China (for the year 2008. Only five of those studies identified specific causes of accidental deaths. Because of this, we searched the Chinese medical literature databases CNKI and WanFang for single–cause mortality studies that were focused on accidental deaths. We identified 71 further studies that provided specific causes for accidental deaths. We used epidemiological modeling to estimate the number of accidental child deaths in China in 2010 and to assign those deaths to specific causes. Results In 2010, we estimated 314 581 deaths in children 0–4 years in China, of which 31 633 (10.1% were accidental. Accidental deaths contributed 7240 (4.0% of all deaths in neonatal period, 8838 (10.5% among all post–neonatal infant deaths, and 15 554 (31.7% among children with 1–4 years of age. Among four tested models, the most predictive was used to establish the likely cause structure of accidental deaths in China. We estimated that asphyxia caused 9490 (95% confidence interval (CI 8224–11 072, drowning 5694 (95% CI 5061–6327, traffic accidents 3796 (95% CI3163–4745, poisoning 3163 (95% CI 2531–3796 and falls 2531 (95% CI 2214–3163 deaths. Based on medians from a few rare studies, we also predict 633 (95% CI 316–1265 deaths to be due to burns and 316 (95% CI 0–633 due to falling objects

    Full Text Available The purpose of this study was to examine county and state-level accidental poisoning mortality trends in Pennsylvania from 1979 to 2014.Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 10 codes X40-X49 from 1979 to 2014 for ages 15+ using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 1979 to 2014, overall and by sex, age group, and race. Joinpoint regression was used to detect statistically significant changes in trends of age-adjusted mortality rates.Rate ratios for accidental poisoning mortality in Pennsylvania increased more than 14-fold from 1979 to 2014. The largest rate ratios were among 35-44 year olds, females, and White adults. The highest accidental poisoning mortality rates were found in the counties of Southwestern Pennsylvania, those surrounding Philadelphia, and those in Northeast Pennsylvania near Scranton.The patterns and locations of accidental poisoning mortality by race, sex, and age group provide direction for interventions and policy makers. In particular, this study found the highest rate ratios in PA among females, whites, and the age group 35-44.

    Objetivo: Evaluar la rigidez de la membrana limitante interna (MLI) humana y evaluar los posibles cambios de las propiedades mecánicas tras administrar una inyección intravítrea de ocriplasmina para tratar la tracción vitreomacular. Métodos: Este estudio se compone de una serie de casos intervencionales y comparativos de 12 muestras de MLI extraídas mediante cirugía y obtenidas de forma consecutiva de 9 ojos de 9 pacientes después de someterse sin éxito a vitreólisis farmacológica con ocriplasmina. Durante el mismo periodo de tiempo, 16 muestras de otros 13 ojos sin tratamiento con ocriplasmina se obtuvieron mediante vitrectomía y sirvieron como controles. Todos los pacientes presentaron agujeros maculares o tracción vitreomacular y se sometieron a vitrectomía con disección de la MLI tanto con tinción con azul brillante (AB) como sin ella. Todas las muestras se analizaron con un microscopio de fuerza atómica con imágenes de las regiones de 25 × 25 μm. En todas las muestras, se analizaron tanto la parte de la retina como la del vítreo de la MLI. Resultados: La microscopia de fuerza atómica no reveló diferencias significativas en cuanto a elasticidad de las muestras de MLI extraídas de ojos con o sin tratamiento con ocriplasmina. Las áreas onduladas de la parte de la retina presentaron una mayor rigidez que la parte del vítreo de la MLI. La cartografía topográfica tanto de la parte del vítreo como de la retina de la MLI no mostró ninguna alteración aparente de la morfología en ojos tratados con ocriplasmina en comparación con los ojos no tratados. La tinción con azul brillante conllevó un aumento de la rigidez tisular. Conclusiones: Las inyecciones intravítreas de ocriplasmina no varían las propiedades biomecánicas de la MLI humana. No existen pruebas de un posible efecto enzimático que interfiera con la rigidez de esta membrana basal. © 2017 S. Karger AG, Basel.

    Background. Child abuse specialists rely heavily on diagnostic neuroimaging. Objectives. Study objectives were: (1) to compare the frequencies of six specific intracranial CT abnormalities in accidental and non-accidental pediatric head trauma, and (2) to assess interobserver agreement regarding these CT findings. Materials and methods. Three pediatric radiologists blindly and independently reviewed cranial CT scans of pediatric patients who sustained closed head trauma between 1991 and 1994. All patients were less than 4 years of age. Study cases included thirty-nine (50 %) with non-accidental head trauma and thirty-nine (50 %) with accidental head trauma. Each scan was evaluated for the presence or absence of the following six intracranial findings: (1) interhemispheric falx hemorrhage, (2) subdural hemorrhage, (3) large (non-acute) extra-axial fluid, (4) basal ganglia edema, (5) posterior fossa hemorrhage, and (6) frontal-parietal shearing tear(s). Interobserver agreement was calculated as the percentage of total cases in which all reviewers agreed a specific CT finding was present or absent. Diagnosis required independent agreement by all three pediatric radiologists. The frequencies of these six intracranial CT abnormalities were compared between the two study groups by Chi-square analysis and Fisher`s exact test. Results. Interobserver agreement between radiologists was greater than 80 % for all lesions evaluated, with the exception of frontal-parietal shearing tear(s). Interhemispheric falx hemorrhage, subdural hemorrhage, large (non-acute) extra-axial fluid, and basal ganglia edema were discovered significantly more frequently in non-accidental trauma (P {<=}.05). Conclusion. Although not specific for child abuse, discovery of these intracranial CT abnormalities in young patients should prompt careful evaluation of family and injury circumstances for indicators of non-accidental trauma.

    Accidental injection or leakages of various chemical disinfectants used during root canal preparation into adjacent tissues have been shown to have deleterious effects on surrounding tissue. Formocresol (FC) is an effective intracanal disinfectant used in endodontic procedures. However, it is known to have harmful effects into adjacent tissues. The aim of this article is to present an unusual case in which a 28-year-old male patient developed gingival and bone necrosis after the accidental injection of FC instead of local anesthetic solution for tooth extraction and to review cases in the literature where complications have occurred due to the use of FC.

    2011-11-01

    Full Text Available Abstract Fortunately radiation accidents are infrequent occurrences, but since they have the potential of large scale events like the nuclear accidents of Chernobyl and Fukushima, preparatory planning of the medical management of radiation accident victims is very important. Radiation accidents can result in different types of radiation exposure for which the diagnostic and therapeutic measures, as well as the outcomes, differ. The clinical course of acute radiation syndrome depends on the absorbed radiation dose and its distribution. Multi-organ-involvement and multi-organ-failure need be taken into account. The most vulnerable organ system to radiation exposure is the hematopoietic system. In addition to hematopoietic syndrome, radiation induced damage to the skin plays an important role in diagnostics and the treatment of radiation accident victims. The most important therapeutic principles with special reference to hematopoietic syndrome and cutaneous radiation syndrome are reviewed.

    This article comprises three parts: 1 - some general considerations aiming at explaining the main motivations of safety researches, and at briefly presenting the important role of some organisations in the international conciliation, and the most common approach used in safety researches (analytical experiments, calculation codes, global experiments); 2 - an overview of some of the main safety problems that are the object of worldwide research programs (natural disasters, industrial disasters, criticality, human and organisational factors, fuel behaviour in accidental situation, serious accidents: core meltdown, corium spreading, failure of the confinement building, radioactive releases). Considering the huge number of research topics, this part cannot be exhaustive and many topics are not approached; 3 - the presentation of two research programs addressing very different problems: the evaluation of accidental releases in the case of a serious accident (behaviour of iodine and B 4 C, air infiltration, fission products release) and the propagation of a fire in a facility (PRISME program). These two programs belong to an international framework involving several partners from countries involved in nuclear energy usage. (J.S.)

    2002-01-01

    Accidental hypothermia is a rare clinical picture with different causes. Specific features are shown by patients who have accidents in water, due to rapid cooling. The SARRRAH project (Search and Rescue, Resuscitation and Rewarming in Accidental Hypothermia) was launched to secure fast and professional medical care right up to rewarming by extracorporal circulation. The University of Rostock takes part in this project. Based on the course of accidental hypothermia in fifteen patients, the authors report on the treatment of this life-threatening situation with special regard to the use of extracorporal circulation and present their first results. The core temperature of these patients lay between 16.0 and 34.0 degrees C. Eight of the patients had cardiac arrest at the scene of the accident. Seven of the patients with cardiac arrest were treated with extracorporal circulation in addition to cardiopulmonary resuscitation, which was started pre-clinically and continued in hospital. In one patient, extracorporal circulation was used at an initial temperature of 25.4 degrees C without previous cardiopulmonary resuscitation. Six of these fifteen patients with accidental hypothermia died. Five of the non-survivors belonged to the group of eight patients who were rewarmed by extracorporal circulation. With one exception, they also had the lowest core temperatures. Only a homogeneous and up-to-date documentation will allow further conclusions to be made for improving the concept of therapy.

    During the last few years the radiopathology service of the Curie Foundation has admitted more than a hundred patients who were followed and treated for irradiation or suspected irradiation after a work accident. Accidents followed by clinical symptoms account for about half the cases examined. Some of these clinical signs were benign whereas others developed very seriously, all possible conditions between these two extremes being represented. This report neglects cases of high total exposure and deals only with those of partial irradiation where local symptoms predominate, usually at the distal extremities of the upper limbs and exceptionally at the root or distal extremity of the lower limbs. Six clinical cases were selected as particularly revealing and are discussed below: accidental exposure of both hands to an iridium-192 source; chronic exposure to X-rays (left hand and right lower half-lip); accidental exposure of the right hand and antero-external face of the right thigh to a iridium-192 source; acute accidental exposure of the left hand to X-rays emitted under 50 kV; accidental exposure of both hands to cobalt-60 radiation; radiolesions of the left lower limb following a critical power excursion (gamma rays and neutrons) [fr

    Accidents are a preventable cause of death. Unfortunately it accounts for a large number of deaths in many societies. In Kuwait, road traffic accidents (RTA) is the leading cause of death in young people. The study investigated the patterns of accidental deaths in Kuwait, one of the Gulf States which incorporates a wide variety of multi-ethnic communities. The study was retrospective from 2003-2009. Data of forensic cases were collected from the general department of criminal evidence (GDCE) in the ministry of interior (MOI).We attempted to find out causes of accidental death and the prevelance of each cause. Furthermore, the relationship of demographic factors (eg. Age, sex, marital status and nationality) with each cause of accidental death in Kuwait were studied. The material of this study constituted a total of 4886 reported accidental deaths referred for Medico-legal examination. Road traffic accidents was by far the most prevalent cause of death (64.6%) followed by fall from height (13.1%). Poisoning and mine explosions were amongst the least common causes. The government of Kuwait needs to take strong measures to promote safety in the workplace and households by educational campaigns.

    Resistance training has previously been purported to be unsafe and ineffective in children. The purpose of this investigation was to evaluate resistance training-related injuries presenting to U.S. emergency rooms by age, type, and mechanism of injury. We hypothesized that older athletes would sustain greater percentages of joint sprains and muscle strains, whereas younger athletes would sustain a greater percentage of accidental injuries that would result in an increased percentage of fractures in youths. The U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System was queried from 2002 to 2005 using the CPSC code for "Weightlifting." Subjects between the ages of 8 and 30 were grouped by age categories 8 to 13 (elementary/middle school age), 14 to 18 (high school), 19 to 22 (college), and 23 to 30 (adult). Injuries were classified as "accidental" if caused by dropped weight or improper equipment use. Multiple logistic regression was used to compare accidental injuries between age groups. The sample consisted of 4,111 patients. Accidental injuries decreased (p 14 to 18 > 19 to 22 years = 23 to 30 years. Conversely, sprain/strain injuries increased in each successive age group (p training-related joint sprains and muscle strains than adults. The majority of youth resistance training injuries are the result of accidents that are potentially preventable with increased supervision and stricter safety guidelines.

    1977-08-01

    In this report an assessment is made of the radiological consequences of notional accidental releases of activity from a fast breeder reactor under certain circumstances. It was prepared under contract to the Nuclear Installations Inspectorate (Health and Safety Executive) to assist them in making a preliminary safety assessment of fast reactors. The range of releases considered in the report was specified by the Inspectorate and comprises the vaporisation and release of varying fractions of the core of a 1300 MW(e) reactor. Two cases are evaluated depending on assumptions relating to the remainder of the core. No attempt is made to assign any probability to the occurrence of a given release; the report provides no more than a part of the information necessary for a safety assessment and is to be considered only within this limited context. The subject is dealt with under the following headings: introduction; parameters used in the assessment; atmospheric dispersion; pathways of exposure and dosimetric models; doses associated with the release of one tonne of fuel; biological effects; consequences of releases in which the nuclide composition differs from that in the fuel.

We present the case of a 41 year old female patient with repetitive episodes of tachycardia due to nodal reentry who was treated with radiofrequency ablation. Immediately after the procedure she presented focal neurologic deficit consistent with ischemic stroke in the right medial cerebral artery territory. Angiography with angioplastia and abxicimab was performed and then tissue plasminogen activator (rtPA was locally infused, with appropriate clinical and angiographic outcome.

    Nuclear fuel remains in the core during the outage of CANDU unit, but there are still nuclear safety risks such as reactor accidental criticality, fuel element failure due to inability to properly remove residual heat. Furthermore, these risks are aggravated by the weakening plant system configuration and multiple cross operations during the outage. This paper analyzes the phases where there are potential nuclear safety risks on the basis of the typical critical path arrangement of the outage of Qinshan NPP 3 and introduces a series of CANDU-specific risk control measures taken during the past plant outages to ensure nuclear safety during the unit outage.

    International Nuclear Information System (INIS)

    Collins, L.

    1988-01-01

    Estimates of the risks of exposing an embryo or fetus to radiation are discussed. Recommendations are made about the policies a nuclear medicine department should develop for handling cases of accidental irradiation of an embryo or fetus. The choices available where a known pregnancy is involved and diagnostic radiology is required are outlined. Only necessary examinations should be performed and care taken to avoid or minimise irradiation of the fetus. The nuclear medicine physician must be prepared to make (and defend if necessary) an informed decision on whether to proceed with an examination and must also be in a position to discuss the risks with anxious parents

    In the case of accidental release of hazardous gases in the atmosphere, the emergency responders need a reliable and fast tool to assess the possible consequences and apply the optimal countermeasures. A number of models for the prediction and simulation of hazard areas affected by accidental releases of toxic gases are available worldwide. Modelling accidental releases may be required for a variety of reasons: for analyzing different accidental toxic release scenarios ("worst-case scenarios"), for preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management (e.g. in the frame of the SEVESO directive). Depending on the demand and the particular purposes, the choice of the appropriate model is up to the authorities. The one year project was funded by the Austrian Science and research liaison Office (ASO, www.aso.zsi.at) as a part of the program: Research Cooperation and Networking between Austria, the public higher education institutions in Kosovo and South Eastern Europe. The project was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG, http://www.zamg.ac.at) in cooperation with the University of Prishtina (Kosovo, www.uni-pr.edu and the National Institute of meteorology and Hydrology (NIHM Bulgaria, www.meteo.bg). One of the main purposes of the project was to provide the both partners with basic knowledge in modelling with accidental release of toxic gases, based on the practical experience of the meteorologists from the ZAMG in the area. This knowledge can be used as scientific response to society driven current or upcoming problems especially in Kosovo. The activities involved know-how transfer on European standards and practice among the project partners, as well as joint efforts to adapt and disseminate the scientific methods and results in Kosovo. Within the project, the partners from Kosovo and Bulgaria were introduced to the atmospheric dispersion model (ALOHA - Areal

  16. Suicide and accidental death in Australia's rural farming communities: a review of the literature.

    2014-01-01

    Australia's farmers constitute a heterogeneous group within the rural population. This literature review incorporates four broad areas: an understanding of farming communities, families and individuals and the contexts in which they live and work; an exploration of the challenges to morbidity and mortality that these communities face; a description of the patterns of suicide and accidental death in farming communities; and an outline of what is missing from the current body of research. Recommendations will be made on how these gaps may be addressed. In developing this comprehensive literature review, a snowballing and saturation approach was adopted. Initial search terms included suicid*, farm*, accident*, fatal*, death, sudden death, rural OR remote, Australia and NOT Australia. Databases searched included SCOPUS, PubMed, Proquest and SafetyLit; research from 1995 onwards was examined for relevance. Earlier seminal texts were also included. Reference lists of retrieved articles were searched and citations explored for further relevant research material. The primary focus was on Australian peer-reviewed research with supplementary grey literature. International material was used as examples. The literature variously describes farmers as members of both rural farming communities and farming families, and as individuals within an occupational classification. Within each of these classifications, there is evidence of the cumulative impact of a multiplicity of social, geographical and psychological factors relating to work, living and social arrangements that impact the health and wellbeing of Australia's farmers and their families, particularly accidental death and suicide. Research consistently demonstrates traumatic death to be at a greater rate than in the general Australian population, with reductions found more recently in some modes of farming-related accidental death. Patterns of accidental death and suicide are commonly linked to the changing shape of

    2001-04-01

    Full Text Available The evolution of the mechanical properties, static and dynamic, of two different composites with thermoplastic matrix and glass-fiber fabric or carbon-fiber fabric as reinforcement after immersing in a hydrogen peroxide solution have been analyzed. The tensile strength suffered a decrease after exposure of the materials in the solution. This decrease was more important in the case of the glass-fiber composite than in carbon-fiber composite. On the other hand, the interlaminar shear strength suffered also an important decrease, but in this case more substantial for the carbon-fiber composite. Finally, the fatigue behavior of the materials have been studied after exposure to the hydrogen peroxide solution. The results correlate with the tensile results.

    Se ha analizado la evolución de las propiedades mecánicas, tanto estáticas como dinámicas, de dos composites de matriz termoplástica reforzados con tejido de fibra de vidrio y fibra de carbono, tras mantener inmersas probetas de ambos materiales en una solución de agua oxigenada, empleada en el método TCF, útil en la fabricación de papel. Se observa, desde el punto de vista de la resistencia a tracción, una pérdida de propiedades mucho mayor en el caso del compuesto con fibra de vidrio que en el de fibra de carbono. En cambio, en las curvas correspondientes a la variación de la resistencia a cortadura interlaminar, se aprecia una pérdida muy importante, pero superior para el compuesto de fibra de carbono. Por último, también se mostrará el comportamiento de ambos compuestos a fatiga tras permanencia en la solución de agua oxigenada. Los resultados obtenidos muestran una gran correlación con los generados a partir de los ensayos de tracción.

    The acute radiation syndrome has been characterized in different ways that involve risk for life and health of the people overexposed to ionizing radiations. This work intends to test a therapeutical total body irradiation (TBI) model as conditioning to bone marrow transplantation. With the purpose of evaluating the applicability of several biological indicators in accidental overexposures, a study was carried out in 46 patients undergoing TBI receiving doses between 10 Gy and 12 Gy. The following parameters were assessed: lipo peroxyde plasmatic levels (TBARS) and total plasma antioxidant activity, reticulocyte maturity index (RMI) and charges in lymphocyte subpopulations. These data suggest that TBARS could provide an useful evolutive indicator in accidental overexposed patients and RMI is an early indicator of bone marrow recovery after radioinduced aplasia

    2017-09-01

    Full Text Available Accidental tooth avulsion is a grievous injury and common among the children. Management of avulsed tooth within alveolar socket by reimplantation becomes a challenge for the clinician due to extraoral time and media of transportation. Although the long-term prognosis of reimplantation is poor, the time during which the tooth remain within the arch will guide the development of alveolar bone completely. Moreover, reimplantation will maintain anatomical, functional and esthetic rehabilitation of the patient. In this case report, we present a case of accidental avulsion where teeth were gently rinsed of any debris and placed in normal saline during the examination and preparation of the reimplantation sockets. The teeth were then reimplanted, functionally splinted followed by endodontical treatment. After 12 months follow-up the periodontal space was healed perfectly without any resorption or ankylosis.

    Full Text Available Background: Successful extraction of third molars depends on preoperative diagnosis and planning. Gold standard preoperative examinations are performed through computed tomography, decreasing risks and avoiding potential accidents. The present report highlights the value of preoperative examinations in face of accidentally displaced third molars. Methods: An 18-years-old female patient underwent a third mandibular molar extraction with a general dentist. Accidentally, the mandibular left third molar was displaced into the sublingual space, making necessary a second surgical step. The surgery was interrupted and the patient was referred to an expert in maxillofacial surgery. Results: After 21 days awaiting an asymptomatic health status, the second surgical step was successfully performed using multislice computed tomography as preoperative imaging guide. Conclusions: The present case report highlights the clinical usefulness of imaging planning and informed consents in face of legal and ethic potential complaints.

    Marine governance of oil transportation is complex. Due to difficulties in effectively monitoring procedures on vessels en voyage, incentives to save costs by not following established regulations on issues such as cleaning of tanks, crew size, and safe navigation may be substantial. The issue of problem structure is placed in focus, that is, to what degree the specific characteristics and complexity of intentional versus accidental oil spill risks affect institutional responses. It is shown that whereas the risk of accidental oil spills primarily has been met by technical requirements on the vessels in combination with Port State control, attempts have been made to curb intentional pollution by for example increased surveillance and smart governance mechanisms such as the No-Special- Fee system. It is suggested that environmental safety could be improved by increased use of smart governance mechanisms tightly adapted to key actors' incentives to alter behavior in preferable directions

    Aluminum phosphide is one of the commonest poisons encountered in agricultural areas, and manner of death in the victims is often suicidal and rarely homicidal or accidental. This paper presents an unusual case, where two humans (owner and housemaid) and eight dogs were found dead in the morning hours inside a room of a house, used as shelter for stray dogs. There was allegation by the son of the owner that his father had been killed. Crime scene visit by forensic pathologists helped to collect vital evidence. Autopsies of both the human victims and the dogs were conducted. Toxicological analysis of viscera, vomitus, leftover food, and chemical container at the crime scene tested positive for aluminum phosphide. The cause of death in both humans and dogs was aluminum phosphide poisoning. Investigation by police and the forensic approach to the case helped in ascertaining the manner of death, which was accidental. © 2015 American Academy of Forensic Sciences.

    Accidental cut-throat injuries are extremely rare and usually involve a sharp-edged weapon. In this paper, two cases of a cut-throat wound to two auto-rickshaw drivers are presented where the broken windshield of the auto-rickshaws was responsible for the wounds. In both the cases, fatal incised wounds were present over the neck, cutting the soft tissue along with the major vessels. The death occurred due to exsanguination caused by neck-vessel injury in one case and trachea along with neck-vessel injury in the second case. Although the wounds on the neck initially suggested homicide, they were found to have occurred accidentally as a result of a road traffic accident involving a head-on collision of auto rickshaws. The injuries were inflicted by the shattered glass of the windshield.

    Full Text Available Acute toxicity is a frequent but avoidable cause of morbidity and mortality in children especially in developing countries, including India. Present study assesses their pattern with relation to different age groupings. This retrospective study was conducted among all hospitalised paediatric victims of acute accidental poisoning at the King George Medical University; Lucknow during 2010 -11. Their history, baseline characteristics, clinical course and outcome was studied. Most children were male of less than three years with 4% overall mortality. Kerosene oil was implicated in most cases. Childhood poisoning is commonest during 1-3 years with a male preponderance. Household poisons; especially kerosene oil was responsible for most cases which was consumed accidentally. Parents must be educated and warned to keep these toxic ingredients safely in suitable containers and out of reach of their beloved children.

    Accidental marine oil spill pollution can result in severe environmental, ecological, economic and other consequences. This paper discussed the model of Marine Oil Spill Risk Mapping (MOSRM), which was constructed as follows: (1) proposing a marine oil spill risk system based on the typical marine oil spill pollution accidents and prevailing risk theories; (2) identifying suitable indexes that are supported by quantitative sub-indexes; (3) constructing the risk measuring models according to the actual interactions between the factors in the risk system; and (4) assessing marine oil spill risk on coastal city scale with GIS to map the overall risk. The case study of accidental marine oil spill pollution in the coastal area of Dalian, China was used to demonstrate the effectiveness of the model. The coastal areas of Dalian were divided into three zones with risk degrees of high, medium, and low. And detailed countermeasures were proposed for specific risk zones.

    Full Text Available Aim: Carbon monoxide (CO is often referred to as the “silent killer” because its victims cannot see it, smell it or taste it. CO is responsible for a large percentage of the accidental poisonings and deaths reported throughout the world. CO poisoning therefore is considered a serious global health threat. The aim of the present study was to describe the cases of CO poisoning in a rural areas of Adana, Turkey between 2002 and 2015 based on data collected from incident reports. Methods: The cases of accidental CO poisoning were statistically analyzed. During that period, 74 incidents occurred and 154 people were poisoned by accidental CO poisoning. Results: The results of this analysis indicate that men and adults aged ≥65 years were more likely to die from CO poisoning than others. The number of CO poisoning cases was highest during the heating season. The majority (72% of poisoning resulting in hospitalization with a life-threatening condition or death occurred within the home. Conclusion: CO poisoning is a serious danger. People must be informed about this hazard. By educating risk groups about the dangers of CO poisoning, it is possible to save many lives as well as reduce the health risks.

    Patterns of accidental poisoning in children are changing dramatically. A five year population study (1977-81) was undertaken in urban children from Brisbane (population 1 000 000). A total of 2098 children were poisoned during this period with only one fatality, which represents a dramatic reduction in mortality. Over the past 15 years (1968-82) 13 children have died from accidental poisoning from this population, and two were murdered with drugs. A study of secular trends has indicated that peak incidence occurred in 1979, and the rate has been falling progressively since. The current age corrected rate of poisoning is 393 per 100 000 children per year (0-5 year olds). The rank order of poisons, drugs, and chemicals causing hospital admission and death is: petroleum distillates 13%; antihistamines 9%; benzodiazepines 9%; bleach and detergents 7%; and aspirin 6%. The ratio of fatalities to ingestions requiring hospital admission was calculated to give an index of a practical danger of noxious agents to which children are currently exposed and the rank order is: cardiotoxic drugs, one fatality to 25 ingestions; tricyclic antidepressants, one to 44; sympathomimetic drugs, one to 54; caustic soda, one to 68; aspirin, one fatality to 350 ingestions. Accidental poisoning of children leading to death has been reduced because patterns of drug prescriptions have changed, packaging of dangerous drugs has been made safer, and substances such as kerosene have been coloured blue.

    Interest is increasing in the development of new methodologies for accidental dose assessment, exploiting the luminescence and dosimetric properties of objects and materials which can be usually found directly on exposed subjects and/or in the contaminated area. In this work, several types of ceramics employed for dental prosthetics restoration, including both innovative materials used as sub-frames for the construction of the inner part of dental crowns (core), and conventional porcelains used for the fabrication of the external layer (veneer), were investigated with regard to their thermally and optically stimulated luminescence (TSL and OSL respectively) properties, in view of their potential application in accidental dosimetry. The sensitivity to ionizing radiation proved to strongly depend on the type and brand of ceramic, with minimum detectable dose ranging from few mGy up to several tens of mGy. A linear dose-response was observed for most of the samples. However, the luminescence signals were characterised by a significant fading, which has to be taken into account for a reliable accidental dose assessment after a radiation exposure event.

    Accidental injuries represent the most common type of traumatic event to which a youth is likely to be exposed. While the majority of youth who experience an accidental injury will recover spontaneously, a significant proportion will go on to develop Post-Traumatic Stress Disorder (PTSD). And yet, there is little published treatment outcome research in this area. This review focuses on two key issues within the child PTSD literature--namely the role of parents in treatment and the timing of intervention. The issue of parental involvement in the treatment of child PTSD is a question that is increasingly being recognized as important. In addition, the need to find a balance between providing early intervention to at risk youth while avoiding providing treatment to those youth who will recover spontaneously has yet to be addressed. This paper outlines the rationale for and the development of a trauma-focused CBT protocol with separate parent and child programs, for use with children and adolescents experiencing PTSD following an accidental injury. The protocol is embedded within an indicated intervention framework, allowing for the early identification of youth at risk within a medical setting. Two case studies are presented in order to illustrate key issues raised in the review, implementation of the interventions, and the challenges involved.

  6. Humeral fracture in non-ambulant infants - a possible accidental mechanism

    Humeral fracture in a non-ambulant infant younger than 1 year is suspicious for a non-accidental injury unless there is a credible accidental explanation. A previously unrecognised accidental mechanism was described in 1996 whereby a 5-month-old infant was rolled by a 3-year-old sibling from a prone to a supine position. To investigate the widely accepted view that an infant with limited mobility cannot sustain a fracture of the humerus by his or her own actions in the absence of the intervention of an external party. We present seven cases of non-ambulant infants between 4 and 7 months of age in whom an isolated humeral fracture was the only injury present. In each case the caregiver described the fracture occurring when the child rolled over, trapping the dependent arm, without the intervention of another party. There is no proof for this mechanism in the form of an independent witness or video recording. However, we propose that this mechanism is worthy of further consideration as a rare and unusual cause for the injury. Further study is required. (orig.)

    Among the main causes of death in our country are car accidents, drowning and accidental burns. Strangulation is a potentially fatal injury and an important cause of homicide and suicide among adults and adolescents. In children, its occurrence is usually accidental. However, in recent years, several cases of accidental strangulation in children around the world have been reported. A 2-year-old male patient was strangled in a car window. The patient was admitted to the pediatric intensive care unit with a Glasgow Coma Scale score of 8 and presented with progressive worsening of respiratory dysfunction and torpor. The patient also presented acute respiratory distress syndrome, acute pulmonary edema and shock. He was managed with protective mechanical ventilation, vasoactive drugs and antibiotic therapy. He was discharged from the intensive care unit without neurological or pulmonary sequelae. After 12 days of hospitalization, he was discharged from the hospital, and his state was very good. The incidence of automobile window strangulation is rare but of high morbidity and mortality due to the resulting choking mechanism. Fortunately, newer cars have devices that stop the automatic closing of the windows if resistance is encountered. However, considering the severity of complications strangulated patients experience, the intensive neuro-ventilatory and hemodynamic management of the pathologies involved is important to reduce morbidity and mortality, as is the need to implement new campaigns for the education of parents and caregivers of children, aiming to avoid easily preventable accidents and to optimize safety mechanisms in cars with electric windows.

    Presence of accidental characteristics on footwear strengthens the linkage of a given piece of footwear to a footwear impression left at a crime-scene. Thus an understanding of rate of appearance and disappearance of these characteristics is of importance. Artificial cut-marks, 1-3mm in depth, were cut into outsoles of 11 pairs of athletic shoes. Loss of these cut-marks and acquisition of new accidental characteristics/wear patterns were monitored over a seven-week time-span. Feature-vector methods were used to acquire multivariate data on wear/acquisition rates. A repeatability study indicated the feature vector method could detect small differences among shoes relative to measurement uncertainty. The shoes displayed a strong retention of artificial cut-marks over the study interval. Net rate of wear was 0.1% of the textured area of the shoe per week, predominantly in the heel and ball area. Results indicate accidental characteristics can reasonably be expected to persist over time. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Unintentional injuries are the leading cause of death in children around the world and are an under-recognized public health problem in the United States. The purpose of this study was to highlight the nature of the problem in South Dakota and outline interventions that have been successful in reducing childhood injuries in other states. This quantitative retrospective study examined mortality files in South Dakota for children birth to 19 years of age who died between January 1, 2000 to December 28, 2007. Although the number of deaths declined considerably from 2006 to 2007, South Dakota had the second-highest rate in the nation of childhood unintentional injury deaths from all causes between 2000-2005. The majority of deaths occurred in males and were associated with transportation-related deaths. Suffocation was the leading cause of death for newborns to age 1 year. Childhood accidental death in South Dakota is clearly a critical public health problem. Intervention efforts to reduce deaths from unintentional injuries amongst children should be targeted as the leading causes of accidental death for specific age groups and American Indian youth. Physicians, health educators and policymakers must play a role in prevention targeting the high-risk groups in addition to advocating for policy changes to protect childhood safety. More stringent child restraint laws, graduated driving laws, smoking cessation programs for parents, creation of safer sleep environments and further investigation of why a high proportion of American Indian children die accidentally in South Dakota are all warranted.

    After a presentation of the process which resulted in the setting up of an investigation aimed at testing recommendations for post-accidental management, this report indicates the objectives of this investigation: to study the application of recommendations made by the CODIR-PA (Management Committee - Post-Accidental Management) to the operators of the milk sector, and to define an action plan to carry on and resume production. According to the adopted methodology, the study comprised two phases. The first one comprised an analysis of applications in the milk sector, the study of operational consequences on a zoning proposed by the CORDI-PA on the milk sector and on milk products, and the study of the acceptability and feasibility of considered options. The second phase addressed the elaboration of an action plan to carry on and resume the activity. While identifying and assessing the various risks, it identified critical issues for carrying on or resuming milk production in a contaminated territory, and defined an action plan to implement by anticipation or in the post-accidental situation

  17. Nuclear energy: benefits versus risks

    International Nuclear Information System (INIS)

    Jordan, W.H.

    1975-01-01

    Of the benefits of nuclear power three are described briefly. 1. It offers virtually an inexhaustible supply of cheap electricity, so the real reason for its installation in the U.S. (80 nuclear power plants on order and 15 in operation) is to save money. (2) Nuclear power would offer a chance to clean up the atmosphere; it has been observed that the carbon dioxide concentration in the atmosphere is increasing at about 2 percent per decade, a change that may have implications for long-term effects on climate. (3) Power reactors will undoubtedly be the major producers of radioisotopes in the future; estimates of the benefits of these isotopes are of the order of $1000 million a year from such applications as fluid flow measurements, thickness gages, leak detection, well logging, deformation determinations, agricultural application, biological applications, and in medicine. Risks of operating nuclear power plants can be classified as: thermal pollution of the rivers and lakes; low level release of radioactivity into the air and ground waters caused by the normal operation of nuclear power and reprocessing plants; and the accidental release of large amounts of radioactivity. These risks are put in perspective by comparing them with common risks that man accepts daily--transportation, cigarette smoking, mountain climbing, etc.-- after which nuclear power seems not so risky after all

    Iodine is one of the fission products which vaporizes in a complex chemical medium and can be transported under different gaseous forms in the PWR primary coolant system during a severe nuclear accident. The 'CHIP' analytical program has been implemented to study in a first time, the quaternary complex systems of the type Cs-I-O-H. In this system, the CsOH(l or s) vaporization is an important element. A study by high temperature mass spectrometry shows that the vapor species are the CsOH(g), its dimers Cs{sub 2}O{sub 2}H{sub 2}(g) and its trimers Cs{sub 3}O{sub 3}H{sub 3}(g). For this last specie, no thermodynamic determination has been done until today. The quantitative exploitation of the vapor pressures leads to the determination of the dimerization enthalpy reaction: (CsOH){sub 2}(g)=2 CsOH(g) {delta}H(average)(298.14 K)136.5 {+-} 3.85 kJ.mol{sup -1} (calculated with the third thermodynamic law).

    1982-01-01

    Safety is the major public issue to be resolved or accommodated if nuclear power is to have a future. Probabilistic Risk Analysis (PRA) of accidental releases of low-level radiation, the spread and activity of radiation in populated areas, and the impacts on public health from exposure evolved from the earlier Rasmussen Reactor Safety Study. Applications of the PRA technique have identified design peculiarities in specific reactors, thus increasing reactor safety and establishing a quide for evaluating reactor regulations. The Nuclear Regulatory Commission and reactor vendors must share with utilities the responsibility for reactor safety in the US and for providing reasonable assurance to the public. This entails persuasive public education and information that with safety a top priority, changes now being made in light water reactor hardware and operations will be adequate. 17 references, 2 figures, 2 tables

    [figure removed for brevity, see original site] Figure 1 (Click on image for larger view) This image, acquired by the Mars Exploration Rover Spirit's panoramic camera on the 53rd martian day, or sol, of the rover's mission, struck science and engineering teams as not only scientifically interesting but remarkably beautiful. The large, shadowed rock in the foreground is nicknamed 'Sandia' for a mountain range in New Mexico. An imposing rock, 'Sandia' is about 33 centimeters high (1 foot) and about 1.7 meters (5.5 feet) long.Figure 1 above is a lightened version of the more artistic image above.The combination of the rover's high-resolution cameras with software tools used by scientists allows the minute details on martian targets to be visualized. When lightened, this image reveals much about the pictured rocks, which the science team believes are ejected material, or ejecta, from the nearby crater called 'Bonneville.' Scientists believe 'Sandia' is a basaltic rock that landed on its side after being ejected from the crater. The vertical lines on the side of the rock facing the camera are known by geologists as 'flow banding' and typically run horizontally, indicating that 'Sandia' is on its side. What look like small holes on the two visible sides of the rock are called vesicles; they were probably once gas bubbles within the lava.The lighting not only makes for an artistic image, it helps scientists get a virtual three-dimensional feel for target rocks. Observations taken at different times of day, as shadows move and surface texture details on target rocks are revealed, are entered into modeling software that turns a two-dimensional image into a three-dimensional research tool.Many smaller rocks can be seen in the background of the image. Some rocks are completely exposed, while others are only peeking out of the surface. Scientists believe that two processes might be at work here: accretion, which occurs when winds deposit material that slowly buries many of the rocks; and deflation, which occurs when surface material is removed by wind, exposing more and more of the rocks.

    1981-01-01

    Mathematical models have been used to assess potential impacts of radioactivity releases during all phases of our country's development of nuclear power. Experience to date has shown that in terms of potential dose to man, the most significant releases of radioactivity from nuclear fuel cycle facilities are those to the atmosphere. Our ability to predict atmospheric dispersion will, therefore, ultimately affect our capability to understand and assess the significance of both routine and accidental discharges of radionuclides. Assessment of potential radiological exposures from postulated routine and accidental releases of radionuclides from the fast-breeder reactor will require the use of atmospheric dispersion models, and the design, siting, and licensing of breeder reactor fuel cycle facilities will be influenced by the predictions made by these models

    2011-01-01

    Full Text Available Ingestion of instruments is a potential complication that can occur during dental procedures. We report a case of accidental ingestion of an endodontic barbed wire broach during root canal treatment and its subsequent retrieval by endoscopic methods. Although prevention is the best approach, proper management of such an event is also crucial. The objective of this report is to draw attention to the potentially serious complications that can occur if preventive techniques are not practised, and to discuss the accepted guidelines for management of such an event.

  2. A model of neutrino mass and dark matter with an accidental symmetry

    2015-06-01

    Full Text Available We present a model of radiative neutrino mass that automatically contains an accidental Z2 symmetry and thus provides a stable dark matter candidate. This allows a common framework for the origin of neutrino mass and dark matter without invoking any symmetries beyond those of the Standard Model. The model can be probed by direct-detection experiments and μ→e+γ searches, and predicts a charged scalar that can appear at the TeV scale, within reach of collider experiments.

  4. Indications of hematopoietic stem cell transplantations and therapeutic strategies of accidental irradiations

    International Nuclear Information System (INIS)

    2003-01-01

    Produced by a group of experts, this document first discusses the issue of accidental irradiations in terms of medical management. They notably outline the peculiar characteristics of these irradiations with respect to therapeutic irradiations. They agreed on general principles regarding casualty sorting criteria and process, and their medical treatment (systematic hematopoiesis stimulation, allogeneic transplantation of hematopoietic stem cells). They discuss some practical aspects of these issues: casualty sorting within a therapeutic perspective (actions to be performed within 48 hours), therapeutic strategies (support therapy, use of cytokines, and therapy by hematopoietic stem cell transplant). They state a set of recommendations regarding the taking into care and diagnosis, therapeutic strategies, research perspectives, and teaching

    This work represent a guide for the treatment of accidental intakes of radionuclides. The different phases of radioactive contamination, the transfer and non-transfer of radioisotopes, the general principles in the treatment of internal contamination and the follow-up are determined. The in vivo monitoring and the evaluation of activity level are specified in this document. The applied treatment depends on the via of intake, that is: inhalation, ingestion, and through skin. The decontamination procedures that reduce the radionuclide transfer are specified. The different drugs, used to enhance radionuclides elimination, are enumerated in this work. Considerations about the iodine prophylaxis in radiologic als accidents are considered. (author)

    The computer program UFOTRI can be used for assessing the impact of accidental released tritium in the two chemical forms tritiated water vapour and tritium gas. By applying UFOTRI to potential European sites for ITER, it could be demonstrated that the main goal, the nonevacuation criteria, is fulfilled for the present release limits. Contributions in international studies together with the re-evaluation of experimental data showed that the plant sub-model as well as the soil sub-model are areas for further improvement. (author)

    Daburon, F.; Vincent-Naulleau, S

    2001-07-01

    When a serious nuclear accident occurs, the radioisotopes of caesium are very worrying to public health. Because of their long environmental persistence, their diffusion and their solubility in natural environments, they are present in many foodstuffs. Numerous studies were undertaken during the atmospheric nuclear tests, but since the accident of Tchernobyl land Goiania, this research has been pursued anew. By using the experimental data,, this report takes stock of the knowledge on the metabolic transit of radiocaesium in domestic animals. The transfer of this radionuclide in the major foodstuffs of animal origin (milk, meat, eggs) is important and depends on the metabolism of the animal species, and in one species, the age, the physiologic state and the diet. Nevertheless, it is possible to restrict the radioactive contamination by adding to all animal feed, some additives. The methods for in vivo determination of the radioactive measurements in cattle, in laboratory or in real conditions, are discussed too. Finally, all these results are used to consider the short-, middle- and long-term management of an accidental situation. (authors)

  13. Recent and prospective developments in nuclear arsenals

    International Nuclear Information System (INIS)

    Brown, M.

    1993-01-01

    Arms controllers have long complained that the only weapons states give up in arms control negotiations are strategically insignificant weapons. This is why the United States and Soviet Union shied away from giving up much in SALT I and SALT II: each side felt that it could not significantly reduce its nuclear forces, or take any step that might give the other side an advantage. Do not be fooled: policy makers in Washington and Moscow still believe that it is important to hang on to strategically significant weapons. But, because the world has changed in fundamental ways, fewer weapons are strategically significant today. Now that extended deterrence requirements have virtually disappeared, the main reason for having nuclear weapons is to deter other nuclear powers from attacking with their nuclear weapons. There is, therefore, no compelling reason for having large nuclear forces. Given concerns about unauthorized attacks, accidental launches, and high levels of defense spending, there are good reasons for deploying smaller forces. This is why Washington and Moscow have been cutting their nuclear arsenals to levels that were unimaginable even in 1990. How far this process will go is impossible to say at this juncture. What is clear is that Washington and Moscow can - and should - make even deeper cuts in their nuclear forces. If the United States and Russia retain arsenals with thousands of nuclear weapons, Britain, France, and China - whose arsenals contain hundreds of nuclear weapons - will not join the arms reduction process. Countries that have promised to give up the nuclear weapons currently stationed on their territory - Kazakhstan, the Ukraine, and Belorussia - will be more inclined to retain them, on the grounds that nuclear weapons are seen to have strategic and political value. For the same reasons, countries on the nuclear threshold, such as India, will be more inclined to acquire nuclear weapons. If the United States and Russia retain massive nuclear

    2002-01-01

    Since 1994 the Institute for Transuranium Elements has played the leading role in Europe in the development of Nuclear Forensic Science. This is a new discipline which has developed out of necessity following the break up of the former Soviet Union and Eastern Block countries in 1989, which resulted in the emergence of a new form of illegal smuggling - that of nuclear materials. The Institute has been involved in the investigation of all the major cases of illicit trafficking involving nuclear- and nuclear-related materials in Europe from 1994, following the first major incident at Munich airport, up to the present time. Examples will be given here illustrating different types of cases: the accidental release of nuclear material into the environment, exercises carried out in cooperation with the German Federal Police (Bundeskriminalamt), and the removal of nuclear material with deliberate criminal intent

    C. Martín A Alvarado-Dulanto

    Full Text Available En Latinoamérica la información del pronóstico de pacientes con enfermedad cerebrovascular (ECV es limitada. Por ello, se buscó determinar el pronóstico vital y funcional al año, de pacientes con debut de ECV. Se desarrolló un estudio de cohorte prospectivo, con seguimiento al año a pacientes con primer evento cerebrovascular reclutados en el servicio de medicina de un hospital nacional. Se recolectó datos sociodemográficos, antecedentes patológicos e información del evento. Se halló proporciones de mortalidad, diferencias entre subgrupos y se comparó la funcionalidad inicial y al año. Se incluyó 101 pacientes, 20,8% falleció durante el seguimiento, encontrándose mayor mortalidad en los mayores de 65 años y en aquellos severamente discapacitados tras el evento. La funcionalidad no mejoró al año. Se concluye que uno de cinco pacientes que debuta con ECV fallece al año, con mayor mortalidad en ancianos y en pacientes gravemente discapacitados. Es pertinente crear un sistema de seguimiento y soporte para prevenir evolución desfavorable en pacientes que sufren ECV

    Precisamente, la primera actuación de los comisarios iba a poner reparos a determinadas partidas con Hacienda, motivadas por el negocio fundacional de las provisiones. La evaluación entonces de la situación del Banco refleja un faltante de capital y se propone destinar a su saneamiento la totalidad del beneficio del ejercicio. Sometida esta decisión a los accionistas, acuerdan no recibir dividendo alguno, dedicándolo a la reconstitución del capital, manteniendo así el principio de prudencia, tras esgrimirse poderosas razones. Con nuevos directores en 1790, aunque se incrementa la evaluación del defecto en el capital, se rompe el principio de prudencia, anulando las razones que soportaron la decisión del año precedente, y se reparte un dividendo del 5%. Esta decisión quedaba soportada por unas expectativas que ya existían el año anterior y que no permitían reducir la fuerte incertidumbre existente. Tres años después el Rey indemnizará al Banco en cantidad suficiente cubriendo, finalmente, tal desequilibrio. Durante ese tiempo el establecimiento siguió repartiendo dividendos, perseverando en el camino de haber quebrado el principio de prudencia antes sentado y en contra del buen crédito del Banco.

Esta sólo puede lograrse sobre la base de la implementación de políticas que permitan que las comunidades, a partir de los conocimientos adquiridos y la infraestructura lograda, puedan realizar futuras actividades alternativas luego de agotados los yacimientos. Se valora la posibilidad de un tipo de desarrollo que proteja el medio ambiente a través de compensaciones, las cuales pueden ser logradas por dos vías: el análisis de los impactos positivos que genera la minería sobre el medio ambiente, y la compensación de los impactos irreversibles. Se proponen las actividades alternativas que se desarrollarían en el territorio minero, llegado el momento del cierre, ya sea temporal, progresivo o definitivo, lo cual permite que los decisores gubernamentales cuenten con las herramientas necesarias para lograr el desarrollo de la región

    Full Text Available Abstract Background Considerable indirect costs are incurred by time taken off work following accidental injuries. The aim of this study was to predict return to work following serious accidental injuries. Method 121 severely injured patients were included in the study. Complete follow-up data were available for 85 patients. Two weeks post trauma (T1, patients rated their appraisal of the injury severity and their ability to cope with the injury and its job-related consequences. Time off work was assessed at one (T2 and three years (T3 post accident. The main outcome was the number of days of sick leave taken due to the accidental injury. Results The patients' appraisals a of the injury severity and b of their coping abilities regarding the accidental injury and its job-related consequences were significant predictors of the number of sick-leave days taken. Injury severity (ISS, type of accident, age and gender did not contribute significantly to the prediction. Conclusions Return to work in the long term is best predicted by the patients' own appraisal of both their injury severity and the ability to cope with the accidental injury.

    1998-07-01

    To determine the change in accidental needlestick rates in the Phlebotomy Service at Mayo Clinic Rochester and to identify safety practices implemented from 1983 through 1996. We retrospectively reviewed yearly Phlebotomy Service accidental needlestick rates from 1983 through 1996. Interviews were conducted with representatives of the Infection Control Committee and the management team for the Phlebotomy Service, and minutes of meetings of these two groups were reviewed to identify implemented safety improvements that may have had an effect on accidental needlestick exposures. Accidental needlestick exposures in the Phlebotomy Service declined from a high of 1.5/10,000 venipunctures to 0.2/10,000 venipunctures. Several safety improvements were made during that time, including the implementation of a one-handed recapping block, change to single-use evacuated tube holders, increased number and improved locations of disposal containers for needles, implementation of resheathing needles and retractable capillary puncture devices, discontinuation of the practice of changing needles before inoculation of blood culture bottles, increased emphasis on safety for new and experienced phlebotomists, and improved exposure reporting tools. We believe that the decrease in our accidental needlestick exposure rate is correlated with the changes in education, practices, and products that we have implemented.

We drew on the theoretical-methodological references of Fishbein & Ajzen and Maslow's theory. Fifty health care workers were evaluated using an attitudes questionnaire and a needs and motivations instrument. The research verified differences between answers by health care workers who had never suffered accidents and those who had already experienced accidental exposure to blood. Health care workers did their work activities motivated by the need for self-fulfillment and valued their own performance when they were able to meet the patients' emotional needs. Among health professionals who had never experienced accidental exposure to blood, the predominant beliefs was that patients feel remorse over having expose themselves to HIV. Accidental exposure to blood raises difficulties in personal life. Technical aspects are also associated with the possibility of accidental exposure to blood.

    The objective of this study consists in evaluating the sensitivity of the first part of the die grass-milk with respect to an accidental radioactive discharge. We want to know if a single uniform deposit would involve a contamination of the grazing grass identical on the scale of the own territory. The study was based on the A.S.T.R.A.L. model, a computer code developed by the I.R.S.N. which makes it possible to evaluate the transfer of the radionuclides in the terrestrial food chain following an accidental atmospheric emission. The way of transfer of A.S.T.R.A.L. on which the study focused is the transfer of the deposit to milk, via the grazing grass ingestion. The sensitivity of this way of transfer relies on several parameters: captation, yield, cows food rates and dates of setting to grass. Methodology thus consisted in regionalizing these parameters. The software S.T.I.C.S. developed by the I.N.R.A. of Avignon was then used. This model proposes a daily follow-up of the leaf area index which has been correlated with captation and with the production of fresh biomass (yield). (authors)

Las tendencias sugieren que las tasas de mortalidad por causas externas para los viejos no acompañaron los alarmantes niveles de los adultos. Para los añosos, los niveles ascendieron ligeramente en el país para los hombres y disminuyó para las mujeres, y fueron los accidentes de vehículos y caídas accidentales las causas más importantes. El análisis multivariado apunta marcadas variaciones geográficas en las tendencias de las tasas de mortalidad que reflejan diferencias sociales y económicas entre los estados.

    The authors present theoretical calculations of the thermal conductivity for the accidental degeneracy and enlarged symmetry group models that have been proposed to explain the phase diagram of UPt 3 . The order parameters for these models possess point nodes or cross nodes, reflecting the broken symmetries of the ground state. These broken symmetries lead to robust predictions for the ratio of the low-temperature thermal conductivity for heat flow along the c axis and in the basal plane. The anisotropy of the heat current response at low temperatures is determined by the phase space for scattering by impurities. The measured anisotropy ratio, κ c /κ b , provides a strong constraint on theoretical models for the ground state order parameter. The accidental degeneracy and enlarged symmetry group models based on no spin-orbit coupling do not account for the thermal conductivity of UPt 3 . The models for the order parameter that fit the experimental data for the c and b directions of the heat current are the 2D E 1g and E 2u models, for which the order parameters possess line nodes in the ab-plane and point nodes along the c axis, and the A 1g circle-plus E 1g model of Zhitomirsky and Ueda. This model spontaneously breaks rotational symmetry in the ab-plane below T c2 and predicts a large anisotropy for the ab-plane heat current

  12. Accidental pollution in the ocean: besides crude oil, chemicals and other spills

    Accidental pollution of the seas is usually illustrated by the shipwreck of tankers carrying crude oil. We must look beyond this image since such accidents spill substances other than petrochemicals. We need but mention the Levoli Sun's accident near the Cotentin peninsula, France, one year after the Erika went down. And what about spills of agricultural and food products? An accidental spill as apparently harmless as wheat might have serious effects on not just the environment but also human health. In all cases, two major series of questions crop up: 1) Is it necessary to intervene? If so, are we able to? And if we can, how to fight against spills? 2) What are the short- and long-term effects on the environment and on all human activities related to the sea (fishing, fish-farming, salt production, tourism, salt-water cures, etc.)? These two questions have a common denominator: the need to know how spilled products react. This knowledge conditions both the operational response for fighting against pollution and the assessment of the impact on the maritime environment. (author)

    Full Text Available Paracetamol is one of the most commonly used analgesics and antipyretics available without limits as preparations of the OTC group (over the counter drugs. Overdose and poisoning with this drug always brings about the risk of acute hepatic failure. The objective of the study was a retrospective evaluation of patients hospitalized in the Paediatric Clinic during the period 2004–2012 due to poisoning with paracetamol.The analysis covered 44 patients hospitalized in the Paediatric Clinic during 2004–2012 due to poisoning with paracetamol. Patients were divided into three groups: intentional poisonings, accidental poisonings, and drug overdose.During the period of the study, 44 patients aged 2.1–17.1, poisoned with paracetamol, were hospitalized. Among these patients there were 30 (68.2% cases of intentional poisonings, 10 (22.7% of accidental poisonings, and only 4 patients (9.1% were children hospitalized after a paracetamol overdose. The majority of patients in all groups were females (93.3%.Paracetamol intoxication may occur after exceeding a single allowable dose, in the case of intentional poisoning, more rarely after exceeding the daily dose, in the case of intense pain complaints, or in the treatment of persistent fever.Based on the analysis performed, an increase was observed in the frequency of poisoning with paracetamol, especially intentional poisoning. Unlimited access to paracetamol as an OTC drug should be reconsidered.

  14. Postprocessing of Accidental Scenarios by Semi-Supervised Self-Organizing Maps

    Full Text Available Integrated Deterministic and Probabilistic Safety Analysis (IDPSA of dynamic systems calls for the development of efficient methods for accidental scenarios generation. The necessary consideration of failure events timing and sequencing along the scenarios requires the number of scenarios to be generated to increase with respect to conventional PSA. Consequently, their postprocessing for retrieving safety relevant information regarding the system behavior is challenged because of the large amount of generated scenarios that makes the computational cost for scenario postprocessing enormous and the retrieved information difficult to interpret. In the context of IDPSA, the interpretation consists in the classification of the generated scenarios as safe, failed, Near Misses (NMs, and Prime Implicants (PIs. To address this issue, in this paper we propose the use of an ensemble of Semi-Supervised Self-Organizing Maps (SSSOMs whose outcomes are combined by a locally weighted aggregation according to two strategies: a locally weighted aggregation and a decision tree based aggregation. In the former, we resort to the Local Fusion (LF principle for accounting the classification reliability of the different SSSOM classifiers, whereas in the latter we build a classification scheme to select the appropriate classifier (or ensemble of classifiers, for the type of scenario to be classified. The two strategies are applied for the postprocessing of the accidental scenarios of a dynamic U-Tube Steam Generator (UTSG.

    Full Text Available Here, authors present a review on clinical presentation and management of exposure of phosgene gas after reviewing the literature by searching with keywords phosgene exposure on Google, Cochrane, Embase and PubMed with a background of experience gained from 10 patients who were admitted to our institute after an accidental phosgene exposure in February 2011 nearby a city in India. Phosgene is a highly toxic gas, occupational workers may have accidental exposure. The gas can also be generated inadvertently during fire involving plastics and other chemicals and solvents containing chlorine, which is of concern to emergency responders. Phosgene inhalation may cause initially symptoms of respiratory tract irritation, patients feel fine thereafter, and then die of choking a day later because of build up of fluid in the lungs (delayed onset non-cardiogenic pulmonary edema. Phosgene exposure is associated with significant morbidity and mortality. Patients with a history of exposure should be admitted to the hospital for a minimum of 24 h for observation because of the potential for delayed onset respiratory failure and acute respiratory distress syndrome.

    The purpose of this study was to examine US accidental poisoning death rates by demographic and geographic factors from 1979 to 2014, including High Intensity Drug Trafficking Areas. Crude and age-adjusted death rates were formed for age group, race, sex, and county for accidental poisonings (ICD 9th revision: E850-E869; ICD 10th revision: X40-X49) from 1979 to 2014 using the Mortality and Population Data System housed at the University of Pittsburgh. Rate ratios were calculated comparing rates from 2014 to 1979, overall, by sex, age group, race, and county. Joinpoint regression detected changes in trends and calculated the average annual percentage change (AAPC) as a summary measure of trend. Drug poisoning mortality rates have risen an average of 6% per year since 1979. Increases are occurring in all ages 15+, and in all race-sex groups. HIDTA counties with the highest mortality rates were in Appalachia and New Mexico. Many of the HIDTA border counties had lower rates of mortality. The drug poisoning mortality epidemic is continuing to grow. While HIDTA resources are appropriately targeted at many areas in the US most affected, rates are also rapidly rising in some non-HIDTA areas. Copyright © 2016 Elsevier Inc. All rights reserved.

    Accidental inoculation of humans with veterinary vaccines can lead to early and late complications. The aim of our study is to describe these complications and their risk factors. Prospective observational study conducted from 2007 to 2014 at Angers University Hospital's Poison Control Centre. The endpoints examined were: early and late locoregional complications, surgical treatment, and absence from work. The statistical analysis was based on a multivariate analysis. The presence of mineral oil adjuvants, the injection of the vaccine under pressure and injection in joint and tendon of the hand significantly increased early locoregional complications and surgery but only the presence of mineral oil adjuvant increased significantly late locoregional complications at one month. Absence from work is significantly correlated to the site of injection and the presence of mineral oil adjuvant. It is important to know about the contents of the veterinary vaccine in order to anticipate early and late complications that may arise (particularly due to the presence of mineral oil adjuvants). Special attention must also be given do the site of injection. We think that any accidental injection of veterinary vaccine into humans, especially those containing mineral oils, must lead to an early medical consultation. This must also be indicated on the product.

    Attention Deficit Hyperactivity Disorder (ADHD) is a frequent neurodevelopmental disorder that increases accidental risk. Recent studies show that some patients with ADHD can also suffer from excessive daytime sleepiness but there are no data assessing the role of sleepiness in road safety in patients with ADHD. We conducted an epidemiological study to explore sleep complaints, inattention and driving risks among automobile drivers. From August to September 2014, 491186 regular highway users were invited to participate in an Internet survey on driving habits. 36140 drivers answered a questionnaire exploring driving risks, sleep complaints, sleepiness at the wheel, ADHD symptoms (Adult ADHD Self-Report Scale) and distraction at the wheel. 1.7% of all drivers reported inattention-related driving accidents and 0.3% sleep-related driving accidents in the previous year. 1543 drivers (4.3%) reported ADHD symptoms and were more likely to report accidents than drivers without ADHD symptoms (adjusted OR = 1.24, [1.03-1.51], p 15) versus 3.2% of drivers without ADHD symptoms and 20.5% reported severe sleepiness at the wheel versus 7.3%. Drivers with ADHD symptoms reported significantly more sleep-related (adjusted OR = 1.4, [1.21-1.60], p attentional deficits and sleepiness at the wheel in these drivers. Road safety campaigns should be improved to better inform drivers of these accidental risks.

    Highlights: • This paper presents transient CFD analyses on the cooling channels of the DEMO HCPB FW for accidental scenarios LOCA and LOFA. • In both LOCA & LOFA, the wall temperature increases quickly to an unacceptable level within seconds. • If the coolant flow rate is maintained at a half of nominal value in case of LOFA (partial LOFA), the wall temperature rises much slower, but will still leads to a damage of structure within minutes. • The simulated heat transfer coefficients were compared with empirical correlations. - Abstract: Helium Cooled Pebble Bed (HCPB) blanket concept is one of the DEMO (Demonstration Power Plant) blanket concepts running for the final DEMO design selection. In this paper, transient analyses on the cooling channels of the FW are carried out by means of CFD simulations for the selected accidental scenarios loss-of-coolant-accident (LOCA) and loss-of-flow-accident (LOFA). ANSYS-CFX is used for the simulations. The simulation results help to understand how fast the temperature of the FW can increase and what is the time window that is available until the temperature of the structural material reaches the design limit in order to be able to define a suitable protection strategy for the system. In view of later developments of the models, the heat transfer coefficients calculated with CFD are compared with the values predicted by two widely used correlations for turbulent pipe flows.

    The recent expansion of biocontainment laboratory capacity in the United States has drawn attention to the possibility of occupational exposures to BSL-3 and -4 agents and has prompted a reassessment of medical management procedures and facilities to deal with these contingencies. A workshop hosted by the National Interagency Biodefense Campus was held in October 2007 and was attended by representatives of all existing and planned BSL-4 research facilities in the U.S. and Canada. This report summarizes important points of discussion and recommendations for future coordinated action, including guidelines for the engineering and operational controls appropriate for a hospital care and isolation unit. Recommendations pertained to initial management of exposures (ie, immediate treatment of penetrating injuries, reporting of exposures, initial evaluation, and triage). Isolation and medical care in a referral hospital (including minimum standards for isolation units), staff recruitment and training, and community outreach also were addressed. Workshop participants agreed that any unit designated for the isolation and treatment of laboratory employees accidentally infected with a BSL-3 or -4 pathogen should be designed to maximize the efficacy of patient care while minimizing the risk of transmission of infection. Further, participants concurred that there is no medically based rationale for building care and isolation units to standards approximating a BSL-4 laboratory. Instead, laboratory workers accidentally exposed to pathogens should be cared for in hospital isolation suites staffed by highly trained professionals following strict infection control procedures.

  1. Evaluation of accidental coincidences for time-differential Moessbauer-spectroscopy

    1995-01-01

    The accidental coincidences of a measuring system based on time-to-amplitude conversion are considered in some detail for the case of low starting and high stopping rates. Two types of accidental coincidences are distinguished, those carrying time information and those without time information. Neglecting any deadtime effects of the detectors, analytical expressions for the calculation of the time distribution of the random coincidences are evaluated. The analytical expressions have been confirmed by Monte Carlo simulations. The procedure is applied to time-differential Moessbauer spectroscopy in order to extract the time spectra of true coincidences. The measured spectrum in a time channel turns out to be a superposition of the true spectrum (true coincidences), a time integral spectrum (random coincidences), and a weighted superposition of true spectra of other time channels (random but time carrying information). A measurement with a single line 57 Co/Rh-source and single line K[Fe(CN) 6 ].3H 2 O-absorber with stopping rates of 1 MBq shows agreement between the theoretical time-filtered spectra and the corrected measured spectra of true coincidences.

    Full Text Available An important phase of endodontic treatment is the irrigation of the root canal system. Desirable functions of irrigation are antimicrobial activity, dissolution of necrotic tissue, and non toxicity to the periradicular tissue. Toxicity of NaOCl solution on vital tissue is still controversial. Severe complications may occur if this solution is inadvertently exposed to the oral mucosa, and it is very hazardous. The purpose of this paper is to caution dentists on the hazards of using NaOCl irrigation in endodontic treatment. A case is presented in which 2.5% NaOCl solution was accidentally streaming into the patient's throat because the irrigating needle was not securely attached to the syringe, with the result that the patient had difficulty in breathing. The patient was promptly taken to a pulmonologist, internist, and ENT. The patient was given dexamethasone 10 mg iv injection, delladryl 1 cc iv, and nebulizer with 1 ampoule of steroid, 1 ampoule of ventolin and 5 cc NaCl 3x within 24 hours, and after 24 hours the condition was increased. From this case it is concluded that the 2.5% NaOCl solution is very alkaline and irritating, resulting in deem of the larynx and plugging up of the respiratory system. Clinicians need to be cautious in using NaOCl solution to avoid endangering the patient's life.

    Scottish Nuclear has recently completed a major program of improvements to its nuclear emergency facilities. The improvements include the construction of a purpose built Off-Site Emergency Centre for each of its two power stations and the development of a computer based information management system to facilitate the rapid distribution of information on an emergency to local, regional and national agencies. A computer code has also been developed to allow the rapid assessment of the effects of any accidental release on the local population. The improvements to the emergency facilities have been coupled with changes in local and national arrangements for dealing with a civil nuclear emergency. The use of airborne surveying techniques for rapidly determining levels of deposited activity following an accident is also being examined and preliminary airborne surveys have been carried out.

    This seal which cannot be counterfeited, specially for sealing nuclear objects, e.g. fuel rods, not only makes any damage which has taken place obvious, but makes identification according to a key possible. For this purpose a minimum number of 'particles' or small bodies, which are identical but of different permeability, are fixed inside a short tube during 'loading' of the seal in a certain or an accidental sequence. The sequence of the spheres, which represents a key, can only be determined by special electromagnetic measuring equipment. On first opening the seal, this key sequence is irrevocably destroyed.

    Datura stramonium (DS) is a hallucinogenic plant that can produce anticholinergic toxicity because of its significant concentrations of toxic alkaloids, such as atropine, hyoscyamine, and scopolamine. DS grows in both rural and urban areas in Turkey. Clinical findings of toxicity are similar to those of atropine toxicity. DS abuse is common among adolescents because of its hallucinatory effects. However, accidental DS poisoning from contaminated food is very rare. Accidental poisonings are commonly seen among children. Children are more prone to the toxic effects of atropine; ingestion of even a small amount can cause serious central nervous system symptoms. Treatment is supportive; antidote treatment is given rarely. An eight-year-old male with accidental DS poisoning who presented to the Pediatric Emergency Department with aggression, agitation, delirium, and visual hallucinations is reported.

    Positron emission mammography (PEM) has begun to show promise as an effective method for the detection of breast lesions. Due to its utilization of tumor-avid radiopharmaceuticals labeled with positron-emitting radionuclides, this technique may be especially useful in imaging of women with radiodense or fibrocystic breasts. While the use of these radiotracers affords PEM unique capabilities, it also introduces some limitations. Specifically, acceptance of accidental and Compton-scattered coincidence events can decrease lesion detectability. The authors studied the effect of accidental coincidence events on PEM images produced by the presence of 18F-Fluorodeoxyglucose in the organs of a subject using an anthropomorphic phantom. A delayed-coincidence technique was tested as a method for correcting PEM images for the occurrence of accidental events. Also, a Compton scatter correction algorithm designed specifically for PEM was developed and tested using a compressed breast phantom.

    The assets and shortcomings of a well-type NaI detector and a Ge detector were examined using the Marinelli geometry, test tube geometry, and beaker geometry. Plots of the efficiency vs. energy (efficiency calibration), recorded time vs. true time (dead-time effects), and maximum activity vs. energy are reproduced. A high counting efficiency is typical of the scintillation detector in the well for the test tube geometry, particularly in the low energy range. For energies higher than 100 keV, the counting efficiency decreases because of the increasing penetration of the detector bulk by high-energy photons. For the germanium detector, the highest counting efficiency was achieved in the beaker geometry. A linear relationship exists between the calculated and measured counts at the beginning of the recorded curve for both systems. For the well-type detector the maximum detectable count rate was about 30 kcps, the linearity of the plot of the true count rate was guaranteed up to 10 kcps. Dead time correction was to be made at higher count rates. For the germanium detector the maximum detectable count rate was only about 8 kcps due to the longer dead time, the linear segment, however, was longer than for the scintillation detector. It is concluded that although the maximum detectable count rate of the germanium detector is lower, higher true activities can be detected with it owing to the lower detection efficiency. The well-type scintillation detector is advantageous for the test tube geometry. (P.A.)

    Several air dispersion models are available for prediction and simulation of the hazard areas associated with accidental releases of toxic gases. The most model packages (commercial or free of charge) include a chemical database, an intuitive graphical user interface (GUI) and automated graphical output for effective presentation of results. The models are designed especially for analyzing different accidental toxic release scenarios ("worst-case scenarios"), preparing emergency response plans and optimal countermeasures as well as for real-time risk assessment and management. Uncertainties in the meteorological input together with incorrect estimates of the source play a critical role for the model results. The research project RETOMOD (reference scenarios calculations for toxic gas releases - model systems and their utility for the fire brigade) was conducted by the Central Institute for Meteorology and Geodynamics (ZAMG) in cooperation with the Vienna fire brigade, OMV Refining & Marketing GmbH and Synex Ries & Greßlehner GmbH. RETOMOD was funded by the KIRAS safety research program at the Austrian Ministry of Transport, Innovation and Technology (www.kiras.at). The main tasks of this project were 1. Sensitivity study and optimization of the meteorological input for modeling of the hazard areas (human exposure) during the accidental toxic releases. 2. Comparison of several model packages (based on reference scenarios) in order to estimate the utility for the fire brigades. This presentation gives a short introduction to the project and presents the results of task 1 (meteorological input). The results of task 2 are presented by Stenzel and Baumann-Stanzer in this session. For the aim of this project, the observation-based analysis and forecasting system INCA, developed in the Central Institute for Meteorology and Geodynamics (ZAMG) was used. INCA (Integrated Nowcasting through Comprehensive Analysis) data were calculated with 1 km horizontal resolution and

  16. Urban "accidental" wetlands mediate water quality and heat exposure for homeless populations in a desert city

    In urban settings where humans interact in complex ways with ecosystems, there may be hidden or unanticipated benefits (services) or harm (disservices) conferred by the built environment. We examined interactions of a highly vulnerable population, the homeless, with urban waterways and wetlands in the desert city of Phoenix, Arizona, U.S.A. Climate change models project increases in heat, droughts, and extreme floods for the southwestern U.S. These projected changes pose a number of problems for sustainability and quality of future water supply, and the ability of human populations to mitigate heat stress and avoid fatalities. Urban wetlands that are created "accidentally" (by water pooling in abandoned areas of the landscape) have many structural (e.g., soils and hydrology) and functional (e.g., high denitrification) elements that mimic natural, unaltered aquatic systems. Accidental wetland systems in the dry bed of the Salt River, fed by storm and waste water from urban Phoenix, are located within economically depressed sections of the city, and show the potential for pollutant and heat mitigation. We used a mixed-method socio-ecological approach to examine wetland ecosystem functions and the ways in which homeless populations utilize Salt River wetlands for ecosystem services. Interviews and trash surveys indicated that homeless people are accessing and utilizing the wetlands as a source of running water, for sanitary and heat mitigation services, and for recreation and habitation. Environmental monitoring demonstrated that the wetlands can provide a reliable source of running water, nutrient and pathogen removal, heat mitigation, and privacy, but they may also pose a health risk to individuals coming in contact with the water through drinking or bathing. Whether wetlands provided a net benefit vs. harm varied according to site, season, and particular service, and several tradeoffs were identified. For example, heat is highest during the summer storm season

    Missing a fracture in a child on skeletal surveys for suspected non-accidental trauma can have devastating results. Double-read has the potential to improve fracture detection. However the yield of double-read is unknown. To determine the advantage of double-read versus single-read of radiographic skeletal surveys for suspected non-accidental trauma. The study was performed in two phases. In the first phase (April 2013 to September 2013), double-read was performed for all skeletal surveys obtained during weekday working hours. Because we had no new double-read findings in studies initially read as negative, we conducted a second phase (January 2014 to March 2014). In the second phase we limited double-reads to skeletal surveys found positive on the first read. At the end of this period, we retrospectively performed double-read for all initially negative skeletal surveys. We excluded follow-up skeletal surveys. The difference in discrepancy (new fracture or false diagnosis of a fracture) ratio between negative and positive skeletal surveys was evaluated using the Fisher exact test, and change in discrepancy ratio between the first and second study phases was evaluated using the stratified Cochran-Mantel-Haenszel test. Overall in the two phases, 178 skeletal surveys were performed in 178 children (67 girls) with mean age of 9 months (range 3 days to 3.7 years). Double-read found 16 discrepancies in 8/178 (4.5%) skeletal surveys. Seven of these studies showed additional fractures (n=15). In one study, an initial read of a skull fracture was read as a variant on the second read. There was a significant (P=0.01) difference between rate of disagreement in negative skeletal surveys (1/104, 1.0%) and positive skeletal surveys (7/74, 9.5%). No significant change in disagreement rate was demonstrated between the two phases of the study (P=0.59). Double-read of skeletal survey for suspected non-accidental trauma found false-negative fractures in a few cases and rarely found

    Drug errors are quite common. Many of them become harmful only if they remain undetected, ultimately resulting in injury to the patient. Errors with cytotoxic drugs are especially dangerous because of the highly toxic potential of the drugs involved. For medico-legal reasons, only 1 case of accidental iatrogenic intoxication by cytotoxic drugs tends to be investigated at a time, because the focus is placed on individual responsibility rather than on system errors. The aim of our study was to investigate whether accidental iatrogenic intoxications by cytotoxic drugs are faults of either the individual or the system. The statistical analysis of distribution and quality of such errors, and the in-depth analysis of contributing factors delivered a rational basis for the development of practical preventive strategies. A total of 134 cases of accidental iatrogenic intoxication by a cytotoxic drug (from literature reports since 1966 identified by an electronic literature survey, as well as our own unpublished cases) underwent a systematic error analysis based on a 2-dimensional model of error generation. Incidents were classified by error characteristics and point in time of occurrence, and their distribution was statistically evaluated. The theories of error research, informatics, sensory physiology, cognitive psychology, occupational medicine and management have helped to classify and depict potential sources of error as well as reveal clues for error prevention. Monocausal errors were the exception. In the majority of cases, a confluence of unfavourable circumstances either brought about the error, or prevented its timely interception. Most cases with a fatal outcome involved erroneous drug administration. Object-inherent factors were the predominant causes. A lack of expert as well as general knowledge was a contributing element. In error detection and prevention of error sequelae, supervision and back-checking are essential. Improvement of both the individual

    Full Text Available As the result of the Chernobyl NPP accident more than 200 thousand square kilometers of the European territories were contaminated by Cs-137 in the amount of above 37 kBq/m2 (1 Ci/km2 . Belorussia, Russia and Ukraine amount up to 70% of this entire affected area. More than 600 000 people were engaged in the accidental cleanup operations, 340000 were evacuated or relocated within 1986-1991. The early stage evacuation efficacy is confirmed by the absence of acute radiation syndrome among the population and by the prevented collective dose which amounts to no less than 10 000 man/Sv. The effective measure to reduce the internal radiation dose to the population at the early accidental stage was introduction of maximum tentative permissive levels of radionuclide content in the foodstuffs.Among the identified post -accident medical consequences of the Chernobyl is the radiation syndrome found in 134 emergency cleanup workers within the first 24 hours of the accident’s development. Out of that number, 28 people died within the first four months, 19 people died before 2006. The accident’s liquidators developed radiation -induced leukemia ( the attributive risk value is 45-60% . People exposed to high radiation doses display the statistically significant 18% morbidity increase of all types of solid cancers at the doses above 150 mSv. There is the statistically significant information indicating the increased amount of thyroid cancer morbidity among those who were just children and teenagers at the time of the accident. The adverse psychological consequences are accounted for not just the fear of overexposure but also for the disturbance of the habitual lifestyle especially mindful of the forced relocation.The longterm protection measures, radionuclide decay and selfcleaning of the contaminated areas resulted in the drastic reduction of the population dose in the radioactively contaminated territories. In 2015, only in some settlements of the Briansk

    Full Text Available Si se considera que Heidegger ha reflexionado permanentemente sobre el sentido que la experiencia humana de Dios puede ofrecer a la filosofía, incluso durante aquella fase de su pensamiento en la que rechazó el recurso filosófico a la experiencia de Dios, entonces se puede hablar de una continuidad de la cuestión de Dios en el pensar de Heidegger. Ahora bien, esta noción amplia de continuidad requiere un análisis más detenido. El problema es el siguiente: ¿Cómo hemos de entender el recurso afirmativo a la experiencia de Dios tras la crisis de Ser y Tiempo! ¿Es que Heidegger retomó el curso original de su pensar, del cual se había apartado durante la aventura malograda de la ontología fundamental? ¿O se trata más bien de un desarrollo sui generis surgido tras la crisis de Ser y Tiempo, que solo puede ser explicado si se tiene en cuenta el proceso mismo de crisis y transición? El presente trabajo defiende la segunda hipótesis. Se intentará mostrar que la referencia explícita a Dios y lo divino realizada por Heidegger a partir de los años treinta, más allá de toda posible vinculación retrospectiva que pudiera tener con los "orígenes teológicos", tiene una especificidad que no puede entenderse como un carácter previo a Ser y Tiempo, sino como posterior a este.If we consider that Heidegger has permanently reflected on the meaning that the human experience of God can offer philosophy, even during that phase of his thought in which he rejected the philosophical recourse to the experience of God, then we can speak of a continuity of the question of God in the Heidegger's thinking. Now, this expansive notion of continuity requires a more considered analysis. The problem can be expressed as follows: How are we to understand the affirmative recourse to the experience of God after the crisis of Beíng and Time? Is it because Heidegger took up once again the original course of his thinking, which he had set aside during his badly

  5. Parents accidentally substitute similar sounding sibling names more often than dissimilar names.

    Griffin, Zenzi M; Wangerman, Thomas

    2013-01-01

    When parents select similar sounding names for their children, do they set themselves up for more speech errors in the future? Questionnaire data from 334 respondents suggest that they do. Respondents whose names shared initial or final sounds with a sibling's reported that their parents accidentally called them by the sibling's name more often than those without such name overlap. Having a sibling of the same gender, similar appearance, or similar age was also associated with more frequent name substitutions. Almost all other name substitutions by parents involved other family members and over 5% of respondents reported a parent substituting the name of a pet, which suggests a strong role for social and situational cues in retrieving personal names for direct address. To the extent that retrieval cues are shared with other people or animals, other names become available and may substitute for the intended name, particularly when names sound similar.

    2011-01-01

    In this paper, we examine the ways that early adolescents talked, interacted, and made references to events in their individual and collective lives during photography-based focus groups about sexuality and relationships. Twenty-three participants (10 boys and 13 girls) were recruited from three urban schools participating in a comprehensive sex education impact evaluation in the Northeast. We analyzed conversational narratives that were elicited in a group process while sharing photos of important people, contexts, and situations, showcasing participants' exploration of sexuality and relationships. Our analysis revealed four main themes: (a) direct and indirect family communication about sexuality, (b) accidental and intentional Internet usage, (c) shared and contested peer knowledge, and (d) school as a direct and indirect learning context. Implications and future directions for practice, research, and policy are explored.

    2010-01-01

    To discuss the possible etiopathogenetic mechanism of inner ear damage induced by the ingestion of potassium hydroxide (KOH). We report the case of a 37-year-old patient with sudden bilateral sensorineural hearing loss after accidental ingestion of a KOH solution. The first ear, nose and throat examination disclosed only mild edema of the upper airways. He was treated in the intensive care unit and prescribed high-dose steroids, proton pump inhibitors and sucralfate for 2 weeks. Unfortunately, there was no recovery of the hearing loss, and no audiogram changes were noticed after 12 months of follow-up. After exploring the possible etiopathogenetic mechanism involved, the authors believe that in this case, a transient severe hemodynamic imbalance can actually be considered to be the most reliable explanation for the inner ear damage and subsequent onset of permanent bilateral sensorineural hearing loss.

  9. Malignant Cerebellar Edema Subsequent to Accidental Prescription Opioid Intoxication in Children

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available We present two recent cases of toddlers who developed malignant cerebellar edema subsequent to accidental ingestion of prescription opioids. Both children presented acute neurological decline, hydrocephalus, and tonsillar herniation requiring emergent ventricular drain placement, suboccipital craniectomy, and partial cerebellectomy. Together with several other reports, these cases suggest the existence of an uncommon yet severe syndrome of acute opioid-induced malignant cerebellar edema. We hypothesize that the condition results from a combination of primary opioid receptor-mediated changes in neuronal metabolism that are exacerbated by secondary hypoxic insult. If recognized promptly, this syndrome can be treated with emergent neurosurgical intervention with good clinical outcomes. These cases also illustrate the unintended consequences and innocent victims of the spiraling prescription opioid epidemic, which will likely increase in prevalence. Recognition of this syndrome by clinicians is thus critical.

    The aim of studies on iodine is to demonstrate that in the case of failure in the containment occuring after more than one day, the total quantity of iodine released would be lower or equal to 1% of the inventory of the core at the moment of the begining of the accident. The first part describes the behavior of iodine in the containment of a PWR, in the case of an important accident. The second part deals with a synthesis of the knowledge about iodine. The third part presents the inventory of the main problems not resolved concerning the chemistry of iodine and the radiolysis of iodine. Finally, the program of studies on iodine is briefly presented; its aim is to develop the knowledge about iodine in accidental situations [fr

    Exposure to firearms increased substantially after the December 2012 shooting at Sandy Hook Elementary School in Newtown, Connecticut, where 20 children and 6 adults were killed. Gun sales spiked by 3 million, on the basis of the increase in the number of background checks for firearm purchases. Google searches for buying and cleaning guns increased. We used Vital Statistics mortality data to examine whether a spike in accidental firearm deaths occurred at the same time as the greater exposure to firearms. We also assessed whether the increase in these deaths was larger in those states where the spike in gun sales per capita was larger. We find that an additional 60 deaths overall, including 20 children, resulted from unintentional shootings in the immediate aftermath of Sandy Hook.

    1983-01-01

    This report contains an assessment of the radiological impact on the Greater London population of postulated accidental releases from the Sizewell PWR. Three of the degraded core accident releases postulated by the CEGB are analysed. The consequences, conditional upon each release, are evaluated in terms of the health impact on the exposed population and the impact of countermeasures taken to limit the exposure. Consideration is given to the risk to the Greater London population as a whole and to individuals within it. The consequences are evaluated using the NRPB code MARC (Methodology for Assessing Radiological Consequences). The results presented in this report are all conditional upon the occurrence of each release. In assessing the significance of the results, due account must be taken of the frequency with which such releases may be predicted to occur.

    Animal cruelty is defined as a deliberate action that causes pain and suffering to an animal. In Brazil, legislation known as the Environmental Crimes Law states that cruelty toward all animal species is criminal in nature. From 644 domestic cats necropsied between January 1998 and December 2009, 191 (29.66%) presented lesions highly suggestive of animal cruelty. The main necroscopic finding was exogenous carbamate poisoning (75.39%) followed by blunt-force trauma (21.99%). Cats from 7 months to 2 years of age were the most affected (50.79%). In Brazil, violence is a public health problem and there is a high prevalence of domestic violence. Therefore, even if laws provide for animal welfare and protection, animals are common targets for violent acts. Within a context of social violence, cruelty toward animals is an important parameter to be considered, and the non-accidental lesions that were found are evidence of malicious actions.

    The consequences of an accidental beam loss in superconducting accelerators and colliders of the next generation range from the mundane to rather dramatic, i.e., from superconducting magnet quench, to overheating of critical components, to a total destruction of some units via explosion. Specific measures are required to minimize and eliminate such events as much as practical. In this paper we study such accidents taking the Superconducting Supercollider complex as an example. Particle tracking, beam loss and energy deposition calculations were done using the realistic machine simulation with the Monte-Carlo codes MARS 12 and STRUCT. Protective measures for minimizing the damaging effects of prefire and misfire of injection and extraction kicker magnets are proposed here

  17. Children's Intrinsic Motivation to Provide Help Themselves After Accidentally Harming Others.

    Little is known about the flexibility of children's prosocial motivation. Here, 2- and 3-year-old children's (n = 128) internal arousal, as measured via changes in pupil dilation, was increased after they accidentally harmed a victim but were unable to repair the harm. If they were able to repair (or if they themselves did not cause the harm and the help was provided by someone else) their arousal subsided. This suggests that children are especially motivated to help those whom they have harmed, perhaps out of a sense of guilt and a desire to reconcile with them. Young children care not only about the well-being of others but also about the relationship they have with those who depend on their help. © 2016 The Authors.

    Full Text Available After missing for seven days, a 34-year-old female was found with a rectal temperature of 19.8oC. Instead of attempting aggressive rewarming in the emergency department she was directly transferred to the operating room for extracorporeal rewarming. She received cardiopulmonary bypass (CPB for 66 minutes at an initial warming rate of 12oC/ hour and warmed to 36.2oC. Her postoperative course was complicated by sepsis, which eventually led to bilateral below-knee amputations after refusing antibiotics. She was discharged 22 days after admission, with full neurologic recovery. This remarkable case highlights the emerging role of CPB as the definitive therapy for severe accidental hypothermia.

    Fractures are a common finding in children and it is estimated that 2.1% of all children will suffer at least one fracture before the age of 16. With young children in particular, the question may arise if this is related to child abuse. The aim of this book is to help physicians involved in child abuse cases to interpret radiological findings in light of the forensic circumstances under which they occurred. The authors present up-to-date literature related to the mechanisms underlying non-accidental cases of trauma. In this book not only the radiological findings in child-abuse are discussed, but more importantly, these findings are analyzed from a forensic perspective. Careful attention is paid to evidence regarding reported trauma mechanisms and their clinical outcome; for example, can a fall from a couch result in a femoral fracture, and if not, where is the supporting evidence?

    Chronic exposure to chlorine gas has been shown to cause occupational asthma. Acute inhalation of chlorine is known to cause airway inflammation and induce airway nitric oxide formation. Exhaled nitric oxide may therefore be a marker of airway damage after chlorine gas exposure. After accidental chlorine gas exposure in a swimming pool, exhaled nitric oxide and pulmonary function were repeatedly measured in 18 children over a 1-mo period. Symptomatic children with impaired pulmonary function had higher nitric oxide levels on the day after the exposure compared to day 8 and day 28. Differences in exhaled nitric oxide were more pronounced at a higher exhalation flow compared to lower flow, suggesting peripheral rather than central airway damage. This was in accordance with the observed changes in pulmonary function. No changes in exhaled nitric oxide were seen in asymptomatic children. These data suggest that acute chlorine gas exposure results in a mild increase of exhaled nitric oxide in symptomatic children.
