AbstractAbstract
[en] This document presents propositions for the organization of health supervision after a radiological accident of medium severity. It distinguishes short term medical care (psychological impacts, side effects of ingestion of iodine tablets, anthropo-radiometry when required, and prevention or taking into care of health problems due to massive grouping of people), and long term measures. The author indicates and discusses what health supervision will have to do: to identify health problems to be treated in priority, to assess the impact of the accident, to give elements on the application and efficiency of management actions. He also discusses and comments the various tools which health supervision will use: a health control and alert system, existing health supervision data, an adapted epidemiological investigation

AbstractAbstract
[en] The radiodermatitis is a burning of skin tissue and subcutaneous tissue in relation with ionizing radiation. In the medical practice, outside radiotherapy excluded of our study, it is observed only with acts of interventional radiology. The consequences of a radiodermatitis can be aesthetic, with appearance of a scar or a definitive alopecia, functional with loss of substance needing sometimes a remedial surgical act and finally oncologic with a risk of localised skin cancer. A radiodermatitis can appear with a radiation dose of 2 grays and its intensity worsens with the dose. Since the late 1970's about 200 cases of radiodermatitis have been reported. the most of cases have been reported between 1993 and 2000 and less than ten cases have been reported since 2000, suggesting a possible reduction of incidence explainable by a concomitant improvement of technological quality of the equipment. In order to confirm this eventual trend az feasibility study has been organised and is reported in this article. Given the results, this complication is still existing. In spite of the small number of observed cases, it is to notice that every procedures of interventional radiology are concerned. The preliminary character of this study encourages the institute of Health surveillance to work on the elaboration of a program of radiodermatitis surveillance. It could be associated to actions of improvement of the prevention and follow-up of patients, of feedback, and making easy an optimization of the practices. (N.C.)

AbstractAbstract
[en] Since the creation of the earth, its subsoil contains radioactive components at various concentrations and activities. Uranium is one of them. The common and main characteristic of all this radioactive material is its instability: during their disintegration new components appear, some of them are radioactive, others not. One of the products issued out of uranium decay is radon, a radioactive gas of natural origin. This gas may concentrate in dwellings where people spend most of their time. Radon gas represents more than one third of the total radioactive exposure of the French population. It may induce an excess of lung cancer in the exposed population: consequently surveys of radon exposure in French dwellings and its effects re currently carried on. Reducing high radon levels in dwellings is possible by using remedial actions, most of them can be easily implemented for new houses as well as by the occupants of old houses at relatively low prices.

AbstractAbstract
[en] We spend 90 per cent of our life in buildings and radon is a proven carcinogen agent. However, in France a debate is ongoing among potential stake holders as to whether radon has a public health impact or not. In the regions where radon is a potential issue, the stake is to inform the various actors (including the population) of the scientific level of evidence on the effects of radon exposure, to assess its public health impact, to target actions while at the same time giving the opportunity to those actors to assess the remaining uncertainties. This task is incumbent upon the 'Cellules interregionales d'epidemiologie' (Inter regional Epidemiology Centres). Through the synthesis of studies conducted in two French regions with a high potential for radon, this article presents the approach, its methodology, its limitations and interests in management and delineates ways of improvements. The two studies were conducted in Brittany and in Corsica on the basis of results of a terms of campaign related to indoor radon by the Institute of Radioprotection and Nuclear Safety and the Ministry of Health. The risk fraction as well as the annual number of lung cancer deaths attributable to lifelong radon exposure were estimated for crude adjusted distributions based on the B.E.I.R. VI model (biological effects of ionizing radiation), which is a reference for experts. For mean exposures of 98 Bq/m3 and of 197 Bq/m3 an attributable risk fraction of respectively 20% and 30% was observed. Results show that in regions with a real radon potential, at least 50% of the attributable risk is due to concentrations above 100 Bq/m3. When reducing exposure in case levels exceed 200 or 400 Bq/m3 to lower levels, a significant efficiency on the safety health impact in those regions is observed. On the basis of such models, policy choices could be drafted and quantified while introducing more realistic hypotheses on the main factors that can determine the success of action policies intended to reduce indoor radon levels. It would be easier to optimize policy and technical choices in terms of actions against radon. (author)

AbstractAbstract
[en] Radiodermatitis is a radio-induced and dose-dependent cutaneous lesion which appears after an accidental exposure to ionizing radiations, or an error in dose optimization. In order to have a quantitative knowledge of the cases of secondary radiodermatitis diagnosed by dermatologists, a survey has been performed among the members of a French dermatologist professional association. A questionnaire was sent to the 1450 members and 218 of them answered. Ten cases of radiodermatitis have been reported. The author discusses the implications of these results in terms of dose optimization

AbstractAbstract
[en] Technological disasters bring about psychological effects in exposed populations of various durability and intensity. This article reviews the epidemiological studies which assess psychological and psychiatric consequences of the Three Mile Island, Goieanna and Chernobyl accidents. It shows, in different accidental and cultural contexts, a statistically significant and durable increase of psychological symptoms in various exposed population groups, which points out an actual psychological distress. Diagnosed psychiatric effects are less constant, but much less studied. Most affected groups are mothers of young children, relocated persons, persons with less social support or in financial trouble. The psychological distress can further psychiatric disorders and give rise to behavioural changes towards health. More research is necessary to delineate the nature and the determinants of the observed symptoms and disorders. It implies to design better tools for the assessment of individual exposure and the diagnosis of mental health effects. (authors)

AbstractAbstract
[en] It is now obvious that there is a risk of lung cancer because of the radon exposure in houses. The domestic exposure is the second cause of the lung cancer after tobacco. It is possible to reduce the concentration in radon in houses. The domestic exposure to radon is a problem of public health that we have to manage. The question is to know to what point from a technical, economical and public health point of view. Studies about cost-efficiency should be made to better direct the political actions on radon. Two points are important to fight against bad effects of radon, the reduction of radon levels in houses and the fight against addiction to smoking. (N.C.)

AbstractAbstract
[en] The principal result of this study, in the perspective of the implementation of an epidemiological follow-up of radiological practices, is to show that the scanner and the interventional radiology, that regroup about 8% and 1.5% of the examinations number, represent respectively about 35% and 19% of the dose to the population. These examinations are in regular progression these last years. A such evaluation allows to better adapt the efforts of the epidemiological surveillance of radiological practices. Our evaluation of the situation in France in 2002 allows a comparison with the previous data registered in France but also international comparisons. The comparison of French data during the twenty last years is based, firstly, on the comparison of the number of examinations. on this period, we observe a reduction of abdomen examinations with injection of contrast product without substitution at the profit of abdomen scanner but likely at the profit of non irradiating examinations such MRI or echography. Conversely, other indications of the scanner have been developed (head and thorax). The resultant of changes in the radiological practice in term of exposure to X radiation of the population is more difficult to analyse. In addition of the number of examinations, the radiological technique has reduced the exposure. More, the coefficient of weighting used for the calculation of efficient dose have been changed in 1990 with the passage of the ICRP 26 to the ICRP 60 recommendation. The international comparisons are also a problem of method: different approaches to compare acts, values of average efficient doses by examination are referred to doses established in Great britain when the real average efficient doses by examination vary from a country to another. An European project called 'Dose Datamed' is underway to homogenize the methods of collection. The strategies of examinations uses can be different in each country. The cumulative exposure of patients should also be taken into consideration. (N.C.)

AbstractAbstract
[en] The necessity of a information gathering system allowing to globally evaluate the contribution of medical exposure to the French population exposure and to know more particularly the most irradiating practices and these ones that reach the most sensitive populations has been emphasized in the 'Vrousos' report on the priorities in radiation protection and detailed in the actions planning for the patients surveillance to ionizing radiation exposure by the general direction of nuclear safety and radiation protection. So, the Institute of radiation protection and nuclear safety and the institute of health surveillance have decided to co-ordinate their efforts to implement an observatory of medical practice in radiology. This study should allow to know the average radiation dose delivered for each act and to know the nature and frequency of these acts. for example the average radiation dose in conventional radiology has been estimated between .66 to .83 mSv by year according to the lowest or highest hypothesis. The examinations of conventional radiology would contribute to 35% of the total dose delivered to population, scanography examinations to 40% and the nuclear medicine acts and interventional radiology for 20 to 25%.

AbstractAbstract
[en] After a radiological accident, the objectives of the census are to assess the size of various populations involved, to facilitate the individual dosimetry, to give access to medical care, to allow epidemiological studies, to manage the indemnification of the victims. The census has to be done as quickly as possible before the population scatters and becomes lost to any follow-up. Population who benefit of protective actions justify active and exhaustive census. Population concerned by the accident for living close to the central justify active representative sampling joint to a passive census. During the census, collecting the exact identity and contact-numbers of the person is essential in order to be able to cross-check individual information on dosimetry, medical care, or protective action. A short questionnaire is ready to use for this purpose. The organisation concerns also the data key-boarding, its centralization, its cross-checking between sources, its conservation and its analysis. The achievement of this census will require a strong organisation of the network that it is compulsory to plan before any accident and to test in crisis exercise. (authors)
