To support patient management of possible radiation casualties in case of a radiological or a nuclear event, the Defence Radiation Protection Service (SPRA) is able, 24 h a day, to supply intervention means in France and overseas if requested by military authorities or civilian institutions. SPRA has developed mobile laboratories for the diagnosis of internal radionuclide contamination. The mission of this mobile unit is to study health and environment risks linked to radiological hazards for exposed people: workers, soldiers and also civilians. The mobile laboratories are able to be deployed in all types of nuclear or radiological events, and give the results of analysis to physicians and authorities in a short time. The vehicles are fully equipped to detect and to survey exposure to alpha, beta and gamma emitters for the supervision of people exposed to ionising radiation, by whole body counting or analysis of biological samples. Environmental survey by analysis of wipes, soil, water, vegetation or air filters can also be achieved.
RÉSUMÉ
ABSTRACT Cosmic radiation exposure: work-place study about air-crew in the French Air-force flying on board the E-3F.This workplace study is allowed to cosmic radiation of aircraft-crews. In a first time, the work is based on measurements of the ambient dose equivalent rates on board the E-3F aircraft. These results are supplemented by measurements of individual exposure using passive and active gamma and neutrons dosemeters. Above 10 000 meters and 200 hours per year, the aircraft-crews flying on board the E-3F aircraft are likely to annually receive an effective dose higher than 1 mSv. It is therefore necessary to organize a specific radiological and medical survey of the aircraft-crews corresponding to these flight criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
