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.
