The article discusses a study which estimated the relative risk (RR) of lung cancer death related to silicosis among French uranium miners and assesses the impact of taking account of silicotic status on the relation between exposure to radon and lung cancer adjusted on smoking. The study proved that the relation between radon and lung cancer persists after adjusting for smoking and silicosis. The study identified silicotic miners based on appraisals.

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. [ABSTRACT FROM AUTHOR]
