“…Between 1956 and1982, individual annual radon exposure was estimated from ambient measurements taken in the mines combined with a detailed occupational history, including information recorded monthly about job title and worksite. After 1983, the alpha energy exposure recorded by individual dosimeters was used to measure radon exposure (Zettwoog 1981;Bernhard et al 1992). For each individual, cumulative radon exposure (CRE) was calculated as the sum of yearly exposures, from first year of exposure up to 5 y before death for cases and 5 y before death of the corresponding case for controls, which means that a minimum lag time of 5 y between exposure and death from lung cancer was adopted (National Research Council 1999).…”

A case-control study nested in the cohort of French uranium miners took smoking information into account in investigating the effect of radon exposure on lung cancer risk. This study included 100 miners who died of lung cancer and 500 controls matched for birth period and attained age. Data about radon exposure came from the cohort study, and smoking information was retrospectively determined from a questionnaire and occupational medical records. Smoking status (never vs. ever) was reconstructed for 62 cases and 320 controls. Statistical analyses used conditional logistic regression. The effect of radon exposure on lung cancer risk was assessed with a linear excess relative risk model, and smoking was considered as a multiplicative factor. Mean cumulative radon exposures were 114.75 and 70.84 Working Level Months (WLM) among exposed cases and controls, respectively. The crude excess risk of lung cancer per 100 WLM was 0.98 (95% CI: 0.18-3.08%). When adjusted for smoking, the excess risk was 0.85 per 100 WLM (95% CI: 0.12-2.79%), which is still statistically significant. The relative risk related to smoking was equal to 3.04 (95% CI: 1.20-7.70). This analysis shows a relative risk of lung cancer related to smoking similar to that estimated from previous miners' cohorts. After adjustment for smoking, the effect of radon exposure on lung cancer risk persists, and its estimated risk coefficient is close to that found in the French cohort without smoking information.

RÉSUMÉABSTRACT Polonium 210, an important naturai reference for radiological protection. Natural polonium 210 which has a relatively short decay period (138 days) and is uranium decay serie daughter should retain more radiological attention because it induces chronic doses higher than that of traces of caesium 137 and plutonium isotopes (238,239,240) in the environment. In the earth's cmst, uranium is present together with radium, radon and its daughter products, at a concentration of about 40,000 Bq t-'. As a consequence of radon 222 exhalation from soils within a metric layer and of lead 210 (radon daughter) falldown, there is an enrichmeut of polonium 210 radioactivity in top layer soi1 relatively to radium concentration, within a factor varying from 2.7 to 8.8 according to environmenial measurements. Human exposure to polonium 210 by ingestion is not negligible. The induced exposure by ingestion of natural polonium 210 is 30 to 70 times higher than that of caesjum from Chernobyl falldown at Helsinki in 1986. Moreover, the latter decreases in relation with the 30 years' decay period while that from radon daughters remains. Comparison with plutonium shows a 500 to 2, OOO times stronger health effect by ingestion for the same number of deposited becquerels on soil. "Hot spots" may occur in the environment: polonium 210 is particularly concentrated by marine fauna, as shown by several measurement programs over the area of north-east Atlantic.'
