Título Skeletal 210Pb levels and lung cancer among radon-exposed tin miners in Southern China
Información bibliográfica Mar. 1993, Vol.64, No.3, p.253-259. 23 ref.
Resumen A preliminary case-control study of 19 lung cancer cases over 55 years of age and 141 age-matched controls was carried out among underground tin miners exposed to 222Rn and its decay products. Radon exposure was estimated through measurement of 210Pb activity levels in the skull, and in working level months. There was a smooth gradient of lung cancer risk with categories of skeletal 210Pb level at time of last radon exposure; relative risks of 1.0, 2.9, 3.2, and 4.7 for categories <51.8, 51.8-77.7, 77.8-107.3, and >107.3Bq (<1,400, 1,400-2,099, 2,100-2,899, and >2,899pCi), respectively. Relative risks were unaffected by adjustment for exposure to arsenic in the mine or by adjustment for working level months. Risks also increased with cumulative working level month exposure, but the gradient of risk lessened after adjustment for exposure to arsenic. 210Pb, at the time of last radon exposure (p=0.13) and at the current 210Pb level (p=0.01), was not highly correlated with the working level month estimate.
