Lung cancer risk from radon modifiers of exposure-effect relationship

Studies of underground miners of uranium and other substances are at present the principal source of information on the long term effects of exposure to radon and its progeny. One of the largest such studies is that of uranium miners in West Bohemia (Jachymov). This study, sometimes referred to as the S cohort, was set up in 1970 by the late Josef Sevc. The purpose of this paper is to show, how the exposure - effect relationship is modified by time since exposure, age at exposure, and exposure rate. (author)
