German contribution to the international epidemiological study to the risk of workers in the nuclear industry

The International Agency for Research on Cancer has initiated and coordinated epidemiological cohort studies among employees in nuclear industry in several countries with the aim to carry out a common analysis. The magnitude of the number of persons who are included in this study and the derived number of person-years is assessed in such a range that it should be possible to get information to the risk of carcinogenic effects after a chronic low-dose radiation exposure. The results of that analysis will be compared with the risk factors derived from persons who are exposed by high-dose radiation: e.g. the A-bomb survivors of Hiroshima and Nagasaki. (author)
