[The "dose-response" mechanism of tumorigenesis in workers of radiochemical plants].
The "dose-response" mechanism has been studied for three main histological types of tumor in a cohort of 500 workers occupationally exposed to different doses of radiation (162 patients with lung cancer and 338 practically healthy persons) using the "case-control" method and multifactorial logic regression procedure. A non-linear threshold dependence was established for incorporated plutonium, with the threshold being at 8 kBq to correspond to 80 kGy. This relationship has been particularly distinct in cases of adenocarcinoma. No significant results have been obtained for the "dose-response" relationship in chronic external exposure to gamma irradiation. Said dependence for tobacco smoking appeared to be linear. Most pronounced variations were recorded for squamous cell carcinoma.
