*Model adjusted for age at risk, calendar year at risk and duration of employment by stratification. γ-Ray doses were not included in the model.
†p Values from the likelihood ratio test comparing nested model with and without the exposure term.
‡Model adjusted for age at risk, calendar year at risk and duration of employment by stratification. RDP exposures were not included in the model.
CVD, cardiovascular diseases; ERR/Sv, excess relative risk per 1 sievert; ERR/100 WLM, excess relative risk per 100 WLM; n.c., model did not converge; NHL, non-Hodgkin's lymphoma; RDP, radon decay products; WLM, working level months.
