Abstract: To elucidate the effects of low-dose radiation exposure and lifestyle on physical health and mental health, we evaluated the relationship of age, cumulative radiation dose, and lifestyle (cigarette smoking, alcohol drinking and physical exercise) to physical and mental health in Japanese radiological technologists. The study subjects were 932 Japanese radiological technologists who participated in a health study from 1981 to 1985. A self-administered questionnaire was mailed to each subject to obtain information on the items listed above. Items that measured the status of physical and mental health were summarized as several indices and several categories based on the principal component analysis and quantification method III, respectively. The association of age, cumulative radiation dose and respective categories of lifestyle with summarized indices for physical health and summarized categories for mental health were analyzed using multivariate linear regression and multiple linear logistic regression, respectively. A significant decrease with age was observed in physical health but not in mental health except for stress and physical complaints. No significant effects of cumulative radiation dose were observed on physical or mental health. Unfavorable effects of current-smoking were observed in some categories of physical health and mental health. In contrast to cigarette smoking, current alcohol drinking, especially lightdrinking, showed favorable effects in several categories of physical health and mental health, while ex-drinking showed unfavorable effects in some categories of mental health. Favorable effects of physical exercise, especially of high-intensity exercise were observed on both physical and mental health. Effects of occupational exposure to radiation may be negligible in Japanese radiological technolo- gists and improvement of lifestyle is the essential factor for enhancing physical and mental health conditions.
