Objective To conduct a multi factorial analysis on total death and malignant tumor death among the staff in one nuclear industry institute. Methods FoxPro software was used to establish the database; SPSS software was used to carry out the unconditional logistic regression analysis on causes of total death and malignant tumor death. Results It showed that the accumulated radiation dose by the end of 1980 was not selected into the regression equation. The associations of attained age and smoking with both total death and malignant tumor death were all positive ( P 0.05) ; the association of sex( P 0.05) with both total death and malignant tumor death were all negative ( P 0.05) and radiological working duration ( P 0.05) with total death were negative. Conclusion This paper suggest that no harm effects of low dose external irradiation were observed in this multi factorial analysis; however, more attention should be paid on the risk of total death and malignant tumor death induced by smoking in this nuclear industry institute.
