Taiyuan City, Part Of The Radiation Staff Health Survey

Objective:The aim of this study was (1) to investigate the physical condition of radiation workers in Taiyuan who works under low doses by analyzing dynamic changing of health indicators from 2002-2009 and the health effects of radiation in 2009; (2) to find a scientific way to strengthen the health management for radiation workers; and (3) to provide some suggestions and basis for establishing appropriate protective measures.Methods:2002-2009 radiation workers healthy records and personal files were recorded in Taiyuan CDC. By retrospective epidemiological survey, documents of 1350 radiation workers who worked in diagnostic radiology, nuclear medicine, industry detection and radioisotope applications were collected including social demographic, health and occupation related factors, some physical test for general medicine, skin, eye lenses, routine blood, chromosome aberration and assistant examination. The collected data were established, sorted, described and analyzed by SPSS 13.0.Results:(1) During 2002-2009, all health effect indicators showed no significant regular change. (2) Univariate analysis for the 2009 radiation workers including social demographic, health related and job related factors showed that there were significant differences among different factors in the detection rate of neurasthenic syndrome, skin check, blood pressure, crystal, blood routine, cell cytogenetic, B-anomaly. (3) Multivariate logistic regression showed that neurasthenic syndrome was related to smoking, personal medical history and BMI. Older age was a risk factor for abnormal skin. Abnormal blood pressure was related to older age, higher job title, personal abnormal blood pressure history, and abnormal BMI.γ-ray radiation workers had higher risk for abnormal blood pressure thanχ-ray radiation workers. Lens opacity was related to long length of service. B-anomaly detection rate was related to male, older age, and abnormal BMI.Conclusion:(1) At present, radiation on health status of radiation workers is safe, and low-dose radiation has little effect. In other words, the radiation workers are in good health and have no rays related injuries when most person-doses are less than one-tenth of the national standards.(2) Some chronic diseases, such as hypertension and fatty liver which often caused by modern life styles, also occur in radiation workers.(3) Researchers general interested routine peripheral blood and lymphocyte chromosome aberration are not associated with occupational factors.
