長期低劑量職業(yè)照射對放射工作者健康影響
[Abstract]:Objective to investigate the effect of long-term low-dose occupational irradiation on the health of radiation workers. Methods the health status of 624 radiation workers in 6 tertiary hospitals in Linyi City Shandong Province in 2013 was investigated and analyzed by cross-sectional epidemiological survey. Results the average annual dose of 5m Sv in radiation workers was 97.28%, the micronucleus rate of lymphocytes was 57.85% (361 / 624), and the chromosome aberration rate was 53.21% (332 / 624). The blood routine indexes were affected by the years of exposure, the average annual dose and the cumulative dose, the differences were statistically significant (P0.05). The levels of thyroid hormone, chromosome aberration rate, micronucleus rate of lymphocytes and opacity rate of ocular lens were related to the years of exposure and the cumulative dose, the differences were statistically significant (P0.05). Conclusion long-term low-dose occupational radiation can cause certain radiation damage to the body and the protection of radiation workers should be strengthened.
