【摘要】：目的了解長(zhǎng)期低劑量職業(yè)照射對(duì)放射工作人員健康影響。方法采用流行病學(xué)橫斷面調(diào)查方法,調(diào)查分析2013年山東省臨沂市6所三級(jí)醫(yī)院的624名放射工作者健康狀況。結(jié)果放射工作人員人均年劑量5m Sv者占97.28%;淋巴細(xì)胞微核率為57.85%(361/624),染色體畸變率為53.21%(332/624);血常規(guī)指標(biāo)受暴露年限、年均劑量及累計(jì)劑量的影響,差異均有統(tǒng)計(jì)學(xué)意義(均P0.05);甲狀腺激素水平、染色體畸變率、淋巴細(xì)胞微核率及眼晶狀體渾濁率與暴露年限及累計(jì)劑量有關(guān),差異均有統(tǒng)計(jì)學(xué)意義(均P0.05)。結(jié)論長(zhǎng)期低劑量職業(yè)輻射可使機(jī)體產(chǎn)生一定的輻射損傷,應(yīng)加強(qiáng)放射工作人員防護(hù)。
[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.
