贵州省放射工作人员外周血淋巴细胞微核分析

目的 了解我省放射工作人员健康状况，为保障贵州省放射工作人员的健康提供科学依据。方法 对长期接触慢性小剂量电离辐射的放射工作人员及半年内未接受照射的大学生，采用外周血淋巴细胞常规培养法培养、制片、检测、统计分析。结果 放射工作人员微核率检出率明显高于对照组，差异有统计学意义（P<0.01）；不同放射工种、不同放射工龄的放射工作人员外周血淋巴细胞的微核率有差异，且差异有统计学意义（P<0.01），不同性别放射工作人员外周血淋巴细胞微核率差异无统计学意义（P>0.01）。结论 长期小剂量电离辐射对放射组工作人员的健康具有一定的影响，应培训防护知识，加强放射防护工作。

Analysis of micronucleus rate in peripheral blood lymphocytes of radiation workers in Guizhou Province

Objective To understand the health status of radiation workers in Guizhou Province and provide a scientific basis for ensuring the health of radiation workers in Guizhou Province. Methods For radiation workers exposed to chronic low-dose ionizing radiation for a long time and college students not exposed to radiation for half a year, peripheral blood lymphocyte were cultured, prepared, detected and statistically analyzed. Results The detection rate of micronucleus in radiation workers was significantly higher than that of the control group, with statistically significant (P<0.01). The micronucleus rate of peripheral blood lymphocytes of workers with different types of radiation work or different radiation ages had significant difference (P<0.01). There was no statistically significant difference between workers with different genders (P>0.01). Conclusion Long-term low-dose ionizing radiation has a certain impact on the health of radiation workers. It is necessary to train protection knowledge and enhance radiation protection.
