部分不同工种放射工作人员辐射效应分析

目的 了解电离辐射对不同工种放射工作人员辐射,效应敏感指标的影响,为有针对性的改善放射防护条件提供依据。方法 抽取放射组和对照组人员外周静脉血进行外周血象、染色体畸变和微核细胞检测分析。结果 放射组辐射效应指标异常检出率均高于对照组,染色体畸变异常检出率与之比较,差异有统计学意义(P < 0.05);介入和工业组辐射效应指标异常检出率高于其他组,其中白细胞减少和染色体畸变异常检出率与对照组比较差异有统计学意义(P < 0.05或P < 0.01)。结论 不同工种放射工作人员的辐射效应敏感指标异常检出率均高于正常人群(对照组人员),尤其是介入和工业放射工作人员小剂量辐射损伤效应较明显。建议应有针对性的改善放射防护条件,加强个人防范意识。

Analysis on Radiation Effect of Partial Different Posts of Radiation Workers

Objective To understand the effects of ionizing radiation on the radiation effects of different posts of radiation workers, and to provide basis for improving the radiation protection conditions. Methods Extraction of radiation group and control group staff's peripheral blood hemogram. Detection and analysis were made of chromosome aberration and micronucleus cell. Results Radioactive radiation effect index abnormal detection rates were higher than those of the control group. Chromosome aberration abnormal rate and the difference were statistically significant (P < 0.05); intervention and industrial group radiation effect index abnormal detection rate is higher than that of other groups, which white cells reduce and chromosome aberration abnormal detection rate compared with the control group, the difference has statistical significance (P < 0.05 or P < 0.01). Conclusion A sensitive indicator in the radiation effects of different types of radiation workers abnormal detection rate were higher than the normal population, especially of intervention and industrial radiation workers in small doses of radiation damage effect is obvious. It is suggested that should be aimed at improving radiation protection conditions, strengthen the radiation workers personal awareness.
