摘要
目的 分析2015—2017年全国放射卫生技术机构生物剂量估算能力考核结果，研判近年来此类机构检测能力发展情况。方法 对2015—2017年参加考核的资料进行分析整理，对合格率、优秀率、参加单位情况及剂量估算偏差分布情况进行统计学分析。结果 合格率逐年升高，2017年同2015年比较，合格率明显提高，差异具有统计学意义（χ2=3.978，P〈0.05）。3年共53家单位参与了生物剂量考核，其中连续3年均参加的单位有30家，占57%。3年连续参加考核单位的剂量估算相对偏差分布情况中，估算偏差在5%-10%内的所占比例升高，15%-20%和〉20%所占比例下降。结论 2015—2017年全国各单位生物剂量估算能力基本保持稳定，检测水平和合格率逐步提升，优秀率保持平稳。
Objective To analyze the biological dose estimation ability of the radiation health technology institutions nationwide from 2015 to 2017, and their development in recent years. Methods SPSS 19.0 software was used to analyze and pack the data involved in the 2015-2017 year assessments by using χ2 test. Statistical analysis was conducted of qualification rate, excellent rate, participating units and dose estimation deviation distribution. Results The qualification rate gradually increased from 2015 to 2017. Compared with 2015, the passing rate significantly increased in 2017 with statistically significant difference（χ2=3.978, P〈0.05）. A total of 53 units participated in the biological dose assessment, of which 30 units were involved over the three consecutive years, accounting for 57%. In the distribution of the relative deviation of dose estimates made by the units participating in the three-year assessment, the proportion of estimated deviations in the range of 5%-10% increased whereas those in the range of 15%-20% and 〉20% decreased. Conclusions During 2015-2017 year period the biological dose estimation ability of all units involved in the assessment nationwide was basically stable, with gradually improved test level, qualification rate and steady excellence rate.
