摘要
目的通过剂量计比对，提高全国个人剂量监测技术水平。方法全国57家单位参加了比对。每个参比单位提供10组剂量计。盲样比对剂量计在卫生部标准剂量学实验室和中国计量科学研究院接受照射。90％以上均采用热释光剂量计（TLD）。结果实测值与约定真值的相对偏差在10％以内符合，占参比单位的85％左右。结论为了确保工作人员监测质量，定期开展个人监测质量控制比对是非常必要的。
Objective To increase the level of individual monitoring of external exposure by intereomparison in China. Methods Fifty-seven agencies were involved in the intercomparison. Ten sets of dosimeters submitted by each of them were irradiated with conventional doses at NIM or SSDL. Thermoluminescent dosimenters （TLDs） were used by more than 90% of them. Results The relative deviation lied within 10% for 85% of them. Conclusions It is very. necessary to perform such intercomparison periodically for quality control in individual monitoring of external exposure.
