本文报道了山西省1987年~1992年用热释光方法监测的职业外照射个人剂量水平。尤其对1990年3124名职业人员的受照剂量作了分析,结果年剂量最高为111.5mSv,均值为1.79mSv。按职业分类:医用诊断X射线、核医学、放射治疗、工业探伤、地质物探、教学科研及其它人员的平均年剂量依次为1.95mSv,1.17mSv,0.92mSv,2.13mSv,1.73mSv,0.64mSv和1.15mSv。在3124名职业人员中,有0.3%人员的年剂量超过了国家基本限值(50mSv);但95%人员的年剂量没超过该限值的3/10;89.8%人员的年剂量没超过该限值的1/10;文中还对较大剂量的原因进行了分析,并与不同地区的监测结果作了比较
This paper reports the personal exposure dose levels monitored by thermoluminescence in Shanxi province from 1987 to 1992. In particular, the exposure of 3124 occupational workers in 1990 was analyzed. The highest annual dose was 111.5 mSv, with a mean of 1.79 mSv. According to occupational classification: Medical diagnosis X-ray, nuclear medicine, radiotherapy, industrial flaw detection, geophysical exploration, teaching and research and other personnel average annual dose of 1.95mSv, 1.17mSv, 0.92mSv, 2.13mSv, 73mSv, 0.64mSv and 1.15mSv. The annual dose of 0.3% of the 3124 occupational personnel exceeded the national basic limit (50mSv); however, the annual dose of 95% did not exceed 3% of this limit; the year of 89.8% of the staff The dose did not exceed 1/10 of the limit; the reason for the larger dose was also analyzed and compared with the monitoring results in different regions
