【摘要】 本文报道了中国原子能科学研究院 1993～ 1998年同位素研制与生产人员的个人剂量监测结果。外照射个人监测结果表明 ,1993～ 1998年 ,受监测人数共计 2 35 3人 ,受监测人员的集体有效剂量为7.0 3人· Sv,年人均有效剂量为 2 .99m Sv,年有效剂量超过 15 m Sv的人数为 94人 ,占总监测人数的4 .0 % ,其中有 7人超过了 5 0 m Sv,占总监测人数 0 .3%。各年度集体有效剂量在 0 .78～ 1.6 4人· Sv之间 ,年人均有效剂量在 1.91～ 4 .19m Sv之间 ,从 1993到 1996年 ,年人均有效剂量逐年下降 ,从 3.4 2 m Sv下降到 1.91m Sv,从 1997年开始又有所上升 ,1998年上升到 4 .19m Sv。在内照射个人剂量监测方面 ,1993～ 1998年 ,共监测了 10 4 8人次 ,发现内污染者 6 6 8人次 ,占总监测人次的 6 3.7%。内照射剂量估算结果表明 ,1993～ 1998年间 ,受监测人员的年人均待积有效剂量为 8.9× 10 -2 m Sv,总监测人数为 86 4人 ,集体待积有效剂量为 7.7× 10 -2 人· Sv。各年度工作人员所受年人均待积有效剂量在 1.8× 10 -2 ～ 2 .2×10 -1m Sv范围内 ,年集体待积有效剂量在 2 .9× 10 -3 ～ 2 .4× 10 -2 人·Sv范围内更多还原

【Abstract】 The results of individual dose monitoring for workers of the development and production of radioisotopes in CIAE(1993～1998) are presented. The results of external individual dose monitoring show that annual average effective dose was 2 99 mSv for the 2 353 persons from 1993 to 1998,the collective effective dose was 7 03 man·Sv The number of individuals who received an effective dose greater than 15 mSv was 94 persons, accounting for about 4 0% of the total monitored workers There are 7 individuals who received a dose greater than the dose limit(50 mSv), accounting for 0.3% of the total 1 048 person times have been monitored for internal exposure, among them, 668 person times presented a significant internal contamination, accounting for about 63 7% of the monitored workers The annual average committed effective dose was 8 9×10 -2 mSv for the 864 persons from 1993 to 1998,the collective committed effective dose was 7 7×10 -2 man·Sv The annual average committed effective dose was within the range of 1 8×10 -2 ～2 2×10 -1 mSv and the collective committed effective dose was within the range of 2 9×10 -3 ～2 4×10 -2 man·Sv in 1993~1998 (更多还原
