ICRP新剂量限值对氡子体职业性照射年照射量限值影响的探讨

Study of influence of ICRP NEW dose limit on annual limit on exposure for occupational exposure to radon progeny

从公众剂量限值和环境保护的角度考虑，这一做法值得研究。

Owing to the consideration of public dose limit and environment protection , this method needs discussion .

结果：新标准在职业照射剂量限值、辐射防护管理、放射性废物管理、健康管理以及管理职责等方面作了较大的修改和补充。

Results : Considerable modifications and additions were made concerning occupational radiological exposure limits , radiation protection management , radioactive waste control , health management , leadership responsibilities etc.

依据工作人员职业照射剂量限值的变化，结合我国实际情况，对铀矿井下空气中氡及氡子体浓度管理限值的确定及其参数选择进行了探讨。

According to the change of occupational exposure dose limit for workers , as well as actual circumstances in China , radon and daughter concentration limit in the underground uranium mine and the parameter to be chosen were discussed in this paper .

部分碳化砖房居民的年附加有效剂量超过公众限值标准（1mSv），部分矿工的年附加有效剂量超过职业性照射年剂量限值（20mSv）；

The additional annual effective doses to a fraction of inhabitants are in excess of the public limits of 1 mSv , and those to the part of miners exceed the annual dose limit , 20 mSv , of occupational exposure .

辐射环境质量评价表明80km范围内最大个人有效剂量是公众剂量限值的十万分之四，健康危害是危害约束值的千万分之二。

Quality assessments of radiological environment shows that maximum individual effective does is 4 / 105 of does limit , detriment is 2 / 107 of detriment constraint within 80 km .

对于医学诊断中病人接受的剂量，个人剂量限值不适用，但放射防护最优化却可以发挥大的作用。

For the exposure of patients in diagnostic radiology , individual dose limit does not apply , but optimization of radiological protection may play a major role .

后二种型号料位计对维修人员年最大接受剂量当量，只有国家剂量限值的1／2～1／3。

The biggest dose equivalent that maintenance workers accepted per year is only equal to 1 / 2 ~ 1 / 3 of the dose limit value which state stipulated .

对于小型核设施及核技术应用项目，当简单模型或基本模型的个人年有效剂量的计算结果低于年剂量限值时，简单模型或基本模型适用于该项目的辐射环评。

For minitype nuclear facilities or nuclear technique application item , when individual annual efficient dose calculation result of simple model or basic model is less than annual dose restrict value , simple model or basic model is fit to its radiation environmental assessment .

目的研究脉冲噪声作业工人语言听力损伤与噪声接触剂量之间关系，探索保护作业工人健康的噪声接触剂量限值。

Objective To study on the relationship between hearing impairment caused by pulse noise and the noise exposure level , and to explore the exposure limit to protect the worker 's health .

在1600名职业人员中，有0.18%的人员年剂量超过国家基本标准（50mSv）。96%的人员年剂量低于年剂量限值的1/10。

Conclusion Average outside radiation dose of 0.18 % personnel exceeded the national basic standard ( 50mSv ), the dose of 96 % personnel was lower than 1 / 10 of the year limit dose in the year .

待积有效剂量当量为0.19μSv·a~（-1），仅为ICRP1977年规定的公众年剂量限值的五千分之一和UNSCEAR1982年估算的正常本底地区天然辐射所致剂量的万分之一。

Because of taking environmental tritium in the area , the annual committed effective dose equivalent was 0.19 μ Sv which is only one five thousandth of annual limited dose to the public proposed by ICRP and one ten thousandth of the natural background estimated by UNSCEAR in 1982 .
