| 摘 要： | 给出了一种考虑子体影响的放射性剂量评价方法,并用此法对铀尾矿中234U通过地下水迁移对人体所致剂量进行了估算.结果表明,子体230Th对整个剂量的贡献值远远大于母体234U.因此,在剂量评价中,需要考虑子体的影响,尤其是计算结果和剂量限值比较接近时,考虑子体的影响尤为必要,只有这样才能保证安全需要.

| Abstract: | A dose assessment method considering the effect of progenies is presented in this paper,and the dose from 234^U is evaluated using this method. Results show that the dose from 230^Th is much larger than its parent 234^ U. Therefore,progenies must be taken into account, especially when the dose is close to the limit. Only in this way can safety demand be met. |
