北山预选场区未来人类活动辐射环境评估

Radiation Environmental Assessment of Future Human Activities in Beishan Pre-selected Sites

通过分析计算高放废物地质处置库关闭后,人类未来活动深井取水情景下,附近居民的受照剂量,得出在处置库系统保持稳定及屏蔽作用有效时,居民在围岩外深井取水,接受到的处置库泄漏核素所致剂量的最大值之和为0.522μSv/a,辐射环境影响可接受。

After analyzing the exposure dose of the nearby residents under the deep well water in-take scenario in the high-level radioactive waste geological repository.It is concluded that when the repository system is stable and the shielding effect is effective,the residents take water from the deep well outside the surrounding rock,and the sum of the maximum doses of the received nuclides from the disposal warehouse is 0.522μSv/a,and the radiation environmental impact is acceptable.
