【摘要】 中国工程物理研究院核物理与化学研究所原工作地点 (老点 )存在两个放射性废物库 5 37 1和 5 37 2。年内分别在库周围取地下水 (或土 ) 6次 ,对 5 37 1得到地下水和泥土中的铀含量大约为 1.2 7μg L和 3.0 μg L ,对5 37 2得到的地下水中的90 Sr含量约为 5 .35× 10 - 3 Bq L。上列数据与本底无明显差异。可见 ,5 37 1废物库周围地下水中铀含量与生活区河水中含量无明显差异 ,5 37 2废物库周围地下水中锶含量与生活区河水中含量也无明显差异。至今未监测到两个废物库中的放射性核素对周围地下水中的明显影响更多还原

【Abstract】 There are waste vault 537 1 and vault 537 2 in former address of Institute of Nuclear physics and Chemistry,China Academy of Engineering Physics.The groundwater(or the soil) about the vaults was got 6 time in one year separately.Contents of uranium in the groundwater and the soil about vault 537 1 are 1.27μg/L and 3.01μg/g or so separately and content of strontium 90 in the groundwater about 537 2 is 5.35×10 -3 Bq/L or so.There is not obvious difference between the above and radioactive background.It is thus evident that there is not obvious difference of uranium contents between in the groundwater and in the river water in living area about 537 1 and there is not obvious difference of strontium 90 about vault 537 2.So far the obvious influence of radionuclides in the two waste vaults on the groundwater about the vaults has not been measured.更多还原
