【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５３７－１和５３７－２。年内分别在库周围取地下水（或土）６次，对５３７－１得到地下水和泥土中的铀含量大约为１．２７μｇ／Ｌ和３．０μｇ／Ｌ，对５３７－２得到的地下水中的９０Ｓｒ含量约为５．３５×１０－３Ｂｑ／Ｌ。上列数据与本底无明显差异。可见，５３７－１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，５３７－２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 for mer location of Institute of Nuclear Physics and Chemistry,China Academy of Engi neering Physics.The groundwater (or the soil)samples around the vaults were taken 6 times in one yea r separately.Contents of uranium in the groundwater and the soil around Vault 53 7－1 are about 1.27μg/L and 3．01μg/L respectively and the content of strontiu m －90 in the groundwater around Vault 537－2 is 5．35×10-3 Bq/L or so.Ther e i s not obvious difference between the above data and radioactive background level there.It is thus evidents that there is no obvious difference of uranium conten t between groundwater and river water in the residential area ne ar Vanlt 537－1 and there is no obvious difference of strontium－90 contents bet ween the area of Va ult 537－2 and the residential area.So far the obvious influence of radionuclide s in the two waste vaults on groundwater around the vaults has not been found.更多还原
