Biao Liu, Yuping Zhou, Deret Ku, et al. The level of 238U and 226Ra in residential drinking water in Xinjiang[J]. Nuclear techniques, 1990, 13(3): 167-171.DOI:
Ra in various supplies of residential drinking water in Xinjiang have been surveyed during 1985—1987.The results show that the average levels for these two nuclidies are proportionally related.The population weighted average values of
238
U and
226
Ra in drinking water are 67.8mBq/1 and 2.98 mBq/1 respectively
and the concentration ranges for
238
U and
226
Ra are 2.1—3770 mBq/1 and 0.15—138mBq/1 respectively. It has been found that the
238
U level in drinking water exceeds the permitted value set by the National Sanitary Standards for 11 sampling sites which account for only 1.7% of the total 668 sites.
