Determination of Uranium Contents in Tap Water of Lanzhou City and in Mineral Water of the Wuquan Mountain Using Fission Track Method
用裂变径迹法测量兰州自来水中铀的含量

This paper describes how the fission track method was used for determinating uranium in tap water and mineral water sampled from Lanzhou and the Wuquan Mountain respectively. The natural uranium concentration were calculated in absolute and relative measurements. The quantitative difference of both results obtained was 3.6%. The concentration range of uranium calculated with the absolute measurement was 4.4-7.4×10-6 g/L, and the total experimental error was within 10%. The uranium concentration in mineral water is higher. Compared with uranium concentration in tap water of Beijing,(continued on inside back cover)(cantinued from page 96)the lowest value in Lanzhou was high twice as much,but its highest value was similar to that in Beijing.
