| 摘 要： | 本文测量了某铀矿不同工种的56名矿工下矿井作业前的呼出气中的~(222)Rn浓度,并由此估算了他们体内的~(226)Ra 负荷量。按不同工种的人数加权,呼出气中的~(222)Rn 浓度平均值为34.1Bqm~(-3),体内~(226)Ra 负荷量的均值为1.95kBq。同时还对9名休息了2天的和2名离开井下作业3—4年的矿工以及12名来下过矿井的本矿工人呼出气中氡浓度进行了测量,由此估算出其体内~(226)Ra 负荷量的均值分别为1.11、0.94和0.17kBq。

| Abstract: | The concentrations of Rn in exhaled breath were measured for 56 miners before they started underground mining in an Uranium mine and after they terminated the mining.On the basis of the measur-ements,the weighted ~(226)Ra body burden of the miners were estimatedto be 1.95 kBq before underground mining.The measurements wereburther carried out for 9 Uranium miners who had 2 days' leaveand for 2 miners who have left underground mining for 3 to 4 years,the average values of ~(226)Ra body burden for these miners were determ-ined to be 1.11 and 0.94 kBq,respectively. |
