本文报道了湖南省19个非铀矿山中的氡子体α潜能浓度和防护现状,α潜能平均浓度在1.31～1107μJm~(-3),其中13个矿山超过了ICRP推荐的工作人员摄入限值。对7个矿山的井下工作人员肺癌发病情况作了记录,大多数矿山防护不良,对今后的防护工作提出了建议。
In this paper, the potential concentration of radon progeny α in 19 non-uranium mines in Hunan Province and their protection status are reported. The average potential α potential is between 1.31 and 1107 μJm -3, of which 13 mines exceed the ICRP recommended staff intake limit value. The records of lung cancer incidence of underground workers in 7 mines were recorded. Most mines were in poor protection and put forward suggestions for future protection work.
