氡及其子体的辐射问题,在铀矿或非铀矿都普遍存在。然而在我国,对非铀矿山氡子体的辐射防护并未象铀矿山一样得到应有的重视。这主要是因为人们一般认为非铀矿的氡子体辐射问题并不十分严重,而且氡子体诱发肺癌的潜伏期长达15～40年。我国多数非铀矿山是在解放后逐步建立起来的
Radon and its daughters radiation problems, uranium or uranium are ubiquitous. However, in our country, the radiation protection of radon progeny in non-uranium mines has not received the same attention as uranium mines. This is mainly because people generally think that non-uranium radon progeny radiation problems are not very serious, and radon progeny induced lung cancer incubation period of up to 15 to 40 years. Most non-uranium mines in our country are gradually established after the liberation
