据联合国原子辐射效应科学委员会(UNSCEAR)1988年的最新估计,氡(Rn)及其短寿命子体对广大居民产生的年有效剂量当量为1.1msv,约为天然本底辐射人均年有效剂量当量2.4msv的一半。氡是造成呼吸系统疾患和肺癌的主要病因。国际学
According to the latest UNSCEAR estimate in 1988, the annual effective dose equivalent of radon (Rn) and its short-lived progeny to the general population is 1.1msv, which is about the annual per capita effective dose equivalent of natural background radiation Half of 2.4msv. Radon is the main cause of respiratory disorders and lung cancer. International Studies
