浙江省地下轨道交通氡浓度水平调查及污染防治

摘要

The radon level in air of Ningbo metro Line 1 and Hangzhou metro Line 1 have been invested. On the basis of the radon activity monitored, the annual average effective exposure dose of workers and the public is given according to the evaluation approach recommended by the United Nations Scientific Committee on the Effects of Atomic Radiation ( UNSCEAR) . Suggestions on protection and reduction of radon level in metro are presented.%为了解浙江省地下轨道交通氡浓度水平现状，对现据有轨道交通的杭州、宁波两个城市中的轨道交通氡浓度进行了监测，估算了车站内氡及其子体所致地铁工作人员及公众人均年有效剂量，并提出了地下轨道交通氡污染防治建议。
