摘　　要：为掌握抛投式自动站在东北沿朝边境地区的本底监测数据,通过在吉林省白山市和延边州布放抛投式自动站,获取了长白山周边地区的γ吸收剂量率监测数据。经过对监测数据的分析与评价,目前,白山市和延边州的抛投式自动站监测数据在本底范围内,未见异常值。部分地区γ空气吸收剂量率偏高,可能由于基建、采矿等人类活动造成。监测结果可为在后续应对周边国家核活动中抛投式自动站的应用提供应急决策研判的数据基础。In order to grasp the background monitoring data of the casting automatic stations in the northeast border areas,the monitoring data of the absorbed dose rate around Changbai Mountain were obtained by deploying the casting automatic stations in Baishan city and Yanbian prefecture of Jilin Province.Through the analysis and evaluation of monitoring data,at present,the monitoring data of the castting automatic stations in Baishan city and Yanbian Prefecture is within the background range,and there is no abnormal value.In some areas,the air absorbed dose rate of γ is high,which may be caused by human activities such as infrastructure and mining.The monitoring results can provide the data basis for emergency decision making and judgment in the follow-up response to the nuclear activities of neighboring countries.
