新疆某流域某断面水体放射性水平调查

Investigation on radioactivity level of water in a section of a river basin in Xinjiang

目的:调查新疆某流域总α、总β放射性水平在近五年的变化,掌握新疆某流域总α,总β放射性水平状态,为开展环境辐射水平提供依据。方法:连续五年采集新疆某流域某断面样品,频次为每半年一次。经过滤蒸发浓缩等处理,使用MPC9604型低本底α、β计数器进行测量,得到新疆某流域放射性水平状况,与近五年内数据进行比较。通过对新疆某流域某断面总α、总β放射性水平的调查,为应急情况下快速监测评估放射性污染等工作提供科学数据。

To investigate the changes of total alpha and total beta radioactivity levels in a basin in Xinjiang in the past five years,and to master the state of total alpha and total beta radioactivity in a basin in Xinjiang,providing a basis for environmental radiation levels.The method is to collect samples of a section of a river basin in Xinjiang for five consecutive years,once every six months.After being treated by filtration,evaporation and concentration,the MPC9604 low backgroundαandβcounters were used to measure the radioactivity level of a basin in Xinjiang,and compared with the data in the past five years.Through the investigation of the total alpha and total beta radioactivity levels of a section of a river basin in Xinjiang,scientific data is provided for the rapid monitoring and evaluation of radioactive pollution in emergency situations.
