摘　　要：随着科技的发展,加速器质谱技术(AMS)越来越多的应用于辐射环境监测领域,AMS的测量结果通常以同位素原子数之比的方式为单位,而在辐射环境监测领域,多以放射性活度(Bq)形式给出最终结果,它们之间结果的换算就显得尤为重要。从不同方法测量结果的定义出发,尤其是14C断代领域常见的单位pMC,推算AMS测量结果与放射性活度的换算公式。该方法能用于辐射环境监测领域的数据参考,同时对环境监测方法的评估有一定价值。With the development of technology,AMS is used more and more radiation environment monitoring field.The unit of AMS measurement results is often isotope atom radio,but Bq is the often used units radiation environment monitoring,so the unit conversion of the two methods are more important.Based on the definition of results from different methods,especially the pMC which is often used in radiocarbon dating,the formula for AMS measurement results to radioactivity was derived,which can be used for data reference in environment monitoring
