摘　　要：以镭污染的低、高比活度的土壤样品为例,通过样品的226Ra比活度与贯穿辐射剂量率的相关性试验,得到样品贯穿辐射剂量率与其226Ra比活度之间关系的经验公式,从而快速模拟计算出镭污染土壤的比活度,满足退役治理工程的需要。Taking radium contaminated soils with low and high speeific activity for example,a rapid calculation method for radium specific activity in the contaminated soils is presented.According to experiments on the correlation between radium specific activity in the soil samples and exposure dose rate,two empirical equations are obtained.The calculation method was validated in the disposal engineering of radium contaminated soil.The radium specific activity in the soil samples can be rapidly calculated by the empirical equations.
