摘　　要：为了评估稀土尾渣的辐射水平,本文以典型的独居石选冶生产稀土后产生的含钍尾渣作为研究对象,应用蒙特卡罗模拟方法来计算桶装含钍尾渣周围的空气吸收剂量率。模拟计算结果与实测结果比较相对偏差均未超过20%,表明用蒙特卡罗模拟方法来预测稀土尾渣辐射水平是可行的。In order to evaluate the radiation level of rare earth tailings,this paper takes thorium-containing tailings after rare earth production from typical monazite beneficiation as research object,and uses Monte Carlo simulation method to calculate the air dose rate around the thorium tailings bucket.The relative standard deviations between the simulated calculation results and the measured data did not exceed 20%,indicating that it is feasible to apply Monte Carlo simulation method to predict the radiation level of rare earth tailings.
