摘要
通过实际勘测现场与建模模拟相结合检测方法,给出某基地放射源库辐射场分布,并对源库内指定的辐射观测点进行实际探测和模拟计算γ辐射剂量,将γ辐射剂量的实测值和模拟值进行误差比较,发现误差范围在可允许误差10%范围内,为进出源库人员提供合理化的防护建议。
By using the detection method of combining the actual survey site and modeling simulation,the radiation field distribution of a base radiation source library is given,and the actual detection and simulation calculation of radiation dose are carried out for the designated radiation observation points in the source library,comparing the error between the measured value and the simulated value of radiation dose,it is found that the error range is within 10%of the allowable error,which provides reasonable protection suggestions for the personnel entering and leaving the source library.
