| 本文调研了医用诊断X线及其90度方向距离中心束1米处散射线线质。根据调研结果及硫酸钙、氟化锂热释光元件的特性,提出了用不加补偿的硫酸钙元件作为医用诊断X线工作者个人剂量计的能量校正法。同时。本文通过模拟实验确定能量校正系数为0.13。这种方法已用于北京市个人剂量服务。 |

| This paper describes an investigation on the quality of the primary beam of diagnostic X-rays and the scattered X-rays at 90°and at a distance of 1m from the centml ray of the primary beam.According to the result of this investigation and the characteristics of calcium sulphate and lithium fluoride thermolumineseence dosimeter.An energy response modification method for using uncompensated calcium sulphate as a perseal monitor for medical diagnostic X-ray workers was proposed.An energy fesponse modification factor,which is about 0.13.Was determined by a simulating experiment.This method has been used in personal dose monitoring sevice in Beijing.The data showed the feasibility of this method. |
