Abstract
Personal radiation dosimeters are used to monitor the dose of radiation that an individual has been exposed to.Personnel engaged in radiation-related work can estimate and determine the magnitude of dose rate in the radiation environment they are in by reading the personal dose equivalent rate on the personal radiation dosimeter.Therefore,the value of the personal dose equivalent rate is particularly important.The personal radiation dosimeters are often stuck to the clothes on the chest or placed in pockets,which are often positioned at multiple angles to the direction of radiation.In this paper,based on the air kerma standard equipment of X-ray and γ-ray protection in Shandong Institute of Metrology,the RG1100 model of personal radiation dosimeters is calibrated at multiple angles.It is found that the personal dose equivalent rate of this model of personal radiation dosimeter varies greatly when it is at 0°,90° and 180° to the direction of radiation,and the deviation is the largest when it is at 90°.The calibration factor of the personal radiation dosimeters relative to the standard value is the largest when it is at 90° to the direction of radiation.The results show that when engaged in X-ray related work,radiation workers should pay attention to wearing personal radiation dosimeters correctly in order to avoid the hazards of excessive radiation.关键词
