异常环境因素对热释光剂量计的影响

Abstract

Abstract: In order to ensure the accuracy of personal dose measurement, study on the change of relative response of TLD2000C LiF(Mg,Cu,P) thermoluminescence dosimeter (TLD) under the influence of abnormal environmental factors was conducted. Performance experiment in the conditions of normal and abnormal environmental factors, such as high temperature and high humidity, water immersion and high electromagnetic radiation, and the difference of relative responses of TLD between different environmental factors were analyzed. The change of relative response of TLD is about -7% under high temperature and high humidity conditions, and The effect of short time immersion and high electromagnetic radiation environment on the relative response of TLD is very little. High temperature and high humidity environment will produce minus change to the relative response of TLD, therefore attention should be paid in the process of use, storage and transportation. Short time immersion or rain fall has little effect on the relative response of TLD. The experimental results have good reference value. TLD can be read and used normally when placed in high electromagnetic radiation environment.

Key words: thermoluminescence dosimeter (TLD), abnormal environmental factors, change of relative response
