Comparison of the Performance of Commonly Used Personal Radiation Dosimeters Under γ-ray

With the Fukushima nuclear power plant nuclear water pollution incident occurred, people are particularly concerned about the impact of radiation on the environment and health.Personal radiation dosimeter can directly reflect the dose rate in the environment, in the daily work and life of prominent role, so its performance is an important issue worthy of attention.In this paper, the personal radiation dosimeters which are commonly used in the market at present are tested by means of the standard equipment of air kerma rate by γ-rays, the monitoring data about dependence of response and relative intrinsic error are analyzed and compared that semiconductor dosimeter is superior to the GM tube dosimeter, on the whole, the comprehensive performance of imported instruments is better than that of domestic instruments.
