To explore the impact effects of γ radiation dose rate measurement results using different measurement methods,analyse the differences between different methods,and explore the reasons.There are four monitoring methods of measuring γ radiation dose rate:real-time measurement using a radiation dose rate meter,automatic continuous measurement using a radiation environment monitoring station,cumulative dose measurement using a thermoluminescence dosimetry measurement system,and indirect calculation of radioactive nuclides in soil γ Radiation dose rate.This article explores the use of portable devices and compare and analyze the measurement results.The results show that when all methods without deduct the cosmic ray response,the automatic continuous measurement value>cumulative dose monitoring value>immediate measurement value>indirect calculation value(excluding cosmic ray contribution).After deducting the cosmic ray response,the indirect calculation value(excluding cosmic ray contribution)>immediate measurement value.This experiment to some extent indicates comparability of using different measurement methods and equipment for conducting γ radiation dose rate,providing reference for optimizing radiation environment measurement methods.
