Abstract: In December 2013, an intercomparison of environmental gamma radiation dose rate and cosmic ray response measurements within the national radiation environmental monitoring network was held in Liangshan Yi Autonomous Prefecture, Sichuan Province, which was organized by RadiationMonitoring Technical Center of Ministry of Environment Protection. A total of 47 sets of instruments from 32 member units participated in the intercomparison measurements at 7 environmental measuring points. All the results are unified interms of absorbed dose rate in air. Results of different types of instruments are independently evaluated by Z score values. It is found that the data of scintillation counters have relatively wider dispersion than those of high pressure ionization chambers. Besides the cosmic ray response points, the results of both keep good linearity.
