Monitoring of environmental gamma radiation dose rate in Zhejiang province

This paper introduces the monitoring results of environmental gamma radiation air absorbed dose rate by Zhejiang Province Radiation Environmental Monitoring Center during Japan nuclear leakage accident. Monitoring includes continuous and instantaneous surveillance measurements in Hangzhou and Zhoushan areas and around Qinshan nuclear power base. The results indicated that Japan nuclear leakage accident caused by the earthquake did not significantly influence the environmental gamma radiation air absorbed dose rate level in Zhejiang Province.
