External ambient radiation exposure and cancer mortality trends around Qinshan nuclear power plant phase I: long-term study before and after service extension

This study evaluates the ambient external radiation levels and their association with public health around the Qinshan Nuclear Power Plant (QNPP) before and after the extended service of its Phase I project. By monitoring the cumulative ambient external exposure around QNPP from 2010 to 2023 and analyzing the health data of residents in Haiyan County from 2012 to 2022, changes in cancer mortality-related rates were examined. Results showed that during the study period, ambient radiation around Q
