Environmental radiation monitoring at Qinshan nuclear power base (1992-2011)

This paper introduces the environmental radiation monitoring at Qinshan Nuclear Power Base from 1992 through 2011, including the design of monitoring program, monitoring equipment and methods, quality control measures, and the monitoring data of some major radionuclides as well. Then by analysis, technical challenges and lessons drawn through practices are summarized. Results show the running of Qinshan Nuclear Power Base has no perceptible effects on the environment, and its radioactive environmental quality remains basically at the same level as the background investigated before operation.
