Environmental radiation monitoring around the nuclear facilities

The environmental radiation survey and monitoring were carried out at the KAERI site and Kori nuclear power plant site to establish the radiological conditions of each site, and to record permanently the results for the future comparisons. For the KAERI site various environmental samples were collected three times a month and, the natural background radiation levels were also measured at each sampling point. For the Kori site, several environmental samples such as surface soil, pine needles, and water samples were quarterly collected at 19 points of on, off-site and, at the same time, the natural background radiation levels of each sampling point were measured. The measurement for gross α and β radioactivities of the environmental samples thus collected and treated were measured for all samples. The results obtained were statistically evaluated and summarized in numerical tables. (author)
