Research of Natural Radioactivity Level and Environmental Impact:Assessment in The River Region

摘要：

　　The main purpose of the article is to investigate the ecological environment problem of radioactive pollution in a river area of mid-southern Sichuan.The absorbed dose rate from gamma radiation and the contents of radionuclide in the environmental samples were investigated and measured.Gamma energy spectrum was measured,covering the survey area of 860 km2 with the grid of 0.5× 0.5 km2 (a total of 3567 measuring points).The distribution map of gamma radiation absorbed dose rate in the region of river was described.
