Abstract:: Based on the concentration of U, Th, and K in soil obtained from 1/250 000 geochemical exploration data, this article has made appraisal of Chengdu Economic Region. This paper introduces radionuclide distribution level and radioactive environmental level. By comparing the situation of geology and the natural radioactive environment distribution situation of Chengdu Economic Region, the authors analyze the relation between geological condition and radioactive environment distribution, and preliminarily study the way that radioactive level influenced by geological condition. Finally, the authors summarize the rules of effects caused by geological environment on the natural radioactivity level distribution situation of Chengdu Economic Region. First, the external and internal exposure indexes are both less than the national limit of radionuclides in building materials. Second, the situation of geologic structure, the surface appearing rock layer and the surface water have influence on the radioactive environment appraisal.
