According to the provinces, municipalities and autonomous regions, coal mines and coal gangue kind of natural radionuclide content measurements, Inner Mongolia Erdos camp area where the uranium content of coal samples was 6.3-57.7 uranium-238 becquerels per kilogram coal gangue content of 14.6-87.2 uranium-238 becquerels per kilogram, compared with the national average at the same level. Inner Mongolia Camp uranium, and coal mines around at different depths, coal mine uranium at about one hundred meters, which is currently untapped uranium, coal and uranium mining nor under. Second decade of environmental radiation levels did not change significantly. China has set up in all the provincial capital cities and some of the 167 prefecture-level city level radioactive air automatic monitoring stations, continuous monitoring of air gamma dose rates, continuous air aerosol samples were collected party 'î‡\xAD mother Qiang îƒ\x95 intestinal worm called
