“…The ambient dose equivalent rate H*(10) (nSv•h −1 ) was reported by Sanada et al to be equivalent to the absorbed dose rate in air (nGy•h −1 ) (Sanada et al, 2020). In this research, H*(10) after deducting the contribution of cosmic rays is considered as the absorbed dose rate in air caused by terrestrial components, while the contribution of other gamma radiation sources in the air is considered negligible (Jónás et al, 2018;UNSCEAR, 2000). The theoretical formula for calculating the absorbed dose rate in air caused by the component of the cosmic rays is as follows:…”

Numbers of radioactive tailings were produced in the process of uranium mining and milling.In this study,radiation environment monitoring was carried out on a decommissioned uranium mining and milling tailings pond in northwest China, and the governance effect and operation status of the tailings pond was investigated. The soil radionuclide activity concentration and ambient dose equivalent rate (H * (10)) were measured, and soil surface radon exhalation rate was calculated. The results shown that in the tailings pond and its surrounding area, the average soil radionuclide activity concentration was respectively 238 U: 42.64±11.17 Bq•kg -1 , 226 Ra: 45.47±13.56 Bq•kg -1 , 232 Th: 33.30±7.33 Bq•kg -1 , 40 K: 631.33±72.05 Bq•kg -1 , the average H * (10) was 63.32±6.46 nSv•h -1 , and the average radon exhalation rate was 40.46±11.29 mBq•m -2 •s -1 .Radionuclide activity concentration, H * (10) and radon exhalation rate were within the range of world natural background. Spatial distribution of radioactivity was analyzed by OK interpolation based on the investigated data. According to the measured results and spatial interpolation analysis,the decommissioning governance effect of the uranium tailings reservoir is good, the operation is normal, and there is no migration or diffusion situation of radionuclides in the pond has been found.

The Bakony is one of the most active areas in Hungary. Not only is the region home to several popular hiking destinations, but its industrial activity is also significant. On this basis, it is important to carry out a comprehensive study to assess the radioecological status of the Bakony. In this study, 12 monitoring points were selected to collect environmental samples over three different time periods. The samples were analyzed by gamma- and alpha spectrometry. Although the concentrations of Th-232, Ra-226 and K-40 closely resembled the worldwide averages, that of Po-210 in the vicinity of human activities was elevated.
