Current paper summaries the results of measurement of radon and gamma level inside the developing mine of Bagjata, The maximum radon level was observed to be 0.93 kBq m -3 EER which is lower as compared to the recommended DAC of 1 kBqm -3 EER. In most of the measurements, the 222 Rn concentration was lower as compared to the Derived Air Concentration of 1 kBq m -3 EER. Maximum gamma level (5.01 μGy h -1 ) was observed near the exposed ore of the mines. The results presented here will form a basis in improving the design to enhance the effectiveness of engineering control measures during operational phases. |
