RADON MEASUREMENTS IN AND AROUND SOME GOLD MINES IN SHWE KYIN
Abstract
- The aim of this paper is to carry out the radon concentration. In this research, radon concentration in five soil samples collected from different depths at Kalain Ravine are recorded by RAD 7 radon detector as 415, 8.20, 16.4, 13.1 and10.9Bq/m3 respectively. At5 ft depth, the recommended remedial action has to perform in less than 3 years and underneath this depth, there is no action required. Collected soil samples were also examined with energy dispersive X-ray fluorescent spectrometer. In addition to the standard feature of identification of all elements sodium (Na) to Uranium in a sample, quantitative information is provided. In these samples, it was observed that the main constituents in all samples Si, Al, Fe, K and S. Potassium was detected in all samples which can contribute to K40 activity. The pore space in soil grains might contain water and if the radon atom terminates its recoil in the water, the radon might be transported to water around mining sites (mine dump, mine tailings or ravine). Water samples were collected and analysed in laboratory to record radon concentration also with RAD7 detector. It was found that the radon concentration in water samples from Kanni tailing dam and Kyet Khat Kali spring were 4.84 pCi/L and 2.68 pCi/L respectively. The water samples were analysed with Atomic Absorption Spectrometer (AAS) to be see the concentration of particular hazardous elements (Pb and K). It has been obtained that in water samples from both sites no trace of lead was found. Potassium contents in water samples from KyetKhatKali site is 1.53 mg/L and that from Kannitwin is 0.99 mg/L.
