Study on radon eduction rate for remediation and decommissioning of uranium tailings impoundment
Description
The author studies the measurement, calculation of radon eduction rate and the control to radon eduction rate by covering some material in big area of tailings for remediation and decommissioning of uranium tailings impoundment. In order to eliminate the effect on the measurement of radon eduction rate by the weather and the inhomogeneous radium content of tailings, the suitable measuring time, network and times should be considered in the measurement of the average annual radon eduction rate of uranium tailings. It is proposed that the better economic and social benefits will be obtained with natural material (soil, gravel etc) as cover material to reduce radon eduction rate. The author describes how to determine the cover thickness by comparing the results in site test with that in calculation
