Radon emanation from stopes backfilled with cemented uranium mill tailings. Report of investigations/1982

Technical Report ·
OSTI ID:6508418

An experiment was conducted by the U.S. Bureau of Mines and the Canada Center for Mineral and Energy Technology (CANMET) to measure the emanation rate of radon from cemented unclassified mill tailings in two dewatered stopes of a uranium mine at Elliot Lake, Ontario, Canada. The radon was monitored upstream and downstream and in both stopes to determine the concentration in the stopes and the amount exhausted from both stopes. The emanation rate was determined to be 0.55 pCi/sq cm/sec from the mill tailings, which is approximately 1,000 times higher than the average flux in the mine before backfilling.
