Abstract
A study was made to determine the effects of bulkheading on radon release from an underground uranium mine during both exhausting and blowing ventilation. The continuous radon measurements were made with and without a large portion (about 40 to 45%) of the mine totally or partially bulkheaded for consecutive periods of up to 2 weeks. These measurements showed that bulkheading produced a major effect on the total radon leaving the mine and that this effect was dependent upon the type of ventilation and the integrity of the bulkheads.
