On the influence of uranium ore emanation into the borehole on gamma-ray logging results
Abstract
Partial escape of radon into the borehole, subjected to prolonged flushing during drilling, leads to a decrease in the intensity of radiation along the borehole axis and an underestimation of linear uranium reserves from gamma logging data.
