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