Uranium prospecting method

摘要

A technique of applying the thermoluminescence phenomenon to uranium prospecting. The thermoluminescence of specimens of quartz isolated from field samples is measured. The samples are then irradiated at several levels, and the thermoluminescence of the samples is measured at the various levels. This enables a determination of the natural radiation received by the samples The current radiation from the samples is measured with a dosimeter, and by using both shielded and unshielded dosimeters the type of radiation from the samples can be determined. Knowledge of the total natural radiation received by a sample and the current rate of radioactivity allows the determination of the present position of uranium or other radioactive source and its geological "migration" path.
