UEP42: Uranium Exploration

The UEP42 probe provides a set of data parameters responding perfectly to the needs of both uranium exploration and in-mine grade control. The probe is equipped with two complementary high and low sensitivity gamma radioactivity sensors to allow reliable results to be obtained over a wide range of uranium concentration values.

In addition, the probe provides borehole inclination and azimuth, as well as a focussed resistivity / chargeability measurement for the detection and evaluation of alteration zones.
