1. Uranium prospecting methods

1.1 Direct methods

They are based either on the radioactivity of a uranium descendant, or directly on the chemical content of uranium in water or rocks.

The method that uses radioactive properties is radiometric prospecting; the one that directly measures uranium concentration in water and alluvium is geochemical prospecting.

The radiometric measurement operation carried out in a borehole is called radiocoring, and its recording is called logging.

One of uranium's descendants, radon, is a radioactive gas, which is easily detected by devices known as emanometers. The radon prospecting method is called emanometry.

Helium-4 prospecting, which comes from the decay of uranium nuclei and some...
