Geiger-Muller Counter

The Geiger-Muller Counter is reliable for detecting radioactive material but is not useful for determining the real value of the deposit. A rock formation can show an increase in the counts if the rock is hold near to the counter because the rock could have any residual radioactivity. If we want to know the real content of thorium or uranium it is necessary carry out chemical analysis. The counter is the most popular device for prospecting uranium, but is not the unique. If a virgin photograph film is left over a radioactive ore for one or two days in a closed recipient where the light can’t have access, the film will be developed. The ultraviolet lamps are an auxiliary device for searching some types of secondary minerals of uranium.
