RADIOMETRY
Radiometry measures certain energy Windows associated to unstable isotopes, therefore there can be done certain determinations relative to radioactive elements concentration associated to minerals in rocks, soil and solution in the first dozens of meters on the ground.
Multichannel spectrometer not only detect photons Y but also determine their energy and carry out a statistical register during the sounding time, which can vary from 1s to 9999s. The sensor normally used is sodium lodide (Nal) as sensitive gamma element. With this kind of spectrometers, a Geophysic can determine the radiogenic contributions from uranium, thorium, potassium and any transition unstable element from the group Y, being able to determine lithological aspects, soil geochemistry, etc.
It is an excellent method for exploring minerals to discriminate volcanic units from sedimentary volcano, as well as identify through potassium content, argillic alterations. The Th high content are great tracers in rare earths deposits. In the uranium deposits prospection, radiometry is absolutely important to any type of deposit model.
In environmental monitoring, it is used to detect chemical alterations caused to the soil by the action of pollution elements or the detection of fluid with substances with some kind of transmitter, recognize areas exposed to the presence of argon, radon and other radiogenic element.
