The Magnetic Susceptibility/Induction Conductivity/Gamma probe is designed for measurement of magnetic susceptibility, electrical conductivity and background radiation of rocks in boreholes. High sensitivity, stability and wide dynamic range make it possible to carry on precise measurement of magnetic susceptibility and conductivity in metaliferious and sedimentary geology i.e. - sand - clay layers and ore zones. Thanks to the induction method the probe can be used in water filled, dry and plastic cased boreholes. The response of the probe is practically instantaneous (<0.5s)
Natural Gamma is principally used because it can be recorded in boreholes of any condition (dry, cased etc), it is an excellent indicator of lithology, and has a sharp thin bed response. The response of the gamma ray can be specifically calibrated in terms of ore grade uranium content.
