Radioactive Techniques
Radiometric Surveys
Outline
Radiometric surveys involve the measurement of gamma radiation resulting from natural radioactive sources. Instruments are available to measure either total count or provide spectral information on individual elements such as uranium, thorium and potassium in order to identify specific sources of radiation. Modern multispectral meters capable of measuring up to 256 channels are being increasingly used in environmental mapping. Radiometric measurements are primarily used in mineral exploration but can also be applied to the detection of faults, location of caves and for mapping contamination.
