SJ Geophysics Ltd. - Contracting Services:
Radiometric Surveys
Applications:
- detect anomalous concentration
- detect radioactive ore deposits
Examples:
- mineral exploration
- logging oil welts
Scintillometers are used to detect anomalous concentrations
of radiation. Only gamma radiation is useful in exploration because alpha
and beta emissions are masked by a thin cover of soil, water, or air.
As gamma ray emissions penetrate only a few inches of soil or a few hundred
feet of air, the radioactive ore deposit must virtually outcrop at the
surface to be detected.
