Geologging tungsten gamma radiation shielding
geologging is an exploration technique used mainly in the oil and gas industries. It is also known as wire line logging and borehole logging. A gamma ray source is lowered into a borehole and the radiation penetrates the rock strata. This data can then be analysis to determine whether deposits of gas or oil are present. Tungsten alloy is used to shield the radioactive source and to act as a collimator for the gamma beam.
Industrial radiography uses gamma radiation to detect structural faults in materials such as metal and concrete. As with pipe-line inspection, the equipment uses tungsten gamma radiation shielding, coupled with a tungsten collimator.
