GAMMA RAY MONITORING OF SEDIMENT SAMPLES.
Date of Original Version
A gamma ray transmission method has been developed to monitor changes in pressurized samples. The method permits obtaining information for sediment cores while still in the core lining, thereby eliminating several sources of error. The cylindrical sample contained in a plastic core line rests on a porous disc within a pressure vessel. A narrow beam of gamma rays is passed through the sample and pressure vessel. The attenuation of this beam is a function of sample density. By changing the fluid surrounding the sample, either consolidation or degassing tests can be performed.
