Abstract:

A description is given of a gamma-ray spectrometer complex consisting of four interchangeable, low-background NaI(Tl) crystals that operate simultaneously. The system is used in determination of concentrations of natural radioactive elements and sedimentation rates of bottom sediments by the ionium method. Three detector sizes are used, depending on amount of material available: 80x80; 100x100, and 150x150. The system is operated clockwise and data are brought out on a punch tape; results are computer-processed. Examples are shown of the complex use in determining sedimentation rates of bottom sediments in the Southeast Pacific and concentrations of natural radioactive elements in DSDP Hole 381.
