APPARATUS AND PROCESS FOR MEASURING GAMMA RADIATION FROM A RADIOACTIVE WASTE CONTAINER

摘要

The gamma fluence of a container holding radioactive waste material can be quickly and easily ascertained both as to energy and quantity by using a multisegmented detector. The device comprises shielding with a plurality of openings, each containing a detector that measures the radiation from a portion of the container. Simultaneous output signals are obtained from the detectors and combined to obtain a representative gamma fluence for the total portion of the container measured. The container is then rotated to measure around the entire container and yield further signals. These signals are combined to obtain a total gamma radiation fluence from which the contents of the container can be determined.
