During the past five years the number of sea and freshwater samples collected by the (DFR) for radiocaesium analysis has increased significantly due to the extended monitoring programme following the Chernobyl accident. Counting times have increased because of the general reduction in levels of radioactivity following the introduction of a new effluent-treatment plant at British Nuclear Fuels's reprocessing plant at Sellafield. The large number of samples and the low levels of radioactivity have resulted in the requirement for an additional, highly sensitive, gamma counting system. This paper describes the design and development of an improved automated gamma counting system suitable for the determination of low levels of radiocaesium activity in these samples. (author).
