The new Cobalt-60 gamma-ray irradiator, recently installed at the Davis campus, is designed specifically for biological research. The first application of the new facility involves a study of possibilities for extending the storage life of fruits by irradiation. The irradiator has also been used in studies of genetic mutations and breeding programs for agricultural products. Desirable features for research include a large, uniform radiation field, temperature control, atmospheric modification, and safety of operation. Ten feet of de-ionized water in this pool-type unit maintains a constant radiation barrier against the 32,500 curies of Cobalt-60. The unit is one of the largest of its type in existence.
