70 INDUSTRIAL APPLICATIONS the Army Pictorial Center. For information about sale of prints, inquire at the Audio Visual Branch, Division of Public Informa- tion, USAEC, Washington, D. C. 20545. Preservation of fresh fruits and vegetables by radiation pasteurization is described in this semi-technical film. After touching briefly on the high spoilage losses presently encountered in the marketing of fresh produce, the film presents graphic visual evidence of the reduced spoil- age and extension of shelf life which can be obtained through the use of nuclear energy. The process of exposing foods to the energy of the atom in radiation research facilities is described, together with a simple animated version of what happens during exposure. Emphasis is placed on the fact that foods processed in this way are safe for hu- man consumption, and that each radiation pasteurized food item will be approved by the U. S. Food and Drug Administration before it is offered for sale to the public. THE FRESHER THE BETTER (1966). 13 l / 2 minutes, color. Produced for the USAEC's Division of Isotopes Development by the Army Pictorial Center. For information about sale of prints, inquire at the Audio Visual Branch, Division of Public Informa- tion, USAEC, Washington, D. C. 20545. Preservation of fresh seafoods by radiation pasteurization, to extend refrigerated shelf life up to three times that of unirradiated fresh sea- food, is described in this semi-technical film. The concept of using energy from atomic particles to kill or destroy microorganisms and other food spoilage bacteria is described in animated form, followed by sequences of actual research being performed. The Marine Prod- ucts Development Irradiator, a semi-commercial scale food irradiation facility, is shown as products are being processed. The purpose of the film is to introduce the concept of radiation preservation of food, and to explain the process and its results. Emphasis is placed on the fact that foods processed in this way are safe for human consumption, and that each radiation pasteurized food item will be approved by the U. S. Food and Drug Administration before it is offered for sale to the public. THE NUCLEAR WITNESS: ACTIVATION ANALYSIS IN CRIME INVES- TIGATION (1966). 28 minutes, color.

The scientific crime investigator is ever searching for new and better techniques for the examination of physical evidence involved in crime investigations. This film describes, in a fascinating and non-technical manner, one of the most exciting new techniques in this field — a nu-
