News & Views Califomium-252 Meeting The Atomic Energy Commission will hold its third californium-252 utiliza tion meeting with industry on May 24 and 25, 1972, at the Sherman House Hotel in Chicago. These meetings are designed to explore the ways that cal ifornium-252, an intense neutron emit ting isotope, can be used in industry, medicine, geology, petroleum, agricul ture, space, and education. The radio isotope is a man-made material which is a by-product of the production re actors at AEC's Savannah River Plant. About 39 organizations are now using the isotope in experimental programs, and results are published regularly on these studies by AEC. Among the top ics to be discussed at the Chicago meet ing is the establishment of a californium demonstration center at Louisiana State University. Also to be covered are 19 possible end uses. Eastman Kodak is one of the com panies which is using californium-252 experimentally. The company has a two-year program to develop new acti vation analysis methods and to test the feasibility of using the radioisotope for chemical analyses. Other companies are also exploring analytical possibilities of californium-252. Eastman Kodak's contract with the AEC calls for the company to "evalu ate the feasibility and practicability of thermal and fission-spectrum activation analysis" in testing for the presence of fluorine, bromine, chlorine, iodine, so dium, aluminum, silver, and cadmium. Edwin P. Przybylowicz has overall di rection of the Kodak project. Persons interested in the analytical possibilities of californium-252 are urged to atend the utilization meeting and learn about the special properties of the isotope that make it of potential use in analysis. To attend the meeting, write or call the Manager, Savannah River Operations Office, P.O. Box A, Aiken, SC 29801, 803-824-6331, ext. 2252. Plastic Ir Detectors Recent experiments at the National Bureau of Standards have shown that treatment of polyvinyl fluoride by pres sure, heat, and dc voltage will produce a sensitive infrared detector. The piezo characteristics are formed by rolling the material and then simultane ously applying a high dc voltage, pres sure, and heat. An NBS team com posed of Julius Cohen, Seymour Edelman, and Carol Vezzetti has processed polyvinyl fluoride and polyvinylidene fluoride as well. Processing takes place by clamping a sheet of material between the plates of a hot (60° C) press (800 54A
