Radiation Engineered Services, Lafayette and Water Sts., Norristown, Pa., a new engineering firm, is now of fering a series of training programs in the nuclear field. These programs are designed to assist in obtaining Atomic Energy Commission licenses for the possession of radioisotopes, and to pro vide a source of information for those interested in the nuclear field. Typical programs included : basic and advanced isotope radiography, basic and applied nucleonics, isotope gaging, and tracers and radiochemistry. The programs will be offered in the RES building in Nor ristown, Pa. (near Philadelphia), or, on special arrangement, can be conducted in the customer's plant. Periodically, certain programs will be offered in ma jor cities throughout the country. Technical Measurement Corp., manufacturer of radiation measure ment instruments, recently moved all operations into a new plant in North Haven, Conn. The company was formerly located in New Haven. The new building provides over 11,000 square feet of space and houses all engineering, production, and adminis trative departments of the company. The 3-acre site will permit extensive future expansion.
