2-A Sun., Nov. 30,1975 THE SHREVEPORT TIMES (Times Photo bv Bob Reeder) Dr. Henry W. Julius Researcher Is Concerned With Nuclear Effect By Elaine King Of The Times Staff Dr. Henry W. Julius of The . Netherlands is concerned about the effects of radiation on humans, an interest he shares with Dr. George R. Meneely of Shreveport, with whom he is visiting through Tuesday. Dr. Julius will visit Louisiana State University School of Medicine in Shreveport, where Dr. Meneely is professor of physiology and biophysics and medicine, and head of t h e d e p a r t m e n t of physiology and biophysics. While in the United States, Dr. Julius is visiting several sites where work with radioactive materials is underway. In The Netherlands, Dr. Juilius is associated with the World Organization for Applied Scientific Research, a special organization involved in any field involving society from "fire prevention to cancer resear-ch and many things in bet-ween," he explained. His work is with the Radiologic Surface Unit TNO. The TNO is important, he said, because it is the abbreviation for the organization in Dutch. His native land is really the only country with an organization such as TNO, he said, although Brazil is interested in forming an organization. His father was director of TNO and visited Brazil to discuss problems involved with building such an organization with Brazilian officials, he noted. The physicist works with whole-body counting, which determines the radioactivity level in the human body. "If you want to measure radiation at a very low level, you can only do so behind a shield," Dr. Meneely explained. In whole-body counting, a shield filters out extraneous sources of radiation in the environment to permit the amount of radiation in the body to be accurately measured. "Perhaps the main activity of his unit, Dr. Julius said, "is in the field of personal monitoring." Dr. Julius has been involved in developing a detector to serve as a per-sonal dose meter. In simple terms, the detec-tor stores radiation and when warmed it emits sparkles of light. The amount of light emitted is proportional to the amount of radiation that struck the detector, Dr. Meneely said. "We are doing all this for the protection of personnel," Dr. Julius said. A secondary benefit will be the statistical information gathered from the findings that will enable the scientists "to get a firm impression of what's going on in nuclear power plants" in regard to radiation exposure. The country has two nuclear power plants and the workers at one will begin wearing the detectors by January or February. "Up to now we are still using film badges in Holland" to detect exposure of workers to radiation. Dr. Julius said. But it won't be much more than a year before the switch to the more sophisticated cietector is made, he predicted. The detector "could be one of the most sophisticated available," Dr. Julius said. In The Netherlands, the law requires a check of the detectors every two weeks to determine exposure to radiation. In most countries the average time between checks is a month, he said. Although workers at a nuclear reactor plant will begin wearing the detectors, the number of persons working with radioactive materials in nuclear reac-tors is less than in other areas such as medical fields. Developing the detector is a "rather high priority," in his country the scientist said. And it represents a rather advanced detection method compared to the one he used in 1937 when the custom was to attach a piece of dental x-ray film with a paper clip to the clothing and if the paper clip was visible on the film it meant too much exposure to radiation, Dr. Meneely recalled.
