To control the waste from ra- dioactive materials used on the University campus, the Radiologi- cal Safety Department headed by Prof. Gerald M. Ridenour, out- lined a complete program of con- trol procedure. The objective of the department is tq protect the isotope user, his associates and the community as a whole. o This is -accomplished by a series of steps, according to Prof. Riden- our. First of these steps is the re- qtiirement that all radioactive ma- terial to be used on the campus m'ust first go through the radio- logical Safety Department, located in the School of Public Health. Materials Checked Here it is monitored to check hazards which might have been incurred through the handling of the package during transportation' to the University. The radioactive material can go to a number of laboratories, such as the University Hospital, phys- ics, natural science, pharmacology, or chemistry departments, and the Engineering Research Institute, the Fission Products laboratory, or the Medical School. , The physical set-up for the use of the material and the qualifica- tions of the user are approved ' by the safety department to be sure 2 color-coordinated PALM BEACH* suits that facilities and workers are protected from the material. Danger of radiation from these materials is lessened by proper de- sign of laboratory or working area facilities. This prevents direct ra- diation effects or ingestion of ra- dio-active material on the worker or his immediate associates. Safety Techniques Used In these departments the use of personal monitors, shielding, and cleanliness techniques and safety preventatives are also employed. After the radioactive materials are used, any waste, liquid or solid, from the operation comes back to Radiation Control Center again. In this way ,the department has complete control of the material flow through the University from its receipt to ultimate disposal. When the waste reaches the of- fice, it is ready for waste classifi- cation. There are two broad cate- gories: short-time decay for ma- terial that will decay out to a safe level in a short time, and long- time decay for material which re- quires a long time to decay before it is safe. Short-time decay wastes can be stored in bottles or vessels in a storage area. The volume of ra- dioactive material is not large be- cause the material is spread in small volume throughout. If the decay period is very short, the department just lets the ma- terial decay out. Then it is dis- posed in a harmless form into san- itary sewers if it is a liquid. If a . 1 POSITION OPEN Ulrich's Book Store has an opening for an ambitious young man to learn the book store business- an excellent opportunity with a good future solid, the material is thrown out in land fill operations or may be incinerated. Long-time material can take up to fifty or more years to decay. If this were stored, it would gradually pile up until it became a nuisance. The Atomic Energy Commission has burial grounds throughout the country for the disposal of this long-time material. The solids are packaged and taken by a special truck to the iso- lated burial grounds. They may also be disposed in the ocean. Liquid To Solid Liquid long-time waste can be made into a solid by mixing them with concrete and then disposed. One operation that we will soon have here according to Prof. Rid- enour, is that we will be able to take care of heterogeneous types of wastes in one operation. It is difficult to treat these wastes with one chemical process, he points out. It has been discovered that these wastes can be treated by means of ion-exchange resins which take out all the chemical ions. When the ions are taken out to the extent of their capacity, these materials are reduced to a more compact form. These resins are disposed of by burial or by mixing them with concrete. This whole operation is time consuming and costly, but is necessary because these materials, cannot be treated with one chemical. Isotope Determines Treatment The type of treatment for the isotope depends upon the chemi- cal nature of the isotope con- cerned. This. has proved to be a big problem as well as the prob- lem of reducing the volume. It follows that the smaller the volume of material, the easier it is to handle, and the cheaper it is to treat. Another problem that the Radi- ological Safety Department must handle is that of keeping the ra- dioactivity level of the environ- ment at a point where it is not go- ing to affect anyone. "We have adequate control of the situation by the specific con- trol of each step as the material goes through the University," Prof. Ridenour says. "We also have con- tinuously recording monitoring machines that will detect any slip-up in control operations im- mediately." He continued, saying that radi- ological material can get into the surrounding environment in two ways, via the air and sewage. Machines Add Protection Continuously recording air and sewage monitoring machines that will detect the escape of even sub- dangerous levels of activity into the environment protect the Uni- versity surroundings from radia- tion danger from thesc wastes. Prof. Ridenour continued saying that the University will soon have many more of these monitors to insure adequate control with the beginning of the operation of the reactor and other projects on the North Campus. In addition, the University has cooperated with the State Board of Health and State Stream Con- trol Committee in maintaining correct operations for the disposal of the wastes.

Brownell's accusation that the Labor Youth League is a Communist-front organization is part of Alita Letwin's job. Mrs. Letwin, secretary of the national LYL Student Council, is currently visiting LYL organiza- tions in the Midwest. She was in town yesterday to examine the campus organization. "The LYL, under the Internal Security Act of 1950, has just been ordered to register as a Commun- ist-front organization by the Sub- versive Activities Control Board. We are now appealing our case before the Circuit Court of Ap- peals," Mrs. Letwin said. "We have been accused of sup- porting policies advocated by the Communist party," she continued. "These include opposing armed in- tervention in Korea and Formosa, supporting a cease fire, seeking in- ternational control of atom and hydrogen bombs, and supporting civil liberties. Matusow Report "Many organizations have tak- en similar positions' on one or more of these charges. Under the McCarran Act, we could be ac- cused on any one of these counts." Mrs. Letwin claimed that the Subversive Activities Control Board had based its report on informa- tion given by Harvey Matusow. "Matusow later denied all of his previous statements, but the Board decided to ignore the denial," she commented. Mrs. Letwin, who graduated from the University of Wisconsin in 1954, became interested in Marxian doctrine. as a college freshman. She joined. the LYL, serving as chairman of her local organization for two years.

The islands, however, are only incidental to the main issue now developing in the Pacific-control of Formosa Strait and the air above it. Seventh Fleet Defense Up to now the control of the wa- ter barrier between Formosa and the mainland has been in the strong hands of the United States 7th Fleet, with an assist from the Chinese Nationalist navy and air force. The U.S. has used its control to try to prevent war. The Reds, on the other hand, openly admit they intend, when they can, to "liberate" Formosa. Even in offering to open negotia- tions with the United States, Chou specifically reserved what he called the Red Chinese "right" to per- form this "liberation." The reason the Communists haven't carried out their bellicose threat long before now is their in- ability to cross the strait. But the situation is now changing to a degree where the U.S.-Chiang con- trol of the straits can be chal- lenged by land-based air power. Post-War Activity The changes in Communist ca- pability near Formosa began some- time after the Korean War ended. It is obvious that by using new jetworthy concrete strips complet- ed or in final stages of construction in the central coastal area, the Chinese Communists could extend their air threat to the whole of Formosa Strait. How does Matsu and Quemoy fit into this picture? They lie on the entrances of two of the best central China harbors -Amoy and Foochow. As long as the Nationalists operate from them the amount of shipping going into these ports is limited. Clean them out and jet fuel which now must be smuggled expensively up the coastline in junks or hauled labor-. iously over bad roads can be shipped in by small tankers. Ar- mies anchored to defense posi- tions off these islands would be free for more aggressive mischief. These, of course, are only the military consequences which would follow if the islands were lost. The Chinese say the worst effect would be on morale-that non-Commu- nist Asiatics everywhere are get- ting wary of Western retreats in Asia and with their lifelong habit of trying to stay on the winning side are beginning to veer toward communism. There is no doubt the bloodless surrender of the Tachens gave the non-Red parts of Asia a shock. But the real issue is control of Formosa channel water and air. From the U.S. viewpoint, if such control can be maintained without the offshore islands they can be written off. No one can quite an- swer the question whether these islands are vital to such control. Everyone agrees, however, that channel control would be firmer with the islands in friendly hands.

International Affairs Discussing international affairs, the 22-year-old Mrs. Letwin dem- onstrated a serious interest in her LYL work, only occasionally show- ing her flashing smile. "We op- pose German rearmament because we feel it would be an: army aimed at offensive and not defensive measures. Even Chancellor Ade- nauer has indicated this," she said. "We also oppose intervention in Formosa. Formosa has tradition- ally belonged to the Chinese peo- ple. It is 7,000 miles away and it is hardly proper for us to be de- fensive at that distance." Mrs. Letwin pointed to the Ban- dung conference as an "example of the strength of the Asian and African peoples. It is the first time that representatives of three-fifths of the world's population have openly sought peace." A history major, Mrs. Letwin now devotes all of her time to her LYL job. For relaxation, she plays the bassoon and piano, skills ac- quired at the New York High School of Music and Art. Another project entails working for the national 18-year-old vote.
