U.R; The extremely difficult puzzle of how to achieve 100 per cent sterili zation is being solved now in an extremely simple way. Or, rath er, it is simple because we're living in the atomic age. Sterilization here means ab sence of bacteria. When you coa sider that bacteria are both in visible and everywhere, you un derstand why science now con siders sterilization a "relative" matter that there is rarely if ever any such thing as 100 per cent sterilization. But now the atomic particles called electrons are being used . on a commercial and therefore i practical basis to achieve the 100 per cent, at least theoretic ally. The substances being ster ilized by electrons are drugs. First, you seal drugs into a container bottle or plastic en velope. Then you put the con tainer into a stream of electrons traveling at 175,000 miles a sec ond which gives them a charge of 2.000,000 electron volts. That's all there is to it. Fast- moving electrons pass through the "containers like light through a window. Any bacteria which may be inside are killed. Since the container is sealed, no more can get in. Thus 100 per cent sterilization becomes quite sim ple in this new "by-product" way of the atomic age. Electrons traveling at 1,700, 000 miles a second (20,000,000 electron volts) will split atoms and release the awesome and frightful power of radioactivity. At much lower rates, electrons power television tubes. At 175, 000 miles a second they're in stantly fatal to bacteria but do nothing to atoms. .That's important with drugs. If electrons broke into their atoms, the composition of the T Summer Camp Period Under Way The first of three MCA sum mer camp periods at Diamond lake started Sunday, July 24. according to Robert Jones, gen eral secretary- Donald E. Day, physical di rector, and the Rev. Kenneth Korby, board member, are camp directors for the period ending July 30, Jones said. The two. with the help of seven teen-age counselors, will conduct swim ming, canoeing, sailing, moun tain climbing, camp craft and nature study. Boys wanting to attend the camp who are without the neces sary fee may earn it by selling soap, Jones said. Two boys, Jimmy Johnson, 230 North Ivy St., and Mike Kline, 1691 Grand ave., both 10, earned their camp lee of S18 by checking out 72 boxes of soap apiece Thursday night, and had them sold by Saturday afternoon, just in time to register for camp. Jones added that earlier last week, during a special Day's Adventure trip sponsored by the YMCA, the boys had learned of the pro gram from a friend. Until then they had no way of earning camp money. Jones said. Both are now at Diamond lake. A few openings are still left for the next two camp periods starting Aug. 1 and 7, Jones said. Each period is limited to 50 boys. Brooks Boy Injured By Shotgun Blast Salem (U.R) A 12-year- old Brooks, Ore., boy was in fair condition at a Salem hospi tal today after being wounded in the chest bv an accidental shotgun blast Sunday. James Dennis Harris, was wounded by a 12-gauge weapon that accidentally fired when he tripped and fell against it while the gun was leaning against a trailer. The boy and his three brothers were shooting at tar gets when the accident oc curred, according to state police. Dead line Sunday Classified is at noon Saturday: 10 a.m. Monday for Monday: other days 5:30 previous day. if Daily's U-Drive Medford Airport drug would be changed and there might be radioactivity. The research laboratories of the Up john Company, a leading manu facturer of pharmaceutical prod ucts for the medical profession, spent five years developing a completely safe and effective sterilization by electrons tech nique. Ointments Sterilized It is now sterilizing with elec trons two ointments used by physicians in treating eye and ear infections. Ointments are very hard to sterilize by the three conventional methods heat, by the addition of bacteria-killing chemicals, or by filtration. And the closest possi ble approximation of 100 per cent sterilization is particularly important. Dr. Richard S. Schrieber, vice president and director of re search, said the electron method was "feasible" for sterilizing any phamaceutical product. Not all products require a theoretic 100 per cent sterilization and some are susceptible to theoretic com plete sterilization by the older methods. However, Upjohn has a Fed eral Drug Administration okay to sterilize such antibiotics as pencillin with electrons. Schrie ber left the impression that the method will be applied to more and more drugs as facilities are increased. The electron accelera tor now in use can sterilize only 100 drug units a minute, which pass through its electron beam on a conveyor belt.

(International) Education Board Accepts Gifts Portland (U.R) The State Board of Higher Education to day accepted SI 88,3 94 in gifts and grants for its eight corn- puses, including Atomic Energy Commission grants of S50,000 for research in experimental medicine at the University of Oregon medical school. The AEC will continue re search at Oregon State College on 2, 4-D and similar agents with 512,750. University of Oregon received National Science Foundation grants of $26,700 to study Ore gon coast prehistory, an isolated forest remnant and effects of environmental change on com munity organization over long periods of time. Large private grants accepted for medical school research were $15,000 each from International Chemical Corporation, Skokie, Hood River Youth Found Injured in Pit Hood River (U.R) Walter Baynham, 19, Hood River, was taken to a hospital in The Dalles with serious injuries yest erday after laying helpless 14 hours at the bottom of a gravel pit where he had fallen late Sun day. Bayham suffered a possible compound fracture of the left hip, a broken right ankle, a broken jaw and severe cuts and bruises when he tumbled some 120 feet into the pit. He said he was walking to Mosien when he fell. For those lone motor triris with stops few and far between, carry along a package or two of cellophane wrapped fresh Cali fornia dates.
