Disposal of radioactive wastes

Mr. Miller-Jones introduces this program on the dangers of radioactive fallout, the third in a series of exchanges between Baltimore, Maryland's station WAAM and Great Britain's BBC. Dr. Kruse explains that current incineration of radioactive waste could be detrimental to people's health if safe gas and ash levels are exceeded. Dr. Geyer and Mr. Talboys discuss the effectiveness of laundering of radium-tainted clothing. To improve removal of radioactive materials from clothing, combinations of several variables must be considered: isotopes, fabrics (fiber, weave, treatment), detergents, concentrations, water temperatures, agitation degree, and time. Dr. Renn then examines the problems of releasing radioactive waste into sewage treatment plants. Some waste, such as radiophosphorous, is easily absorbed by bacteria in the system; others could be captured by experimental trickling filters or the aerated sludge process, but the sludge must then be disposed.
