Dunham, C L

Prepared for Presentation at the Hearings on Fallout before the Joint Committee on Atomic Energy, May 5-8, The rate of fall-out during the past 12 months is said to have increased to about twice the amount which has fallen out in any prior 12 months period. As much as 20 nmc of strontium-90 per square mile was measured in some parts of the United States, and substantial increases in strontium-90 contcnt were noted in milk and other foods. Large weapon testing is no longer predominantly near the equator. The AFC policy and procedures for the dissemination of information on fall-out to the public are reviewed. The presont state of knowledge on the biological effects of fall-out is summarized. The problems involved in determining permissible levels of radiation exposure are discussed. The AEC research program on fall-out is summarized. The world-wide fall-out monitoring program is described briefly. Appended are statements on the biological hazards of carbon-14, current AEC research contracts and programs in soil chemistry and mineral metabolism of plants, the AEC program in oceanography and marine biology, radiation-influced life shortening and associated effects, a status report on radiation genetics, research programs in molecular biology, and a survey on the current status of the internal emitter program.
