WESTERN presented an extensive discussion of the various factors which might be used in determining the potential hazard from fallout. He traced the various factors affecting the eventual deposition of strontium 90; including, end stratospheric fallout, radioactive material on plants as well as uptake through the STRONTIUM-90 soil, radioactive material in food products and the FALLOUT PROBLEM amount appearing in human bodies. In this discussion he included consideration of Cs-137, Ce-144, rare earths and plutonium although at present strontium 90 appears to be the only material of concern. DR. TOTTER presented the plans for the symposium to be held at Brookhaven this Spring. It is expected that foreign representatives from Central and South America would attend and approximately onehalf of these would be in the field of biology and INTERmedicine. The invitation to attend and present talks AMERICAN presented a delicate matter of diplomatic and scientific CONGRESS relations.
