The utility of radar equipment in measuring surface precipitation was investigated. A summary of the operation of raindrop cameras is given. Satisfactory operations of one year of raindrop cameras at Miami, Florida; Corvallis, Oregon; Majuro, Marshall Islands; and Woody Island, Alaska were obtained. The means of reducing raindrop data is reviewed. An automatic M cards means of transferring measurements from the projection table to results Some reviewed. is data drop the of was built. Preliminary analysis are given from the Miami data. A summary of the problem of rainout is discussed.

Transactions of the Second Seminar on Biological Problems in Water Pollution, April 20-24, 1959 Donaldson, L.R. Univ. of Washington, Seattle Publication Date: 1959 7p. Publ: Robert A. Taft Sanitary Engineering Center Journal Announcement: NSA15 Document Type: Book Analytic Language: English The results of successive studies over a period of twelve years have shown that biological activity is often of greater importance than physical factors in the distribution and localization of radioactive products in a Marine environment. Certain organisms, notably algal and planktonic forms, remove minerals from the water within hours. Much of the uptake is by absorption. The amount of uptake by inventebrates and fish is primarily dependent on feeding habit, indicating the impontarce of food chains in the distribution of radioactive materials. Biological effects directly attributable to the injurious effects of radioactive contamination have not been evident. Competition is so severe that any injured individuals are lixely to be eliminated and replaced before they are observed. It is clear from the rapidity of uptake of radioisotopes that there is a great thirst for minerals by organisms in the marine environment. The practical implication, therefore, is that fertilization of specific areas with mineral products could overcome one of the limiting factors to biological productivity. Under some conditions suitable isotopes could be used as an index of the efficiency of such fertilization.

Brookhaven National Lab., Upton, N.Y. 5003583 Subject Codes Publication Date: Sept. 1960 86 p. Primary Report No.: BNL-609 Journal Announcement: NSA15 Document Type: Report Language: English Annual medical surveys of the people of Rongelap Island were carried out in March 1959 and March 1960, 5 and 6 years after their accidental exposure to fall-out. During the 1959 survey 76 exposed adults and 166 unexposed persons, (and their children) who served as a comparison population, were examined. In addition, groups of children at nearby atolls were examined as controls for the growth and development studies on the exposed Rongelap children. In 1960 only the exposed people were examined. As a result of their exposure in 1954, many of the Rongelap people experienced early
