This document contains a report for the Health Division and Biological Section of Research Division for the month of April 1946. Blood and urine analysis have been continued without any change in the last three months. Uranium slugs which had been left in the canal for about a year became spotted with a white material and was found to be due to sediment from the water. During the week of barium production Run #10 in the 706-D Building, there were 90 precipitron air samples taken by Health Physics. None of these samples indicated any significant alpha activity, but nineteen of these had beta-gamma counts greater than 1,000 c/m. Considerable construction work is getting under way at Clinton Laboratories. The old plutonium separations building (205) is in the process of being remodeled, and special safety precautions were taken in Room D which has considerable plutonium contamination. A survey revealed there are a number of contaminated articles in the scrap lumber pile. Two gamma ray monitoring films were taken at random from 35 boxes and developed, and it was estimated that over 60 percent of this shipment of films was unsatisfactory and was returned. Exploratory experiments dealing with the late effects of phosphorus (P-32) beta rays on mammalian forms have yielded some unusually interesting information pertaining to methods of controlling the destiny of cells. Rats that received single doses of 4000 to 5000 rep of phosphorus beta rays at 2 to 3 months of age now show, in addition to malignant lesions, duplication of claws on many of the toes. In guinea pigs treated in a similar manner, hair 8 to 10 times normal length replaced normal hair. These findings offer the hope that it may eventually be possible to purposefully guide cell behavior into more useful pursuits. It would appear that beta rays will be particularly useful in effecting changes in the skin.
