This document contains the Health Physics - Hygiene Progress Report for April 1 - 30, 1949. The investigation of the alpha count method for determining uranium in urine and feces is still in progress. It has been decided that our requirements in this regard can best be served by resorting to the electroplating method of concentrating micro quantities of uranium on a thin sheet of silver. The procedure for determining amino acid nitrogen/creatinine ratios has been set up and a number of determinations have been and are being made to study normal values. A total of 150 samples of air-borne uranium were taken in 18 different work locations during the period. Approximately 25 percent of these samples gave concentrations in excess of 150/ug/M3 while 17 percent indicated concentrations exceeding an activity of 1225 d/Min/M3. A stainless steel impactor, which had been fabricated at K-25, was obtained from Oak Ridge National Laboratories and taken to Rochester for calibration. A figure and tables are included.
