This document contains a Health Physics Division Quarterly Progress Report for the period ending July 15, 1950. There was concern with the instrumentation problems of monitoring a municipal water supply and preliminary specifications considered for the monitoring instrumentation were listed. A series of laboratory jar-test experiments on coagulations and precipitation processes to study the removal of individual isotopes was completed. Organization and planning of the Ecological Study to be conducted by the Tennessee Valley Authority has proceeded actively and is essentially complete. An attempt is being made to derive an analytic formula for the effective atomic number of a substance to be used in the calculation of a mass absorption coefficient for gamma rays. It is expected that the scintillation counter will replace present Geiger counter equipment in the Geological Survey DC-3 airplane for aerial uranium prospecting. Comparisons were made between absorption of beta radiation as measured with an end-window beta counter and as measured in an extrapolation chamber, and it was found that the absorption was larger for the ionization chamber in every case. One person is presently engaged in the development of a procedure for determining radioactive phosphorus in body fluids.
