Description/Abstract:
This document contains the Health Physics Division Quarterly Progress Report for the period ending July 20, 1951. Detailed studies of conventional and modified water-treatment processes were continued on a laboratory and also a small pilot-plant scale. Progress during the period in studies by the staff of the Ecological Study program were discussed. Experimental investigations were initiated to measure nuclear radiation by observing the frequency variation of an RF oscillator in conjunction with an electrometer whose capacitance varies as a function of applied charge. A survey of analyses of urine for fission products conducted at the Laboratory during the last two years reveals that, where measurable amounts of activity were found, it has been due in most cases to the radioisotopes of strontium. The first model of a thermal-neutron survey meter was completed and turned over to the Survey Section for field tests. A test probe for measuring slow neutrons in drill holes is being built. Exploratory flight tests were made over a 6-curie Cobalt-60 source and isodosage curves constructed which indicated that a light aircraft flying at low ground speed and at an elevation of 500 to 1000 feet could be used with commercially available Geiger-Muller survey equipment to locate such point sources. A table and figures are included.
