This document contains the Health Physics Progress Report for November 1, 1950 to December 31, 1950. In connection with the work in the uranium industry, there is planned and in the process of being implemented, a long-range program to study the chronic effects of long term inhalation exposure to minimal and sub-minimal concentrations of uranium and its various compounds. Three general sources of radiation recognized at this site are: radio-active materials, accelerators, and experiments with critical masses. Plans have been made to construct a remotely controlled system for the removal of "hot targets" due to a serious health physics problem associated with the cyclotron. The experimental Criticality Laboratory set-up for monitoring has been partially completed and limited operations have been started. The calutron, for the first time, will be used to separate the isotopes of Plutonium and facilitate more accurate measurements of their nuclear properties. Two changes effected in the electroplating apparatus used in uranium urinalysis are: (1) the modification of cells making them rugged and easy to disassemble and clean; and (2) constant speed motors will replace variable speed stirrer motors. The activities in which the Industrial Hygiene Section are presently engaged are: air-analysis program involving beryllium and its compounds; appraisal of non-radiological health hazards through air sampling; coordination of air sampling program with preventive engineering measures; testing of ventilation systems with air flow measuring instruments; and consultation with safety and engineering departments and other interested groups on equipment selection and design where health hazards may arise. Tables and figures are included.
