This document contains the Health Physics Division Quarterly Progress Report for the period ending January 20, 1951. The work accomplished to date indicated a continuous water monitor can be constructed to have a significant reading where the activity of energetic betas is 11 dis/cc/min or more. A facility is under construction and being provided primarily for water decontamination research on both civilian and military programs, but it will also be an advantage in related waste disposal studies. A summary of progress of the Ecological Study program was given. Collision densities and energy losses from a 10-Mev beam of neutrons normally incident on a 30-cm slab of tissue were obtained by a Monte Carlo procedure. Piezoelectric frequencies of 5- and 1-megacycle quartz crystals were further tested. Work was begun on the modification of pocket meters to try to determine fast-neutron exposures. The procedure presently used for analysis for plutonium in river water is unsatisfactory because of the difficulty of separating the plutonium from iron and other inorganic constituents of the sample. Work is continuing on designs for a counter that will have a uniformly cylindrical electric field with negligible end corrections to be used with the pulse integration type of neutron dosimeter. Figures are included.
