This document contains the Health Physics Progress Report for January 1, 1952 to July 1, 1952. Construction of the new health physics facilities is under way. Air analysis data showed effective control measures where beryllium and its compounds are handled. Mercury contamination is fairly well controlled. An evaluation program of hood design and performance was planned in an effort to reduce uranium contamination from machining operations. Preliminary data indicated that a central air cleaning system for normal operations would be capable of handling the low loadings effectively. Information received at Kettering Laboratory was useful in setting up a method for the determination of mercury in urine. The digestion apparatus was modified and procedure simplified, and out of about 100 routine determinations made, all but one showed concentrations below 0.3 mg/liter. The use of an explosimeter showed concentrations of hexone in the air of Building 9211 do not create a fire hazard. Finger rings with screw caps are now being used to measure hand exposure, and the fluorometric analysis of urine was resumed on May 1. An extensive uranium air analysis program was continued in plant areas where highest levels of air contamination existed. A study of results show a decline in the levels of air contamination between the first and second quarters of 1952 due to (1) transfer of a large section of operations to a new area; (2) installation and more effective use of hoods and other localized ventilation; and (3) improved housekeeping and operating techniques. The activities during this report period centered, primarily, around the extended shutdown of the 86-inch cyclotron.
