This document contains the Health Physics - Industrial Hygiene Report for November 1 - 30, 1948. One hundred and ninety-seven samples of air-borne uranium were taken in sixteen different work locations in accordance with the schedule previously reported (see Report #Y-138 dated 3-9-48). Approximately 23 percent of these samples gave concentrations in excess of the accepted M.A.C. of 150/ug/M3 while 28 percent showed concentrations exceeding the established radiation tolerance level of 1225 d/M3/minute in Buildings 9206, 9204-3, 9731, and 9212. Potable water, storm sewer (East Fork Poplar Creek) and sanitary sewer samples were taken regularly at predetermined frequencies and locations, and the results are included in this report. Shielding material has been installed in the Radiography Shack at 9212 amounting to one-fourth inch lead seven feet high and twelve inches of concrete eight feet high, and the radiation at the fence was calculated as 1.25 mr/hr. A study has been started correlating urinary uranium and air-borne contamination, and the study of air sampling methods was continued with the present stage being the determination of efficiencies of parallel-plate ionization chambers used for counting dust samples. A effort is also being made to reduce background counts. Air survey results taken in various buildings are included.
