Series Description: This report summarizes the Reactor Technology Division's efforts to determine the sources of onsite atmospheric radioactive contamination during 1948-1949, including RaLa operation fume lines and iodine-131 and -135 recovery operations. Sampling equipment consisted of CWS filter paper designed to remove particulates. The filters were placed in stream flows of the facilities. Results are reported only as potential contamination levels. Gamma activity levels were the prime focus of the investigation. Results are given in millicuries/hour (mCi/hr), microcuries/cubic foot (mCi/f3), counts/minute/square inch (c/min/in2), and curies per day (Ci/d).

Data Elements: 88, 103, 116, 119, 124
