Originating Office: Health Physics Division Finding Aids: ORNL Register 1-4397, 1948-1969 Disposition AuthorityUnscheduled Series Description: This record series consists of four progress reports documenting efforts in 1948 and 1949 to detect the source and measure the level of radioactive particulate contamination in and around the X-10 area. Special attention is given to the 706-D building that housed RaLa production. Monitoring data is reported in beta and gamma decay in counts per minute and particles per frame per twenty-four-hour period. While the reports are particularly concerned with uranium-oxide particle contamination, they also mention iodine-131 and xenon-135 particle contamination, especially during RaLa production. The reports provide information concerning wind direction and velocity, dates and times of monitoring, and filter collections and analysis. For the 706-D building, the number of slugs dissolved per RaLa run is given and this information is correlated with monitoring sample data.
