Series Description: These monthly radiation reports from 1947 contain monitoring and sampling information for various ORNL work locations, including the 100 area, 706-D building for barium separation and enrichment (RaLa), 706-C building for hot chemistry, 706-A building for chemistry, 200 area, 719-A biology section, and the general area. Results of air sampling and floor smears of the 706-D building are given in milliroentgens/hour (mr/hr). The reports also describe the surrounding air and off-gas releases associated with specific RaLa runs as well as incidents and decontamination and clean-up efforts. RaLa precipitation samples were monitored for tolerance levels of gamma and beta exposure. Monitoring information regarding the tank farm associated with the 706-D building is discussed.
