Series Description: This report summarizes the production of radioisotopes in buildings 706-D and 105 in December 1946. Building 706-D handled separated materials and 105 unseparated materials. The isotopes separated in 706-D included iodine-131, carbon-14, phosphorous-32, ruthenium-103-106, praseodymium-143, sulfur-35, and calcium-45. The report provides the total number of shipments per month for each radioisotope, and the weight of each shipment in grams. Building 105 handled materials that were unseparated, such as tellurium for iodine-131. Methods used in both buildings to safeguard against contamination are described.
