Series Description: This report is a history of RaLa operations from 1944 to 1949. During this period, ORNL sent 31 shipments of RaLa to Los Alamos. The report discusses contamination resulting from RaLa operations, particularly iodine-131, giving the total number of curies produced during each dissolution run. The history provides background information on the development of the barium-lanthanum separation process and the construction of buildings where that process took place. It also assesses the current state of RaLa production and prognosis for the future. An extensive bibliography lists the literature produced at ORNL concerning RaLa and appendixes outline the operations of buildings 706-C and 706-D.
