This Cobalt 60 program is part of the Richland five year 02 R&D program. Topics discussed in this summary include incentives, scope and objectives, progress during report period, budget period plans, and an evaluation of progress against plans and objectives. Progress has reasonably paralleled expected results in that megacurie quantities of Co-60 have been secured with activities of 20--60 curies per gram by January 1966 and 100 curies per gram by July 1967.
