Radioactive process liquid waste is generated during production of 99m Tc gel generator at Radiopharmaceutical Laboratory, BRIT, Vashi. The wastes were transferred to Waste Management Division, BARC, in carbuoys after assessment of activity content, to ensure that the activity limit set by the regulatory authority is complied with. A study was taken up for the optimization of decay time of effluent generated during the production of Tc-Gel generator. Study on the identification of the radio nuclides present in the liquid waste, to plan for disposal is discussed in this paper. Liquid waste aliquots were counted by different techniques and were followed for decay of activity over long duration. The analysis of the samples led to identify the long lived radio nuclides like 60 Co, 134 Cs and 65 Zn in liquid waste generated from 99m Tc gel generator production facility.
