Two nondestructive assay systems, the MEGAS and the Pancake Counter, for the measurement of transuranic contaminated solid wastes at 10-nCi/g activity levels, have been developed. These are Nal-based detection systems to be used specifically for low-density solid transuranic wastes. They are of value in effective implementation of new federal regulations pertaining to transuranic waste management in that they supplement the usual administrative decision making in waste handling.
