Average Commercial Low-Level Radioactive Waste

Another example involves classification of average commercial low-level radioactive waste. The total activities of the dominant radionuclides in the waste, as obtained from data for all Class-A, -B and -C low-level waste emplaced in near-surface disposal facilities in the United States in 1990, are given in Table 7.4 (DOE, 1993b). These estimates do not account for decay that would occur during the 100 y institutional control period. That is, inadvertent intrusion is assumed to occur at the time of facility closure. Radionuclide concentrations are based on the estimated volume of waste and an
