aSpecific
activity limit depends on waste form indices; values shown are for nonfuel reactor components and
high-activity industrial waste.
bThe 10 CFR 61 specific activity limits for Sr-90, Tc-99, I-129, and Cs-137 are multiplied by a factor of ten
because they are assumed to be contained in activated metal.
cTMSA = Theoretical Maximum Specific Activity: ky = 1000 years; My = 1,000,000 years; Gy = 10 9 years.
g
Other values: d10 CFR 61.55, 61.56; ePonti 1986; fManinger 1985;
Kennedy 1983.
