NAC459.827. Waste containing long-lived radionuclides.

If the radioactive waste contains only the long-lived radionuclides listed in Table 1, classification must be determined as follows:

TABLE 1

Radionuclide	Concentration in curies/cubic meter
C-14	8
C-14 in activated metal	80
Ni-59 in activated metal	220
Nb-94 in activated metal	0.2
Tc-99	3
I-129	0.08
Alpha emitting transuranic radionuclides with half-life greater than 5 years	100*
Pu-241	3,500*
Cm-242	20,000*
* Units are nanocuries per gram

     1. If the concentration does not exceed 0.1 times the value in Table 1, the waste is Class A;

     2. If the concentration exceeds 0.1 times the value in Table 1, the waste is Class C; and

     3. If the concentration exceeds the value in Table 1, the waste is not acceptable for burial at any state-owned disposal area.
