DOE-HDBK-1106-97
c. Segregate: Segregate clean materials from radioactive materials. Do not
dispose of clean materials in radioactive waste containers.
d. Good housekeeping: Contamination control measures such as covering
benches, etc. generate waste. On the other hand, decontamination generates
a great deal of waste. Good housekeeping, following procedures,
minimizing bench areas, and secondary containment can reduce the amount
of coverings required.
2.
Storage for Decay
a. Storage: Some radionuclides have a short half-life and can be stored, with
appropriate DOE approval, for decay. Normal storage times are 10 half-
lives. The waste must be surveyed prior to disposal to ensure it is below
disposal criteria.
b. Substitution: Substitute shorter-lived for longer-lived radionuclides, if
possible.
3.
Disposal via Sanitary Sewer
Disposal of small quantities via sanitary sewer is available to some facilities.
Add facility-specific information.
4.
Disposal of specific waste per 10 CFR 20.2005
In accordance with Part 20.2005, NRC licensees may dispose of the following
as if it were not radioactive:
a. Liquid scintillation counting media: Liquid scintillation counting media
containing 0.05 microcuries or less per gram of medium of H-3 or C-14.
b. Animal carcasses: Animal carcasses containing 0.05 microcuries or less per
gram of animal tissue (averaged over the weight of the entire animal) of H-
3 or C-14.
