2. Storage for Decay

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.
