URI: valuesets:WasteHalfLifeCategoryEnum

Permissible Values

Value Title Meaning Description Containment Period Decay Significance Decay Strategy Examples Half Life Range Typical Examples
VERY_SHORT_LIVED Very Short-Lived Radionuclides with very short half-lives storage for decay seconds to days medical isotopes, some activation products
SHORT_LIVED Short-Lived Radionuclides with short half-lives hundreds of years significant over containment period <30 years
LONG_LIVED Long-Lived Radionuclides with long half-lives thousands to millions of years minimal over human timescales actinides, some fission products >30 years
