* Safe Entry has been determined by the DOE to be
10,000 years. At that point only some of the longer lasting radioactive
materials will continue to emit levels considered by some to be hazardous
(for periods sometimes in the range of 600,000+ year). Those materials
emit alpha rays, but are only dangerous or deadly if ingested, inhaled
or otherwise internally contact carbon based life forms.
