? releasing freezers as non rad waste

["John Zummo" <zummo@gene.com>]

If someone had a freezer which had biological waste in it for a few
years, containing isotopes like Co-57 and Sn-113, is there a way to
release it (the freezer) as non-radioactive waste?  Has anyone tried to
use liners as well as double bags to try to limit contamination spread? 
Is the migration into the frost previously discussed limited to H-3?

Thanks for any info.

Regards,

John
