RE: Disposal of empty Kr-85 gas cylinders

["Baratta, Edmond J" <EBARATTA@ORA.FDA.GOV>]

At one time DOE took it back (10-15 years).  Let me know who handles it

now.?

Subject: Disposal of empty Kr-85 gas cylinders



 



Has anyone out there in Radsafe land had experience with disposal of gas

cylinders previously used for Kr-85 storage?  Is it sufficient to vent the

gas or it is necessary to purge the cylinders with nitrogen or some other

non-radioactive gas?  What level of residual gas might be expected?



 



Thanks for your help.
