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.
