We have always followed a policy to NOT autoclave I-125 contaminated 
waste.  I have, however seen products and devices designed to "filter" or 
"trap" the volatile radioiodine as heated air escapes the bag during 
autoclaving. We have never used such devices, so I am not sure what 
their effectiveness is.

Our preferred method is to inactivate the biowaste chemically.  
Another note - bleach is not appropriate for  chemical inactivation 
as I believe it can also release some radioiodine.  Use another 
commercially available disinfectant such as Wescodyne, etc.
