Re: Charcoal Impregnated HEPA Filters

     Since I don't actually know what is going on here I don't know if the 
     following is a worthwhile suggestion or not, but I think that, at 
     least temporarily, you can get away with using Personal Protective 
     Equipment such as Combination Organic Vapor-HEPA cartridges and 
     personal respirators.  
     
     You have got an interesting problem here.  I really do not know of any 
     manufacturers of industrial equipment who have got the combination 
     filters you are looking for.  But I would be interested in hearing of 
     any manufacturer/equipment out there.  Good Luck with your search.

Dear Radsafers,

We are currently looking for charccoal loaded HEPA filters for industrial
use.  These filters are requested for a certain work to be undertaken in a
very near future, and as it stands now, the only manufacturer we were able
to locate is in Switzerland. Their delivery times are quite long.

As a matter of fact, I also wanted to ask for an info from (but not only)
nuclear power plants staff about some experience with antimony family in the
air (specificaly, Sb-124 and/or 125) and their "alleged" passing through the
normal HEPA Filters.  Is there anybody to contact who could give us a thought.  

Thank you very much in advance.
