Re: Kr-85

     Joe,
     
     When I add up all the natural abundances of all the grey boxes on the 
     Kr part of the chart of nuclides, I get 100%.  Kr-85 has a short half 
     life to stay around for any period of time (~4 1/2 hrs).  I could not 
     imagine Kr-85 being a rad problem, unless it was being produced by 
     nuclear methods and not cryogenic-from the atmosphere methods.

Radsafers:
Reading a report from a company that produces specialty gases (e.g., Kr from 
the atmosphere via a cryogenic method), they are convinced that they have a 
rad problem with Kr-85.  I do not know the basis for their concern. Has 
anyone ever heard of a similar situation.
I would appreciate any information you have.
