RE: Kr-85

["Mcelrath Susan S." <MCELRATHS@rscpo1.wilm.ge.com>]

Our Kr gas supplier sent a notice that some cylinders would require 
radioactive labeling due to the inherent Kr-85 content in a cylinder of 
"regular" Kr extracted from the atmosphere.  It's over the threshold that 
requires labeling per DOT regulations.  This particular gas vendor isn't 
worried about radiation exposure (and rightfully so); just complying with 
DOT.

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.
