RE: Decay-In-Storage

["Jean-Francois, Stephane" <stephane_jeanfrancois@merck.com>]

Wow,now I undertsand your point. You see,  I was only presuming that you had
a certain licence condition regarding rad waste disposal. But in Canada, we
don't have such precise rule (10 HL + monitoring). We have to meet certain
maximum quantities, period.

So now I understand the basis of your initial query !!!  I can't find any
answers, as what Sandy reported previouly is true: 10 HL , 1000 HL or 2 HL,
it is the final result that count (do you get it ?). But if you have the
facility to decay in storage, I don't see why you would not wait. It is a
case of :" I would rather know where the stuff is decaying then the
opposite..."

          If what Sandy say's is true than why are the regulatory folks 
          requiring 10 half-lives AND non-detectable?  It's a license 
          condition I must adhere to and document.
