sure they are separating out the potassium (K-40)?  I don't recall seeing
an answer to that question and it could make all the difference.

I have written a detailed answer and I have extensively commented the
analytical approach which had been posted on RADSAFE.

All methods to determine Sr-90 separate it chemically by precipitation,
adsorption, extraction etc. The methods used separate it also from any K-40
which might be present. The method as such is o.k. The thoughts behind - as
again and again distributed by Norman, though already extensively discussed
- are the problems. The wrong statements he makes, which have been
identified to be wrong over and over again, these are the problems. The
method of people like Norman, to repeat again and again the same nonsense,
until some people believe it - this is a problem. But now radiochemical
methods!
