Radium 226 by gamma spec analysis

[Erik Nielsen <enielsen@antechltd.net>]

I am trying to find a reference citation for the rather common analytical technique of canning a soil sample, waiting 21 days and counting by gamma spectroscopy for the Bi-214 and Pb-214 daughters of the Rn-222 at equilibrium.

A regulator needs some sort of government citation of this method prior to approval.

I know there was a citation in USGS publications where this method was used to analyze mill tailings for Ra-226.

Of course any online references would be preferred but can use any ideas that anyone has.
