DOE, LAS ‘VEGAS CONCERNING SOIL-IMP CALIBRATION
Richard O. Gilbert
May 24, 1978
This is a summary of my impressions of the April 26, 1978, meeting that
was called to consider two questions:
1.
2.
241
Am readings
(unbiased)
241
of surface soil relative to wet chemistry
Am concentrations?
Is the IMP giving sufficiently
accurate
If a problem exists , what is causing the problem?
Approximately
as chairman.
a dozen people were present.
Others in attendance
Paul Dunaway
(DOE) acted
(besides myself) were John Stewart and
Frank l’larkwell(DOE), Madaline Barnes and Jo Jane (Jodi) Giacomini
John Tipton
(DRI),
(EG&G), Al Doles (Eberline) and several others.
The question being discussed was whether IMP 241Am values are under241

Am concentrations in “surface” soil as determined
by wet chemistry

this could be the case, at least for some islands, apparently
