Re: Enriched tritium analysis

[Andrew Karam <karam.1@osu.edu>]

Standard Methods for the Examination of Water and Wastewater provides a
method for tritium analysis citing an accuracy of +/- 6% for activities of
200 pCi/ml and +/- 10% for activities of 1 pCi/ml.  The method is #7500-3H
and uses LSC.

LANL Health and Environmental Chemistry Manual provides a procedure for
Tritium in Environmental Matrices - Distillation and LS (method 210) that
claims an MDA of 2.5 pCi total activity or 500 pCi/L for a 5 ml sample.

The recent HASL Procedures Manual (available in PDF format at the EML WWW
page) provides two tritium analyses for water samples with an MDA of about
2.5 Bq/L (about 70 pCi/L).  These are procedures 3H-01-RC and 3H-02-RC.

Good luck!



The opinions expressed above are well-reasoned and insightful.  Needless to
say, they are not those of my employer. (with apologies to Michael Feldman)
