Method Name:
Americium and Plutonium by Ion Exchange and Alpha Spectrometry . Official Name: Americium in QAP Water and Air Filters - Eichrom's TRU Resin

Description:
Water and air filters are equilibrated with americium and processed through plutonium separation steps using ion exchange. The eluate from the ion exchange column is evaporated, redissolved, and loaded onto a TRU Resin extraction column. The americium (and curium, if present) is separated and purified on the column and finally stripped with dilute nitric acid. Microprecipitation of the chloride salts is followed by analysis by alpha spectrometry using Procedure A-01-R.

Scope:
Separation and analysis of spiked water and air filter samples that contain americium but not lanthanides.

Citation:
DOE EML Procedures Manual HASL-300, Volume 1, 28th Ed.(1997)

Interferences:
Lanthanides will significantly reduce the resolution of the alpha-spectrograph.

QC Requirements:
Americium-243 tracer and other appropriate tracers must be added prior to separation and analysis.

Media:
VARIOUS

Subcategory:
Radiochemical

Sample Prep:
See Procedure Pu-10-RC for water samples.

Precision:
-

Detection:
Performance data in the method is for americium; curium is mentioned also in this method but no performance data is provided for curium.

Revision Number:
