Brief Method Summary
|
Americium, plutonium and uranium are separated by Eichrom resins prior to measurements by alpha spectrometry. Tracers are used to monitor chemical recoveries and to correct the results to improve precision and accuracy. This is a rapid, reliable method for the measurement of actinides in water samples that is more cost-effective and efficient than traditional ion exchange, solvent extraction and precipitation techniques. The method is adapted from Eichrom Industries, Inc., Procedure ACW03, Rev. 1.5. |

Scope and Application
|
This procedure describes a method for the separation and measurement of americium, plutonium and uranium in water. |
|
Applicable Concentration Range
|
None given. |
|
Interferences
|
(A) Unresolvable alpha energies - Actinides with unresolvable alpha energies such as Am-241 and Pu-238 or Np-237 and U-234 must be chemically separated to enable measurement. This method effectively separates these isotopes. |
