    Withdrawn Rationale:

    This practice describes the use of an ion exchange technique to separate plutonium from solutions containing low concentrations of americium prior to measurement of the 241Am by gamma counting.

    Formerly under the jurisdiction of Committee C26 on Nuclear Fuel Cycle, this practice was withdrawn in July 2020. This standard is being withdrawn without replacement due to its limited use by industry.

    1. Scope

    1.1 This practice describes the use of an ion exchange technique to separate plutonium from solutions containing low concentrations  of americium  prior  to measurement of the 241Am by gamma counting.

    1.2 This practice covers the removal of plutonium, but not all the other radioactive isotopes that may interfere in the determination of 241Am.

    1.3 This practice can be used when 241Am is to be determined in samples in which the plutonium is in the form of metal, oxide, or other solid provided that the solid is appropriately sampled and dissolved (See Test Methods C758, C759, and C1168).

    1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
