New Test Method for Rapid Radiochemical Determination of Alpha-Emitting Uranium Isotopes in Water

1. Scope

The study of water, the promotion of knowledge thereof, and the standardization of terminology methods for:
* Sampling and analysis of water, waterborne materials, and wastes, water- formed deposits and fluvial sediments,
* Surface-water hydraulics and hydrologic measurements,
* The determination of the performance of materials or products used to modify water characteristics, and
* The determination of the corrosivity or deposit forming properties of water.
The term "water" includes, but is not limited to, surface waters (rivers, lakes, artificial impoundments, runoff, etc.), groundwaters and springwaters, wastewaters (mine drainage, landfill leachate, brines, waters resulting from atmospheric precipitation and condensation (with the exception of acid deposition), process waters, potable waters, glacial melt waters, steam, water for subsurface injection and water discharges including waterborne materials and water-formed deposits.
The work of the Committee will be coordinated with other ASTM Committees and other societies and organizations having mutual interests.

Rationale

This test method uses rapid radiochemical separation techniques for determining uranium in water samples and is suitable for use following a radiological or nuclear incident. This test method is considered a rapid method when compared to other classical methods for the determination of U-234, U-235, U-236, and U-238 in aqueous solutions. A batch of test samples plus quality control samples can be chemically processed in ~7.5 h. This test method can be combined with other Rapid Radiochemical Methods to accomplish sequential separation of a single test sample aliquant for isotopes of americium, plutonium, strontium, and thorium.

The title and scope are in draft form and are under development within this ASTM Committee.
