1.1 This guide provides concepts, terminology, notation, and recommendations for the evaluation and expression of the uncertainty of radiochemical measurements of water and other environmental media in testing laboratories. It applies to measurements of radionuclide activities of water samples, including gross activities, regardless of whether they involve chemical preparation of the samples. 1.2 This guide does not provide a complete tutorial on measurement uncertainty. 1.3 The system of units for this guide is not specified. Dimensional quantities in the guide are presented only as illustrations of calculation methods. The examples are not binding on products or test methods treated.

This standard will help workers in the field of radiochemistry who need to perform uncertainty analyses for their measurements or understand uncertainty analyses done by others. It should also be a reference for developers of commercial software used in radiochemical measurements.
