Doplňujúce informácie
| Significance and Use | ||||||||||||
|
Alpha-particle spectrometry can either be used as a quantitative counting technique or as a qualitative method for informing the analyst of the purity of a given sample. The method may be used for evaporated alpha-particle sources, but the quality of the spectra obtained will be limited by the absorbing material on the planchet and the surface finish of the planchet. |

| 1. Scope | ||||||||||||
|
1.1 This practice covers the processes that are required to obtain well-resolved alpha-particle spectra from water samples and discusses associated problems. This practice is generally combined with specific chemical separations, mounting techniques, and counting instrumentation, as referenced. 1.2 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. |
