ASTM E181-98

1.1 These methods cover general procedures for the calibration of radiation detectors and the analysis of radionuclides. For each individual radionuclide, one or more of these methods may apply.

1.2 These methods are concerned only with specific radionuclide measurements. The chemical and physical properties of the radionuclides are not within the scope of this standard.

1.3 The measurement standards appear in the following order:

Sections Spectroscopy Methods: Calibration and Usage of Germanium Detectors 3 to 12 Calibration and Usage of Scintillation Detector Systems: 13 to 20 Calibration and Usage of Scintillation Detectors for 16 Simple Spectra Calibration and Usage of Scintillation Detectors for 17 Complex Spectra Counting Methods: Beta Particle Counting 25 to 26 Aluminum Absorption Curve 27 to 31 Alpha Particle Counting 32 to 39 Liquid Scintillation Counting 40 to 48

1.4 This standard does not purport to address all of the safety problems, 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.
