ASTM E181 2017 Standard Test Methods for Detector Calibration and Analysis of Radionuclides

American Society for Testing and Materials - 2017.- 21 p.
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. These methods are concerned only with specific radionuclide measurements. The chemical and physical properties of the radionuclides are beyond the scope of this standard. Among the measurement standards discussed are: the calibration and usage of germanium detectors, scintillation detector systems, scintillation detectors for simple and complex spectra, and counting methods such as beta particle counting, aluminum absorption curve, alpha particle counting, and liquid scintillation counting. For each of the methods, the scope, apparatus used, summary of methods, preparation of apparatus, calibration procedure, measurement of radionuclide, performance testing, sources of uncertainty, precautions and tests, and calculations are detailed.
These test 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.
These test methods are concerned only with specific radionuclide measurements. The chemical and physical properties of the radionuclides are not within the scope of this standard.
The measurement standards appear in the following order:
Spectroscopy Methods:
• Calibration and Usage of Germanium Detectors
• Calibration and Usage of Scintillation Detector Systems
• Calibration and Usage of Scintillation Detectors for Simple Spectra
• Calibration and Usage of Scintillation Detectors for Complex Spectra
Counting Methods:
• Beta Particle Counting
• Aluminum Absorption Curve
• Alpha Particle Counting
• Liquid Scintillation Counting.
Additional information on the set-up, calibration and quality control for radiometric detectors and measurements is given in Guide C1402 and Practice D7282.
