Standard Guide for Analysis of Calibration Data for Nuclear Instruments

Importancia y uso:

5.1 The mathematical and statistical techniques described in this guide support implementation of the calibration requirements of Practice D7282 and the guidance for uncertainty analysis given in Guide D8293. The guidance is intended for use either by qualified specialists at a radioanalytical laboratory or by developers of software for calibration of nuclear instruments.

5.2 Applications for single-point calibrations might include:

5.2.1 Alpha-particle spectrometry,

5.2.2 Gas proportional counters used for thin sources with negligible attenuation, and

5.2.3 Gamma-ray spectrometers used for single nuclides.

5.3 Applications for calibration curves determined by LLS might include:

5.3.1 Mass attenuation curves for gas proportional counters (polynomial), and

5.3.2 Quench calibration curves for liquid scintillation counters (polynomial).

5.4 Applications for calibration curves determined by NLLS might include:

5.4.1 Gamma-ray spectrometry across a range of gamma-ray energies,

5.4.2 Mass attenuation curves for gas proportional counters, and

5.4.3 Quench calibration curves for liquid scintillation counters.

5.5 Although this guide focuses on efficiency calibrations for nuclear instruments, the same general principles and paradigms should apply to other types of calibrations and to other instruments, as long as there are valid uncertainty models for the calibration data.
