適用范圍：This International Standard applies to gamma-ray spectra collected with hyperpure germanium detectors (HPGe) for use in gamma-ray spectrometry, especially for low-background detectors and measurements. This standard defines terms used to describe the background and the background spectrum itself. This standard does not present methods that describe how to reduce the background. The object of this standard is to provide a uniform method for describing and characterizing the background in a spectrum from an HPGe detector. Definitions and methods are applied to define values for an HPGe detector that is considered to be used for low-background measurements. This approach provides both manufacturers and end users with a way to specify the low-background performance of the detector and allows the comparison of detectors used for these kinds of measurements. The background and peak values determined by the procedures in this standard will provide the user with information regarding the expected background performance of the detector, in particular to allow for the comparison of several different detectors.
