Coincidence gamma-ray spectrometry [PDF]
, 2017 Gamma-ray spectrometry with high-purity germanium (HPGe) detectors is often the technique of choice in an environmental radioactivity laboratory. When measuring environmental samples associated activities are usually low so an important parameter that describes the performance of the spectrometer for a nuclide of interest is the minimum detectable ...

Scattering of gamma radiation by air in the ambient environment using gamma ray spectrometry
Kuwait Journal of Science, 2023 The intensity of gamma radiation reduces as it traverses through matter. The gamma radiation from earth’s surface is attenuated by non-radioactive burden between the ground and the detector.
