ANGLEAngle is long existing and well known software for gamma-efficiency calculations for semiconductor and scintillation detectors. Angle allows for accurate determination of the activities of gamma-spectroscopic samples for which no “replicate” standard exists, in terms of geometry and matrix. Semi-empirical “efficiency transfer” (ET) approach is used, based on the effective solid angle (Ω) calculations.


Angle 4, the actual version, is a result of 30 years of development, practical experience in numerous gamma-spectrometry laboratories worldwide and constructive users’ feedback.
