True Coincidence Summing Correction for Cylindrical Volume Samples in γ-ray Spectrometry

True Coincidence Summing Corrections

Measuring γ–ray dose of terrestrial samples using β-γ Spectrometry

Background: The existence of some radionuclides in soil and some building materials produce a β-γ radiation field, which in some regions the exposure of these radionuclides to human is high. Materials and Methods: The air-absorbed dose, indoor and outdoor annual effective dose of soil and some building material samples (ceramic, granite, gypsum, etc.). The samples were collected from 3...

Performance of the True Coincidence Correction Method in GammaVision

Some nuclides emit multiple gamma rays or X-rays when they decay to the ground state. If these gamma rays and X-rays are emitted essentially at the same time, it is possible that multiple photons will be detected at the same time in the detector and appear as one full-energy peak in the spectrum. This is known as “Cascade” or “True Coincidence” summing. The most common example of this is Co, wh...
