Gamma-rays can transfer energy to the detector system through Compton scattering in the walls or fill gas. Most materials emit 10+ times as many γ-rays as neutrons, so γ-ray sensitivity is an important criterion in instrument selection.
There are four factors to consider when choosing an instrument:
Below we can see the n and γ-ray interaction probabilities for typical detectors:
The following chart shows n and γ-ray deposition in typical detectors:
