Gamma-ray photons from
the source will undergo interactions with the surroundings of the detector, i.e. the:
- the shielding;
- the cryostat;
- the detector cap; and
- the source mount etc.,
These unavoidable interactions can influence the shape of the spectrum recorded by the detector.
Use this animation to illustrate the different sources of secondary
radiation from the lead shielding surrounding the detector.
