What is the light output of GSO scintillators?

GSO (Gadolinium Oxyorthosilicate) scintillators are known for their effective scintillation properties, particularly in the context of PET scanning. The light output of GSO scintillators is typically measured in terms of photons produced per unit of energy deposited, which is often expressed in terms of the number of photons produced per MeV (million electronvolts) of gamma energy absorbed.

The correct answer indicates that the light output of GSO scintillators is around 30 photons/MeV. This value reflects the efficiency and effectiveness of GSO as a scintillator in capturing and converting gamma radiation to visible light, which is then detected by photomultiplier tubes or other detection systems used in PET imaging.

This level of light output makes GSO a suitable choice for applications in medical imaging, as it provides a balance between light yield and performance. Understanding the specific light output is crucial for optimizing detector design and improving the overall image quality in PET scans.
