What is the density of GSO scintillators?

GSO, or Gadolinium Oxysulphide, is a commonly used scintillator material in PET imaging due to its favorable properties like high stopping power for gamma rays and good light output. The density of GSO scintillators is approximately 6.71 g/cm³. This density is significant because it affects the material's ability to absorb radiation and its overall performance in detecting gamma rays emitted during PET scans. Higher density materials generally offer better stopping power, but they also come with other considerations such as weight and radiation attenuation properties.

Thus, understanding the density of GSO is crucial for ensuring effective design and application in PET systems, where the balance of detection efficiency and material characteristics plays a vital role in imaging performance.
