Comparison of Physical Properties of NaI(T), LSO, GSO, and BGO Scintillators
| Physical property | NaI(T) | LSO | GSO | BGO |
|---|---|---|---|---|
| Attenuation coefficient (cm−1) | 0.35 | 0.86 | 0.70 | 0.95 |
| Energy resolution at 662 keV (%) | 6.6* | 10 | 8.5 | 10.2 |
| Decay time (ns) | 230 | 40 | 60 | 300 |
↵* Energy resolution for signal after pulse clipping is 9%.
Decay time given for GSO corresponds to cerium concentration of 0.5 mol%. Energy resolution measurements are for single, Teflon (DuPont)-wrapped crystals on PMT. Data are from (9,10). Measurements for NaI(T) and GSO are consistent with published results.
