The absolute light yield of cerium doped lutetium oxyorthosilicate Lu[sub 2]SiO[sub 5]:Ce[sup 3+] (LSO:Ce) scintillation crystals is presented. From 60 keV to above 1 MeV the light output increases linearly with the gamma-ray energy and is about 67% of that of NaI(Tl[sup +]). However, a non-linear response is observed for X-ray energies between 5 and 60 keV. For comparison, the authors also studied the light yield of a Gd[sub 2]SiO[sub 5]:Ce[sup 3+] crystal and a CsI:Tl crystal as a function of excitation energy.
