N2 - La-doping significantly improves the radiation hardness of PbWO4 against γ-ray irradiation. The induced absorption coefficient of La-doped samples is as small as 2 m-1 at 420 nm even at 108 rad (106 Gy). The radiation-induced phosphorescence is more than three orders of magnitude less in La-doped PbWO4 crystals than in undoped ones.
