We fabricated neutron detection glasses, Tb 3+ -doped CaOAl 2 O 3 B 2 O 3 glasses, including 10 B-enriched ( 10 B glass) and 11 B-enriched ( 11 B glass) glasses. The glasses were irradiated with X-rays, heavy particles, or neutrons and their thermoluminescence (TL) properties were investigated. The TL properties after X-ray or heavy particle irradiation were the same for the 10 B and 11 B glasses. Meanwhile, after neutron irradiation, the TL properties of the 10 B and 11 B glasses were
