With the advancement of neutron utilization technology, the development of thermoluminescent glass that enables easy and highly quantitative neutron detection is desired. In this study, two types of CaO–Al₂O₃–B₂O₃–SnO₂ glass (¹⁰B-enriched and ¹¹B-enriched glasses) were fabricated, and their thermoluminescent properties after X-ray and thermal neutron irradiation were investigated. The results showed no difference in thermoluminescent properties between the glasses for X-ray irradiation. However, for neutron irradiation, the ¹⁰B glass exhibited five times the luminescence intensity, indicating the neutron reactivity of the ¹⁰B glass.
