  • Abstract
    The TL (thermoluminescence) stability of CaF2:Dy (TLD-200) and CaF2:Tm (TLD-300) has been investigated over a maximum of 900 hours of storage. The experiments were carried out in different climatic conditions of storage: storage in dry air at 30, 40 and 46°C; and storage in humid conditions at 30°C and 80% RH, 40°C and 80% RH, and 46°C and 80% RH. Among other findings, it is shown that CaF2:Tm is suitable as an environmental dosimeter material because of its insensitivity to the ambient conditions
