Abstract

A process for producing a lithium borate thermoluminescent and fluorescent substance containing lithium borate as its main component which comprises heat-treating a mixture of Li.sub.2 B.sub.4 O.sub.7 powder and an activator element compound at a temperature under and neighboring the melting point of Li.sub.2 B.sub.4 O.sub.7, to provide a highly sensitive fluorescent substance which has good adherence to the substrate of a dosimeter.
