THERMOLUMINESCIENCE OF SAPPHIRE

摘要

A novel technique and dosimetric material is disclosed for the detection and measurement of ultraviolet radiation. Nominally pure sapphire containing trace impurities such as manganese, chromium, iron and titanium is ground into a powder form of approximately 200 mesh particle size. The sapphire is then excited with incident ultraviolet radiation and subsequently heated whereby the sapphire thermoluminesces. The intensity of the resulting luminescence is a measure of the ultraviolet radiation dosage to which the sapphire has been exposed.
