ABSTRACT:
A personal electronic ultraviolet dosimeter for measuring exposure to short wavelength electromagnetic radiation. The dosimeter is for personal use to determine cumulative exposure to radiation. Exposure dosage is determined through the photodissolution of a metal-containing film into a chalcogenide glass upon illumination or exposure. This process of photodissolution of a metal-containing film into a chalcogenide glass changes the electrical resistance of the metal-containing film. To determine exposure, the increase in the electrical resistance of the exposed metal-containing film may be measured and in turn related to dosage.
