ABSTRACT:
A method and apparatus for determining radiation absorbed dose using optically stimulated luminescence (OSL) in dental enamel. The invention is based on the determination that OSL can be induced in dental enamel and can be used for determining absorbed radiation dose, for example during unmonitored x-rays, or accidental exposures to ionizing radiation. In particular, it has been discovered that there is a dose dependent OSL in dental enamel. The present invention makes possible a non-invasive, sensitive, reliable and portable method and apparatus for in vivo human radiation dosimetry.
