Abstract: A novel apparatus and fully automatic, computer implemented method for making radiation dose measurements using composite glow curve data obtained with a thermoluminescent dosimetry reader wherein such composite glow curve data is composed of the superposition of plural overlapping glow peaks plus instrumental and dosimeter background. The background component of the composite glow curve is subtracted out by using an automatic peak search technique followed by individual chip background subtraction based upon the extrapolation of the background curve under the glow curve by fitting on both sides of the curve outside the region of the peaks. Following background subtraction and automatic identification of low temperature signal limits, the leading edges of higher temperature dosimetric peaks are extrapolated to lower temperatures to subtract from the glow curve a lower temperature dosimetric peak without affecting the higher temperature dosimetric peaks. Computerized deconvolution also is effected automatically by computing initial parameters directly from the glow curve shape and with reduced processing time by applying analytical differentiation to a model equation.

The altered information is used to provide a measure of both the radiation dose and energy. In a preferred embodiment, the optical memory device is a 3-D ORAM comprising a volume of a transparent polymer doped with a light sensitive chemical and, in particular, spirobenzopyran. Also disclosed are a spectrometer for monitoring neutron and other types of radiation, an electronic dosimeter for providing real time monitoring of radiation exposure, and associated methodologies, all based on use of an optical memory element.

Abstract: The method and system interpretation for determining dose equivalents of a multi-element thermoluminescent dosimeter in mixed photon-beta and photon-neutron fields is described. The four TL Elements are covered by nearly tissue equivalent filters including only one metal filter which is used to provide low energy photon discrimination. In a mixed field, deep and shallow dose equivalents and the identity of the field's components are derived from the dosimeter's response in pure fields.
