Abstract

This invention discloses an oriented triplex dosimetry sensor (1) composed of three layers, namely, the photo-sensor made of large-resistivity semiconductor bulk-plate (4) pasted to the intermediate alanine layer (3), where radiation induced free radicals are detected by EPR technique, which is agglutinated further to a GaN scintillator (2) (Fig. 1), wherein (2), (3) and (4) layers of the triplex sensor are sequentially scanned by the spectrophotometer, the EPR scanner and the microwave detection system, where particle discrimination and fluence measurements are performed by correlating signals of the scintillator spectrum structure, the EPR signal amplitude and the photoconductivity decay lifetime, while depth variations of the accumulated dose serve for estimation of the radiation streamline. These small dimension triplex sensors can be composed into 1D cells comprising several face-to-face and in line deployed triplex sensors, while triplex sensor structures oriented in perpendicular directions are applicable for estimation of location of the radiation source.
