METHOD AND DEVICE FOR MEASUREMENT OF LARGE FLUENCES AND DOSES OF HIGH ENERGY IRRADIATIONS

摘要

The present invention provides method for measuring large doses of irradiation, and is addressed to simultaneous detection and dosimetry of gamma rays and high energy hadrons, which is implemented by exposing of the tandem dosimeters to unknown radiation, by receiving data at the first reader - electronic paramagnetic resonance spectrometer, from at least one dosimeter, that is set to detect gamma rays, and additionally, at the second reader - non-equilibrium carrier recombination lifetime meter, from at least one dosimeter, that is set to detect hadron irradiation, using contactless means of microwave probed photoconductivity transients in monocrystalline silicon, coated with properly passivated surfaces, under excitation of a pulsed IR laser light, linking of the obtained data in both dosimeters, integrated into a single tandem dosimeter, and evaluation of the dose, the spatial dose distribution of gamma rays and hadron irradiation using the relevant models and analysis software.
