METHOD OF DETERMINING IONISING RADIATION CHARACTERISTICS AND APPARATUS THEREFOR

摘要

FIELD: physics.;SUBSTANCE: group of inventions relates to detection of ionising radiation using scintillation detectors, and specifically to detection of the form of X-ray and electronic radiation pulses, particularly fibre-optic dosimetry. The method includes converting ionising radiation into a light signal in a scintillator, transmitting the signal via a fibre-optic channel and splitting the signal, followed by picking up Cherenkov radiation from one signal and scintillation radiation with a fraction of Cherenkov radiation from the other, by passing each signal through its own narrow-band optical filter, differing from each other by the spectral range, converting the signals into electrical signals which are taken into account when processing to determine characteristics of the ionising radiation, wherein the electrical signals are processed using an analogue subtractor, where one signal is subtracted from the other followed by determining: the shape of the obtained signal, dose per pulse, duration, maximum power without the effect of Cherenkov radiation, wherein at any section of transmission of one of the signals before or after conversion thereof into an electrical signal, said signal is delayed in order to synchronise the arrival of both converted electrical signals at the analogue subtractor.;EFFECT: broader functional capabilities.;5 cl, 1 dwg
