METHOD AND APPARATUS TO DISCRIMINATE OUT INTERFERENCE IN RADIATION DOSAGE MEASUREMENTS

摘要

A method and apparatus to mitigate interference, also known as the stem effect, from Cerenkov radiation and fluorescence photons generated in optical fiber radiation detectors, provide for real-time ionizing radiation measurement. The fiber optic detector has a radioluminescent scintillator at its tip. Data collection from the fiber optic dosimeter is gated so that photons from the scintillator radioluminescence are collected after Cerenkov radiation and fiber fluorescence photons disappear. Data collection is striggered by detecting the presence of a scattered radiation field when the pulsed radiation beam is on.
