BETA-SENSITIVE FIBER OPTIC DOSIMETRY SYSTEM Russian patent published in 2024 - IPC G01T1/20 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement of ionizing radiation using scintillation detectors and can be used in designing dosimetry systems and complexes. Beta-sensitive fiber-optic dosimetry system includes a scintillator integrating a sphere with a fiber output, transport optical fiber, photon counter and personal computer, wherein photons arising in the scintillator during interaction with electrons from a beta ionizing radiation source placed inside the integrating sphere are scattered by the sphere material and fall on its output port, connected by means of transport optical fiber with photon counter, signal from which by means of connecting cable is transmitted to personal computer, which is also connected to a vacuum sensor located at the inlet of the vacuum pump by means of a vacuum pipeline connected to the inner volume of the integrating sphere.

EFFECT: high accuracy of measuring output of beta-electrons from a metal source of arbitrary shape into angle of 4pi.
