UV LUMINESCENCE DOSIMETRY

摘要

FIELD: physics.SUBSTANCE: invention relates to radiation measurements and concerns a luminescent dosimeter of UV radiation. Dosimeter includes a sensitive element, transmitting optical fibre, movable cassette with optical filters and a photodetector. Sensitive element is made in form of a fibre made from potassium-alumino-borate glass with molecular clusters of chloride and copper oxide, and is optically connected to a photodetector via transmitting optical fibre and a movable cassette with optical filters. Optical filters have bandwidth in visible spectrum with spectral width of 20-30 nm.EFFECT: technical result consists in expansion of spectral range of measurements and high stability of dosimeter to external effects.1 cl, 4 dwg
