RADIOLUMINESCENT UV-RANGE IRRADIATOR Russian patent published in 2006 - IPC G01N21/62 G21H3/02 

FIELD: measurement technology.

SUBSTANCE: radio luminescent irradiator has exit window made in form of polished disc disposed in the same case with crystal phosphor and β-radioactive matter which excites radio luminescence. As crystal phosphor and exit window, the radiator has crystal on base of SrF₂:Er³⁺, which has the following content (in mass percent): SrF₂ - 99,01-99,9% and ErF₃. Radiator is capable of radiating at super-short wavelength of 146,5 nm.

EFFECT: improved light output; reduced weight of radiator; ability of radiate at super-short radiation wavelength.
