Abstract:
An optic module verification device for normalizing between X photon counters, including a verification tray with X verification wells and a modular photon emitter in each verification well. Each photon emitter includes a spring, a Beta source disk, a scintillator disk adjacent the Beta source disk, and a neutral density filter over the scintillator disk, all of which are encapsulated in a cylindrical chamber with the filter adjacent an opening on one end of the chamber and the spring biasing the Beta source disk and the scintillator disk toward the opening. The device is periodically used for normalization, and may be updated when emitted photons fall below a desired level by replacing the scintillator disk and then determining a new normalized reference values for each photon emitter.
Abstract:
A radioactive light source consists of a vacuum tight envelope filled with a mixture of a radioactive gas such as tritium with one or more other gases which luminesce when excited by the emission from the radioactive gas without the aid or requirement of any externally applied energy source, such as electrical power. This luminescence may be viewed through the wall of the chamber which may be transparent. Alternatively, all or a part of the luminescence may be converted to a different region of the spectrum by a suitable phosphor layer coated on the wall of the envelope.
Abstract:
A module (50) comprising: one or more vials containing tritium; one or more tritium covers (52); and an open space within the one or more tritium covers, wherein the one or more vials containing tritium (54) are located within the open space of the one or more tritium covers so that the one or more tritium covers protect the one or more vials containing tritium, and wherein the one or more tritium covers are made from a material that exhibits sufficient strength so that the module protects the one or more vials containing tritium from damage when dropped from a distance of 1 m or more.

Abstract:
A dielectric barrier discharge, DBD, lamp device comprises a toroid shaped discharge chamber ( 10 ) having a discharge chamber wall ( 12 ). The discharge chamber wall comprises a tubular inner wall section ( 14 ), a tubular outer wall section ( 16 ), and two ring-shaped end wall sections ( 18, 20 ). Each of the end wall sections extend between an end of the outer wall section and an end of the inner wall section. A high voltage electrode ( 22 ) is provided at an outer surface of the outer wall section of the discharge chamber wall. A low voltage electrode comprises an electrically conducting fluid surrounded by the inner wall section of the discharge chamber wall. The DBD lamp device may be part of an optical fluid treatment device.
