1 DOSIMETER RADIATION FILM BADGE This is a non-functional demonstration of the film badges worn by Classified Radioactive Workers to measure the body dose of radiation received whilst working. In actual use, the different filters allow particular types of radiation to pass through to a radiation-sensitive film located behind the filters, and when processed the dose can be calculated. The badge has six filters, as below, but is supplied WITHOUT film. a. An open window which allows all incident radiation that can penetrate the film wrapping to interact with the film. b. A thin plastic film which attenuates beta radiation but passes all other radiations c. A thick plastic filter which passes all but the lowest energy photon radiation and absorbs all but the highest beta radiation. d. A dural filter which progressively absorbs photon radiation at energies below 65keV as well as beta radiation. e. A tin/lead filter of a thickness which allows an energy independent dose response of the film over the photon energy range 75keV to 2Mev. f. A cadmium lead filter where the capture of neutrons by cadmium produces gamma rays which blacken the film thus enabling assessment of exposure to neutrons. Cat No. Description Price Per RAD-800-100 Radiation Film Badge 12.76 ea. 2 LASCELLS CLOUD CHAMBER The Lascells cloud chamber is the perfect alternative to existing tricky and time consuming dry ice versions. The chamber is self-contained and thermoelectrically cooled. The chamber requires no dry ice or water; the only setup necessary is the addition of isopropyl alcohol and connection to a mains socket. The chamber contains an integrated power supply and illumination of the chamber is provided by a high intensity LED. Using the provided source, tracks should be visible within 10 minutes. Once running, the cloud chamber can be made to run for extended periods by adding more alcohol through the access provided in the lid. Cat No. Description Price Per RAD-595-100 Cloud Chamber 520.71 ea.
