  • Radiation dosimeter for the detection and/or dosimetry of radiation, particularly UV radiation
    Patent number: 5696381
    Abstract: The radiation dosimeter for the detection/and or dosimetry of radiation, particularly UV radiation, is provided with a housing comprising an opening. A sensor device sensitive to the radiation of interest is arranged below the diffuser cover layer (10). The diffuser cover layer (10) covers an opening and is transmissive at least to the radiation of interest.

  • Biological detection of radiation
    Patent number: 5371004
    Abstract: The present invention relates to a method and a device for the biological detection of radiation by microorganisms in form of a microorganism coating provided on a sheet substrate, which microorganism coating is exposed, optionally after calibration by exposure to a defined radiation dose, to the radiation to be detected. The principle of evaluating the biologically weighted quantification of the radiation dose consists of photometrically determining the decrease in response to the radiation dose of the amount of synthetically formed products upon selectively staining the biosynthesis products.
