EQUIPMENT LOCATING POSITIONS OF RADIOACTIVE SOURCE IN REAL TIME Russian patent published in 1999 - IPC

FIELD: remote radiation monitoring of radioactive objects in real time in premises, low-activity objects included. SUBSTANCE: images of sources in optical and own radiation are recorded in proposed equipment with the use of one and same position-sensitive detector -CCD matrix. Each cell of it is elementary detector with high signal-to-noise ratio which makes it possible to carry out counting mode of measurement of position of radioactive sources in real time. Energy of quantum ( particle ) from source is converted in element of CCD matrix to pulse directly carrying information on position of radiation source. Pulses from elements of zones of images of radiation sources can be summed as well as full frames of image from CCD matrix to ensure necessary statistical accuracy of recording of radiation of radioactive sources of low activity. EFFECT: increased sensitivity and simplified design of equipment. 2 dwg
