Instruments for radiation detection, determination of radioactive sources & measuring their intensities. 

RT-20

  • The smallest representative of hand held scintillators.

  • Suitable for rapid localization and tracking of radiation sources.

  • Easy to operate and Low power consumption. 

Properties

  • Clear and easy-to-read display

  • Audible indication of changes in radiation levels make RT-20 suitable for routine work when locating sources of radiation.

  • Unit is also available with an extension.

  • Low weight so easily portable even in rugged conditions.

  • Dimensions of the device have been minimized, but not at the expense of sensitivity

  • ​Housing made of aluminium alloy.

  • Powered by four AA cells, Alkaline and rechargeable cells are also acceptable and charge controller is located inside unit.

  • Housing enclosure protected against scratches and bumps with a plastic finish on the outside and foam lining inside.

  • NaI / Tl crystal of 1.18 " diameter & 1.18" length and Gamma-ray energy range from 30 keV ensures sufficient sensitivity of unit for radiation sources contained in massive shielding or transport containers.

Use

  • Designed primarily for work in areas where probability occurrence of significant radiation sources                                             is high and difficult access.

  • Metal scrap and other waste.

RT-30

  • Handheld multi-purpose gamma ray spectrometer with integrated dose meter and neutron identification.

  • High sensitivity, long operating time and high durability in field conditions.

  • Quick scanning for radioactive materials and reliable identification of radioisotopes.

  • Protection of personnel against the effects of ionizing radiation.

Properties

  • Detects radiation sources, measuring dose rate and identifying neutrons.

  • Low weight, high mechanical resistance and water resistant

  • Monitoring and analysis results are displayed on a graphic display in a well-arranged manner.

  • All acquired data is stored in the unit's memory and can be exported to other devices via USB or Bluetooth. 

Use

  • Industrial applications, personal protection, tracking illegal movement of radioactive sources and searching for lost radiation.

  • Built on a large volume NaI / Tl scintillation detector with a 2" base diameter and 2" height. Ensuring scintillometer's function of determining the location of radioactive materials, identifying radionuclides from the recorded gamma spectra and dose rate within a limited range.

  • Two basic working modes: Survey, for radiation surveying, and Identification, for identifying the detected sources.

  • Survey mode is combined with simultaneous dose rate measurements.

  • Energy calibration of analyser carried throughout operating time, and only natural background                                        sources are used for set-up.
