    Description

    A compact search device with a telescopic rod for quick detection and localization of alpha, beta, gamma and X-ray radiation sources.

     

    Purpose of Use

    • Measurement of ambient dose equivalent rate (DER) of gamma and X-ray radiation (photon-ionizing radiation)

    • Measurement of surface beta-particles flux density

    • Measurement of surface activity of beta-emitting radionuclides

    • Measurement of surface alpha-particles flux density

    • Measurement of surface activity of alpha-emitting radionuclides

    • Indication of pulse counting speed from the detector of alpha-beta-gamma radiation

    Features

    • Alpha-beta-gamma-sensitive Geiger-Mueller counter with mica window

    • Energy-compensating filter, which allows to obtain a reliable energy dependence of the radiometer readings when measuring photon ionizing radiation in the energy range from 12 KeV to 3 MeV

    • Large display with luminescent backlight, which provides simultaneous display of measurement units, measurement errors, threshold level, real-time; and an analog indicator of instantaneous radiation intensity

    • Ability to perform measurements with a preset error

    • Prompt evaluation of gamma background within 10 seconds

    • Automatic subtraction of gamma radiation component when measuring beta radiation parameters

    • Automatic subtraction of gamma and beta radiation components when measuring alpha radiation parameters

    • Programming of threshold levels of the alarm system activation for each parameter of measured radiation

    • Automatic setting of measurement intervals and ranges

    • Audio signaling of each registered gamma quantum, alpha or beta particle with the possibility of its deactivation

    • Two-tone audio alarm of exceeded programmed threshold levels

    • Recording in nonvolatile memory up to 1 000 measurement results

    • Viewing the measurement results previously recorded in non-volatile memory on the indicator, as well as transferring the information to a personal computer via Bluetooth

    • Four-level indication of the battery discharge

    • New software has been developed to work with the device

    • Software is used for:

      – readout of measurement results from the dosimeter memory into the PC as a dosimeter measurement protocol

      – viewing measurement results on the PC monitor, preparing and printout of reports, saving measurement results to a file without changes or as a report for further use
