The dosimeter DKG-02U “Arbiter” with a wide measurement range and easily decontaminated hermetical case, suitable for operation in severe environment. The dosimeter indicates dose rate and dose (operator’s exposure) that makes it a convenient tool for performing radiation surveys under radiation accident conditions. While performing surveys of territories, buildings or equipment, the user can save measurement results in the dosimeter’s memory, add a comment (for example, name of measurement point) and transfer this information to a personal computer later, after the survey is finished.
measurement of ambient equivalent dose rate H*(10) of gamma radiation;
measurement of ambient equivalent dose H*(10) of gamma radiation;
counting of number of pulses from detected gamma radiation photons;
estimation of radiation levels with the aid of audible signals;
search (detection and locating) of gamma-radiation sources using the analog scale;
pedestrian gamma-survey.
Features:
high sensitivity;
wide measurement range: from natural background up to emergency levels;
«search» mode with analog indication (bar);
audible and visual alarms for dose and dose rate with preset thresholds;
shock-resistant, water-proof case and battery compartment allows easy decontamination;
memory for 100 measured values with date and time of measurement;
saving comments in memory;
storage of total dose accumulated during exploitation period in the non-volatile memory (total dose can not be erased by the operator).
