Features

• measurement of gamma- and beta-radiation;
• sensitivity sufficient for correct measurements at the natural background level, combined with a high upper limit of dose rate measurement;
• use the device as the personal dosimeter in the automated systems for collecting dosimetry information due to the ability to transmit data on the accumulated dose;
• to save the accumulated dose values in the inner archive of non-volatile memory - up to 150 records;
• the ability to install from 1 to 3 alarm threshold values in case of exceeded these values the audible signal will be generated;
• control and change of parameters, both using the keyboard and using a PC with a specialized software;
• easy handling, the best price-quality ratio.

Purpose

The dosimeter-radiometer is designed to measure:

• ambient dose equivalent rate Ḣ*(10) of gamma radiation;
• ambient dose equivalent Ḣ*(10) of gamma radiation;
• beta flux density.

The dosimeter-radiometer is used in the services of radiation control, industry, medicine, scientific and others facilities where are applied the sources of ionizing radiation.

Technical specifications

• Measurement range:
  • ambient dose equivalent rate from 0,1 µSv/h to 0,1 Sv/h;
  • ambient dose equivalent from 0,01 µSv to 40 Sv; 
  • beta flux density from 12 to 10⁵ min^-1cm^-2.
• Energy range of detected gamma radiation from 0,05 to 3,0 MeV.
• Energy range of detected beta radiation from 0,12 to 3,0 MeV.
• Energy dependence of sensitivity of gamma channel in the range from 0,05 to 1,25 MeV no more ± 25 % relatively sensitivity to the energy of radionuclide radiation ¹³⁷Cs.
• Limits of the main relative error of the measurement:
  • dose rate — ±(20+2/Ах)%, where Ах - numerical value of the measured value;
  • flux density — ±(20+200/Ах)%, where Ах - numerical value of the measured value.
• Transmission of measurement results to the PC via USB according to protocol DiBUS.
• Set time of operation mode, no more 5 s.
• The dosimeter is powered by two galvanic batteries or AA batteries АА.
• Time of continuous operation from a freshly charged set of batteries, with a capacity of at least 2700 mАh — 700 hours 

Applicability factors

• Continuous measurement with constant refinement of the result.
• Estimate of radiation state by means of sound signals (clicks), the frequency of which is proportional to the dose rate (flow density).
• Measurement results with any required statistical error.
• Automatic restart of the device in the case of the change of radiation type during the measurement.
• Compensation of the count rate due to the presence of gamma radiation when measuring of the beta flux density.
• Indication of the statical error during the measurement process.
• Indication of unit of measurement.
• Indication of battery charge level.
• Highlighting display.
• Pocket size.
