The dosimeter-radiometer is designed to measure:

• The rate of the equivalent of the ambient dose H * (10) gamma radiation;
• The equivalent of an ambient dose of H * (10) gamma radiation;
• Beta radiation flux densities.
• It is used in dosimetric control services, industry, medicine, scientific and other institutions where ionizing radiation sources are used.

Features:

• Gamma and beta radiation measurement;
• Sensitivity sufficient for correct measurements at the level of natural background is combined with high upper limit of dose rate measurement;
• Use of the instrument as a personal direct indication dosimeter in automated systems for collecting dosimetric information due to the ability to transmit data on the accumulated dose;
• Maintenance of internal archive of accumulated dose values in non-volatile memory - up to 2000 records;
• Possibility to set from 1 to 3 values of alarm threshold levels, if they are exceeded, audio signal is generated;
• Control and change of parameters using both keyboard and PC using specialized software;
• Ease of handling, optimal price-quality ratio;
• Rear cover of the housing is equipped with a convenient window with a rotary device, the transition from gamma radiation dose rate measurement to beta radiation flux density is carried out by simple opening of the window.

Specifications:

• Measuring range:

The rate of the equivalent of the ambient dose from 0.1 μSv/h to 0.1 Sv/h;

Ambient dose equivalent from 0.01 μSv to 40 Sv;

Beta radiation flux density from 12 to 105 min-1cm-2.

• Energy range of detected gamma radiation is from 0.05 to 3.0 MeV.
• Energy range of detected beta radiation is from 0.12 to 3.0 MeV.
• Energy dependence of gamma-channel sensitivity in the range from 0.05 to 1.25 MeV is not more than ± 25% relative to 137Cs radionuclide radiation energy sensitivity.
• Limits of the main relative measurement error:

Dose rate - ± (20 2/Ah)%, where Ah is the numerical value of the measured value;

Flux density - ± (20,200/Ah)%, where Ah is the numerical value of the measured value.
