Radiometer Gorin-RKGB-01 (RKGB01, RKGB 01)
Radiometer Gorin-RKGB-01 is designed for personal radiation monitoring people on the ground, in homes and workplaces.
It provides the ability to measure the power of field equivalent dose of gamma radiation flux density measurements of beta radiation from the surface, contaminated with 90 + of the specific activity of the radionuclide cesium-137 in aqueous solutions, as well as chime in excess of the threshold power of the field equivalent dose of gamma- radiation that is installed by the consumer.
As a sensor of ionizing radiation in the device dosimeter-radiometer Gorin-RKGB-01 uses two types of gas-discharge counters SBM-20 in parallel, according to the pulse pattern.When injected into the working volume of the counters of ionizing particles appear at the load counter pulse repetition frequency is proportional to the dose rate of gamma-radiation flux density, or beta radiation.
The pulses of counters, limited in amplitude received during the measurement interval, the pulses are fed to the counter, and then to liquid crystal display.
The time intervals of measurement are set timer and frequency divider.
After the end of the measurement device emits an intermittent sound and captures the measured value.
