The purpose and technical characteristics of the gamma-ray radiometer ROG-M:

Gamma-radiometer ROG-91M ADANI "ADANI" is designed to measure specific and volumetric activity of gamma - emitting radionuclides Cesium-134,-137, natural Potassium-40 and Radium-226 and Thorium-232 in samples of the natural environment.

Technical data gamma-radiometer:

Scintillator-crystal Cs I (TI) size 40x40 mm.

The limits of permissible basic error of measurement of volumetric activity radionuclide potassium-40 when the measurement time is 20 min (0,2 – 50,0 kBq/l) -50%; 2 min (0.5 -50,0 kBq/l) – 50%.

Limits of additional error in the measurement of temperature 1%/1º C, when measuring the external background gamma radiation up to 50 Mr/HR -25%.

The time of operating mode setting, not more than 30min.

Continuous work time not less than one hour.

The sample volume is 0.5 l

The principle of gamma-radiometer ROG-91M ADANI based on counting the number of light pulses occurring in the scintillation detector at exposure to gamma rays. The number of registered per unit time of light pulses unambiguously linked to the activity of the investigated sample.

A simplified functional diagram for explaining the principle of operation of the radiometer. The investigated sample (sample) is placed in the cell, which use the Marinelli vessel with a volume of 0.5 l Cuvette with the sample placed inside a lead protective screen, which reduces the impact external background radiation. On top of the screen closes the lead a protective cover. Light flashes occurring in the scintillator, through the light falls on the photocathode photoelectron multiplier and converted into electrical pulses which, after amplification of the received in the device selection. Device selection sorting pulses according to their amplitudes(proportional to the detected energy gamma quanta). This allows you to determine porceline deposits isotopes cesium and potassium in the total activity of the sample. The processing device controls the operation of the device selection and calculates quantitative characteristics of ionizing radiation. A display and management sets the mode of operation of the gamma-radiometer and induces on the scoreboard the measurement result. The operation mode is set using the 14 buttons on the front panel of the device.

ATTENTION!!! In gamma-radiometer as the detector uses a crystal Cs I (T 1), which requires careful treatment. Avoid mechanical shock to the device and a sudden drop temperature!!!
