The basis of the radiometer put gamma-spectrometric method for the determination of radionuclides, based on measurements of the pulse height distribution of radionuclides in the study of recorded energy ranges.

Radiometer is a stationary device, consisting of the following units:

• Lead defense (1 pc. single-channel radiometer, 2 pcs. radiometer for two-channel); • detection unit BDEG-01D (1 pc. single-channel radiometer, 2 pcs. for dual channel radiometer); • Amplitude conversion block BPA-01D (depending on order, available as part of a personal computer or in a separate building); • personal computer

Protecting a lead is protected from the influence of the surrounding natural background in the measurement process.

The detection unit converts the stream of gamma radiation in a sequence of pulses corresponding amplitudes. At the end of the detection unit is well to place the sample analyzed.

Block-01D converter converts the amplitude of pulses from the detecting unit into digital code and transmits them to the PC. The transducer block has two independent processing channels, it simultaneously be two detection unit. Depending on the order, the payment of the transducer block BPA-01D is set in a free PCI-slot of a personal computer or in a separate enclosure. Exchange of information via COM-port.
