Purpose and operation mode
|
|
A radiometer provides continuously measurement and transmission values of volume activity of iodine radionuclides I-131 by information network.
The operation mode is based on analyse of the energy spectre of gamma-quantum that are emitted by radionuclides which has left on the sorption-filtering material in the result of pumping air through it.
A radiometer measures the value of volume activity of iodine radionuclides I-131 that is calculated according to the algorithms of detection, accumulation and average hourly measurements.

Application areas
Continues automatic control of concentration of iodine radionuclides I-131 in the independent mode or as a part of automation radiation monitoring systems in the air of workplaces, ventilation systems, pipelines, chambers and etc.
Operation modes:
- a stationary measuring device with own pump block or with work from external sampling line;
- a portable measuring device on a trolley with pump block;
- a point of continuous control in a radiation control system with ability of transfer data to a local network.
Features:
- built-in air flowmeter;
- compensation of impact external gamma background with lead protection 5 cm thick;
- communication interface RS-485;
- an ability of air sampling from the ventilation system;
- setting by means of the console and notebook;
- ability of connection external block of indication and alarm.
- stationary or portable version with own pump block;
- work from an external sampling line.

Purpose indicators:
- a radiometer by purpose refers to the elements of the system of normal operation, the impact on the safety of nuclear power plants - to systems and elements important for safety, third class;
- analyse of energy spectre of gamma-quantum that are emitted by radioactive iodine isotopes which accumulate on the filter using a 1024-channel AD converter provides spectrometric determination of the volumetric activity of the radionuclide iodine I-131;
- a radiometer measures a consumption and volume of pumped volume of air by means of the built-in flowmeter;
- a radiometer controls its own pump block and can control external devices (for example, solenoid valves while working with an external sampling line).
