IKARthmb

Radiometer IKAR is a portable Radiometer with digital display readings.

Radiometer intended for measuring volume activity of radon-222 in the air and control of temperature, pressure and humidity.

The radiometer is used by radiation monitoring services in industry and medicine.

The radiometer is recommended for:

- measuring of volume activity of radon in exploited industrial buildings, residential buildings as well as commissioning new buildings and structures;

- measuring of volume activity of radon in the ground the alleged gas output during the various types of work;

- depth study of patterns of receipt of radon in indoor air in various geological conditions, including long-term systematic observations of typical buildings;

- identifying areas of radon income (for localization).

As the detector in radiometer using an ionization chamber.

Radiometer is a portable device consisting of a measuring device YI-02 and the power supply.

Measuring device YI-02 is produced in the form of a monoblock with a handle. The structure of the measuring device YI-02 includes the following components of nodes:
- detector (ionization chamber IC-01);
- pumping node UN-01;
- amplifier unit PUI-08;
- information processing unit POI-36;
- indicating node PIC-29;
- key node PKK-12;
- battery node UA-01;
- corps.
