KDU-6BM is a state-of-the-art development replacing the outdated Soviet KDU-6B unit

which, unlike its predecessor, allows taking measurements ranging from background values, as well as more accurate determining of the direction towards the detected radiation source (four detecting units have been applied instead of two).
The product is a part of the ship’s life support system and is designed to collect, process, visualize information about radiation environment aboard and determine the direction towards the source of radiation in order to take measures on crew protection from ionizing radiation and radioactive contamination, and ship maneuvering in the area that has been exposed to radioactive contamination from nuclear weapons, man-triggered disasters or other reasons.
Purpose of use.
Display of measurement results of ambient dose equivalent rate (DER) of gamma radiation obtained from the BDBG-6BM detecting units of gamma radiation.
Determining the direction towards the source of radiation.

Sound and light alarms of exceeding the gamma DER threshold levels

Law enforcement agencies Emergency Service s and Civil Defense Customs and Border Services Features.
Display of measured gamma radiation DER from 4 detecting units is simultaneous and continuous.
Application of the intelligent detecting units.
Detecting units have the function of the integrated detectors efficiency control with generation of check information .
Three-color digital indicators of measurement results have been applied.
Ability to automatically switch from the basic power system to the backup one without information loss.

In case of exceeding.

The concentrator unit changes the color of gamma radiation DER display

highlights the transparencies of the established direction towards the radiation source, and triggers audio alarm.
If the value of the gamma radiation DER measured by any of the detecting units exceeds 5 μSv/h, the concentrator unit lights up “IN ZONE” transparency.
