Shipboard Radiation Monitoring System

KDU-6BM

ТУ У 26.5-22362867-036:2014

KDU-6BM is a state-of-the-art development replacing the outdated Soviet KDU-6B unit, which, unlike its predecessor, allows taking measurements ranging from background values, as well as more accurate determining of the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.
