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KDU-6BM is a state-of-the-art development replacing the outdated Soviet KDU-6B unit, which, unlike its predecessor, allows taking measurements ranging from background values, as well as more accurate determining of the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

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

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
