BAB - air monitoring beacon
The BAB air monitoring beacon provides continuous measurement and monitoring of atmospheric contamination from radioactive α & β artificial aerosols, including compensation of radon progenies and ambient gamma radiation.
Can be used in nuclear industry, dismantling and purification sites as radiation protection for workers and environmental protection. Available as stationary or mobile version.
The radioactive dust is deposited by air suction on a filter paper placed in the BAB beacons. The suction flow rate is about 5 m3/h (it depends on dustiness and type of filter paper). The flow rate is calculated from the depression measured between the filter and the pump. This allows to detect any tear or dust clogging.
Placed one centimeter above the sample, the detection system is based on two 300 μm thick silicon diodes with a surface of 360 mm2. The analog signal from the two diodes is amplified by a preamplifier with an output range of about 30mV/MeV. An amplifier increases the signal amplitude to 0.7V/MeV, and the signal is then used to produce the energy spectrum via an amplitude analyzer that encodes information to 512 channels.
Detector head lead shielded for use in high gamma background.
Can be connected to a central monitoring network and trigger a general alarm (Wireless data link, ShortLINK or SkyLINK radio).
GJNOV software for local maintenance and data acquisition
The BAB air monitoring beacons are available in two different versions:
• BAB-A7 version is specially designed for work station monitoring during maintenance operations or in dismantling work sites, where man-made noise immunity is highly recommended. BAB-A7 is available for stationary or mobile use.
• BAB-E exists as stationary version for outside use, and will be typically used for surveillance around nuclear facilities or for national monitoring.
