BAB A7

The Alpha and Beta aerosol beacon, BAB A7, is specially designed for work station monitoring during maintenance operations or in dismantling work sites, where man-made noise immunity is highly recommended.

Application center News

The BAB A7 continuously monitors and measures the concentration of artificial Alpha and Beta radioactive aerosols. As an option, it can be equipped with an external probe for the measurement of ambient Gamma radiation. All data measured by the BAB A7 are displayed in real time or remotely accessible. Its powerful algorithm allows an optimal compensation of Radon.

The beacon is available in stationary and mobile versions, to meet the various needs of its users, such as effluent or construction site monitoring. Versions compatible with VD/VR and Skylink communication standards are available.

Communication

ShortLINK or SkyLINK (radio), VD/VR

Option

External Gamma probe

  • Can be used in controlled areas with high gamma background
  • Compensation of radon progenies
  • Use of standard sources for efficiency controls
  • Ruggedized, can be used on dismantling and purification sites
  • Available as stationary or mobile version
  • Can be connected to a central monitoring network and trigger a general alarm
  • 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.
  • The SKYLINK wireless radio communication kit
  • Gamma radiation kit
  • GM-2N Gamma probe for monitoring of external exposure
  • GJNOV software for local maintenance and data acquisition
  • Wireless data transmission
  • VD/VR communication (CEA)
