Gamma ray area dosimeter BAB A7

Alpha ray

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. 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.
