Context
Coastal nuclear sites, be it civil or military, are all equipped with environmental radiation monitoring networks. If radiation controls on the landward side are sufficient to guarantee a close area monitoring, most facilities lack radiation measuring equipment on the seaward side. To improve radiation monitoring on the coast, Bertin Instruments designed an autonomous station for marine radioactivity monitoring, consisting in two probes (GammaTRACER XL2-2 and SpectroTRACER Aqua) mounted on a buoy (GISMAN GBM-2000). Highly resistant, this floating station allows for continuous dose rate measurement in air and water, in extreme climatic and operational conditions (Strong waves, salty winds, fierce currents, etc.). It is also adapted to the monitoring of maritime borders, especially when the population needs to be protected from the nuclear risk caused by a neighboring country.
