HYDROTELERAY rivers monitoring network (France)
|Abstract||Since 1993, the HYDROTELERAY alert network ensures the radiological monitoring of 7 major French rivers, by performing continuous measurements of gamma radiation in water.|
Each station realizes continuous water sampling, with a flow rate between 6 to 10 m3 h-1. An immersed gamma spectrometry probe (sodium iodide detector) achieves 2 hours-integration direct measurements. The measurement data are automatically transferred to the supervising system located at Le Vésinet IRSN center.
In 2010, 4 new aquatic spectroscopic probes were added to the network, that are very compact, standalone and movable. They can be easily settled in various locations for specific temporarly studies.
