This system provides the instantaneous and continuous measurement of the radioactivity of Krypton 85 gas in the atmosphere. One of this system analyses the ambient air near the French nuclear waste conditioning plant Cogema of La Hague. This system is exploited by the French Heath Ministry (Office de Protection des Rayonnements Ionisants (O.PR.I.). The main mission of this automatic system is the continuous measure of Krypton 85 gas radioactivity and to prevent authorities when measures are over pre-programmed levels. 

This system is automatic and sends periodically measures and alarms when they occur to a distant server located to Paris.

A dedicated .software Symakry allows to program and configure the system (system parameters, acquisition, alarm's levels, ...) from distance by telephone link. Instantaneous or recorded measures of the day or another day can be also consulted from distance by the operator.
