3. Continuous monitoring

This–must enable rapid reaction in the event of a radiological anomaly.

In view of this objective of rapid detection, the radioelements sought must be easily identifiable by the measuring equipment and, moreover, representative of an accident situation. Detection is therefore generally focused on beta/gamma emitters.

For specific installations, alpha emitters may be detected if they represent the most rapidly detectable part.

Continuous measurement is carried out at gaseous outfalls and at stormwater, industrial and wastewater outfalls.

Finally, this section also includes measurements of meteorological parameters, which are essential for crisis management in the event of an uncontrolled gaseous release.
