Abstract
A device is provided for permitting real time measurement of the activity of dust confined in a ventilation duct. The device includes a radiation emitter for producing a beam for traversing the duct and a light radiation detector placed in front of the beam. The device also includes at least one gamma radiation detector placed facing the ventilation duct. An acquisition unit and a control unit are also provided for acquisition and processing of real time dust activity measurements. Particular utility is found measuring activity of dust leaving a furnace used for melting nuclear installation scrap.
