Performance Assessment on Continuous Air Monitors Under Real Operating Conditions

In the nuclear industry, workers may be exposed to artificial radioactive aerosols. These aerosols are generally composed of particles with a diameter between 0.1
$\mu{\hbox {m}}$
and 10
$\mu{\hbox {m}}$
. To protect workers in nuclear facilities, monitors continuously measure radioactivity in the air. The main function of the monitor is to provide real-time measurement of activity concentration. Measurement of aerosol activity concentration can be affected by a number of factors specific to the aerosols and the instrument.
