“…To prepare a radioactive filter source with no significant mass loading, the experimental sampling parameters are optimized according to the following steps: filters loaded with radioactive aerosols are produced in the ICARE facility described by Grivaud et al (1998) and Ruzer and Harley (2005) by filtering a cesium chloride aerosol of 4 g cm À3 density and 3.7 mm aerodynamic median activity diameter (AMAD) (geometric standard deviation s g ¼ 1.4) tagged with 239 Pu. The flow rate across the filter is measured and regulated to achieve the required filtration velocity between 0.1 and 1.5 m s À1 .…”

“…The ICARE facility was designed in the mid1980's [11] to test continuous air monitors under representative operating conditions to determine the monitor response and the effectiveness of radon compensation [12]. The ICARE facility is composed of a 120 mm diameter air duct in which filtered air circulates at a controlled flow rate of approximately 56…”

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 m and 10 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.The first part of the article will present the general operating principles of continuous air monitors (CAMs) and inherent measurement difficulties, as well as the main standard tests. The second section describes the experimental ICARE facility; the ICARE facility generates standard artificial and natural radioactive aerosols for calibrating continuous air monitors under real operating conditions. Test results from two general types of monitor available on the market are also presented.
