For internal exposures, personal monitoring devices consist of an air pump and filter to estimate the airborne radioactivity inhaled by workers. Such devices include personal air samplers (to measure airborne particulates generally) and personal alpha dosimeters (to measure radon progeny and uranium ore dust in air). 3, record 1, English, - airborne%20radioactivity

Dans le cas de l'exposition interne, les dispositifs de contrôle individuel consistent en une pompe à air et un filtre pour estimer la radioactivité en suspension dans l'air inhalé par les travailleurs. Ces dispositifs comprennent des échantillonneurs d’air individuels(pour mesurer les particules en suspension dans l'air en général) et des dosimètres alpha individuels(pour mesurer les produits de filiation du radon et la poussière de minerai d’uranium dans l'air). 1, record 1, French, - radioactivit%C3%A9%20en%20suspension%20dans%20l%27air

(...) vertical chambers - usually of circular cross-section - with grate hearths through which oxygen-bearing gas, usually air, is blown. As the concentrate is fed to the chamber, air is blown through the grate at a rate sufficient to hold the solid particles in suspension, the mixture of air and solids having the flow characteristics of a fluid. Since each sulfide particle is in constant turbulent motion in the furnace atmosphere, roasting is uniform and rapid, with efficient heat transfer and high oxygen utilization. 3, record 2, English, - fluid%20bed%20roaster

Dans les fours à lit fluidisé, le minerai [le zinc] est maintenu en suspension par l'air de grillage soufflé par le bas à un débit convenable. Dans certaines conditions, le lit de minerai en suspension se comporte comme un fluide; le contact air-particules de minerai est excellent, ce qui favorise la rapidité d’oxydation des sulfures. L'alimentation peut être constituée par du minerai fin ou granulé, la granulation permettant d’éviter un entraînement de poussière important. 1, record 2, French, - four%20%C3%A0%20lit%20fluidis%C3%A9
