Le présent document porte sur la surveillance de la concentration volumique des gaz radioactifs. Ils permettent le calcul des rejets d'activité, dans les effluents gazeux libérés par les installations produisant des radionucléides et des produits radiopharmaceutiques émetteurs de positrons. De telles installations produisent des radionucléides à courte durée de vie qui sont utilisés à des…

These international guidelines are based on the assumption that monitoring of environmental components (atmosphere, water, soil and biota) as well as food quality ensure the protection of human health[2][4][5][6][7][8]. The guidelines constitute a basis for the setting of national regulations and standards, inter alia, for monitoring air, water and food in support of public health, specifically…
