[Importance of the role of dose rate on tumor induction in rats after radon inhalation]. / Importance du rôle du débit de dose sur l'apparition des cancers chez le rat après inhalation de radon.

Lung cancer can be induced in rats, by radon daughter products, after exposure as low as 25 WLM (80 mJ.h.m-3) protracted over 4 to 6 months with a dose rate of 100 to 150 WL (2 to 3 mJ.m-3). The incidence of lung cancer is not increased and is equal to that of controls when the same cumulated dose is protracted over 18 months at 2 WL (0.042 mJ.m-3).
