[Radon risk evaluation in a hospital context].

Italian legislation imposes radon concentration in occupational, underground premises as to not exceed the annual action level of 500 Bq/m3. A survey in a hospital of Milan founded concentrations never exceeding the action level, distribute around the median concentration of 16 Bq/m3, ranging between 6 e 214 Bq/m3 (Cmean = 38 +/- 50 Bq/m3). However, a pavilion, characterized by higher levels (C = 103 divided by 214 Bq/m3), was better studied by short-term monitoring, during summer and winter, confirming concentrations not exceeding legislative level, even if not negligible.
