Impact of the evacuation time on the committed effective dose (50 years, a) and the equivalent dose (b) absorbed in the first 10 days by the red bone marrow (RBM) in a victim of a bombing in a confined space as a subway. The given doses are the sum resulting from external irradiation (“ground” and “cloud shine”) and the incorporation of radioactive material by inhalation. Assumptions: Activity 2300 Ci, aerosolisation of the radioactive material 90%, size of the subway wagon: length 115 m, width 2.90 m, height 3.60 m. Assumed deposition velocity for smooth surfaces: 0.3 m/s for 100 µm and 0.002 m/s for 5 µm particle [80]
