Committed effective dose (50 years) (mSv) and equivalent doses absorbed by individual organs and tissues (mSv) in a victim of a “dirty bomb” attack staying for 30 min (evacuation time) in the vicinity of the detonation point (within 150 m) depending on the distribution of particle sizes (5 µm respirable; 100 µm non-respirable). The given doses are the sum resulting from external irradiation (“ground” and “cloud shine”) and the incorporation of radioactive material by inhalation. Assumptions: activity of cesium-137 in the bomb 2300 Ci, aerosolisation of the radioactive material 90%, plume height 30.5 m (as given in the National Planning scenario Nr. 11) [19]. Assumed deposition velocity for a smooth surface: 0.3 m/s for 100 µm and 0.002 m/s for 5 µm particles [80]. RBM red bone marrow
