Impact of the activity of cesium-137 in the bomb on the committed effective dose (50 years) and the equivalent dose absorbed in the first 10 days by the red bone marrow (RBM) in a victim in the vicinity of the detonation point (within 150 m) depending on the distribution of particle sizes (upper figures a and b: effective dose for 20% or 100% of small 5 µm respirable particles, respectively; lower figures c and d: RBM dose for 20% or 100% of 5 µm particles, respectively) and the evacuation time. The given doses are the sum resulting from external irradiation (“ground” and “cloud shine”) and the incorporation of radioactive material by inhalation. Assumptions: aerosolisation of the radioactive material 90%, plume height 30.5 m. Assumed deposition velocity for smooth surfaces: 0.3 m/s for 100 µm and 0.002 m/s for 5 µm particles [80]
