Acute Exposure 16 : Radiation and Radiological Disasters. See: Exposure Situations. The aerodynamic diameter of an airborne particle is the diameter that a sphere of unit density would need to have in order to have the same terminal velocity when settling in air as the particle of interest. The thermodynamic diameter of an airborne particle is the diameter that a sphere of unit density would need to have in order to have the same diffusion coefficient in air as the particle of interest
