Short summary
This study shows that electrostatic dispersion can influence the time evolution of the charge and size distributions of radioactive and nonradioactive particles in the atmosphere. Three approaches with different levels of complexity are proposed to couple electrostatic dispersion with microphysical and radiological processes. These approaches can be useful to better understand the behavior of particles in atmospheric systems containing radionuclides.
