Problem statement: The dispersion of radioactive materials in the environment related to escaping of noble gases, halogens and aerosols of non-volatile radioactive materials, from the reactor containment during normal operations, or in the event of a sever reactor accident. Approach: radionuclide dispersion in the environment is demonstrated by mathematical tools which are the partial differential equations, mainly the diffusion equation. A mathematical model to calculate the concentration of nuclear pollutants (radioactivity) with certain boundary conditions is constructed. Results: Solving the mathematical model and using some approximations lead to a distribution represents a model for plume of radioactive pollutants dispersed in two dimensions normal to the wind direction in which the plume moves as an entire non-dispersible unit. Conclusion: The obtained result theoretically are very close to those achieved experimentally.
