Dispersion modelling
Calculation of radioactive dispersion
Dispersion calculations are carried out in the event of an incident in a nuclear power plant that represents a risk to humans:
These calculations predict the direction of travel of any escaping radioactive cloud. They are important because pre-emptive action must be taken to protect humans before any radioactive cloud emerges.
Secondly, if radioactive material does escape, the calculations identify which areas are likely to be affected by the radioactive cloud and when. This allows the targeted use of measuring equipment as in addition to dispersion calculations it is important to start local measurements immediately. Measurements are taken by permanent equipment (MADUK) and mobile measuring vehicles together with the use of special helicopters (aerial radiometry).
