Decontamination is the process of removing fallout material from surfaces to reduce the radiation dose that would be received by anyone exposed to the fallout. The removal of such fallout is very similar to cleaning by ordinary methods. These methods include handbroom sweeping, mechanical street sweeping, mechanized vacuum cleaning, and firehosing. Physical models of cleaning processes are described and mathematical formulations are developed that relate the fallout-mass removal to time spent in the cleaning process for three cases 1 the layer to be removed is thin and no mass piles up in front of the cleaning equipment, 2 the layer is thick and no piling up occurs, and 3 the layer is thin or thick and piling up occurs. Recommendations are suggested for the conduct of any future decontamination experiments to obtain estimates of the values of basic-equation parameters. Author
