Aerosol Particle Resuspension Studies from Human Body Surfaces for Exposure Assessment

Ann McDonagh and Miriam Byrne

This abstract describes a study in progress which examines the process of resuspension of radioactive particles from human body surfaces for which limited data currently exist. Skin, hair and clothing are currently being ‘contaminated’ with tracer particles, which will then be worn by volunteers engaged in various everyday activities. Tests will then be carried out to determine the proportion of the original deposit which has been resuspended, as this increases a person’s whole body dose following accidental or deliberate airborne radioactive releases. These data will be used to refine models for radiological exposure assessment.
