an accident wherein surfaces are contaminated with hot
particles, it is necessary to have a standard to apply to
decontamination measures,
The number of particles that can be resuspended from
surfaces has been the subject of a number of experiments.
These experiments have usually resulted in the datermination
of a resuspension factor
(RF).
The RF is defined by:
RF (m7) = concentration in air (uCi/s3)
