For personnel being monitored outside the general radiation
field where personnel contamination exists over relatively large
areas of the EXPOSED body (one-half square foot or more):
When the reading of a survey instrument held with the
center of the probe or center of the ionization chamber
four inches from the center of the contaminated area,
equals or exceeds the values given in Graph III it is recommended that personnel be advised to bathe and to change
clothing.
For personnel being monitored outside the general radiation
field where personnel contamination exists over relatively small
areas of the EXPOSED body (less than one-half a square foot):
The recommended maximum values are one-half those given
in Graph IIT. Monitoring of the head, arms, hands, lower
legs, and feet will be considered as coming under this
category. Washing may be limited only to the contaminated
paris, and also a change of clothing may not be indicated,
unless the radiation levels exceed those stated below concerning monitoring of exterior surfaces of clothing.

If this action does not reduce the radia-
tion levels to twice those given in Graph III or less, then
