total annual exposure for comparison with FRC guides.
However, for
many practical situations a relatively few radionuclides yield the
major contribution to total exposure; by comparison ,exposures from
others are very small.

The term "Protective Action Guide" has been defined as the
projected absorbed dose to individuals in the general population which
warrants protective action following a contaminating event.

numerical guides the FRC was concerned with a balance between the

action should not be expected to occur frequently.
The numerical guides are related to three types of actions, (1)
altering production, processing, or distribution practices, (2) diverting affected products to other than human consumption, and
affected foods.
(3) condemning
An additional category involves long-term, low level
exposure for which numerical guides are not provided; the need for
action is determined on a case-by-case basis.
The FRC identifies the critical segment of the population for which
dose projections are to be made for comparison with the guides.
