.

Basic FRC numerical guidance and health protection philosophy are
similar to those of the ICRP and NCRP.
(RPG's) are provided which deal with

population groups.

Radiation Protection Guides
exposures of individuals and of

Actions are to be directed primarily toward control

of the sources of radioactivity to restrict entry into the environment
but also toward control of radioactive materials after entry into the
environment in order to limit intake by humans.

The RPG's express the

dose that should not be exceeded without careful consideration of the
reasons for doing so.

Every effort should be made to encourage the

maintenance of radiation doses as far below this guide as practicable.
The RPG's are intended for use with normal peacetine operations.

Censidering such benefits, exposure at

the level of the 27G is considered as an acceptable risk for a lifetine.
The RPG's for the population are expressed in terms of annual exposure,
except for the gonads, weere the ICR? recommended value of 5 rems in 33
years is used.

FNC states that the operational mechanisn described for

applicaticn of criteria to limit the whole body dose for individuals to
0.5 ren per yeer and to linit exposure of a suitable sample of the
population to 9.17 rem per year is likely to assure that the gonadal
exposure guide will not be exceeded.

The child, infant, and

unborn infant are identified as being more sensitive

to radiation than the adult.

Exposures to be compared with the guidance

are tc be derived for the most sensitive members in the population.
