Accordingly, any dose limitations recommended
by the Commission refer only to exposure resulting from technical
practices that add to natural background radiation.
These dose Limita-
tions exclude exposures received in the course of medical procedures.
(These same qualifications with regard to natural background and
medical procedures are applied to NCRP and FRC recommendations.)

For plannedjexposures of individuals and populations, the ICRP has
recommended the term "dose limit."
aK
It is not desirable to expose members of the public to doses as high
as those considered to be acceptable for radiation workers because
children are involved, members of the public do not make the choice
to be exposed, and members of the public are not subject to selection,
supervision and monitoring, and are exposed to the risks of their own

occupations.
For planning purposes, dose limits for members of the

public are set a “£actor of ten below those for radiation workers.
The dose Limits for members of the public are a somewhat theoretical
