CABINET PAPER—PRIVILEGED
Property of the White House—For Authorized Persons Only
The following points are made in relation to the Radiation
Protection Guides herein provided:
(1}
For the individual in the population, the basic Guide for
annual whole body dose is 0.5 rem.
This Guide applies
when the individual whole bodydses are known.
Ags an
operational technique, where the individual whole body
population should be developed whose protection guide ~
ean 2
/
doses are not known, a suitable sample of the expased
*,
for annual whole body dose wil! be 0.17 rem per capita ce}
per year.
It is emphasized that this is an operational
technique which should be modified to meet special
situations.
(2)
Considerations of population genetics impose a per capita
dose limitation for the gonads of 5 rems in 30 years,
Thr
operational mechanism described above for the annual
individual whole body dose of 0.5 rem ie likely in the
immediate future to assure that the gonadal exposure
Guide (5 rema in 50 years) is not exceeded.
(3)
These Guides do not differ substantially from certain
other recommendations such as those made by the Nationpl
Committee on Radiation Protection and Measurements,
the National Academy of Sciences, and the International
Commission on Radiological Protection.
(4)
The term "maximum permissible dose" is used by the
National Committee on Radiation Protection INCRP) and
the International Commission on Radiological Protection
(ICRP).
However, this term is often misunderstood.
The
words "maximum" and "permissible" both have unfortunate
connotations not intended by either the NCRP or the ICRP.
