receive no more than l0r man-made exposure to radiation to the
germ cells prior to the age of thirty no serious consequences

would result,

They, therefore, recommended that no one should

receive a total accumulated dose to the reproduction cells of
more than 50r prior to the age of thirty without clear cut
medical reasons and that in

any event the average exposure

of populations as a whole should not exceed 10r by the age of
thirty,

They point out that at present about 1/3 this figure is

already being used up by medical x-ray exposures many of which

could with proper precautions be greatly reduced,
As to occupational exposures the Committee considered this
to be a limited group - no estimates were made as to its actual
or potential size,
As finalized in the report the recommendations are:
1, There should be a national system of keeping radiation
exposures on all persons as is now practiced at AEC

establishments.

2, Medical exposures to the germ cells should be reduced,
3, No more than 10r by age thirty for the population as
a whole,

4, The subject should be reviewed periodically with a

vlew

to possible further reduction in exposure.

5. No body, however, employed, should receivenpre than
50r of exposure prior to the age of 30.

6, For special activities inherent in which are a

greater liability to overexposure individuals who for one
reason or other are unlikely to procreate should be
sclected,
7. The state of knowledge in the field of genetics has
been outrun by our knowledge in the field of physics,
8, Keep all exposures to the germ cells as low as

possible for radiation exposure is generally detrimental
to living cells,
In essence,

cn the subject,

this Committee formalized the current thinking

It did not come up with any new or startling

conclusions or recommendations.
