SUBJECT:

LETTER FROM C. C. GOODALE TO SENATOR ENGLE (COPY TO REPRESENTATIVE CLAUSEN)

RFS:SB:JJH (IV)

The paragraphs below can serve as a portion of the reply to i

C. C. Goodale's letter of March 3, 1963.

1 I

l L u L itec e 760 micromicrocuries of I-131 per liter of. milk would be in upper Range III. This concen-i tration of radioiodine in milk would put transient daily

~

i~-

intakes into Range III only under the circus. stances postulated by the Federal Radiation Council in its Memorandum for the President, dated September 26, 1961.

In its memorandum, the Council reconsnended that guidance i

on daily intake be adopted for normal peacetime operations to be applied to the average of suitable samples of an exposed population group. In the case of I-131, the q

U' suitable sample would include only small children. For adults,, the Radiation Protection Guide (0.5 rem per year) for the thyroid would not be exceeded by rates of intake higher than a factor of 10 than those applicable to small

children, i c,)

Thus the milk referred to in the tear sheet of December i

l 25, 1962 would put transient daily intakes into Range III only for those small children who consumed enough of the j

milk so that their radioactivity intakes were greater than i

100 micromicrocuries of I-131 per day, w
