The sexiness dose rete from all
il 32 prad/hour dus to natural becksround,
Consirembly the internal
whole body dose fron cel? was 0.2 prod/hour and that te bone from
sr” yas 0.3 pradfnour
The total interne] dose being on the order of
one third that arising from external fission products.
As expected,
after a fey years the bulk of the external dose is dus to ce? ,
The integral 30-yeer and 7O-venr uhole body dosa to man from
faliowt radioactivity vers caleulated for the present aituabion in
which thare has been no further testing sizes the fall of 1958.
These
doses have been termed the gensiically significant doses and the lifsetins
doze reepsctively.
The whole body dose is composed of an external
eomponent, attennated by the proper shielding factor, and en internal
eomponsnt arising from os?7,
An additional source of radiation to
bone exists due to the presence of sr2C,,
The external dose was
eomputed using two agssumptiona: (A) a shielding feetor of 5 for all
radionuclides, and (B) a shielding factor of 5 and a weathering factor
of 2 for cs)7,
The internal dose from Cs
ageumpiions; (C) the Cs137

aiso involved two
ody burgen is proporticnal to fallout
rete, and (D) the os? body burésa is proportional to the ascumilated
Cal? gsyositicn.
Depending upon the assuaptiona considered, the
30 year dose lies botveen 42 and 173 wrads end the 70 year dose betyoen
48 and 170 meads.
