The results of the calculations based ufon the models described above
and upon the diets listed in i7VO-140 and altered for children as previously
discussed, are listed in Tables 1-8.
The data are presented as maximum
ot
annual bone-marrow and whole-body deses.
The living patterns are listed
after Tables 1 and 6 for convenience of reference; they are the same as
those listed in Nvo-140.
The annual doses for external exposure and for food chain exposure
from
137 Cs and 9 “sr are calculated for 7O yr, beginning at either age
locr ase 20.
The three different components contributing to the dose
produce a raxizun dose at dirferent times.
The external corrcnent, fer
instance, is maximum at lyr and decreases thereatter with the physical
half-life of ““'Cs and “Co; the effective decay depends cn the rarticulsar
dose several years after inteke of the nuclide tegins.
The year oF
upon whether or not a diet chanse is involved at some point
dosaze from
in time.
The
s incorporated in rman via food cheins tends to peak cariv
and decreases exponentially therearter.
The annual dose is then selectec
for the years at which the sun of these three comronents was rmaximur.
The meximur a@nnual bone-marrow doses are listed in Table 1 Tor the

source of the diet and no modifications are made for extern
