Based on ionization chamber
measurements conducted from 1975 through 1977 (GR79), an infane (age 0-4 years)
would have been exposed to a net average external exposure rate of 10.1 UR/hr
during the residence interval 1 September 1977 to 31 aAuguse 1978.
This ccrre-
sponds to a dose of 77 mrem due to external exposure.
Finally,
through use of the methods presented here, it is possible to eval-
uate the expected body burden and dose equivalent ccmmitments that infants, age
0 co 12 months, will or have received through adequate sampling of the adult female population and the food products to be consumed.
