SLIDE 32 External absorbed dose adjusted for living pattern. The Marshallese reported no significant deviation from routine living patterns (see interview's recorded by Sharp Sh57). Miltenberger (Gr77), In a previous document by Greenhouse and it was shown by them that external exposure inhomogeneties due to various living patterns (such as fishing in the lagoon, standing on the beach, etc.) could be accounted for by miltiplying the mean exposure rate for the island by a factor to obtain whole-body absorbed dose rate. Another mltiplicative factor used by us was a correction for the electron density difference between air and tissue. Another factor used by us was one which accounted for attenuation and build-up of the photon flux as it traversed the body. The energy spectra assumed by us was that given by Borg (Bo56) for BRAVO fallout at four days. The total multiplicative factor used by us, to convert the average island exposure during the acute phase to whole-body absorbed dose, was 0.7. m 34
