Formulation of the male and female value requires the assumption that the
body organs and tissues of the infant are shrunken versions of an adult.
This
approach is acceptable for the total body targer and total dody source configuration but may lead to significant differences from the true value if applied to
specilic tissues, especially active bone marrow.
This is due to large differ-
ences in active Sone marrow distribution in the infant relacive to the adult.
Although numan ailk samples were not taken while the Marshallese resided
on Bikini Atoll, body burden measurements were conducted on the adult copulation
