90sr, and
!37¢s.
The standard deviation on this ratio is 15%.
These ratios
were determined only when the body burden for the nuclide of interest had
reached a maximum.
Thus a significant time passed on Rongelap, 2 to 3 years
post return, before a body burden comparison was valid.
It was observed, in all cases, that the population mean body burdens
were lower by a factor of 3 than the highest for any individual in the popula-
tion.
The population mean dose equivalent and maximum dose equivalent likewise differed by a factor of 3.
The population average daily activity inges-
tion rate and maximum value differed by a factor of 4.
For the nuclides
and 6570, a substantial sub-group in the population, children and infants,
received a dose equivalent higher than the population mean value.
