90sr, and
13?cs.
The standard deviation on this ratio is 154.
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 population. The population mean dose equivalent and maximum dose equivalent Likewise differed by a factor of 3. The population average daily activity ingestion rate and maximum value differed by a factor of 4. For the nuclides 137cs
and 657n, a substantial sub-group in the population, children and infants,
received a dose equivalent higher than the population mean value.
