In addition there would be a few chromosomal defects and
recessive diseases and a few congenial defects due to a single
gene defectg and chromosome aberrations.

The total incidence at equilibrium is 1100 to 21{000/year.

These

at equilibrium,the maximum would be 0.75% or 0.15% in the first generation.

e

These are equivalent to 0.15% per rem at equilibrium and 0.03%/rem

in the first generation.

b. Based on Overall Il] Health
Overall i1] health:

5% - 50% of ill health is proportional to the

mupation rate using 20% and doubling dose of 20 rem, 5 rem per generation
would eventually lead to a 5% increase in il] health.

Thus the rate of overall i1] health is 1%/rem at equilibrium or 0.2%/rem
in first generation.

For estimating the potential genetic derived health defects in the Bikini
population it was decided to use a risk coefficient of 0.2% per rem in the
.

first generation recognizing that it was probably very conservative.
