to the upper limit estimate of the somatic risk of 1/16, and
this genetic risk,
like the somatic risk,
is excessive.
When
somatic risk and genetic risk are combined (on an equal weight
basis), the combination sugyests that the existing exposure
standard is at least 10
times too high.
In this Report we are
proposing a factor of 10 reduction in the genetic risk and a
factcr of 6 reduction in the somatic risk with the additional
request as stated previously that the exposures be kept as far
below the provosed naw limits as is practicable.
