. @la4 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.
