human effects of radiation

["H.Wade Patterson" <hwade@triax.com>]

Group:
At the HPS annual meeting there were arguments for and against the LNT
and similar models (hypotheses).

For your information,here's an interesting paper with findings that fail
to support the LNT and similar models (hypotheses). Quoting from
below:"No statistically significant effects emerge with respect to eight
different indicators."

The children of parents exposed to atomic bombs: estimates of the
genetic doubling dose of radiation for humans.
American Journal of Human Genetics, 1990 Jun, 46(6):1053-72.

Abstract: The data collected in Hiroshima and Nagasaki during the past
40 years on the children of survivors of the atomic bombings and on the
children of a suitable control population are analyzed on the basis of
the newly revised estimates of radiation doses. No statistically
significant effects emerge with respect to eight different indicators.
Since, however, it may confidently be assumed some mutations were
induced, we have taken the data at face value and calculated the minimal
gametic doubling doses of acute radiation for the individual indicators
at various probability levels. An effort has also been made to calculate
the most probable doubling dose for the indicators combined. The latter
value is between 1.7 and 2.2 Sv. It is suggested the appropriate figure
for chronic radiation would be between 3.4 and 4.5 Sv. These estimates
suggest humans are less sensitive to the genetic effects of radiation
than has been assumed on the basis of past extrapolations from
experiments with mice.
