In the experiments of Dr. William L.
Russell at
the Oak niage National Laboratory, it was observed that the
induced mutation frequency at low dose rates was about 1/3
that observed at high dose rates.
by the BEIR Committees.
The factor of 1/3 was used
However, Dr. Mary F.
Lyon, et al., have
analyzed the Russell data along with additional data from
experiments at low dose rates.
Their analysis shows that
as the dose rate dross below some 0.01
