Prof. Cohen says:

"	-Pierce et al assume that the high dose and low dose effects are
due to the same dominant process. If different effects are important at
low dose, such as stimulation of the immune system, adaptive response,
etc, their analysis is irrelevant. There is good evidence that these
effects are important only at low dose."

Could you cite a few key references that show this "good evidence" of
effects that could alter carcinogenesis and are known to occur at low dose.
It is known that high acute doses stimulate DNA repair, but I haven't seen
any evidence at low dose (less than 0.05 Sv).

Thanks,

Otto
