[ RadSafe ] The Role of Low-Dose Radiation in the Maintenance ofLife

[John Jacobus]

Jim,
I am not sure what we all know.  My point is that the
mechanisms for cell, and particularly cancer cell
repair is not clear.  You say the low doses of
ionizing radiation "stimulate" repair enzymes.  What
if the same radiation stimulates cancer stem cells? 
Are you saying that could not happen? Cells and their
interactions are complex, and I doubt all repairs
actions are beneficial.  Do you?

By the way, you really do not have to defend Dr.
Scott.  I am sure that if he wants to respond to me,
he will do so.
