RE: Why effects of LDR differ from metabolism

Ted,

So you agree with me that radiation exposure at low dose and low dose rates

do not have a significant affect on the body?

Subject: Why effects of LDR differ from metabolism



. . .

But that doesn't apply to the chronic doses received by radiation workers,

downwinders, and people living in high natural radiation areas.  In those

cases, the difference results from the fact that the metabolic effect

diffuses throughout the body in a steady flow, like the light of the full

moon.  But radiation affects the body more locally in space and time, like

flashes of summer lightning.  Dr. Sukosky explained it well in his earlier

post (excerpted below).  For a given cell that is, or is not, struck by

radiation, the effect is very attention-getting, even though comparatively

fewer cells are affected.



There are intercellular reactions which play a part, but ultimately a cancer

initiates (or not) in individual cells.
