As I
recall from the hormesis (hockey stick) curve, the turn from benefit to “detriment”
is actually a reduced benefit from 50 rem up until it reaches zero at 100 rem,
where detriment actually begins. Jack

(cGy, rad here) is easily remembered "off the top of the head" as the
average CT dose, according to my local hospitals with new GE and Phillips
machines. That one rad/year is also about 10 x the
"low ambient" dose and 1/50 the "threshold" of benefit to
harm (Luckey). These are points of reference that I hope HPs will increasingly
use for technical advice about a potent medicine. Howard Long AndrewsJP@AOL.COM wrote: In a message dated

said the dose will likely prove to be within federal guidelines, which amounts
to about 1 1/2 to 5 times the amount of radiation produced by a single CT Scan. And we
all know off the top of our head what the "amount of radiation produced by
a single CT scan" is. |
