Folks

In what range of total doses is this effect supposed to apply?

Cheers

That is my understanding, based on the paper Barbara linked to.  My two
houghts on it are (1) it would seem to fly in the face of Linear No
hreshold, and (2) they really need a catchier name for it, 'cause how
an you get any traction for an concept when its acronym is PEE?

Does this mean that it is more dangerous to have been exposed over a 
onger time period than to have received the same total dosage over a 
horter time period?

hink it means what I think it means.
