Dear David and Other Radsafers:
I caught the same interpretation initially, and then realized that it could
mean "low level radiation damage", which would be caused by moderately HIGH
levels of radiation absorbed dose, as opposed to "damage caused by low
levels of radiation". I don't honestly know which meaning applies, but
given the source, which is a reputable group, I assumed that it referred to
low level burns, etc., which would be caused by moderately high levels of
absorbed dose. Perhaps AFRRI can clear it up.
Ciao, Carol
