Okay
Coming around the curve, we find the front runners are

Looks like Medals for all so far in the Radiation Olympics .

BUT I've decided to keep this race open a little while longer so that the infrequent posters and lurkers can still enter.
Plus this thread is serving an important purpose: encouraging posters who already have had radiation treatment to go back to their doctors and get their actual GY count. Just be sure that's its apple and oranges. If your doctor' records only has RADS, or cGY, we can convert it here for you into GY.
Radiation doses for cancer treatment are measured in a unit called a gray (Gy), which is a measure of the amount of radiation energy absorbed by 1 kilogram of human tissue.
