Michael,

What 20-30 minute burn time? I have had........75 daily radiation treatments in the past 3 years and none were more than a few minutes on the table. The only exception would be the radio surgery, that was 2 X 25 minute treatments in a 1 hour period which targeted 17 spots in a 1 innch area. You DO understand that the treatments are nothing like the simulation. You will feel the cumulitive damage over a period of time, not the rads. And Gary is, as always , correct, the mask will loosen quickly.
