Hi all! We are down to 2 rads left! Tuesday will hopefully be the last time he has to be held captive under that mask. I have a strange question, especially so late in the game. I am worried about it though and it won't leave me in peace. My husband never really completely got the lotions/Aquaphor completely off of his neck before rads. He would wash up but I could always see a very slight bit of shininess on his skin. I was wondering why they are told to have a clean neck. Does it interfere with the radiation beam? Now I am worried that it didn't penetrate the way it should have. Lord, I'm a nut....sigh.
