a cells maturity and rate of division CORRECT ANWER Proliferation what affects radiosensitivity the most? CORRECT ANWER Proliferation what does LET stand for? CORRECT ANWER Linear Energy Transfer describe LET CORRECT ANWER the rate at which energy is transferred to tissue as radiation (x rays, gamma rays, alpha particles, beta particles, fast neutrons) passes through; the more energy that is transferred, the more ionizations occur, which results in more biological damage; x rays and gam...
