Problem 43
Q

A cancer patient is undergoing radiation therapy in which protons with an energy of 1.2 MeV are incident on a 0.20-kg tumor.

  1. If the patient receives an effective dose of 1.0 rem, what is the absorbed dose?
  2. How many protons are absorbed by the tumor? Assume RBE ≈\approx 1.
A
  1. 1.0 rad1.0 \textrm{ rad}
  2. 1.0×1010 p1.0 \times 10^{10} \textrm{ p}
