Question
Why do X-rays and gamma rays have equivalent RBE values if they provide different amounts of energy to the body? Please explain the correct answer to me. The answer choices are as follows.
a. Penetration distance, which depends on energy, is short for both x-rays and gamma rays.
b. penetration distance, which depends on energy, is long for both xrays and gamma rays.
c. penetration distance, as determined by their high mass, is different for both xrays and gamma rays.
d. The penetration distance, as determined by their low mass, is the same for both xrays and gamma rays.

b. penetration distance, which depends on energy, is long for both xrays and gamma rays - Correct Answer
c. penetration distance, as determined by their high mass, is different for both xrays and gamma rays.
d. The penetration distance, as determined by their low mass, is the same for both xrays and gamma rays.
Explanation: X-rays and gamma-rays have have extremely short wavelengths, have more energy and no rest mass therefore, these radiations go deeper into the material and are very penetrating. Moreover the extent or degree of penetration depends on energy leading to increase in penetration with more energy.
