About Bragg peak effect of protons all are true, except:: (A) Electromagnetic radiation, (B) Produce ionization in biological system, (C) The dose of single beam is 2-4 times greater than the path dose, (D) Beam therapy for AV malformation of the brain.
Answer is A. Ans. a. Electromagnetic radiationThe brag peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter.For proton, a-rays, and other ion rays, the peak occurs immediately before the particle come to rest.
