<prompt> About Bragg peak effect of protons all are true except:Electromagnetic radiationProduce ionization in biological systemThe dose of a single beam is two to four times greater than the path doseBeam therapy for AV malformation of the brain  <response>: Ref. Grainger and Allisons Diagnostic Radiology. Page. 30 Bragg PeakThe Bragg peak is a pronounced peak on the Bragg curve which plots the energy loss of ionizing radiation during its travel through matter.For protons, α-rays, and other ion rays, the peak occurs immediately before the particles come to rest
