Fig. 1From: Difference in the relative biological effectiveness and DNA damage repair processes in response to proton beam therapy according to the positions of the spread out Bragg peakDepth dose and linear energy transfer (LET) profiles of the Spread-Out Bragg Peak (SOBP) of a 235-MeV proton beam. The solid line shows the tissue maximum ratio across the depth, and the dashed line indicates the LETBack to article page
