  • Title: Microdosimetric characteristics of proton beams from 50 keV to 200 MeV.
    Author: Chen J.
    Journal: Radiat Prot Dosimetry; 2011 Feb; 143(2-4):436-9. PubMed ID: 21177271.
    Abstract:
    Proton beams are of growing interest for radiation therapy due to their special physical and radiobiological properties. Microdosimetric characteristics of proton beams have strong influence on the relative biological effectiveness for each biological system. This study focused on the microdosimetric characteristics of monoenergetic protons from 50 keV to 200 MeV. Monte Carlo techniques were used to simulate track segments of protons in water. Dose mean lineal energies were derived to characterise proton beams with changing kinetic energy and changing radiation qualities at various depths and within spread-out Bragg peaks of clinic interests.
