The SiPM devices used in this study show a significant change in their behavior and downward shift of their breakdown voltage by as much as $\\sim$ 0.4$\\pm$0.1 V. Single photon measurements appear to be no longer possible for the SiPMs under study after exposure to a dose of $\\sim$ 0.2 Gy (corresponding to an integrated proton flux of $\\sim$$\\phi_{p}$=1.06x10$^{8}$ p/cm$^{2}$).
