ANALYSIS OF RADIATION DAMAGE TO ATM FILM.
Russell D. Shelton, A.C. de Loach · NASA Technical Reports Server (NASA) · 1967
Since Apollo Telescope Mount ( ATM) photographic film will be subjected to a proton flux during the mission, potential radiation damage must be analyzed from that standpoint.Proton dose rates are calculated as functions of orbital inclination, altitude, and shielding thickness; film sensitivities to proton radiation are determined experimentally.Film darkening is then expressed a s a function of elapsed time in orbit.It is concluded that several ATM films would not survive the radiation environment; research and test programs a r e underway to provide substitute emulsions that can be protected with a modest shielding requirement.
