title: Radiation damage in stained catalase at low temperature.
abstract: Radiation damage, which occurs in the beam of the electron microscope, has been studied in uranyl acetate stained crystals. Damage is observed in terms of the disappearance of higher orders of the electron diffraction pattern. In this study it has been found that the damage at very low specimen temperatures proceeds both more rapidly and to a greater final degree than is the case at room temperature.
