Abstract
WE report here the observation of a faint bluish green glow with a peak around 5000 Å when gamma-irradiated NaCl, NaBr, KCl or KBr is dissolved in distilled water. To observe the glow the room must be dark and the eye must be acclimatized to the darkness for a few minutes. A high speed (400 ASA) photographic film is blackened by direct exposure to the glow in about 10 min (Fig. 1).
