It has been reported that divalent lead ions coprecipitated with silver bromide increases the x-ray sensitivity of a photographic emulsion and decreases the degree of solarization. It was found that there is a close correlation between solarization by light and sensitization to x rays. It was hypothesized that if the heightened x-ray sensitivity were a consequence of keeping positive holes from recombining with electrons, solarization would be decreased. With this in mind, the sensitization of silver bromide emulsions to x rays by other metal salts such as thallous nitrate and thallous bromide, and the solarization of the emulsions thus sensitized, were studied. The thallium salts sensitized the emulsions to x-ray exposure but not to light, and decreased or eliminated solarization by light. (auth)
