The sensitivity of nuclear emulsions to electron radiation is increased by triethanolamine and organic compounds which have the radical (CH/sub 3/)/sub 2/ N--C/sub 6/H/sub 4/--CH = CH--. The socalled optical sensitizers have no effect. The sensitization effect of 2-p-dimethylaminostyrylbenzthiazol (2-p-D) depends on the concentration of material used, on the dispersity of the silver halide crystals, on the AgI content in the silver halide crystals, and on the p Br/sup -/ value of the emulsion. It is not affected by the Cd/sup 2+/ content in the AgBr in using AgBr emulsions or by the chemical mataration time. The photographic characteristics of nuclear emulsions sensitized by 2-p-D change with time. The sensitivity of the sensitized emulsion layers decreases during the time between production and exposure, whereas the sensitivity of unsensitized emulsions does not. Nuclear emulsions sensitized by 2-p-D record not only the tracks of strongly ionizing particles but also electron tracks from C/sup 14/. The experimentally obtained dependence of sensitization of nuclear emulsions on the use of 2-p-D is explained. (tr-auth)
