DISCRIMINATION OF TRACKS OF PHOTOFISSION FRAGMENTS WITH VERY HIGH BACKGROUND OF ALPHA PARTICLES AND ELECTRONS IN NUCLEAR EMULSIONS

Technical Report ·
OSTI ID:4147649

With common chemicals used in photography such as Amidol, boric acid, sodium sulfite, and potassium bromide, a developing bath was prepared which permits a full discrimination between tracks of highly ionizing particles, such as fission fragments, in the presence of strong background radiation such as 1O/ sup 9/ alpha particles per cm/sup 2/ or by the electrons from a 2000-r x-ray source.
