Photographic Sensitivity of Silver Azide Emulsion

説明

Silver azide emulsions are prepared without ripening and their light sensitivity as well gamma-ray sensitivity are studied. Silver azide emulsions are developable by weak alkaline metol developers without sulfite, for example: metol 3 g, ascorbic acid 2 g, sodium carbonate 2 g, sodium chloride 1g in 1, 000 cc developer. Emulsions made of inert type gelatins show higher sensitivity than those with active gelatins, and addition of oxalic acid, tartaric acid, citric acid or acetic acid increase both the light sensitivity and the gamma-ray sensitivity. The emulsions are sensitive to gamma-rays emitted from a radioisotope of ⁶⁰Co having dose rate of 56, 000 r/hr, and become developable when the emulsions are exposed to a dose of irradiation of about 10⁴ to 10⁵ r.
