Properties of fiber optical materials after exposure to nuclear radiation

The theoretically expected effects on fiber optical measuring samples, after exposure to nuclear radiation, such as /spl alpha/, /spl beta/, /spl gamma/ and flux of neutrons, were analyzed. Different optical fibers were tested: each of them was made of various materials and had different origin. Infrared (IR) spectra of these optical fibers, and their junctions (made by splicer), mere obtained before the exposure and after the exposure to nuclear radiation. The mechanical characteristics were measured too. The obtained results were used in the setting procedure of fiber optical characteristic.
