Abstract

Summry form only given. Investigations on determination of a transmission factor of quartz fibers at their irradiation with a high-power pulse of an ionizing radiation are carried out. Length of an x-ray pulse is ~10 ns. The measurements were carried out with several wavelengths of a sounding light radiation of 0.68 mum, 0.82 mum, 0.94 mum. Light absorption factors are determined depending on the x-ray radiation doze, the wavelength of the sounding light radiation and a composition of alloy additions. The investigations showed that the absorption factor value decreases with increase of the wavelength of the laser radiation.
