Abstract
The induced damage effects of 14.3 Mev neutron fluxes on quartz-based porcelain and alumina-based porcelain were studied using X-ray diffraction analysis and electric, resistivity measurements. The results showed that both the degree of crystallinity and the electric resistivity of the samples decreased upon irradiation. Resistivity values plotted as a function of neutron flux proved to fit semi-empirical formulae that could be used for measuring neutron fluxes (1010−2 × 1011 n/cm2) in the presence of gamma radiation (up to 5 megarads). Moreover, plots of the area under the X-ray peaks as a function of neutron flux were found to fit empirical formulae which could be used for the same purpose. The effect of storage at temperatures up to 50°C and for periods of up to 2 weeks on the radiation induced changes in the porcelain were studied.
