Television imaging transducers for use in radiation fields

For optical television equipment widely used in nuclear energetics it appears to be importance to account for various radiation effects on the device material and units aiming at diminishing negative effects of radiation upon the devices operation. Basing on the experimental results (along with the analysis of literature data) the authors propose a mechanism of radiation effect upon television imaging sensors (TIS). Operation principles and construction of up-to date TIS are briefly described, as well as the characteristics of radiation conditions. Various radiation effects upon the TIS material and construction have been considered. Optimal radiation conditions and levels have been suggested for the equipment operation. The efficiencies of various TIS are compared. 230 refs.; 86 figs.; 4 tabs
