Abstract
In a radiation detecting apparatus having its radiation receiving section composed of two-dimensional or one-dimentional array of radiation sensors, the whole electronic circuit is classified into a temperature-sensitive circuit portion and a temperature-insensitive circuit portion for keeping at least the temperature-sensitive circuit portion at a substantially constant temperature also during the period in which the apparatus is kept standing for detecting a radiation image. For the purpose, at least the above temperature-sensitive circuit portion is kept energized even when a radiation image is not detected; kept warmed by a heating element energized only when a radiation image is not detected, made to get in touch with a heat sink intermittently; or blown at least intermittently by a blower or blowers.
