PURPOSE:To provide a radiation dose measuring apparatus which enables a correct radiation dose to be attained by correcting mistake in counting inevitably generated at the time when a plurality of photons are made incident with in a close time by a simple linear correction as caused. CONSTITUTION:This apparatus is provided with a switching element 11 to switch an output of a radiation detector 1 to either of the states in which it is introduced into a charge voltage conversion circuit 2 and in which it is not, a discharging means 12 to discharge an electric charge accumulated in the charge voltage conversion circuit 2, a control circuit 10 to operate the switching element 11 and the discharging means 12 at a fixed cycle respectively synchronizing an external clock. Thus, the dead time of a system is always kept constant.
