Abstract
Described is herein a radiation measuring apparatus in which a detected pulse signal having a wave height value proportional to energy of radiation is transmitted through an optical fiber and a detected pulse signal received from the optical fiber is supplied to an external apparatus. Even if the transmission loss of the optical fiber is subjected to change with passage of time, a monitor pulse signal having a polarity reverse to that of a detected pulse signal is overlapped on the detected pulse signal lest the wave height of the detected pulse signal be not varied on the transmitting side, and a wave height value of a monitor pulse signal passed through the optical fiber is detected to compensate the wave height of the received detected pulse signal using the detected value.
