The nature of electron-induced changes in the electrical properties of Zener diodes and their application to a Zener diode dosimeter are presented. A standard Zener diode is used as a small size (0.15 x 0.4 x 0.4 mm), high-level dose detector. The irradiated dose can be estimated by a shift of the breakdown voltage of the Zener diode. The distinct advantages of its small size and superior resistance to radiation damage enable us to measure the cross-sectional profile of the high-intensity electron beam from a linac with high spatial resolution of about 0.4 mm.
