Abstract

This paper reports on the use of rare earth doped optical fibers for the detection of low dose electron beams in radiotherapy applications. Neodymium and cerium doped singlemode fibers have been irradiated with 10 MeV electron beams and the losses induced by the radiation have been measured in the wavelength range 1200 - 1600 nm, the attenuation has a linear dependence with the applied dose and its order of magnitude is 0.001 dB per meter of fiber and cGy.
