Abstract

In this paper we report the results of the electron spin resonance (ESR) study of the radiation-inducedsignal of watch glasses exposed to neutrons. This work extends the series of analyses of the responseof watch glasses to various radiation beams which our research group is carrying out for possible applicationsin retrospective dosimetry. We have considered fluences up to about 3x1011 cm 2. We evaluatedthe signal fading and we found that in the first hours after exposure the signal rapidly decreases.After about 1000 h, it decreases much more slowly. The signal was reduced by about 25% in about5 months. The radiation induced signal is found to be linearly dependent on neutron fluence and an estimateof the lowest detectable fluence is provided.
