Abstract:
A possibility to use the electron paramagnetic resonance (EPR) signal of neutron-irradiated lithium carbonate for thermal neutron fluence measurements has been investigated. The following aspects of the system have been studied: peak-to-peak signal amplitude as a function of thermal neutron fluence, signal fading, signal repeatability, sample batch homogeneity, and zero-fluence response of the probes. It has been concluded that lithium carbonate can be used as a material sensitive to thermal neutron fluences.
