Fermat's two squares theorem

The feasibility of Durolon as a thermal neutron dosimeter was studied. As experimentally determined the proposed methodology covers a wide range of doses, from 0.1 mSv<D<150 mSv, and can be used either for personal dosimetry or for area monitoring. Its insensitivity to visible light, beta and gamma radiations, makes the method attractive in order to evaluate neutron doses even in mixed radiation fields.
