At the present work nano SiO2 has been irradiated by 2x1013 cm-2s-1 neutron flux at different times up to 20 hours. It has been comparatively analyzed the frequency dependencies of real and imaginary parts of dielectric constant of the nanomaterial exposed to neutron flux influence and initial state. From analysis results it has been revealed that the permittivity of nano SiO2 increases in general tendency with influence of neutron flux. The mutual dependence of the real and imaginary parts of dielectric constant of nano SiO2 particles has been reviewed. From the cases similar to Cole-Cole diagrams existing in the dependencies it has been revealed that the value of the relaxation period is compatible with polarization of the nano particles.
