On the γ-Radiation Dosimetry using a Layered Metamaterial Structure Comprising FTO and Blue Glass

A layered metamaterial comprising periodic blue glass and FTO mediums was investigated for gamma (γ) radiation dosimetry. The device acts on the principle of absorption of the incidence radiation with sharp resonance absorption peaks which undergo shifts in the presence of γ-radiation. The more the radiation dose is, the more shift happens in the resonance absorption spectrum - the feature that can be exploited in the design of polarization insensitive γ-radiation dosimetry device.
