Photon irradiation response of photonic crystal fibres and flat fibres at radiation therapy doses

Radiation effects of photon irradiation in pure Photonic Crystal Fibres (PCF) and Flat fibres (FF) are still much less investigated in thermoluminescense dosimetry (TLD). We have reported the TL response of PCF and FF subjected to 6MV photon irradiation. The proposed dosimeter shows good linearity a...

Description
Summary:Radiation effects of photon irradiation in pure Photonic Crystal Fibres (PCF) and Flat fibres (FF) are still much less investigated in thermoluminescense dosimetry (TLD). We have reported the TL response of PCF and FF subjected to 6MV photon irradiation. The proposed dosimeter shows good linearity at doses ranging from 1 to 4Gy. The small size of these detectors points to its use as a dosimeter at megavoltage energies, where better tissue-equivalence and the Bragg–Gray cavity theory prevails. •First study about radiation effects of photon irradiation in pure Photonic Crystal Fibres (PCF) and Flat fibres (FF).•PCF and FF. have been found to have good dose linearity (up to 4Gy).•The value of Zeff obtained is in the range of 10.3–11.3 and 11.3–11.8 for PCF and FF respectively.
