| Background: Usage of low radiation is indispensable, hence accurate measurement became inevitable for radiation practitioners and patients. The current study presents the synthesis and characterization of polyvinyl alcohol doped with Thymol Blue and Cuprous Oxide (PVA/TB/Cu2O) as nanocomposite films for low radiation dosimetry. Method: films prepared under controlled parameters (PVA 5%, temperature 80 ⁰C, 0.01 g of TB and 0.2 g of Cu2O). The films were irradiated with X-ray (0, 2, 4, 6, 8, 10 mGy) and evaluated using UV-spectroscope, XRD, and FTIR. Results: UV- spectroscope for (PVA/TB) films showed absorbance peaks at l = 435, 326 and 279 nm, which de-creased as the radiation dose increased. (PVA/TB/Cu2O) films showed absorbance bands at l = 265 & 370 nm, which increased as the radiation dose increased. XRD for (PVA/TB) reveals the crystallinity of PVA at 2 thetas = 200 which increased by 55% at 10 mGy. The PVA/TB/Cu2O composite films present a prominent peak at 2 Thetas = 350, which increases following the radiation doses. The FTIR spectroscope showed chemical bonds (CH, C-O, C-O-C, CH2, C-OH, C=O, C≡N, and OH) intensities that degraded as the radiation dose increased. Conclusion: the composite of PVA/TB ± Cu2O is utilizable for radiometer based on optical and chemical changes. | ||||
