The gamma (γ) induced modifications in the synthesized Pani‐Ag/PVA nanocomposite (NCP) thermal and optical characteristics have been depicted. The induced effect was investigated applying X‐ray diffraction, differential scanning calorimetry, and UV‐spectroscopy. Further, the color intensity (ΔE) of the irradiated NCP and blank has been estimated. The γ radiation decreases the optical band gap value from 2.65 to 1.54 eV owing to the randomly amorphous dominance in the irradiated NCP. Moreover, γ radiation induced noticeable defects generation, splitting the crystals, leading to depressed melting temperature.
