Abstract

A NEW medium-high dose label dosimeter film based on using gamma radiation in executing reduction for Nickel ions to Nickel-metal inside the host polymer matrix, poly (vinyl alcohol)/ poly (vinyl pyrrolidone) is prepared. The results of absorption spectra investigation reveal that the film has surface plasmon resonance (SPR) of Nickel nanoparticles (NiNPs) correlated with irradiation doses. Different techniques were used to ensure the formation of NiNPs such as XRD pattern and TEM. The size of the Ni-nanoparticles was 40 to 50 nm. Studying the dosimetric behavior for the composite film reveals a response curve ranging from 20-350 kGy covering the medium and the high dose applications such as cross-linking of polymers, polymer modifications, and others. This film can be used as a label in the chosen range as its color turns from faint green to pale gray by irradiation. PVA/PVP/Ni nanocomposites films have also excellent post stability in different environmental conditions.
