Dosimetric investigations on radiation-induced Ag nanoparticles in a gel dosimeter

Radiation-induced Ag degrees nanoparticles (NPs) in silver nitrate gel dosimeter incorporating various components was investigated in the dose range of 0-100 Gy. The gel responses were analyzed at 450 nm, a Surface Plasmon Resonance band of AgNPs. The radiation sensitivity of the gel increases with increasing Ag+ concentrations and isopropanol, % and decreases with boosting gelatin content and H+ ions. This gel features good water equivalency in energies from 0.3 to 20 MeV and has potential applications in the dose range of 5-100 Gy based on the selected compositions. Thus, it can cover blood irradiation and radiotherapy dosimetry applications.

Automated summary

The study found that the radiation sensitivity of the gel increases with higher concentrations of Ag+ and isopropanol, while decreases with boosting gelatin content and H+ ions. The gel exhibits good water equivalency in energies ranging from 0.3 to 20 MeV and is potentially suitable for doses between 5-100 Gy.
