Synthesis of Complexed Grafted Low Density Polyethylene Films and Its Applicability in Nuclear Medicine as Radiation Shielding Against Technetium-99 m

Abstract

Low density polyethylene films were grafted by poly (acrylic acid). The effects of dose, monomer concentration, solvent, inhibitor and thickness of films were investigated. Adsorption capacities of grafted films of Pb 2þ and Cd 2þ reached up to 20 and 13 (mg/g), respectively. The complexed grafted films in protection of workers against technetium-99 m radiation dangers were investigated. The effects of grafting percentage, thickness and adsorption capacity of ions on shielding efficiency were studied. The transmission intensity of complexed grafted films decreased gradually until arrived almost 0%. The protection efficiency of complexed grafted films is higher than grafted and virgin films, respectively.

Polymeric composite materials for radiation shielding: a review

“…Besides, polymers proved their performance and applicability in nuclear medicine as radiation shielding against Technetium-99m, where complexed grafted low-density polyethylene films revealed that the protection efficiency of complexed grafted films was higher than in grafted and virgin films (Awadallah-F and Antar 2014). Also, most frequently used polymers such as POM-polyoxymethylene, PAN-polyacrylonitrile, NR-natural rubber, PEApolymethyl acrylate, PPM-poly-phenyl-methacrylate, PET-polyethylene terephthalate (Bhosale et al 2017) and polyamide (nylon 6) (PA-6), polyacrylonitrile (PAN), polyvinylidene chloride (PVDC), polyaniline (PANI), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polypyrrole (PPy), and polytetrafluoroethylene (PTFE) (Kaçal et al 2019) were studied in terms of their gamma radiation attenuation.…”

Silica-based mesoporous ion-imprinted fluorescent sensors for the detection of Pb2+ in aqueous environments

“…Lead metal (Pb) has good ductility and corrosion resistance and is widely used in storage batteries, cable sheathing, paints and pigments, machinery manufacturing, radiation protection, and other industries [1][2][3]. Pb 2+ is a neurotoxin and is a nonessential metal in the ecosystem.…”
