Investigating the radiosensitivity effect of Dextran coated iron oxide nanoparticles on HeLa cell line irradiated with 6 and 12 MeV electron beams.

Background and objective: Nowadays cancer is one of the most important causes of morbidity and mortality in the world. In recent decades cancer treatments have been advanced significantly. In radiotherapy, the ideal aim is delivering lethal dose of radiation to the tumor cells so that healthy tissue around tumor, have the least amount of exposure at the same time. One way to increase the dose in the tumor cells is using high atomic number nanoparticles as radiation sensitizers in these cells.
