Comparison of dose enhancement effect of iron oxide nanoparticles on HeLa cancerous cell line exposed to high-energy electron and photon beams

Autor: Karim khoshgard, Hossein mafakheri, Ahmad Mohammadbeigi, Maryam hazbavi, Masoud Rezaei

Publikováno v: Majallah-i Dānishkadah-i ̒ulūm-i Pizishkī-i Niyshābūr, Vol 5, Iss 3, Pp 37-46 (2017)

Introduction and aims: The aim of radiotherapy is delivering lethal dose of radiation to tumor cells while adjacent healthy tissues would have the least amount of irradiation. One way to increase the dose in the tumor cells is using high atomic numbe
