Radiobiology and Microdosimetry


Naim completed his B.Sc. degree in Physiology at McGill University and will pursue a M.Sc. in Biological and Biomedical Engineering under the supervision of Dr. Shirin Abbasinejad Enger. Naim joined Dr. Enger’s Lab in January 2021 and has since been working on Hela adenocarcinoma cell studies to compare the relative biological effectiveness of different radiation modalities.

Relative Biological Effectiveness of Different Radiation Qualities for Hela Adenocarcinoma Cells

There are many various types of radiation qualities that are used in radiotherapy treatment of cancer. However, despite the same physical dose of radiation from different radiation qualities produces varying amounts of biological damage. Therefore, it is of importance to determine the amount of biological damage a radiation quality induces in different cancer cell lines. 

Naim is performing cell studies on Hela adenocarcinoma cells to determine the difference in relative biological effectiveness of Iridium-192 brachytherapy source, Xoft electronic brachytherapy source and MV photons compared with 225 kVp X-rays.
