Uncontrolled cell development is a hallmark of cancer, a leading cause of death globally. Optimal cancer treatment necessitates the use of multiple methods, including surgery, chemotherapy, and radiation treatment. High-energy radiation in radiotherapy eliminates cancer cells by causing irreparable damage to their DNA (deoxyribonucleic acid). The radiation dose is delivered via a teletherapy unit. Dosimetric quality assurance tests are conducted to ensure accurate and safe radiation delivery. Guidelines for dosimetry are provided by AAPM TG 51 and IAEA TRS 398. We followed the dosimetry protocol of the International Atomic Energy Agency (IAEA) TRS 398. Dosimetry data were collected and evaluated for a period of nine years, beginning in 2014 and ending in 2022. The analysis of dosimetry data from 2014 to 2022 showed that the difference between the measured and calculated dose rate is 1.904 ± 1.41, which is below the IAEA guidelines, i.e., ±2%. The results suggest that dosimetry was in accordance with international protocols. It also reflects that radiation dosimetry is well carried out at BINOR cancer hospital.
