The exposure to ionizing radiation is significantly more harmful to paediatric patients than adults due to their low body size, increased levels of cell division, and a higher lifespan. The use of CT imaging is invaluable clinically, but the medical radiation amount in children makes radiation-related health effects a long-term issue of concern. Since children can absorb proportionately larger doses of organ dose during the same CT conditions as adult patients, it is important that we learn how CT parameters affect dose to enable safe paediatric imaging. This study is significant in enhancing understanding of radiation–matter interaction and dose deposition mechanisms in paediatric computed tomography, which are core concepts in applied physics. By analysing how X-ray photons interact with different tissues under varying scan parameters, the project reinforces fundamental physics principles including photon attenuation, scattering processes, and energy transfer in heterogeneous media.
