Modelling the Accumulation of Radiation Dose over Time from a Decaying Radioactive Source and its Implication for Health and Safety.
Abstract
This study investigates the accumulation of radiation dose over time in the presence of radioactive decay, analyzing the impact of half-life, initial dose rate, and decay constant on exposure levels. Using an analytical modeling approach, the research explores both short-term and long-term dose accumulation, highlighting key differences in radiation risk profiles. The findings indicate that sources with shorter half-lives cause rapid initial dose accumulation but stabilize quickly, whereas longer half-life sources contribute to prolonged radiation exposure. Sensitivity analysis reveals that variations in the initial dose rate significantly affect long-term exposure levels, while decay constants influence the rate at which radiation stabilizes. The study underscores the importance of managing these factors to minimize radiation risks posesand improve safety protocols in occupational and environmental settings. These insights are crucial for optimizing radiation protection strategies, ensuring controlled exposure, and mitigating long-term health effects.
