In this study, a physical evaluation of internal radiation exposure in children was conducted using nuclear medi cine test(Renal DTPA Dynamic Study) to simulate the distribution and effects of the radiation throughout the tracer ki netics over time. Monte Carlo simulations were performed to determine the internal medical radiation exposure during the tests and to provide basic data for medical radiation exposure management. Specifically, dose variability based on changes in the tracer kinetic was simulated over time. The internal exposure to the target organ (kidney) and other surrounding organs was then quantitatively evaluated and presented. When kidney function was normal, the dose to the target or gan(kidney) was approximately 0.433 mGy/mCi, and the dose to the surrounding organs was approximately 0.138?0.266 mGy/mCi. When kidney function was abnormal, the dose to the surrounding organs was 0.228?0.419 mGy/mCi. This study achieved detailed radiation dose measurements in highly sensitive pediatric patients and enabled the prediction of radiation doses according to kidney function values. The proposed method can provide useful insights for medical radia tion exposure management, which is particularly important and necessary for pediatric patients.
