Simulation of 131I emergency emission. Processes of dose formation

Abstract

Kinetics of 131I and dose formation in tissues and organs of laboratory Wistar rats in a simulation of long entry of the isotope were studied. The function of weight of the thyroid gland changes due to accumulation of absorbed dose in the body was optimized. Maximum activity of the initial ingestion of the isotope in the body, above which the thyroid tissue loses its ability to retain iodine was substantiated. Residual thyroid tissue mass after radiation damage was estimated. Features of the processes of dose formation in other tissues and organs were described.
