WebPurpose: Renal function and effective half-life (t 1/2,eff) of I-131 have not been fully elucidated in patients undergoing radioiodine therapy (RAIT) for differentiated thyroid cancer (DTC).Aim of the present analysis was to evaluate the potential of cystatin C-based estimated glomerular filtration rate (eGFR CysC) in comparison to conventional … WebAug 13, 2024 · This continues until the entire sample of iodine-131. has completely decayed (see figure below). Figure 10.3. 1: The half-life of iodine-131 is eight days. Half of a given sample of iodine-131 decays after each eight-day time period elapses. Half-lives have a very wide range, from billions of years to fractions of a second.

WebHalf-life: 8.06 days. Mode of decay: Beta particles and gamma radiation Chemical properties: I-131 can change directly from a solid into a gas, skipping the liquid phase, in a process called sublimation. I-131 dissolves easily in water or alcohol. I-131 readily combines with other elements and does not stay in its pure form once released into the environment.
