WebIodine- 131 has a half-life of 8.05 days. If you begin with 25.0 mg of radioactive 131I, what mass will remain after 32.2 days (about a month; nuclear decay is a first order process)? Question: Iodine-131 is used in the form of sodium iodide to treat cancer of the thyroid. Iodine- 131 has a half-life of 8.05 days. Web7 de may. de 2024 · As the chain yield of Iodine-131 is considerably high and the radioiodine isotopes with mass higher than 131 are short-lived, this radioisotope is easily obtained in pure form.
