Beta Decay of Iodine-131

¹³¹I → ¹³¹Xe + e⁻ + ν̄_e + γ

Ikhtisar

Iodine-131 beta decays to xenon-131 with a half-life of 8.02 days, also emitting gamma radiation. I-131 concentrates in the thyroid gland due to the thyroid's uptake of iodine. This makes it both a medical tool (diagnostic and therapeutic) and a health hazard in nuclear accidents.

Contoh Sehari-hari

After the Chernobyl and Fukushima accidents, potassium iodide tablets were distributed to block I-131 uptake by saturating the thyroid with stable iodine.

Pentingnya dalam Industri

I-131 is used to treat hyperthyroidism and thyroid cancer (radioiodine therapy), and in diagnostic thyroid scans.
