Short answer. Thailand publishes no distribution of potassium iodide (KI) to households, no pre-distribution zones and no sale rules. The Office of Atoms for Peace (OAP) says its memorandum of understanding with the Ministry of Public Health on medical response to nuclear and radiological emergencies includes keeping a stockpile of medicines and potassium iodide to protect the thyroid 1.
Is potassium iodide distributed in Thailand?
No household distribution is published. The only official arrangement found is a state stockpile held under the OAP and Ministry of Public Health agreement 1. In OAP's words: "สำรองคลังยาและสารโพแทสเซียมไอโอไดด์ (KI): จัดเตรียมคลังยาสำคัญ เช่น โพแทสเซียมไอโอไดด์ เพื่อปกป้องต่อมไทรอยด์" (stockpile of medicines and potassium iodide: prepare key medicine stocks such as potassium iodide to protect the thyroid) 1.

Who plans for a nuclear or radiological emergency?
OAP is the nuclear and radiation regulator. It works with the Ministry of Public Health on medical response 1 and has run work to strengthen provincial capacity to respond to nuclear and radiological incidents 2. In an emergency, follow the instructions of the authorities; see alerts for how they reach you.
Should I take iodine on my own?
Thailand publishes no instruction for households on taking potassium iodide. Take it only if the authorities tell you to. Our guide explains what it does, its limits and its contraindications, with its own sources: /guides/potassium-iodide. Since Thailand publishes no sale rules, ask a pharmacist or doctor before buying any.
What else protects against fallout?
Sheltering indoors and limiting exposure matter more than tablets. See /guides/fallout-7-10-rule, /guides/protection-factor, /guides/radiation-decontamination and /guides/nuclear-plant-zones.
