Potassium Iodide Radiation Tablets Market Outlook 2025–2031

The global Potassium Iodide Radiation Tablets Market size is estimated at US$ 245 million in 2025 and is projected to reach approximately US$ 372 million by 2031, growing at a CAGR of 6.9% during 2025–2031.
Growing concerns around nuclear accidents, radioactive exposure risks, and government-led emergency preparedness initiatives are steadily strengthening demand for potassium iodide radiation tablets worldwide.

Market Background and Historical Performance

Potassium iodide radiation tablets are medically approved prophylactic drugs used to protect the thyroid gland from radioactive iodine exposure during nuclear emergencies. Over the past five years, demand has shown moderate but consistent growth due to increased geopolitical tensions, expansion of nuclear power generation, and heightened public health awareness.

Between 2020 and 2024, the market grew from an estimated US$ 198 million to US$ 230 million, registering a historical CAGR of around 3.8%. The COVID-19 pandemic period initially disrupted pharmaceutical supply chains; however, post-2022 recovery and renewed nuclear safety discussions accelerated procurement by governments and healthcare agencies.

What Is Driving the Potassium Iodide Radiation Tablets Market?

Potassium iodide (KI) tablets work by saturating the thyroid gland with stable iodine, thereby preventing absorption of radioactive iodine isotopes. This makes them a critical component of nuclear emergency stockpiles across multiple countries.

The primary growth driver is the expansion of nuclear power infrastructure, especially in Asia-Pacific and Eastern Europe. Additionally, rising concerns over nuclear weapon testing, radiological terrorism, and industrial radiation leaks are prompting governments to maintain adequate KI tablet reserves.

Public awareness campaigns and WHO-recommended emergency preparedness protocols are also supporting wider distribution beyond hospitals, extending to schools, military units, and disaster-response agencies.
