Did You Know? Bananas Are Radioactive, But Bigger Exposure Risks Surround You

Focus on home radon testing—not changing your diet—because background sources vastly outweigh any exposure from naturally radioactive foods.

LUBBOCK, Texas (RFD-TV) — Hearing “radioactivity in food” sounds scary, but the key is scale. However, there are much higher risks to farm families where we live and work: indoor radon. Compared with these ever-present sources, the contribution from foods is trivial.

Many foods contain trace amounts of naturally occurring radionuclides—most notably bananas and Brazil nuts—yet these levels are so low that they pose no health risk.

Radon is often the most significant routine exposure to radioactive material in many homes, particularly in basements and older farmhouses. You also receive radiation from cosmic rays (higher at elevation and when flying), natural radiation in soil and building materials, and the potassium that all human bodies carry.

Federal safeguards provide an additional layer of protection. FDA routinely monitors and enforces strict limits on foods, and the EPA provides clear guidance during any radiological event.

Do not confuse natural radioactivity with food irradiation—a safety step that kills bacteria and does not make food radioactive. Outside of an emergency, no special food actions are needed; the most practical step for rural households is to test for radon and follow local guidance if levels are high.

Farm-Level Takeaway: Focus on home radon testing—not changing diets—because background sources dwarf any exposure from naturally radioactive foods.
