VERDICT: true
Confidence: 99%
Evidence FOR:
- Bananas contain potassium, including a tiny proportion of the naturally radioactive isotope potassium-40.
- The U.S. EPA estimates that eating one banana delivers about 0.1 microsievert (0.01 millirem) of radiation.
- A typical banana has an activity of roughly 15 becquerels, meaning radioactive decays occur within it.
- Multiple scientific and educational sources explicitly confirm that bananas are slightly radioactive.
Evidence AGAINST:
- “Radioactive” can sound dangerously radioactive, but the amount is extremely small and does not pose a meaningful health risk.
- Potassium is regulated by the body, so potassium-40 from bananas does not simply accumulate with continued consumption.
- The “banana equivalent dose” is only an informal educational comparison and can oversimplify actual radiation exposure.
