# FALSE: Microwaving food makes it radioactive.

> The claim conflicts with basic radiation physics and public regulator guidance. Microwave ovens use non-ionizing radiation to heat food; they do not create radioactivity in the food.

## Claim
Microwaving food makes it radioactive.

## Verdict
- Label: FALSE
- Source match: Weak
- Confidence: High
- Score: 5
- Meaning: Microwaves heat food. They do not turn food radioactive.

## Copy-Ready Comeback
FactPage check: FALSE. — microwaving food heats it, but does not make it radioactive.

## Bottom Line
The claim conflicts with basic radiation physics and public regulator guidance. Microwave ovens use non-ionizing radiation to heat food; they do not create radioactivity in the food.

## Evidence Lines
1. Non-ionizing energy cannot make food radioactive - Microwaves are non-ionizing electromagnetic radiation. They do not carry enough energy to change atomic nuclei or create radioactive material in food.
2. The effect is heating, not contamination - In a microwave oven, water, fats, and sugars absorb microwave energy and convert it into heat. The food does not keep emitting radiation after the oven stops.
3. Real microwave risks are different - Regulators warn about burns, uneven heating, and leakage from damaged ovens. Those are safety issues, but they are not evidence that microwaved food becomes radioactive.
