Can food have radiation?
The FDA has approved food irradiation for a number of foods. Irradiation can be used on herbs and spices, fresh fruits and vegetables, wheat, flour, pork, poultry and other meat, and some seafood. The FDA requires that irradiated food labels contain both a logo and a statement that the food has been irradiated.
Which foods contain radiation?
Top 10: Which are the most radioactive foods?

How much radiation is safe in food?
Radioactive material in food is measured in becquerels, or Bq. The limit for iodine-131 is 55 Bq per kilogram for infant food and 300 Bq per kilogram for other foods regulated by the FDA. For meat and poultry, which are regulated by the Department of Agriculture, the limit is 55 Bq per kilogram.
How do foods become radioactive?
During irradiation, food is exposed to electron beams, X-rays or gamma rays. The effect is similar to other preservation methods, such as pasteurisation or cooking. The appearance and texture of the food changes less during irradiation than other preservation methods.
Why is food treated with radiation?
Food irradiation (the application of ionizing radiation to food) is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects. Like pasteurizing milk and canning fruits and vegetables, irradiation can make food safer for the consumer.
Why does irradiating food make it safe to eat?
Irradiation makes meat and poultry safer by reducing the numbers of harmful bacteria and parasites. Food irradiation does not make foods radioactive. The radiant energy passes through the food. Nutrient losses caused by irradiation are less than or about the same as losses caused by cooking and freezing.
What fruit has the most radiation?
Bananas
Bananas. You probably already knew that bananas are loaded with potassium. But bananas also happen to be one of the most radioactive foods because they contain the isotope potassium-40. Thanks to this isotope, everyone’s favorite yellow fruit emits a tiny amount of radiation.
What vegetable has the most radiation?
10 Common Radioactive Foods
| Food | Radioisotope | Radiation Type |
|---|---|---|
| Carrots | Potassium-40 Radon-226 | Beta particles Alpha particles Gamma radiation |
| Potatoes | Potassium-40 Radon-226 | Beta particles Alpha particles Gamma radiation |
| Low-sodium salt (NaCl + KCl) | Potassium-40 | Beta particles |
| Red meat | Potassium-40 | Beta particles |
Which fruit is most radioactive?
What foods reduce radiation?
Cruciferous vegetables (arugula, Bok choy, broccoli, Brussels sprouts, cabbage, cauliflower, collards, horseradish, kale, kohlrabi, mustards greens, radishes, turnips, wasabi and watercress) provide us with antioxidants, indoles and sulfur.
What is the most radioactive food we eat?
Brazil nuts are the most radioactive everyday food. However, large quantities of Brazil nuts, lima beans, and bananas all can set off radiation detectors when they pass through shipping. The radiation dose from eating one banana is calculated at 10−7 Sievert or 0.1 microSieverts.
