what daily materials contain radioactive materials
Like kitty litter, bananas can trigger a radiation alert for authorities seeking nuclear material. I don't want you thinking bananas and Brazil nuts are the only radioactive foods out there. Basically, any food that is high in potassium naturally contains potassium-40 and is slightly, but significantly radioactive. This includes potatoes (radioactive french fries), carrots, lima beans and red meat.
You are exposed to radioactivity every day, often from the foods you eat and the products you use. Here is a look at some common everyday products and foods that are radioactive. Some of these objects may pose a health risk, but most of them are a harmless part of your everyday environment. In almost all cases, you get more exposure to radiation if you take a ride in a plane.
