Food may contain different types and amounts of naturally-occurring radioactive materials. For example, a small fraction (0.012%) of potassium in foods is radioactive. Additionally, naturally-occurring radioactive materials in the soil can transfer to crops, and fish and shellfish can take up radioactivity from water or sediments. Generally, food in the home contains too little radioactivity to be detected and does not pose a significant health risk.
