The Problem of Radioactivity exits in the atmosphere soil and water since the earth was created. Over 60 radionuclides (radioactive elements) can be found in nature, and they can be placed in three general categories:1. Primordial - from before the creation of the Earth. 2. Cosmogenic - formed as a result of cosmic ray interactions. 3. Human produced - enhanced or formed due to human actions (minor amounts compared to natural)
Inexorably some of this gets into the food we eat. Generally all foods are technically all food is slightly radioactive because all food and other organic materials contain carbon, which naturally exists as a mixture of isotopes, including radioactive carbon-14.When we use radioactive foods or radioactive material it decay some of radiations which will hit the cells in our body and perhaps increase the chances of cancer. But radioactive material does not always deadly or dangerous. Human being use radioactive material since the binging of human history. It is the level of radioactive material which is the subject of worry. The Plant and animal could become surface and tissue radioactively contaminated when they inhale radiologically contaminated nutrients. surface contamination can be largely removed by washing but tissue contamination cannot be so removed by washing and it will be reduced over the time. People become radioactively contaminated when they use radioactively contaminated food stuff. Common foods that are naturally radioactive include potatoes, bananas, sunflower seeds, many nuts, and kidney beans, among others.  Among these, Brazil nuts are the world most radioactive food. Every food has some small amount of radioactivity in it. The common radioactive atom present in food are potassium 40 (40K), radium 226 (226Ra) and uranium 238 (238U).
