Why does banana have radiation? Several sources point out that the banana equivalent dose is a flawed concept because consuming a banana does not increase one's exposure to radioactive potassium. We are notentirely protected, but our knowledge ofradioactive substances is critical, as they have found their way into a wide range of medical research and treatments. There is a greater, but still insignificant, exposure to radioactivity by sleeping next to someone. Energy is released in the form of radiation as the atom tries to reach stability, or become non-radioactive. So are our bodies also radioactive? The high amount of saturated fat in red meatpresents more of a health risk than the radiation level. Cosmic radiation from the Sun and outer space, radiation from rocks and soil, as well as radioactivity in the air we breathe and in our food and water, are all sources of natural radiation. Radiation is not always dangerous it depends on the type, the strength, and how long you are exposed to it. The words radiation and radioactivity are often used interchangeably. This oversight extends to ensuring the safety of these imported products as well. That is absolutely true. Bananas | The Nutrition Source | Harvard T.H.
