Transcript of Atoms in Radioactivity

Some rocks contain radioactive substances that produce a radioactive gas called radon. The pie chart shows the average contribution of these different sources to our natural background radiation.
There is little we can do about natural background radiation. After all, we cannot stop eating, drinking or breathing to avoid it! However, human activity has added to background radiation by creating and using artificial sources of radiation. These include radioactive waste from nuclear power stations, radioactive fallout from nuclear weapons testing and medical X-rays.
