    What is Radiation?

    To be able to talk about the levels, effects and risks of radiation exposure, we first need to address some basics of radiation science. Both radioactivity and the radiation it produces existed on Earth long before life emerged. In fact, they have been present in space since the beginning of the universe and radioactive material was part of the Earth at its very formation. But humanity first discovered this elemental, universal phenomenon only in the last years of the nineteenth century and we are still learning new ways of using it.
