The effective doses received by the general population from the natural radioactivity in the city of São Paulo, Brazil, were assessed from 2007 to 2013, as, apart from the variation from place to place, the background gamma levels in air are not constant...

Ultraviolet (UV) radiation has affected life at least since the first life forms moved out of the seas and crawled onto the land. Therefore, one might assume that evolution has adapted to natural UV radiation. However, evolution is mostly concerned with ...
