In astronomy the main source of information about celestial bodies and other objects is the visible light or more generally electromagnetic radiation From Wikipedia It also is important for the atmosphere of Earth so youll meet it if you are going into Earth atmosphere science. The US Environmental Protection Agency EPA is responsible for advising the government on radiation hazards and regulating certain sources of radioactivity in the environment This booklet provides basic facts about radiation science as well as inform of Mars.
