Radiation is all around us from a variety of natural and human-made sources every day. It is imperative in medicine and many other industries.
There’s a lot of misunderstanding around it and whether it is as dangerous as it is sometimes portrayed.
So, what exactly is radiation?
In physics, radiation is the emission of energy as electromagentic waves or moving subatomic particles. It travels through space or other media.
Rather than try to fully explain this here, we prefer to refer you to the best sources already available on other websites:
- The best answer we have seen to the question ‘What is radiation?’ is by the Australian Nuclear Science and Technology Organisation (ANTSO).
- Also, check out the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), the go-to source for information and news on radiation in Australia and around the world.
