Video: Radiation is all around us and too much of radiation is a bad thing so... are we all just screwed from all the radio waves and microwaves and ultraviolet radiation and rainbows and X-rays and radon and nuclear radiation in the world? Not exactly. Ted-Ed explains in the video animation below how not all radiation is created equal (we just have to protect ourselves from the ionising radiation) and details how much radiation is actually damaging for us (four Sieverts!).

A recent edition of the ABC’s Catalyst programme looked into the issues of the health effects of electromagnetic (EM) radiation. The episode "takes a closer look at the link between mobile phones and brain cancer, and explores whether our wireless devices could be putting our health at risk".

Dr Devra Davis stated on the show, "With respect to mobile phones and brain cancer, the reality is every single well-designed study ever conducted finds an increased risk of brain cancer with the heaviest users, and the range of the risk is between 50 per cent to eightfold. That's a fact."

Experts have now spoken out about the program's findings.

The accident at the Chernobyl Nuclear Power Plant in 1986 had a devastating impact on the local population and forced 116,000 people to permanently leave their homes. But now researchers have discovered that, while the people may not have returned, the contaminated area of Belarus is teeming with wild animals, including elk, wild boar, deer and wolves. Perhaps surprisingly, many of these numbers seem to be on the rise and some of them are higher than in uncontaminated areas.

Radiation tends to strike fear in the hearts of the general populace, particularly the ionizing variety produced by X-rays and radioactive elements. But most have no idea what actual radiation looks like. Now a French organisation called CloudyLabs has found a way to let us see the process in action using a simple cloud chamber.

People are terrified that they're being exposed to radiation all the time, whether from distant nuclear accident or the mobile devices snuggled against their heads. Generally, they are wrong. Here are the most radioactive objects in the world around you, and the truth about which ones cause health problems.

A picture of some deformed plant sex organs is alarming people all over the internet this week. The photo, taken by Twitter user @san_kaido, shows a bunch of daisies that look like conjoined twins. The accompanying tweet describes their twisted, ribbonlike appearance, and reports a radiation reading for the spot.
