Science behind the nuclear crisis in Japan

The unfortunate events at the nuclear power station in Fukushima, Japan, has resulted in plenty of science talk in the media.

Some of it has been well explained... Some of it has not.

At periodicvideos and Sixty Symbols we've posted some videos to help clarify a few points.

Most recent is this video about millisieverts - a unit I'd never even heard of!

We also posted some extra footage from this video at Test Tube.

And as I've previously blogged, here's The Professor on how reactors work and some of the things that can go wrong.

He also discusses some of the chemistry going on, such as why people take iodine and why there have been hydrogen explosions.


  1. A very clear and lucid explanation from the prof

  2. The reason for a football game is to advance the ball and score points into the other teams end zone. The football can be advanced by throwing it to another player which is known as a passing play or carrying it which is known as a running play.
