In the midst of all that's going on in Japan, we managed to sit one of our (extremely busy) nuclear issue experts down and ask him a few of the top questions people have been asking. 

If you don't find the answer you're looking for here, try our extensive Q and A briefing, or our briefing on radiation safety/effects.  As always, we'll keep adding updates to our main page, and Twitter account.

Here's what Jan had to say:

What are the risks to neighbouring countries?

How does Fukushima compare to Chernobyl?

How much radiation is dangerous?

What is/was the worst case scenario?

Are new reactors any safer?

What does this mean for the nuclear industry world-wide?

What next for Fukushima?
