Yes, radiation can kill. So can water. There is a difference between a hug and a bone splintering embrace, and too many of these articles are using fear and ignorance to equate the former with the later.
Yes, Fukushima was a bad accident with devistating consequences for the people who lived in the immediate area. Most of the damage was financial and cultural, but there are almost certain to be some long term health effects as well. I suggest you watch the documentary: "Children of the Tsunami" for a heartbreaking look at how this impacted the kids in this area. I will link to it below.
In any case, that's the impact, and it is bad enough to justify any anti-nuclear position you might like. It's not helpful to try and stretch it beyond this, and the attempts to do so using fictional nightmare scenarios and pretend science only turn people off.
More, and this needs to be said, Fukushima was only one aspect of a much more significant disaster. The Tohoku Quake and Tsunami damaged or destroyed over 1.2 MILLION significant buildings, killed at least 19,000 people, and caused close to a Trillion USD in direct and indirect damages. It literally wiped hundreds of cities and towns and villages off the map, and even when the people survived there is nothing left there to return to. The entire eastern coast of the nation was wiped clean.
This is the tragedy being swept aside and dismissed to focus attention on these fictions. Watch all of this video. These are children watching everything they know and love destroyed -- including in many cases their families.
No. Actually WATCH it. It's still gone. Last year this is what it still looked like:
