It is the continual leakage that the naysayers refuse to consider. With a bomb, it's a one time thing and X days to half life. With this, it's 24/7/365 for nearly 3 years and no end in sight.

You missed a few inconvenient facts:
1) The nuclear testing occurred over a period of twelve years. So there was a good bit of replenishment going on...
2) The half-life of iodine-131 is almost exactly eight days. There is extremely little new I-131 being produced at Fukushima, so it is a non-concern at this point - making the frenzy surrounding potassium pill sales very amusing! Ignorance, the gift that keeps on giving. :-)
3) Caesium-137 has a half life of just over 30 years. So, even 30 years after the testing, fully half of the Cs-137 fallout was still in the ocean. Today, around one-quarter of it is still in the ocean (although like much of the Fukushima waste, harmlessly sitting on the bottom in deep water).
I hope this cleared a few things up for you.
