Fukushima blew plutonium laced fuel all over eastern Japan. The reactor cores melted through the containment vessels. A natural mountain stream up the mountain from the plant site is pushing a constant stream of water through the facility. Radiactive material is constantly being washed into the ocean. Levels of radiation just outside the Unit #3 are 20 Sieverts per hour. A 5 minute exposure is lethal to a human. The robots sent in to investigate are failing quickly after entering the building as level are MUCH higher inside. A nuclear weapon is a very clean event compared to a nuclear power plant meltdown.

Given the choice, I would prefer to try to escape a nuclear power plant accident over getting nuked by a bomb. IIRC civilians close to ground zero in Hiroshima were instantly incinerated, and those a few miles away suffered longer agony with peeled of burned skins and other horrible long term effects of radiation exposure. I am not certain so many people near Fukushima suffered something similar.

When I worked at the lab where first sustained nuclear reaction in the world took place, there were reports of radio-active test specimens lying around the 5 square mile laboratory site during the years immediately following the initial successful chain reaction.
