Okay, let's talk about the daisies first. What you see here is a phenomenon called 'stem fasciation'. It has been found in hundreds of plant species and is a normal mutation. It occurs sporadically and is not hereditably. These daisies have been found in Nasushiobara, which is 100km away from Fukoshima, where, according to experts, the radiation level is unproblematic. The likelihood that particles from the nuclear plant are responsible is low.
About the rest. Hmmm...for me this sounds like you've fallen victim of astroturfing. I don't want to go into detail here, but the fact alone that ²³³uranium is one of the waste products is a big no no for me as it can be used for nuclear weapons. A byproduct is ²³²uranium, which emits gamma radiation. The technology is still at an immature stage, so risks, costs and consequences can't be predicted. There is an interesting survey study commissioned by the Norwegian government, which didn't lose its significance, although it's from 2008.

And no, I'm not a friend of producing energy by nuclear fission. I totally out myself as a supporter of the green energy concept.
