Don't drink Tap water within 20 kilometers of Fukushima Nuclear plant

The latest news says "Don't drink any tap or well water within 20 kilometers of the nuclear plant and now the ocean is contaminated up to 60 kilometers out to sea in radius from the plant. Also, the radiation from #3 reactor with plutonium is 2 million times worse than ordinary uranium radiation for everything living on earth. If you remember reactor #3 is reprocessed fuel from nuclear weapons which is as I said above 2 million times more toxic to all life than ordinary uranium reactors are. It is said that the Chinese are moving forward with Thorium in their newest reactors because thorium is supposed to be safer. However, I have no documentation as to the fact that thorium is safer yet.

when I researched thorium at Wikipedia this is what I found:

Thorium (play /ˈθɔriəm/ THOHR-ee-əm) is a naturally occurring radioactive chemical element, found in abundance throughout the world. Thorium atoms (symbol Th) have an atomic number of 90, with 90 protons and 90 electrons, of which 4 are valence electrons. It was discovered in 1828 and named after Thor, the Norse god of thunder.
In nature, thorium is found as thorium-232 (100.00%). Thorium decays slowly by emitting an alpha particle. The half-life of thorium-232 is about 14.05 billion years. It is estimated to be about three to four times more abundant than uranium in the Earth's crust. It is a by-product of the extraction of rare earths from monazite sands. The formerly widespread uses of thorium, for example as a light emitting material in gas mantles or as an alloying material in several metals, have decreased due to concerns about its radioactivity.
Thorium-232 was used for breeding nuclear fueluranium (233), for example, in the molten-salt reactor experiment (MSR) conducted in the United States from 1964 to 1969. Most of the initial test reactors were closed down. However, countries including Russia, India, and recently China, have plans to use thorium for their nuclear power, partly because of its safety benefits.
