(1,825 posts)The levels of Plutonium in Lithuania are consistent with what most of the world has.
The entire planet got a good "dusting" of Plutonium during the years 1945-1962 when the USA and the former Soviet Union due to atmospheric nuclear weapons tests. Those tests dusted the planet with over 10 metric tonnes of Plutonium.
Although nitwits like Helen Caldicott will tell you that a single kilogram of Plutonium in the environment will wipe out all life on the planet; and the above figure is 10,000 times what Caldicott says will destroy all life on the planet; the scientific truth is something else.
You can see how much that dusting of Plutonium is contributing to your radiation dose courtesy of the University of Michigan chapter of the Health Physics Society:

If you look at the entry "Fallout" you will see that the radiation exposure from all that Plutonium is <0.03% of the average person's annual exposure. Mother Nature is giving you over 3000 times the radiation exposure that you get from all that Plutonium.
The Plutonium found in Lithuania was tracked back to Fukushima. They found Plutonium in Fukushima and ASSUMED it must have come from Fukushima. They don't know that there is Plutonium spread all over the world courtesy of the USA and Soviet Union back in the '50s.
Fukushima added 2 grams of Plutonium to the 10 metric tonnes that the USA / Soviet Union already dusted us all with. TEPCO increased our Plutonium exposure by a trivial amount. The USA / Soviet Union did 500,000 times worse in Plutonium exposure to us than TEPCO did. We've been living with the Plutonium that the USA / Soviet Union distributed for more than half a century. However, the radiation due to all that Plutonium is really "small potatoes" compared to what Mother Nature is blasting us with.
I didn't ignore Art; I responded. Art didn't have any independent measurements. He lives there and can only confirm for us that the Japanese authorities have closed down areas. We didn't need independent confirmation from Art. Dr. Richard Muller and I both know that the Japanese authorities have closed down areas around Fukushima. What Dr. Muller was pointing out in his WSJ article is that the amount of radiation that is the limit for the Japanese authorities to close an area is one-third the amount of radiation exposure we tolerate in Denver.
Dr. Muller and I both say that there are areas of Fukushima prefecture close to the crippled plant that are higher than Denver; and we agree that the Japanese authorities should close those area.
The question is over the areas that are NOT as high as in Denver. The people in Denver are living healthy lives bathed in more radiation and the Denver authorities don't close down the city; when Japanese authorities are closing down areas that have a third of the "Denver dose".
Evidently you didn't get Dr. Muller's message from his WSJ article. Basically, Dr. Muller is saying that the Japanese authorities are "over-reacting" to the Fukushima threat. The only thing Art can confirm is that the Japanese authorities are reacting by closing down areas. Art can't tell us how much, or more to the point, how little radiation is causing the Japanese authorities to react.
