Caesium-137 in the environment is anthropogenic (human-made).
Caesium-137 (137 55Cs, Cs-137), cesium-137, or radiocaesium, is a radioactive isotope of caesium which is formed as one of the more common fission products by the nuclear fission of uranium-235 and other fissionable isotopes in nuclear reactors and nuclear weapons. It is among the most problematic of the short-to-medium-lifetime fission products because it easily moves and spreads in nature due to the high water solubility of caesium's most common chemical compounds, which are salts.
In April 2011, elevated levels of caesium-137 were also being found in the environment after the Fukushima Daiichi nuclear disasters in Japan. In July 2011, meat from 11 cows shipped to Tokyo from Fukushima Prefecture was found to have 1,530 to 3,200 becquerels per kilogram of Cs-137, considerably exceeding the Japanese legal limit of 500 becquerels per kilogram at that time.[7] In March 2013, the Japanese utility that owns the tsunami-damaged nuclear power plant said that it had detected a record 740,000 becquerels per kilogram of radioactive caesium in a fish caught close to the plant. That is 7,400 times the government limit for safe human consumption.[8]
Due to its mode of beta decay, iodine-131 is notable for causing mutation and death in cells that it penetrates, and other cells up to several millimeters away. For this reason, high doses of the isotope are sometimes less dangerous than low doses, since they tend to kill thyroid tissues that would otherwise become cancerous as a result of the radiation.

Forgive me for a bit of drift here but I'm confused. We take potassium iodine if exposed to iodine 131? And what would you take if exposed to this other toxin above? Does potassium iodine protect from that as well?

"Prussian Blue" a synthetic pigment is well known to reduce the half-life of Caesium-137 from 70 to 30 days by binding with it. That's the only known treatment that I know of.
Prussian blue traps radioactive cesium and thallium in the intestines and keeps them from being re-absorbed by the body.
The radioactive materials then move through the intestines and are passed (excreted) in bowel movements.
Because Prussian blue reduces the time that radioactive cesium and thallium stay in the body, it helps limit the amount of time the body is exposed to radiation.
Prussian blue reduces the biological half-life of cesium from about 110 days to about 30 days.
Prussian blue reduces the biological half-life of thallium from about 8 days to about 3 days.
People SHOULD NOT take Prussian blue artist’s dye in an attempt to treat themselves. This type of Prussian blue is not designed to treat radioactive contamination and is not made for that purpose. People who are concerned about the possibility of being contaminated with radioactive materials should go to their doctors for advice and treatment.
People said Chernobyl would end the world and leave swathes of uninhabitable land and guess what, they were wrong. Nature reclaimed things quite quickly and shortly after residents were moving back in to their homes.
I was also tracking UC Berkely measurements at one time. Their measurements are more sophisticated than people walking around with Geiger counters.

Forget this fool with a counter. Look at some real studies of the area.
I live in Oakland. In April, UC Berekely Department of Nuclear Engineering did a measurement of Iodine-131 and Caesium-137 levels in plants, top soil, and wild mushrooms.
So, there was a lot of radioactivity in seawater even before man started adding to it. Don't assume the spikes on the Geiger counter are all Fukushima related.
The partial inventory of natural radionuclides in sea water in Table 1 (see page 22) amounts to 1–2 × 10 22 Bq, without including the uranium daughters or the 232 Th series nuclides. Human-made nuclides in the ocean have been estimated to be 85 × 10 15 Bq directly dumped, 1.5 × 10 18 Bq from fallout, and 1 × 10 17 Bq from reprocessing plant effluent. The natural radionuclides are greater in abundance.

If you had bothered to read my other posts you would understand that I hold both environmentalists and corporate types guilty of peddling nonsense for their own gain. Greenpeace is run by a very slick media savvy individuals who left the world of real science long ago and now sensationalise everything. I am fully aware of what large corporations do too. But, as is often the case on ATS people grab and run with a quote and don't bother reading … 'buddy'.
Geiger counters in the hands of citizens found 150 CPM coming from the ocean.
► Fukushima radiation hits San Francisco
Let’s start by doing the math on what 150 CPM (counts per minute) means. One Bq is 1 decay event per second. So divide CPM by 60, and you have Bq detected. This article detected 2.5 Bq. But in your body, on a normal day, you have 4,400 Bq. See: Wikipedia on Bequerel
So why is there radiation found near the ocean, and 5 times what’s on land? Most people have no idea that there are 3.2 tons of natural uranium in every cubic kilometer of ocean. (13.34 tons per cubic mile.) The ocean has a total of 4.2 billion tons of uranium in it. So, yeah. When you go near the ocean, you find radiation. But it’s always been there. There’s also potassium-40, radium, polonium-210. Like the spaghetti sauce, you name it, it’s in there. And it’s perfectly fine. It’s in your sea-salt.
The fuss is about fish caught off the coast of Japan with levels of radioactivity that are too high to be safe to eat. That problem can be attributed directly to the Fukushima disaster, and has nothing to do with natural radiation.

What's all the fuss about then?
Yes there is something seriously wrong.
No, thanks, I think there is something seriously wrong and I for one don't care how much natural radiation is in the ocean, products of fusion cock-ups do not bode well as far as I am concerned.
