There was no background radioactive cesium before above-ground nuclear testing and nuclear accidents started.
Wikipedia provides some details on the distribution of cesium-137 due to human activities:
Small amounts of caesium-134 and caesium-137 were released into the environment during nearly all nuclear weapon tests and some nuclear accidents, most notably the Chernobyl disaster.
***
Caesium-137 is unique in that it is totally anthropogenic. Unlike most other radioisotopes, caesium-137 is not produced from its non-radioactive isotope, but from uranium. It did not occur in nature before nuclear weapons testing began. By observing the characteristic gamma rays emitted by this isotope, it is possible to determine whether the contents of a given sealed container were made before or after the advent of atomic bomb explosions. This procedure has been used by researchers to check the authenticity of certain rare wines, most notably the purported “Jefferson bottles”.
As the EPA notes:
Cesium-133 is the only naturally occurring isotope and is non-radioactive; all other isotopes, including cesium-137, are produced by human activity.
What people call “background” radiation is really the amount of radiation deposited into the environment within the last 100 years from nuclear tests and nuclear accidents (and naturally-occurring substances, such as radon).
2,053 nuclear tests occurred between 1945 and 1998:
Above-ground nuclear tests – which caused numerous cancers to the “downwinders” – were covered up by the American, French and other governments for decades. See this, this, this, this, this and this.
But the amount of radiation pumped out by Fukushima dwarfs the amount released by the nuclear tests.
As nuclear engineer and former nuclear executive Arnie Gundersen notes, the wave of radioactive cesium from Fukushima which is going to hit the West Coast of North America will be 10 times greater than from the nuclear tests (starting at 55:00).
This graphic from Woods Hole in Massachusetts – one of the world’s top ocean science institutions – shows how much more cesium was dumped into the sea off Japan from Fukushima as compared to nuclear testing and Chernobyl:
(And Fukushima radiation has arrived on the West Coast years earlier than predicted.)
The Canadian government has confirmed in October that Fukushima radiation will exceed “levels higher than maximum fallout” from the nuclear tests.
The party line from the Japanese, Canadian and American governments are that these are safe levels of radiation. Given that those countries have tried to ban investigative journalism and have tried to cover up the scope of the Fukushima disaster, people may want to investigate for ourselves.
For example, Gundersen notes that the U.S. government flew helicopters with special radiation testing equipment 90 days after the Fukushima meltdown happened. The government said it was just doing a routine “background radiation” check, but that it was really measuring the amount of “hot particles” in the Seattle area (starting at 27:00). Hot particles are inhaled and become very dangerous “internal emitters”. The government then covered up the results on the basis of “national security”.
As the Washington Department of Health noted at the time:
A helicopter flying over some urban areas of King and Pierce counties will gather radiological readings July 11-28, 2011. [Seattle is in King County.] The U.S. Department of Energy’s Remote Sensing Laboratory Aerial Measurement System will collect baseline levels of radioactive materials.
**
Some of the data may be withheld for national security purposes.
Similarly, the Department of Homeland Security and National Nuclear Security Administration sent low-flying helicopters over the San Francisco Bay Area in 2012 to test for radiation. But they have not released the results.
Indeed, residents of Seattle breathed in 5 hot particles each day in April of 2011 … a full 50% of what Tokyo residents were breathing at the time:
After all, the reactors at Fukushima literally exploded … and ejected cladding from the reactors and fuel particles. And see this.
Gundersen says that geiger counters don’t measure hot particles. Unless the government or nuclear scientists measure and share their data, we are in the dark as to what’s really going on.

Just *WHEN* is this radioactive wave supposed to “hit” the West Coast of North America. And WHERE is it now. It should be trivially easy to find with relatively low cost equipment. Just sample some water – send it to a lab. Where is the wave RIGHT NOW?
“Hysteria fatigue” is setting in for this story.

“What people call “background” radiation is really the amount of radiation deposited into the environment within the last 100 years from nuclear tests and nuclear accidents (and naturally-occurring substances, such as radon).”
this is a false statement. Uranium, thorium, potassium 40 Radon, and carbon 14 were present since the earth was created and and many have decay products that are also radioactive. Add to this radiation from deep space and the sun is also a source of radiation.
“Some of the data may be withheld for national security purposes.”
state of the art radiation monitoring equipment is present at each hospital, nuclear power plant, and most universities and many companies. How could any government withhold the news when anyone using the equipment could post the readings on Facebook. The Soviets tried to keep Chernobyl secret but as soon as the radiation drifted over Europe people stated asking questions.

Hot particles breathed in or eaten, are the biggest danger and will give you cancer. And the hot particle does not much get detected by Geiger counter. the far right pro nuclear church goers, deny it cause they pray to Jesus make their GE and BW stock shares go up. What they care you got cancer, if they got Escalade, offshore tax free accounts, and money to throw into the plate. If you won’t believe, then you can choke on their nuclear dust.

Thanks for the link. The *peak* radiation level in the samples measured were 0.9 bq per liter. That means if you drank that entire liter of water (about a quart), you would ingest 0.9 bq of Cs-137.
On the other hand, if you ate a typical banana (or potato) you would ingest about 15 Becquerels of K-40 – a naturally occurring isotope of Potassium.
In both the case of potassium and cesium, there is an additional factor – these elements have a *biological half-life* – your body excretes the elements such that your tissues do not accumulate the element – unlike the more serious Strontium which _accumulates_ in the bones.
So I thank you for your post – it does show that the radiation from the Japanese disaster *has* spread out and dispersed to non-dangerous levels – thankfully.
Are there areas of Japan and the Japanese ocean which are seriously contaminated? – you betcha.
