As you can see from the graphic just after the Fukushima multiple meltdowns including one reactor that was reprocessing weapons grade plutonium, that the Cesium or (Caesium) on the air since March of 2011 in Japan has been and continues to be problematic for life on earth especially in the Northern Hemisphere. Below I will put the source article for the above graphic.
Cesium Fallout from Fukushima ALREADY Rivals Chernobyl
As I’ve previously noted, many experts say that the Fukushima plants will keep on leaking for months. See this and this.
And the amount of radioactive fuel at Fukushima dwarfs Chernobyl.
As the New York Times notes, radioactive cesium is the main danger from the Japanese nuclear accident:
And see this.
But anyone who believes that Fukushima cannot possibly become as bad as Chernobyl has no idea what they are talking about.

Though the danger from radioactive iodine has gone away because of it short half life of under one month the danger of radioactive Cesium with a half life of around 30 years. So, as all this Cesium circles the globe on the winds clouds air and then most eventually comes to earth with the rain, snow, hail and winds worldwide, it is important to note that even one particle of Cesium on a dust mote that lodges in any person or animals lungs likely will be fatal to that human or creature within 20 to 30 years. Also, since one of the Meltdowns in Japan was a reprocessing plant for weapons grade plutonium, it is important to note that plutonium has a half life of:
begin quote from wikipedia under the heading "Plutonium":
Plutonium is the heaviest primordial element by virtue of its most stable isotope, plutonium-244, whose half-life of about 80 million years is just long enough for the element to be found in trace quantities in nature.[3] Plutonium is mostly a byproduct of nuclear fission in reactors: Some of the neutrons released by the fission process convert uranium-238 nuclei into plutonium.[4]
One utilized isotope of plutonium is plutonium-239, which has a half-life of 24,100 years. Plutonium-239 along with plutonium-241 are both fissile, meaning the nuclei of their atoms can split when bombarded by thermal neutrons, releasing energy, gamma radiation and more neutrons. These neutrons can sustain a nuclear chain reaction, leading to applications in nuclear weapons and nuclear reactors.
Plutonium-238 has a half-life of 88 years and emits alpha particles. It is a heat source in radioisotope thermoelectric generators, which are used to power some spacecraft. Plutonium-240 has a high rate of spontaneous fission, raising the neutron flux of any sample it is in. The presence of plutonium-240 limits a sample's usability for weapons or reactor fuel, and determines its grade. Plutonium isotopes are expensive and inconvenient to separate, so particular isotopes are usually manufactured in specialized reactors. end quote from Wikipedia under the heading "plutonium"
So, since weapons grade plutonium is most likely Plutonium 239 that was being reprocessed at Fukushima in one of the reactors and since it's half life is 24,100 years, this is what all life on earth is being exposed to for the next 24,100 years. For now, mostly it likely is all over the northern hemisphere. But eventually it will be everywhere.
It is important to note that Cesium is how art forgeries are found because literally everything on earth has some cesium in it since World War II and Hiroshima and Nagasaki. So, to find an art forgery all they have to do it to check for cesium. If the paint has cesium in it it isn't a Rembrandt. So, all of us have Cesium in us since World War II as well as every living thing on earth since World War II.
And the amount of radioactive fuel at Fukushima dwarfs Chernobyl.
As the New York Times notes, radioactive cesium is the main danger from the Japanese nuclear accident:
Over the long term, the big threat to human health is cesium-137, which has a half-life of 30 years.So it is bad news indeed that, as reported by New Scientist, cesium fallout from Fukushima already rivals Chernobyl:
At that rate of disintegration, John Emsley wrote in “Nature’s Building Blocks” (Oxford, 2001), “it takes over 200 years to reduce it to 1 percent of its former level.”
It is cesium-137 that still contaminates much of the land in Ukraine around the Chernobyl reactor.

Cesium-137 mixes easily with water and is chemically similar to potassium. It thus mimics how potassium gets metabolized in the body and can enter through many foods, including milk.
Radioactive caesium and iodine has been deposited in northern Japan far from the Fukushima Daiichi nuclear plant, at levels that were considered highly contaminated after Chernobyl.While Japan has been exposed to very high levels of cesium, so far, the levels of cesium in other parts of the world appear to be relatively low:
The readings were taken by the Japanese science ministry, MEXT, and reveal high levels of caesium-137 and iodine-131 outside the 30-kilometre evacuation zone, mostly to the north-north-west.
***
After the 1986 Chernobyl accident, the most highly contaminated areas were defined as those with over 1490 kilobecquerels (kBq) of caesium per square metre. Produce from soil with 550 kBq/m2 was destroyed.
People living within 30 kilometres of the plant have evacuated or been advised to stay indoors. Since 18 March, MEXT has repeatedly found caesium levels above 550 kBq/m2 in an area some 45 kilometres wide lying 30 to 50 kilometres north-west of the plant. The highest was 6400 kBq/m2, about 35 kilometres away, while caesium reached 1816 kBq/m2 in Nihonmatsu City and 1752 kBq/m2 in the town of Kawamata, where iodine-131 levels of up to 12,560 kBq/m2 have also been measured. “Some of the numbers are really high,” says Gerhard Proehl, head of assessment and management of environmental releases of radiation at the International Atomic Energy Agency.
And see this.
But anyone who believes that Fukushima cannot possibly become as bad as Chernobyl has no idea what they are talking about.
