Are you saying that Fukishima is worse than all the atomic bombs we dropped all over the planet in the 1950s and 60s???
Nuclear bomb fission daughter particle generally decay into Iodine-131, which has a half-life of about 8-10 days.
When a nuclear reactor doesn't have enough carbon (or whatever) to absorb neutrons, a chain reaction occurs -
and some of the daughter particles produces have half lives of up to 100,000+ years.
So, if you get irradiated from breathing a mole of radionucleotides, for example, those particles will not stop emitting radiation until it decays into some other radionucleotide.
Obviously a core meltdown is bad but it is not the end of the world by any stretch.
It is an ELE, because the radionucleotides released were in massive amount's - leaked into air, soil and water. And, many of these particles emit radiation much longer than human's have existed on this planet. That means it can irradiated entire ecosystems - and has done so.
There are naturally occurring radioactive elements all over the world.
Naturally occuring radioactive particles are in such small activity, in such small density that the radioactive effects are negligible. Again, we are talking about magnitudes of radiation, not treating radiation as the bogeyman itself. You are exposed to radiation every day; the cross section, activity and amont of particles are important in determining radioactive strength in emission
Even a bunny rabbit has some amount of radiation.
The type, quantity, activity, decay rates and particle matter in radioactive analysis. If we are talking about C-14, for example, we can actually calculate the amount of radiation emitted in that rabit. In fact, I can show the mathematics/physics of how much radiation a bunny is exposed to from its own isotopic chemistry, as well as what it takes to produce the radiation at fukishima (if wanted.) It is nowhere near the same. The radiation emitted from Fukishima can kill a human in a matter of minutes - you won't live. We aren't talking about ambient radiation like x-rays or gamma rays (although those are certain radiation emitted,) we are talking about beta particles (elec/positrons,) alpha particles (helium nuclei,) neutrinos and neutrons being emitted. Usually a piece of paper, or shirt can block the first two from counting on your skin, since they are massive.
Obviously, Fukishima and meltdowns are more extreme but not to the point of one reactor going bad equating to the end of life on Earth...
Yes it is. There is NOTHING to stop the core from continuing. And, the radioactive particles or energy emitted also transmutates other matter. This is not an alarmist issue; this is a real extinction level event.
If that were the case, then please explain how the planet is still here after all the atomic bombs the US, Britain, France, and Russia exploded during the 50s and 60s as if we were having a global 4th of July....
Because Iodine 131 has a very short halflife, and the majority of daughter particles also have relatively short halflives. The contamination comes from nuclear/MOX waste, and other distillates used to make the bomb.
Sure, small local regions in the area will be affected, but overall we as a planet will be okay and will recover.
The entire planet has been affected already. You are just being told it is something else, because if you knew Fukishima was causing a current ELE - if ANYONE knew, then TEPCO, and Japan would be in serious global trouble from the people. They are already being disciplined for their sloppiness; the Asian government shake-ups aren't just because of the times, or egregious behavior. We are watching the contingency plans being enacted as we breathe - because we are categorically not part of those plans.
