worse, why isn't it obvious already?
I'm not doubting this. I'm only asking to understand.
There are several answers to these questions.
The first being that it's a lot of guesswork as the damage is so extensive and radiation levels are so high that no one has been able to get very far
into the reactor buildings since the explosions. Robot's electronics degrade as well and soon become unusable. You can watch the image quality visible
detiorate the deeper the robots go into the reactor buildings. HD video shows such a large number of gamma strikes to the CCD that it looks like
they're in a snow globe.
The 10 Sv/hr dose rates are fatal within seconds. This level of emission is almost incomprehensible anywhere outside the reactor itself.
The danger to all of us, regardless of distance from Fukushima Daiichi, is the aerosolized bestiary of isotopes that have been and will continue to be
released through steam into the atmosphere and through leakage into the Pacific Ocean. Don't buy the little tank charade, not for a length of Planck
Educated guesses can be made at the amount and roughly the types of isotopes we're likely to encounter through analyzing the amount in fuel in each
reactor (don't forget 40 years worth of spent fuel, this so where the largest inventory of contaminants is), but due tithe random nature of radiative
decay and the effects of neutron radiation, you never rally know exactly what you're gonna get.
It's much worse than Pandora's box, at least with that you could crawl in the box to save yourself.
Now on to Bioaccumulaion.
As these aerosols come into contact with a variety of
surfaces (soil, leaves, the ocean) they will begin to enter the food chain. They'll start out down at the bacterial or plankton level and work their
way up. Into plants that are eaten by animals which either produce products (milk for example) or are eaten themselves, the radiation hitches a ride
and goes along too.
Google "radioactive sludge" and you will see and example of what I have called industrialaccumulation. The particles are rained out, enter a municipal
water treatment facility where they are concentrated down to solids which are then often incinerated(re-aerosolizing the particles to be taken back up
into the environment).
And as for Tepco's circus tent, it's the equivalent of using a cheesecloth condom (can't remember who made that analogy in the thousand plus page
thread, but I love it). With sub micron particle size, that polyester tarp won't stop squat. It's merely to block the view of what they don't want
seen. Remember that mindset of the Japanese of if it can't be seen, then it's not a problem.
