At the levels of radiation now being found a Fukushima, a robot would be able to operate for less than two hours before it was destroyed. And Japans National Institute of Radiological Sciences said medical professionals had never even thought about encountering this level of radiation in their work.
The accident is enormous in its medical implications. Through future years, too long to contemplate, we will witness an epidemic of cancer as people inhale the radioactive elements, eat radioactive vegetables, rice and meat, and drink radioactive milk and teas. Year by year, decade through relentless decade, the radiation will build up yet modern medicine does not seem concerned.
New readings at Fukushima have recorded the highest radiation levels seen since the triple core meltdown that occurred in 2011. Readings inside the containment vessel of reactor no. 2 are as high as 530 Sieverts per hour, a dosage that would be fatal dozens and dozens of times over if a human were to be exposed to it. The previous high was a still very fatal rate of 73 Sieverts per hour.
The blazing radiation reading was taken near the entrance to the space just below the pressure vessel, which contains the reactor core. The highest radiation levels ever measured at Chernobyl were 300 Sieverts per hour; an incomprehensibly high dose which can kill a man almost instantly.
The new record at Fukushima of 530 Sieverts per hour is 70% higher than that of Chernobyl. The 530 Sievert reading was recorded some distance from the melted fuel, so in reality it could be 10 times higher than recorded, said Hideyuki Ban, co-director of Citizens Nuclear Information Center.
To put this in perspective, radiation is usually measured in thousandths of a Sievert, called millisieverts. For example, most people receive around 2.4 millisieverts per year from background radiation, or only 0.0002739726 per hour.
According to the Kyodo news agency, the institute estimates that exposure to one Sievert of radiation could lead to infertility, loss of hair and cataracts. One Sievert is enough to cause radiation sickness and nausea; 5 Sieverts would kill half those exposed to it within a month, and a single dose of 10 Sieverts would prove fatal within weeks.
Well, some Japanese knew something about how high a water level could go. They put that big rock at just about the high water mark.
Greenies’ protests forced all those plants to be bunched up, too.
I thought that was Baptists? or did I take the Green bean casserole to the wrong place again?
I've actually had many dreams lately where the skies were filled with UFO's fighting each other. It scares me awake so I remember them. I'm old so the bathroom dreams I remember speak for themselves.
“Gray and rems are used to describe exposure to persons when studying the dead and dying. MDs and physicists PhD types.
Exposure through standard work exposure still use the relatively new adopted measurement Sieverts and millisieverts and more commonly used measurements for industrial radiation workers are still allowed 5 R per year, every year and no upper nor maximum limit for ones lifetime.”
5 rem, not 5 R.
REM and Sievert are equivalent with a multiplier.
“They were highly educated but had zero questioning attitude. a cultural STRONG cultural thing in Japan.”
In Indonesia as well. My client called their engineers “automatons”. “If you want the equation for the angle of degree of the mine shaft in rock with a density of ‘d’ they can give it to you right then off the top of their head. However, if they come across a problem in real life while digging the shaft they got no clue!”
Taiwan was similar.
“If they’d just sited their backup generators and power lines better they probably could maintained coolant power and prevented the meltdown. “
They were running on the diesel generators when the Tsunami hit. If the operator had just reached over and hit the E-stop on the generators when they saw the waterline recede they would not have hydro-locked the engines. They could have gotten something back online in time to avert meltdown.
And all of the water discharged you Fukishima is processed so as to meet discharge permit requirements. Low activity.

It’s probably one of the most freakish aspects of Fukushima. The radioactive fuel escaped containment and radioactive isotopes are found in wells around the plants. It is in the water table. I dont’ know if they are still flushing it but for many years after the melt downs, TEPCO continued to force tons of water over the fuel to keep it from heating up and that water was NOT contained. Tons and tons of radioactive water table water venting into the ocean - an open secret. Meanwhile they put up a cheap tank farm, and then worried that the tanks were falling apart and processing equipment continued to fail.
They then announced they would be dumping the tank water into the ocean. https://www.newsweek.com/fukushima-nuclear-waste-dumped-ocean-japanese-protests-637108
But that’s only Tritium. There are other isotopes - many others - loose around Fukushima. People who watched the Fukushima cams noted steam rising through open cracks around the perimeter of the plant and the power company acknowledges the fuel is a) not contained and b) cannot be contained. So the fuel cores of those plants are making their way into the soil, air and water. That’s why the theatre aspects of those tanks full of tritium water seems bizarre. “Look over here! Not over there!”
Semantics, or misunderstanding in unit labels
R = rem not rad.
R = roentgen equivalent man (or rem), not rad, defined as 1 rad = 0.01 Gy (gray)
[which at the conversion, 1 roentgen deposits 0.877 rad in dry air, 0.96 rad in soft tissue, or anywhere from 1 to more than 4 rad in bone depending on the beam energy. Could be considered materially the same or vastly different depending on either context, the expert or both]
5R = 5,000 mR.
5 R = 5 roentgen or 5000 mR.
Named for/after Wilhelm Röntgen. (An under appreciated/ known powerhouse with the likes of other early pioneer heroes. I digress, though it is a subject near to mt geek heart. A book could/ should be written with a chapter on each of these almost unknown Paladins.)
Wiki: “There is no universally applicable conversion constant from rad to rem; the conversion depends on relative biological effectiveness (RBE).”
I agree with the above paragraph,
The measurements are used by industrial workers recording their allowable exposures, cumulative for the year, not to exceed 5R. Rads are exposures physicists and MDs (used to) to study the damage caused by those exposures, though if a person is looking at historical studies they are labelled R, and referencing rads, which adds to the menacing extra step converted numbers that are either really close or vastly different values depending on the volume/amount and the difference between exposure vs. damage.
Six one way and half a dozen the other.
This statement is either seen as materially different but substantially the same, a discussion on semantics or a discussion of items that use the same arabic numerals discussing different however similar.
Sometimes the differences are subtle or massive.
Perhaps this helps clear the conversation, or makes it more muddled. Not certain how the information will be recieved.
The difficulties of discussions in print vs. spoken conversations.
I hope this time I have been more clear.
I do not consider either sites to be “Hell holes on earth”. There are many sites and sights in various locations above and below the surface of this earth that are dangerous to humans, and yet are fascinating. Vents, plumes, volcanoes, etc. Energy and its display is admired by many by its volume and/or unique features/properties.
Based upon my interests in both sites, I do desire that eventually they could retrieve images of the “den of the dragon” , the innermost areas of Fukushima, just as they were able to retrieve of Chernobyl.

“R = rem not rad.”
No. R = röntgen
