So is there a news blackout in effect in Japan? I haven't heard or read anything new all day...
It's amazing what not reading, studying, or researching a subject will do for preventing you from knowing much about it.
So is there a news blackout in effect in Japan? I haven't heard or read anything new all day...
Rolling blackouts because their power plants are overworked
oh my bad u meant news blackout
read last 4 pages of this thread...
None of thats new stuff...
Apparently no news is good news...

(Reuters) - The situation at Japan's Fukushima Daiichi nuclear power plant was serious but "reasonably stable" Thursday with no major worsening since the day before, a senior U.N. nuclear watchdog official said.
We really need to see what the total amount of fallout is first before we can talk about its potential effects, if any, on the global food chain.
Dose is inversely proportional to the mass irradiated as well. This will mean less dose for larger organisms. Again, how much dose exactly will depend on the fallout mass.
For now, feel free to take a step back from the ledge.
The major Iodine isotope which is present in radioactive fallout of this nature is I-131. It has a half life of 8 days meaning that it will take just over 2.5 months for it's dose contribution to be considered negligible. Potassium Iodide does nothing to counteract cesium 137. You'd need Prussian Blue for that. 1g TID.
Both of these emit betas and gammas, with both gammas being fairly energetic. The RBE (relative biologic effect) for both is the same though meaning the dose equivalents are the same whether or not you're exposed externally or internally. Distance tends to help with beta emissions as they have a range in air on the order of 10-15 feet.
Read about stochastic biologic processes and molecular cancer induction in your spare time. You might catch on to why those things are not discussed in definite terms as you'd prefer.
Oh, and I don't claim to "know" ........I claim to "know ".
They're talking about magnitude here, not the quality of the radiation. Quite actually, given the choice you'd want the Pu radiation against your ear. It's an alpha emitter and as such is blocked by your skin. Just make sure to switch ears when the heat builds up.

Nothing like a disaster to motivate people to learn. I will absolutely admit, I have learned more from what has been posted here the last few days (primarily from agloco) than I had the previous 31 years of my life. Why? because I have never needed it and nothing had happened to pique my interest to study it for the sake of studying it.
More than likely Amifostine and Atropine.
What ever it was I think its for moral and motivation. Nerve gas once it hits you all the needles in the world is not going to do .
It's like giving someone who lost a leg 1/2 off at payless shoes. I was at secret meeting back in 1980 were our group was shown a video of how the gas mask used by the Army compares to the gas mask used by the USSR.
They had six animals in a room 3 had USSR gas masks 3 had US Army gas masks
they released a very small vile of Nerve gas in seconds 4 animals started to shake the three with the US Army gas masks lay down and died one with the USSR mask died but after it shook longer, and two lived. they were wearing the USSR gas mask.
We knew the American forces were ed, It takes years for the military to change their gear. So many of us at Bragg purchased our own masks from a supplier who sold AK 47s and other Russian .
That video was Russian propaganda to get the stupid soldiers to throw away their good US masks and buy surplus Russian ...
lol generic animals
Latest meltdown

Like a black fly in my chardonnay? Or a death-row pardon 2 minutes too late?
I figured that since most residents tune me out at 5am and most graduate students do the same no matter the time of day I'd give it a whirl in a local sports forum. Who knew?
Glad I could be of service to you.
Capitalism at work.
Actually, the nerve gas needle is fairly effective, assuming you use it AS SOON as you recognize symptoms. Like, within the first minute.
Otherwise, yeah you're probably screwed.

Dangerous Fallout From Japan’s Nuclear Panic
With news of Japan’s once-in-300-year earthquake and resulting tsunami, Secretary Clinton announced “We just had our Air Force assets in Japan transport some really important coolant to one of the nuclear plants.” Rep. Ed Markey (D., MA) has warned of “another Chernobyl,” saying “the same thing could happen here.” Amidst the chaos, the media has been reporting on the next “big fear” and CNN has shown their ignorance by presenting schematics of pressurized water reactors, when the Japanese reactors are boiling water reactors.
Because the concept of nuclear power is foreign to most of us, panic is easily created. Senator Lieberman, a long-time nuclear supporter, now wants to “put the brakes on” nuclear power plant construction in the US. Those who really understand nuclear energy usually have advanced degrees in physics. Words like reactors, meltdown, core damage, neutrons, half-life and radioactive, make us susceptible to Hollywood-like, worst-case scenarios.
In fact, the US did not send “coolant” to Japan. Remember, the plants in Japan operate on water—usually de-mineralizd. In this earthquake/tsunami drama, the plants perfectly withstood the first hit of a 9.0—even though that was considerably more intense than the intended design. The redundancy engineered into the system kicked in. Though the reactors shut down as they were supposed to, they do not cool off immediately. The diesel-powered generators pumped the water to continue cooling. Then the wave hit and knocked them out. Even then, batteries kept the pumps working until mobile generators could be brought in. These procedures bought time and allowed for precautions. With the help of the additional generators, seawater (abundant in an island nation) has been used to expedite the cooling—even though its corrosiveness means the reactors will never be usable again. The more time elapsed, the cooler the fuel. The longer this goes on, the greater the likelihood that the only thing overblown is fear.
The Chernobyl comment, once again, plays on a fundamental lack of understanding (or deliberately ignores scientific principles of nuclear energy) and stirs up fear. What happened with the Chernobyl reactor, is not possible with the Japanese or US light water reactors. The designs are fundamentally different and that plant could not have been licensed here or in Japan. Today’s nuclear plants have corrected the flaws with lessons from the Chernobyl incident. Likewise, the failure of the generators that provided electricity to pump the cooling water following the tsunami (Generation II design) have already been fixed in current designs (Generation III).
So what is the fear? Why is the news media all nuclear, all the time?
The concern is the potential exposure to high levels of radiation. This, too, is an overreaction. Bad news sells. As was revealed through a comment made during a hearing in which I participated for proposed uranium mining, the public perception is that there is “no acceptable amount of radiation”—which implies that radiation is a man-made, bad thing, not naturally present in nature. The NY Times reported that “Radiation levels around the plant ed after the explosion to 8,217 microsieverts an hour…” Which sounds really scary if you do not understand that 8,217 microsieverts an hour is equivalent to 0.8 rem/hour (10 millisieverts = 1 rem). Background radiation (that naturally found in nature) is around 0.3 rem/yr and workers are allowed 5 rem/yr. So this “ e” says that you should avoid being near the plant for more than a few hours. This is a problem because the pool of workers with the needed expertise is limited. Now experts from across the globe are arriving in Japan to help out. If the situation were truly threatening, those from other countries who know better would not voluntarily walk into the plant.
To put “radiation” into perspective, natural radiation comes from cosmic rays and the sun. Those of us who live at a higher al ude receive 2-3 times the radiation of those at sea level. The atmosphere provides some shielding. Mountain dwellers receive more radiation in a year than nuclear power plant workers get at sea level. Flat-landers are often surprised at how quickly they get sun burned when they are at higher elevations. One of the biggest concerns about radiation is cancer—which is why there is such emphasis on sunscreen.
Additionally, radiation comes from minerals found in mountainous places such as the Rockies. The combination of the high al ude and the naturally occurring radioactive minerals gives someone in Denver annual radiation exposure of two to three times the radiation exposure of someone on the East Coast—yet Denver is repeatedly one of America’s healthiest cities. Health studies have found that populations who live and work near uranium facilities have no differences from those who do not. Clearly there is “acceptable” radiation; we live in it all the time. Workers and residents in Japan are being monitored.
Japan has 55 nuclear reactors and 30% of their electricity comes from nuclear power. Thirteen reactors, at three power plants were in the quake zone. Of those, only one has released any increased radiation, They basically let off steam—which contained low levels of radioactivity. Because of seawater being used as “coolant,” the steam is slightly more radioactive due to the salt and other trace minerals in the ocean. The steam was deliberated vented into ancillary buildings to allow the reactor vessels to cool. However, inside the buildings, hydrogen that came out of the steam blew the roof off. This made great television and added fear, but the containment vessels and their systems remained intact. The blast was not a “nuclear explosion” and was a known and accepted risk that successfully allowed the radioactivity to diminish at the site.
Preoccupation with the nuclear plants has diverted attention from the much greater tragedy that has taken place—the likely death of over 10,000 persons from the earthquake and tsunami that has struck Japan. As William Tucker said in the Wall Street Journal, “With all the death, devastation and disease now threatening tens of thousands in Japan, it is trivializing and almost obscene to spend so much time worrying about damage to a nuclear reactor.” The biggest crisis inflicted on Japan would have occurred with, or without, nuclear power.
As humans, we cannot control the earth—though we sure do try, but we feel we can control other eventualities. Hence, the intense focus on the reactors and radiation. We can control them. We should learn from the past, but move into the future.
Instead of offering suggested improvements as a result of the Japan earthquake, Senator Lieberman wants to put the brakes on American nuclear development. Yes, questions should be asked. The biggest one should be about an all-of-the-above energy portfolio: oil, gas coal, nuclear/uranium, hydro, wind and solar—unlike Japan, we are rich in resources. Without nuclear power, America could be facing the same supply-demand gap a post-earthquake Japan is experiencing. Blackouts are causing mass confusion and delays. Consumers are being asked to cut back on energy.
What we can learn from the Japan earthquake is that the forty-year old nuclear power plant design performed better than expected. And, like the Fukushima Daiichi plant is far advanced and a completely different design than Chernobyl. Today’s Generation III and IV reactors are literally generations ahead of their predecessors. In the US we have twenty-one applications for new reactors.
Our energy needs will not go down, but, if we allow the nuclear panic to reign, our energy availability will be reduced. Before nuclear power was embraced in Japan, they relied on imported oil, gas and coal for their energy. Without nuclear power, we, too, will have to be more dependent on fossil fuels.
The most dangerous potential fallout from Japan’s earthquake could be the inability to be energy autonomous in thirty years. America’s future mandates a greater emphasis on energy and nuclear energy is an important part.
But you must admit you can see how the average Joe is misinformed. So I will try another analogy.
If you start to feel another mans penis enter your ass your gay no matter how fast you react to it.
(that was for the johnsmith's of the forum who may not get the "it's too late" scenario).
Finally, a cooler head prevails.What we can learn from the Japan earthquake is that the forty-year old nuclear power plant design performed better than expected. And, like the Fukushima Daiichi plant is far advanced and a completely different design than Chernobyl. Today’s Generation III and IV reactors are literally generations ahead of their predecessors.

Prevails is probably the wrong word... at the very least it is too soon to use that word.
http://www.latimes.com/news/la-fg-ja...ntent=My+YahooU.S. government nuclear experts believe a spent fuel pool at Japan's crippled Fukushima reactor complex has a breach in the wall or floor, a situation that creates a major obstacle to refilling the pool with cooling water and keeping dangerous levels of radiation from escaping.
That assessment by U.S. Nuclear Regulatory Commission officials is based on the sequence of events since the earthquake and information provided by key American contractors who were in the plant at the time, said government officials familiar with the evaluation. It was compelling evidence, they said, that the wall of the No. 4 reactor pool has a significant hole or crack.
Unlike the reactor itself, the spent fuel pool does not have its own containment vessel, and any radioactive particles and gases can more easily spew into the environment if the uranium fuel begins to burn. In addition, the pool, which contains 130 tons of uranium fuel, is housed in a building that Japanese authorities say appears to have been damaged by fire or explosions.
Japanese considering encasing the entire plant in concrete.
Damn mouse called it! mouse owning mofos up in this threads!
That's only possible to do if it's sufficiently cooled so that the fuel won't melt through the concrete. Mouse was simply regurgitating information from the Chernobyl disaster without knowing anything about it. Right now it's a last-ditch effort from them. Completely different scenarios.Japanese considering encasing the entire plant in concrete.
Damn mouse called it! mouse owning mofos up in this threads!
Saying that is kinda like saying your pot will get hot when you turn on the stove. Hardly ownage.Japanese considering encasing the entire plant in concrete.
Damn mouse called it! mouse owning mofos up in this threads!
Nuclear plant chief weeps as Japanese finally admit that radiation leak is serious enough to kill people

so they have until Sunday to restore power and control situation or else they will bury the plant.
Things looking good because French lowered nuclear level to a 5 today.
