EPTlive stream report
they said the core has been exposed to air more than 6 hours. something wrong with the air pressure (water pressure) and untill now they only recovered half of it....

Thread is about the various issues surrounding Japan in the aftermath of the recent earthquake. Don't bring the shit side of the internet to the thread, and post with the realization that this thread is very important, and very real, to your fellow members. Do not post speculative and unconfirmed news you saw on TV or anywhere else. Generally the more dramatic it sounds the less likely it's true. | ||

Counts per minute (cpm) is a measure of radioactivity. It is the number of atoms in a given quantity of radioactive material that are detected to have decayed in one minute. Disintegrations per minute (dpm) is also a measure of radioactivity. It is the number of atoms in a given quantity of radioactive material that decay in one minute. Dpm is similar to cpm, however the efficiency of the radiation detector (e.g. scintillation counter) must be accounted for when analysing data in cpm. Dpm is the number of atoms that have decayed, not the number of atoms that have been measured as decayed. Dpm is commonly used as a measure of radioactive contamination. * One becquerel (Bq) is equal to one disintegration per second, or 60 dpm. * One curie (Ci) is equal to 3.7 x 10 10 Bq or dps, which is equal to 2.22 x 1012 dpm. The gray (symbol: Gy) is the SI unit of absorbed radiation dose of ionizing radiation (for example, X-rays), and is defined as the absorption of one joule of ionizing radiation by one kilogram of matter (usually human tissue).[1] It is named after the British physicist Louis Harold Gray. It supersedes the old cgs unit, the rad (10 mGy), which is now "strongly discouraged" by the author style guide of the United States National Institute of Standards and Technology, [2] though still commonly used within the US. The sievert (symbol: Sv) is the SI derived unit of dose equivalent. It attempts to quantitatively evaluate the biological effects of radiation as opposed to the physical aspects, which are characterised by the absorbed dose, measured in gray. In terms of SI base units: 1 Sv = 1 J/kg = 1 m2/s2 = 1 m2·s–2 SI multiples and conversions Frequently used SI multiples are the millisievert (1 mSv = 10−3 Sv) and microsievert (1 μSv = 10−6 Sv) or (1 mSv = 0.001 Sv) and (1 μSv = 0.000001 Sv). An older unit of the equivalent dose is the rem (Röntgen equivalent man[sic]). In some fields and countries, the rem and millirem (abbreviated mrem) continue to be used along with Sv and mSv, causing confusion[citation needed]. Here are the conversion equivalences: * 1 Sv = 1000 mSv (millisieverts) = 1,000,000 μSv (microsieverts) = 100 rem = 100,000 mrem (millirem) * 1 mSv = 100 mrem = 0.1 rem * 1 μSv = 0.1 mrem * 1 rem = 0.01 Sv = 10 mSv * 1 mrem = 0.00001 Sv = 0.01 mSv = 10 μSv 1 Gy = 100 rad 1 rad = 0.01 Gy 1 roentgen (R) = 258 microcoulomb/kg (µC/kg) 1 millicoulomb/kg mC/kg = 3876 milliroentgen (mR) Source: en.wikipedia.org Also consider these ones: http://en.wikipedia.org/wiki/Radiation_poisoning http://en.wikipedia.org/wiki/Sievert How to convert cpm to curies This makes my head spin! As if they were deliberately trying to confuse the people with tons of different measurement units. | ||

Borrowed from slashdot.org + Show Spoiler + by grumling (94709) Alter Relationship on Sunday March 13, @03:41PM (#35471094) Homepage Imagine you live in Rome. You are a civil engineer, in charge of building the first bridge. You build it the best you can, based on observing trees that fall across small streams. It is very dangerous, but effective for a few years. Several other people copy your design and build their own bridges using tree trunks. Meanwhile, someone else looks at your design and determines the bridge could be built much safer if you use an ads to flatten out the top, so that people can walk on the flat area, and some ropes along the sides at hand level let people keep their balance. You try it out and find it works very well. Meanwhile, people all over Rome are falling off the "Gen 1" bridges. People protest bridges to the Roman Senate and elect people who won't allow new bridges to be built, even with the safety features. To make matters worse, the existing bridges are now rotting. Several bridges have fallen into the creeks and many are too fragile to let more than one person across at a time. The tree bark, which provided at least some grip for people using the bridges is now gone, and when it rains the bridges are incredibly slippery. The Roman Senate funds a study to look into building "Gen 3" bridges. The engineers come back with designs for stone bridges, using the latest in geometry (the arch). The engineering community thinks this bridge will last for years, be incredibly strong and safe. But because the public has such a bad memory of the existing bridges, they want nothing to do with them. Meanwhile they demand the Senate fund more ferryboats for river crossings. thats only a good analogy if collapsing bridges would poison the rivers for thousands of years, and after the lifespan of the bridge youd have to store it somewhere safely for thousands of years too in that case ferrys would seem like a sensible alternative | ||

Someone should make an energy debate thread. I feel that alot of people here have alot to say on the subject. It could lead to an intresting conversation. Anyway, I really hope that this incident doesn't end up hurting too many people in japan. They're handling it very well, though, and I'm definately impressed by that! | ||

German Weekly Newspaper (Spiegel) heralded the end of the nuclear era yesterday ... for me and my familie who have been living in the shadows of the oldest power plant (that came close to a meltdown in 88 or something) and fighting against it since my childhood this brings atleast some relief in these dark times ... | ||

I can't believe it. There are people starving in Tokyo. I just can't believe it. I was born there and I grew up there, and it's the last place I'd have expected anyone to be starving in. | ||

Anyways I heard Japanese people are getting angry with the information flow to the public. --> They dont feel to get enough news and dont trust the ones they are getting. | ||

The plant is Kernkraftwerk Krümmel near Hamburg. As a source for it being the area with the highest rate of leukemia in the world it was in the "Hamburger Abendblatt" today and you can read about it on: http://de.wikipedia.org/wiki/Leukämiecluster_Elbmarsch Here is also a ZDF 30 min docu on it: http://www.videogold.de/und-keiner-weiss-warum-leukaemietod-in-der-elbmarsch/ | ||

So she tried calling an ambulance, but they're obviously all busy. So she tried to call a taxi, but they're all backed up at least 5-6 hours. So she got her son to go buy food -- 10 hours for a round trip. I can't believe it. There are people starving in Tokyo. I just can't believe it. I was born there and I grew up there, and it's the last place I'd have expected anyone to be starving in. Man this panic buying is really another big problem for Japan. Somehow the word has to get out that people should not do that. I saw it going around on twitter but I'm not sure how far it got. Now would be the time to ask your celebrity friends to make a tweet if you have any! | ||

Some dumbass analyst on NHK was telling people to stock up on food and essentials a couple days ago. I couldn't believe my ears. | ||

I don't know if this is off topic or not so I will only say this, I'm actually concerned that irrational fear over nuclear power may end up doing substantially more damage in the long term than the power plants at Fukushima could ever do. The fact of the matter is that any nuclear power plant that is shut down, must be replaced with one burning coal or oil. I don't think environmentalists should be partying over that :/ | ||

So if you show me a reliable source that proofs that every nuclear power plant that is shut down can only be and must be replaced by either oil or coal plants, feel free to do so. Edit: I guess we need a new thread for nuclear power overall too. It doesn't really belong here. User was temp banned for this post. | ||
