Comprendre l'accident de Fukushima en 3 minutes
BERNARD DOMINIQUE il y a 102 semaines Le titre de l article nous prend vraiment pour des cons, je suis docteur en physique , militant antinucléaire depuis 1975 et je ne suis pas personnellement capable de comprendre l accident de fukushima en trois minutes en particulier tout le processus de mis en place des centrales, des lobbys qui ont permis leur construction, des décisions démocratiques qui y ont été associees, je ne parle pas des conséquences a court et moyen terme alors assez de la société du spectacle et du loisir répondre La réaction aux articles est réservée aux abonnés du Monde.fr <p style="text-align:right;color:#A8A8A8"></p>
What Price the Fukushima Meltdown? Comparing Chernobyl and Fukushima Matthew Penney and Mark Selden On April 12, 2011 the Japanese government officially announced that the severity of the Fukushima Daiichi nuclear disaster had reached level 7, the highest on the International Nuclear Event Scale. Before Fukushima, the only level 7 case was the 1986 Chernobyl disaster, whose 25 th anniversary was marked on April 26. Two and a half months after the 3.11 catastrophe, the first to affect multiple reactors, TEPCO and the Japanese government continue to struggle to bring the reactors at Fukushima Daiichi under control.

Safety Limits: What are they? How are they determined? Much of the discussion concerning radiation levels and radioactive material releases has been presented in the context of safety limits set by a regulator.

Today the Japanese Nuclear and Industrial Safety Agency revised its INES rating of the Fukushima Daiichi event. The previous assessment treated the events at each of the ailing reactors as separate: the core damage to units 1-3 resulted in an assignment of a 5 (accident with wider consequences) for each reactor; the problems at unit 4′s spent fuel pool were assigned a 3 (serious incident). NISA is now treating the situation as a single event, assigned a rating of 7 (major accident).

Nuclear Power: It’s Like Keeping A Dirty Bomb In Your Backyard
In the light of the current disaster still unfolding in Japan, nuclear power has been put on trial worldwide. So far the verdict is not in favor of nuclear energy, and Japan’s tragedy could be a turning point and the final political nail in the coffin of a dangerous technology. The world’s worst atomic disaster since Chernobyl in 1986 is proving hard to contain and has forced world wide debate on the benefits and dangers of nuclear energy. The fact that nuclear power plants should never be built in seismic areas shouldn’t be up for debate any longer. But other parts of the discussion over the viability of nuclear energy remain wide open. On one hand, the Green movement, with Greenpeace in the lead, argues that nuclear plants can never be made completely safe, despite improvement in design.
Why Fukushima Isn’t Like Chernobyl
Despite media hype about the radiation dangers, the Fukushima nuclear crisis won't end like Chernobyl, Alexander Sich tells The Diplomat. Is the kind of massive radiation release that occurred with Chernobyl possible at the Fukushima plant? No, it can’t have that kind of massive release. It simply can’t do that. The question is to what extent the zirconium alloy, which clads the fuel pellets, is damaged in the core, and how much of the fuel has failed.Trending catastrophe music
Are certain songs trending because people connect them mentally to recent news? If we look at the music statistics can we find a kind of soundtrack to the current world events? Please note, this post was designed to be enjoyed with a soundtrack. So before reading further, I suggest pressing play on the video below.
OSH Answers: Radiation - Quantities and Units of Ionizing Radiation
What is ionizing radiation? Ionizing radiation is radiation that has enough energy to remove electrons from atoms or molecules (groups of atoms) when it passes through or collides with some material. The loss of an electron with its negative charge causes the atom (or molecule) to become positively charged.
