Ground Zero
Have you ever wondered what would happen if a nuclear bomb goes off in your city? With Google's Maps framework and a bit of Javascript, you can see the outcome. And it does not look good. Search Usage Just enter the address of that boss, teacher, colleague or loved one. If you can find it in Google Maps, you can nuke it.

We now have Ground Zero II - with more bombs and countries, it maps the radioactive fallout from an atomic explosion. Just click here to see it. About Weapons and Countries (29January2009) The list of weapons contains bombs of historical significance - but what happens with modern, nuclear-assertive countries not in the list?

Governor: 6 tanks leaking radioactive waste at Washington nuclear site The Hanford site in southeast Washington state once played a major part in U.S. plutonium production. Last week, Washington's governor said 1 tank at the Hanford nuclear site was leakingHe now says 6 tanks are leaking radioactive waste, calling the news "disturbing"The leaks pose "no immediate health risks," but do pose concerns, the governor saysHanford site is home to one of the world's largest nuclear cleanup efforts (CNN) -- Six tanks at the Hanford Nuclear Reservation in southeast Washington state are leaking radioactive waste, the governor said Friday, calling the news "disturbing" even as he insisted there are "no immediate health risks." "News of six leaking tanks at Hanford raises serious questions about integrity of all single tanks," Gov. Inslee said that he got the latest information about the site during a meeting in Washington with U.S. On Friday, Inslee said there is "still no current health risk" tied to the leaks. CNN's Carma Hassan contributed to this report.

The Atomic Bombings of Hiroshima and Nagasaki The Atomic Bombings of Hiroshima and Nagasaki : Chapter 10 - Total Casualties There has been great difficulty in estimating the total casualties in the Japanese cities as a result of the atomic bombing. The extensive destruction of civil installations (hospitals, fire and police department, and government agencies) the state of utter confusion immediately following the explosion, as well as the uncertainty regarding the actual population before the bombing, contribute to the difficulty of making estimates of casualties. The Japanese periodic censuses are not complete. Finally, the great fires that raged in each city totally consumed many bodies. The number of total casualties has been estimated at various times since the bombings with wide discrepancies. The relation of total casualties to distance from X, the center of damage and point directly under the air-burst explosion of the bomb, is of great importance in evaluating the casualty-producing effect of the bombs.

Destructive Effects Counting the Dead Chaotic conditions made accurate accounts most difficult. Some victims were vaporized instantly, many survivors were horribly disfigured, and death from radiation was uncertain—it might not claim its victims for days, weeks, months, or even years. The initial death count in Hiroshima, set at 42,000–93,000, was based solely on the disposal of bodies, and was thus much too low. Additional counts indicated high levels of short-term mortality in both cities: —Over 90% of persons within 500 meters (1,600 ft.) of ground zero in both cities died. Most persons close to ground zero who received high radiation dosages died immediately or during the first day. While casualty rates exceeded death rates, they both were highest near ground zero and declined at similar rates by increasing distance from ground zero. *Figure 11. *Figure 12.

Copy and paste the following to mashup the Ground Zero II script into your own website or blog: A ZIP archive with the source code can be found here. Science Caveat The damage caused by a nuclear explosion is affected by a multitude of variables, and some of these require powerful super-computers to be simulated properly. Fallout shows the possible dispersion of radioactive isotopes after six hours of the explosion, assuming a constant gentle breeze. Project: 200903A

Who holds the world's nuclear warheads? Get the full list by country | News The news that North Korea has successfully launched a satellite heightened fears that the same know-how could be used to launch ballistic missiles. Which countries already have the capability to launch a nuclear missile, and how many warheads do they have? Data on the number of nuclear weapons is notoriously difficult to find - not least because commitments on disarmament and dismantlement are linked to the number of weapons each state has claimed to have. Among the few reliable statistical sources is the Bulletin of the Atomic Scientists. Their latest report shows that Russia and the United States remain far ahead of the rest of the P5 (the five permanent members of the UN Security Council: the US, Russia, China, France and the UK). Russia currently has around 4,650 active warheads in its stockpile and approximately 7,350 in reserve or awaiting dismantlement. Estimates suggest that the United States now has 2,150 active warheads compared to 31,255 in 1967. Download the data NEW!

Chernobyl: Capping a Catastrophe The Chernobyl accident can be likened to a huge dirty bomb, an explosion that spewed radioactive material in all directions. The blast was followed by a fire that sent even more contaminants into the atmosphere that were then carried by winds across the region and into Western Europe. In this way the disaster differs from nuclear power’s two other major accidents, at Three Mile Island in Pennsylvania in 1979 and Fukushima in 2011. At both of those plants, reactor cores melted down, but the core material — the nuclear fuel — remained within protective containment structures. The four reactors at the Chernobyl plant had no such containment. That is what happened in the early hours of April 26, 1986, at Chernobyl’s Unit 4, during an ill-advised test of some of the reactor’s safety systems. Officially, several dozen people were killed, and many others became sick. Inside the Reactor That was nearly three decades ago. From time to time, new evidence of the disaster emerges.

Inside the sarcophagus | The Chernobyl Gallery The sarcophagus that currently encases Unit 4 of the Chernobyl Nuclear Power Plant is a giant metal concrete and structure quickly constructed as an emergency measure in 1986 to halt the release of radiation into the atmosphere following the explosion. The official Russian name is “Obyekt Ukrytiye” which means shelter or covering. It is estimated that within the shelter there is 200 tons of radioactive corium, 30 tons of contaminated dust and 16 tons of uranium and plutonium (source Wikipedia). Cross section of the sarcophagus over reactor 4 Reactor 4 following the explosion The enormity of the challenge ahead is clear. Construction of the sarcophagus The sarcophagus was constructed under extremely dangerous conditions, with very high levels of radiation, and severe time constraints. More than 400,000 m3 of concrete and 7,300 tons of metal framework were used during construction with the building ultimately enclosing 740,000 m3 of heavily contaminated debris and soil inside.

Please enter a valid email address and try again! No thanks Japan: Was the Fukushima Meltdown All That Dangerous? The headlines were extraordinary: “Japan Weighed Evacuating Tokyo in Nuclear Crisis,” the New York Times wrote a few days ago. “Tokyo Evacuation ‘Was Considered’,” said the Sydney Morning Herald. “Japan Urged Calm While It Mulled Tokyo Evacuation,” wrote … hey, TIME magazine. The stories detailed the Rebuild Japan report, a deep and independent investigation of the events surrounding the Fukushima nuclear meltdown that occurred nearly a year ago. Considering that some 30 million people live in the vast metropolitan area of Tokyo — about a quarter of Japan’s total population — the idea of evacuating the capital city is, frankly, unimaginable. (MORE: Japan, One Year Later) There are some dissenting voices. Yet there’s something about nuclear power that seems to make the media and others go straight to the worst-case scenario — without pausing to evaluate how likely it really is.
