The Real Mother of All Bombs, 46 Years Ago 526
vaporland writes "Tsar Bomba is the Western name for the RDS-220, the largest, most powerful weapon ever detonated. The bomb was tested on October 30, 1961, in an archipelago in the Arctic Sea. Developed by the Soviet Union, the bomb had a yield of about 50 megatons. Its detonation released energy equivalent to approximately 1% of the power output of the Sun for 39 nanoseconds of its detonation. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout. The Tsar Bomba qualifies as the single most powerful device ever utilized throughout the history of humanity."

In September 1940, the Japanese Army controlled Institute of Physical and Chemical Research, or Rikken, was assigned a preliminary project. In 1942, the Japanese Navy began also (somewhat independently of the Army) working on a Uranium based fission device. The project was called F-Go {or sometimes just No. F, for fission]. This was located at Kyoto, and was actually the chief reason why Kyoto was added to the list of potential military targets for the U.S. bombs, although in the end the city was still taken off the list by Truman due to its historic and social value. Despite a certain military commitment these programs weren't backed with adequate resources, and the Japanese were probably still four or more years from having a bomb by the end of the war.
A Japanese plant, concealed in Hungnam, now part of North Korea, may have been the source of heavy water subsequently used by the USSR for its own bomb research. There are reports the Soviet Union continued to run that plant and collected the output every other month by submarine, and it alone may have shaved a year or more off the USSR's development time.
In May 1945, a German submarine which surrendered to US forces , was found to be carrying over 500 kg. of Uranium oxide destined for Japan. The oxide contained about 3.5 kilograms of isotope U-235. While not enough to make a bomb, that was a sizable fraction of one. After the Japanese surrender, the occupying US Army found five cyclotrons which were capable of separating fissionable material from ordinary uranium. The US bomb program was accomplished by using gaseous diffusion based separation, but cyclotronic separation was rejected not because it wouldn't work, but because it seemed likely to take longer. Some historians see the willingness of the Germans to supply Uranium to their ally as proof they didn't fully appreciate the potential, while Japan did.
Re:I respectfully disagree... (Score:5, Interesting)
The bigger problem was that an impurity in graphite during research caused German scientists to miscalculate the amount of uranium needed to have a sustainable fission reaction, causing them to estimate it at many hundreds of tons, rather than the small pounds that the Americans ultimately came up with.

Writing = civilization? While there's an obvious correlation, not quite. All the Germanic tribes by the fall of Rome had adopted scripts of their own. Anyway the judgment obviously had a lot more to do with 19th century ethos than anything else.
Christianity was employed against the enemy - Rome pursued a policy of converting Germanic tribes to a Rome-centered Christianity, to make them more dependent towards Rome. So in that sense, Christianity probably prolonged the empire.

He had headed a small lab elsewhere at MIT as a principal investigator, but he signed on to our project as an engineer because research money had dried up. He brought with him this odd stainless steel apparatus that looked like a mutated, high tech water main. We were using it as small vacuum tank. I asked him what the thing was built to do, and he told me that it was a new kind of electron microscope he had invented that could make images showing the distribution of the different kinds of atomic nuclei in the thing being imaged.
"Wow, that's very interesting," I said.
"It is," he replied, "but it was funded on an ONR grant, and they're not funding that kind of research any more. Back in the old days," he went on, "I'd have told them it was a death ray. It's all those damned ROTC engineering grads," he sighed. "About the only way you could kill somebody with this is to drop it on him from a high place. Those guys aren't physicists, but they know a death ray when they see one. All they want to talk about is deaths per dollar."
The deaths per dollar metric fascinated me. Later I brought it up with some of my friends back at the dorm, and we kicked around the question of how various methods of manslaughter stacked up. The idea of blowing up the famous "Corita" LNG tanks near Boston was popular, until we fetched some Chem E majors who told us about the eight hundred reasons that you couldn't kill more than a handful of people that way.
Finally, I hit upon an unbeatable method when it comes to deaths per dollar. Go to a construction site, and root through the dumpster until you get a nice section of 2x4 about five feet long. Then walk down the street and beat everybody you meet to death with it.
"But," they protested, "that's assuming that your time is free."

You got that right. This is why modern weapons don't even go above one megaton. Instead you load multiple warheads that are "only" a few hundred kilotons into a single missile. Of course, this is pretty much overkill as well, because quite frankly, a "small" number of warheads will be quite sufficient as a deterrent. The chance that somebody will attack you if they know they will get 50 nukes flying right back at them is not very much greater than if they are going to get 400 nukes back in their face. Now, to put this into perspective, the US has more than 5000 warheads in service, and more than 9000 stockpiled. Russia has close to 6000 in service, and 16000 stockpiled. The UK has 750 in service, France has 350, and China some 130. India has about 80, Pakistan about 10, and Israel is suspected to have between 100-300.
Thus in total there are some 10.000 warheads in service in the world, which works out to about 100 nukes per country. As anybody with half a brain can see, this is absolutely silly. The larger nuclear powers could cut their arsenals by a factor of 10, and they would still have several hundred nukes in service as a deterrent.

No, ICBMs couldn't carry it either. By far not. The R9 [wikipedia.org], which just came into production in 61, could carry less than 2 tons.
The idea behind the Tsar (besides proving who has the biggest) was to compensate for inaccurate targeting. The goal was a bomb that could level a town even if dropped miles away (because the bomber was about to be shot down, or because the pilot had better things to do, like avoiding being shot down, than aiming accurately). It was quickly abandoned when ICBM targeting became accurate enough to ensure you could level whatever target you want to strike. And MIRVs offer much more destruction per ton carried.

I repeat: 39ns is just the period of time that the power level peaked for. They calculated that the amplitude of the power peak itself, was equivalent to 1% the power output of the sun.
We don't care about how long the peak lasted for, the 39ns, unless you start integrating power over time as you just did, in which case you're comparing a quantity of energy, rather than a rate of energy output. Yes, I suppose you could say that 39ns @ 1% sun power is equivalent to an amount of energy produced by the sun in 0.39ns, but that's not the interesting number here, because we could similarly integrate just about any huge power source over a long enough interval of time (hours, days, years, whatever) to come up with "the same amount of energy output by the sun over 39 ns".
So the interesting number is in this case, yes, that the actual instantaneous absolute power output of the bomb approached 1% of that of the sun, albeit for only 39 ns.

The fusion reaction produces a neutron or so for each helium atom created. In a conventional hydrogen bomb, these neutrons are used directly to cause damage, by irradiating living things. But in a Cobalt bomb...
The neutrons are absorbed by the Cobalt, to become the highly radioactive gamma ray emmitter Cobalt-60. It gets vaporized by the blast, and largely blown into the upper atmosphere.
Most radioactive fallout from an H-bomb has a very short half life, which is why those who escape the blast can safely emerge from their fallout shelters in a couple weeks. Not so with Cobalt-60: it has a half-life of several years.
That's long enough to enable to vaporized Cobalt-60 to spread via air currents all over the Earth, eventually to be caught up in raindrops and thereby fallen to the Earth.
Where it will irradiate everyone with a lethal gamma dose.
It was envisioned as a spoiler, to be detonated by the loser in a nuclear war. It would need to be a pretty big bomb, on the scale of Tsar Bomba, but it wouldn't need to be delivered, just detonated in place.
