As an example, you can use the model to estimate what would happen to the largest cities in the U.S. if a nuclear bomb as powerful as the infamous "Tsar Bomba" was detonated on them.

The third most powerful test took place earlier in 1962, with a yield of 21.1 megatons. Much like the other very high-yield Soviet bomb tests, Test 147 was detonated in the air over Novaya Zemlya ...

"Modern nuclear weapons have so-called use controls, which prevent their undesired detonation," Bleek said. "For example, a missile warhead needs to experience certain conditions before it arms ...

Lebed claimed that the devices had a yield of 1 ... Examples of "suitcase nukes ... Sublette suggests that a fissile mass of around 10.1 kilograms could bring about a nuclear explosion without ...

60 years after the historic detonation, ... The detonation of the first nuclear bombs over Hiroshima and Nagasaki in August 1945 is ... test bomb's explosive yield was 50 million tons (50 ...

Does not knowing where you'd take shelter in the event of a single, low-yield (0.1-10 kilotons) nuclear detonation in a major urban area keep you awake at night? We thought so. But don't worry ...

You are in a large city that has just been subjected to a single, low-yield nuclear detonation, between 0.1 and 10 kilotons. This is much less powerful than the bomb dropped on Hiroshima — about ...

How nuclear weapon safeguards work — or fail From chains of command to complicated arming switches, this is what stops nuclear accidents from happening (so far) ...
