Sentences with phrase «kiloton bomb»

The 2006 explosion was relatively small, releasing energy equivalent to about 1,000 tons of TNT — a fraction of the 15 - kiloton bomb dropped by the United States on Hiroshima, Japan, in 1945.

Allison has posted the grim answer on his Web site (www.nuclearterror.org), which shows a three - color «blast map» depicting the effects of a 10 - kiloton bomb, about the smallest a workable nuclear device could be.

Thomas Cochran, senior scientist at the NRDC and one of the report's authors, says a 1 - kiloton bomb could be made with as little as 1 kilogram of plutonium from designs developed by American weapons researchers in the 1950s and described in technical reports that are no longer classified.

Not exact matches

For a 10 - kiloton blast — equivalent to two - thirds of the Hiroshima bomb blast, or 5,000 Oklahoma City truck bombings — that's about a half - mile radius.

However, it's not unlikely when looking at weapons like the new B61 - 12 gravity bomb, which is built by the US, maxes out at 50 kilotons, and can be dialed down to 0.3 kilotons.

The recently tested bomb is estimated to have an explosive yield of 120 kilotons, which equates to a blast created from 265 million pounds worth of TNT, according to Norsar, a Norwegian geoscience research foundation.

As Franz - Stefan Gady at The Diplomat points out, this means that the Knyaz Vladimir «will be capable of launching 96 - 200 hypersonic, independently maneuverable warheads, yielding 100 - 150 kilotons apiece,» meaning each warhead alone is ten times more powerful than the bomb dropped on Hiroshima.

This alarms North Korea's adversaries because the nation recently detonated a thermonuclear device that yielded the energy of perhaps 300 kilotons of TNT — about 20 times as much as the bomb the US detonated over Hiroshima in 1945.

It features a «dial - a-yield» capability - setting the weapons to deliver as much as 340 kilotons (depending on the version), about 20 times the power of the bomb that destroyed Nagasaki.

On the other hand, estimates put the North Korean alleged H - bomb detonation in just six kilotons, a poorer result than the 2013 atomic test.

This is nearly half of the energy released by the bomb dropped on Nagasaki (20 kilotons) and 2/3 of Hiroshima's (15 kilotons) power.

Other physicists, including Nobel laureate Sheldon Glashow of Harvard University in Cambridge, Massachusetts, calculated that strange quark particles would dash through Earth with dramatic effect: a 1 - ton fleck would unleash the energy of a 50 - kiloton nuclear bomb, spread along its entire threadlike path.

The 1945 Hiroshima bomb was about 15 kilotons.

As the bomb exploded with an energy equivalent to 20 kilotons of TNT, the sand underneath it melted, producing a thin sheet of mostly green glass, dubbed trinitite.
