How much energy is released by a nuclear bomb?

The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons (500 kilotons) of TNT (4.2 to 2.1×106 GJ). All fission reactions generate fission products, the remains of the split atomic nuclei.

How much energy is in a nuclear bomb?

That bomb had an explosive yield of about 18 kilotons of TNT; and one kiloton of TNT is equivalent to one trillion Joules (10^12 J) of energy.

How much energy does an atomic bomb release in joules?

The atomic bomb exploded over Hiroshima released about 1.5×1013 joules of energy. How many Hiroshima bombs would one have to explode simultaneously to equal the amount of energy released in a single magnitude 8.5 earthquake?

How much mass is converted to energy in a nuclear bomb?

The strength of a nuclear explosion is measured by the amount of TNT that would produce approximately the same energy release. A megaton (million tons of TNT equivalent) is defined to be 4.2*1015 Joules, which (using E – mc2) means that about 47 grams of mass has been converted to blast and radiation.

How much energy was released by the largest atomic bomb?

The most powerful American bomb known as “Castle/Bravo”was detonated on February 28, 1954 and released energy equivalent to an astounding 15 megatons or 84,000 terajoules!

Is Hiroshima still radioactive?

The radiation in Hiroshima and Nagasaki today is on a par with the extremely low levels of background radiation (natural radioactivity) present anywhere on Earth. It has no effect on human bodies. … Most of those exposed to direct radiation within a one-kilometer radius died. Residual radiation was emitted later.

How much damage can 1 kg of TNT do?

Under controlled conditions one kilogram of TNT can destroy (or even obliterate) a small vehicle. The approximate radiant heat energy released during 3-phase, 600 V, 100 kA arcing fault in a 0.5 m × 0.5 m × 0.5 m (20 in × 20 in × 20 in) compartment within a 1-second period.

How much TNT is in a grenade?

The original Mk 2 grenade had a 3⁄8-inch (9.5 mm) threaded plug in its base, which covered the opening used to place the explosive filling, either 1.85 oz (52 g) of TNT, 2.33 oz (66 g) of Trojan explosive (a mixture of 40% nitrostarch, ammonium nitrate, and sodium nitrate), 1.85 oz (52 g) of a 50/50 amatol/nitrostarch …

How much uranium is actually exploded?

When it exploded, about 99 percent of the uranium that was supposed to undergo this chain reaction, didn’t. It just blew apart in the air, and a very small percentage, maybe two percent of the fissile material, actually detonated. And most of it just became other radioactive elements.

How much uranium is in a nuke?

Most of the uranium used in current nuclear weapons is approximately 93.5 percent enriched uranium-235. Nuclear weapons typically contain 93 percent or more plutonium-239, less than 7 percent plutonium-240, and very small quantities of other plutonium isotopes.
