## What is the smallest explosion?

The SADM (the brass-looking cylinder above) is a variable yield, portable nuclear demolition charge that can be set to a yield of between 10 tons and one thousand tons.

That depends on how powerful the bomb is, just like conventional explosives..

## What is the blast radius of a modern nuclear bomb?

In a typical air burst, where the blast range is maximized to produce the greatest range of severe damage, i.e. the greatest range that ~10 psi (69 kPa) of pressure is extended over, is a GR/ground range of 0.4 km for 1 kiloton (kt) of TNT yield; 1.9 km for 100 kt; and 8.6 km for 10 megatons (Mt) of TNT.

## Is there a limit to the size of a nuclear bomb?

There is a physical limit about the megatons of the nuke? The only limit to the size of a thermonuclear bomb, meaning one whose yield is driven in large part because fusion is occurring due to high temperatures and pressures, is given by nature. … It is somewhere between 2.4*10^28, and 4.8*10^28 megatons.

## How heavy is a nuclear warhead?

Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ).

## What is the smallest hydrogen bomb?

The smallest hydrogen bomb ever known to have been tested had a yield of least about 30 kilotons (kT is a unit of measuring the energy of explosion as an equivalent in thousands of tons of TNT). For reference, the atomic bomb detonated over Nagasaki in 1945 that killed about 40,000 people instantly, was 21 kT.

## How many mini nukes are in Fallout 4?

When found, they will contain either 3 or 4 mini nukes, depending on the player character’s Scrounger perk rank. There is also a mini nuke melee weapon. It can only be acquired by using the console (PC) to either add it to the inventory (player.

## Is there a cobalt bomb?

A cobalt bomb is a type of “salted bomb”: a nuclear weapon designed to produce enhanced amounts of radioactive fallout, intended to contaminate a large area with radioactive material. The concept of a cobalt bomb was originally described in a radio program by physicist Leó Szilárd on February 26, 1950.

## How small can a nuclear bomb be made?

Extremely small (as small as 5 inches (13 cm) diameter and 24.4 inches (62 cm) long) linear implosion type weapons, which might conceivably fit in a large briefcase or typical suitcase, have been tested, but the lightest of those are nearly 100 pounds (45 kg) and had a maximum yield of only 0.19 kiloton (the Swift …

## Are mini nukes possible?

Yes, the mini-nuke launcher was a thing and yes, it was a terrible idea. … In the late 1950s, when the threat of nuclear war with the Soviets was lurking around the corner, the U.S. actually created a functioning mini-nuke launcher of their very own.

## Is a hydrogen bomb a nuclear bomb?

Thermonuclear bomb, also called hydrogen bomb, or H-bomb, weapon whose enormous explosive power results from an uncontrolled self-sustaining chain reaction in which isotopes of hydrogen combine under extremely high temperatures to form helium in a process known as nuclear fusion.

## What is the blast radius of a 50 megaton bomb?

2.3 kmThe Soviet Union built the largest thermonuclear bomb in human history. The name of the bomb was Tsar Bomba. It had a yield of 50 megatons of TNT. Fireball radius was 2.3 km or covering 16.61 square kilometers.

## How would you survive a nuclear bomb?

“Get inside, stay inside, and stay tuned. If you can get into a basement, that’s even better.” Being indoors during the blast will help, but if you are outside for any part of the detonation, it’s important to minimize the amount of fallout you absorb once you’re safe inside.

## Has a tactical nuke been used?

It quickly became obsolete and was withdrawn from service in the 1960s. Other tactical nuclear weapons were meant to be carried by U.S. troops behind enemy lines, such as the B-54 Special Atomic Demolition Munition, which could fit in a backpack.

## What is the smallest nuclear bomb?

Davy Crockett bombKnown as the “Davy Crockett bomb,” America’s smallest-ever nuclear weapon packed a relatively small punch when compared to its larger cousins — between a 10 and 250-kiloton yield.

## What is the biggest nuke in the world?

Tsar BombaThe nuclear arms race that originated in the race for atomic weapons during World War II reached a culminating point on October 30, 1961, with the detonation of the Tsar Bomba, the largest and most powerful nuclear weapon ever constructed.

## What country has the most nuclear weapons?

Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. … In fact, nearly all the induced radioactivity decayed within a few days of the explosions.

## Can we nuke the moon?

The study found the Moon’s orbit would be unchanged (Kurzgesagt says a nuke would move the Moon as much as somebody blowing air would move a truck), and it would simply be left with another crater on its surface. … There would also be radioactive debris on the Moon’s surface.

## How many tons of TNT is a nuke?

1,000,000 tonsFor example, the atomic bomb dropped on Hiroshima, Japan, in 1945, containing only about 64 kg (140 pounds) of highly enriched uranium, released energy equaling about 15 kilotons… … contrast, is frequently expressed in megatons, each unit of which equals the explosive force of 1,000,000 tons of TNT.

## How big is a tactical nuke?

Tactical (nonstrategic) nuclear weapons (TNWs) typically refer to short-range weapons, including land-based missiles with a range of less than 500 km (about 300 miles) and air- and sea-launched weapons with a range of less than 600 km (about 400 miles).
