The half-life of the radioactive cobalt produced is about 5 years, which is long enough to give the fallout plenty of time to settle before it decays and kills, but short enough to produce intense radiation for a lot longer than you'd last in a fallout shelter.23-Nov-2015
How long would a cobalt bomb last?
If the cobalt bomb reaches its destination, it will impact the ground and detonate, rendering the entire nation under complete cooldown and unable to do anything for a full 60 seconds.
How long does a nuclear bomb last?
Calculations demonstrate that one megaton of fission, typical of a two-megaton H-bomb, will create enough beta radiation to blackout an area 400 kilometres (250 mi) across for five minutes. Careful selection of the burst altitudes and locations can produce an extremely effective radar-blanking effect.
How much would a cobalt bomb destroy?
Theoretically, a device containing 510 metric tons of Co-59 can spread 1 g of the material to each square km of the Earth's surface (510,000,000 km2).
What would a cobalt bomb do?
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.
What is the most powerful bomb?
Tsar Bomba Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
Has a cobalt bomb ever been used?
As far as is publicly known, no cobalt bombs have ever been built. The Operation Antler/Round 1 test by the British at the Tadje site in the Maralinga range in Australia on September 14, 1957 tested a bomb using cobalt pellets as a radiochemical tracer for estimating yield.
What is the blast radius of a nuke in miles?
The initial radiation pulse from a 1 KT device could cause 50% mortality from radiation exposure, to individuals, without immediate medical intervention, within an approximate ½ mile (790 m) radius. This radius increases to approximately ¾ mile (1200m) for a 10 KT detonation.
How far away from a nuke is safe?
Heat is the prime concern for those closer to a nuclear blast, with people up to 6.8 miles away suffering first-degree burns and third-degree burns hitting anyone up to 5 miles away. You've got to consider the immense thermal radiation too, which travels at the speed of light.
What would happen if a cobalt bomb exploded?
When the bomb explodes, the neutrons produced by the explosion would transmute the cobalt to the radioactive isotope cobalt-60 (60Co), which would be vaporized by the explosion. The cobalt would then condense and fall back to Earth with the dust and debris from the explosion, contaminating the ground.
