For high altitude nuclear explosions, these electrons are captured in the Earth's magnetic field at altitudes between 20 and 40 kilometers where they interact with the Earth's magnetic field to produce a coherent nuclear electromagnetic pulse (NEMP) which lasts about one millisecond. Secondary effects may last for more than a second.
Nuclear fallout is residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. [1] It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a ...
A government safety expert says its entirely possible to survive a nuclear explosion and its aftereffects. ... (Several miles away, radiation dosage drops to tens of millisieverts or less for ...
The main causes of death and disablement in this state are thermal burns and the failure of structures resulting from the blast effect. Injury from the pressure wave is minimal in contrast because the human body can survive up to 2 bar (30 psi) while most buildings can withstand only a 0.8 bar (12 psi) blast.
The scenario assumes a terrorist-caused nuclear blast of about 10 kilotons' worth of TNT or less. Few people would survive within the immediate damage zone, which may extend up to one or two miles ...
The Cold War ended in 1991, but the looming threat of nuclear attack lives on with more than 14,900 nuclear weapons wielded by nine nations.. A terrorist-caused nuclear detonation is one of 15 ...
Larger wildlife didn't fare much better. Although most livestock were relocated a safe distance away, horses and cattle located on an isolated island 6 km away from the Chernobyl radioactivity were not spared. [9] Hyperthyroidism, stunted growth, and, of course, death plagued the animals left on the island. [9]
The first thing you'd see if a nuclear bomb exploded nearby is a flood of light so bright, you may think the sun blew up -- but don't try to drive away. If a nuclear bomb explodes nearby, here's ...
