Intense thermal radiation at the hypocenter forms a nuclear fireball which, if the explosion is low enough in altitude, is often associated with a mushroom cloud. In a high-altitude burst where the density of the atmosphere is low, more energy is released as ionizing gamma radiation and X-rays than as an atmosphere-displacing shockwave.
These materials let off nuclear radiation in the form of residual radiation. [8] In the event of a nuclear attack, a human body can be irradiated by at least three processes. The first, and most significant, cause of burns is thermal radiation and not caused by ionizing radiation. Thermal burns from infrared heat radiation, these would be the ...
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Here's a sneak peak of what would happen to Times Square: The visualization relies on data from Stevens Institute of Technology professor Alex Wallerstein, who created a "Nuke Map" to measure the ...
The 2011 Fukushima Daiichi nuclear disaster, the worst nuclear incident in 25 years, displaced 50,000 households after radioactive material leaked into the air, soil and sea. [1] Radiation checks led to bans on some shipments of vegetables and fish. [2] Map of contaminated areas around the plant (22 March – 3 April).
The nuclear accident still stands as the only accident in commercial nuclear power that led to radiation-related deaths. [58] The steam explosion and fires released approximately 5200 PBq, or at least 5 percent of the reactor core, into the atmosphere. [ 58 ]
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
A map claiming to show the areas of the US that may be targeted in a nuclear war that originally circulated in 2015 is making the rounds again, amid the Russian war in Ukraine.
