![]() ![]() It uses data from the Oak Ridge National Laboratory (which is sponsored by the US Department of Energy) that shows how many people are likely to inhabit an area within a 24-hour period. For instance, it doesn't take into account weather conditions, which can affect the altitude of a mushroom cloud and the fallout. It comes with some important limitations. But it provides "a realistic understanding of what nuclear weapons can and can't do," Nuclear-weapons historian Alex Wellerstein, who created the tool, previously told Insider. The tool is not meant to be seen as a precise map of what could definitely happen after an impact since nuclear attacks are difficult to model. The tool, which can be found here, allows you to input the city and the yield of the nuclear weapon you'd like to simulate. Orange: Thermal radiation (1.18-mile radius) - People caught within this radius could experience third-degree burns, severe scarring, or disablement. There would likely also be widespread injuries and fatalities within this radius. Wellerstein estimated that between 50% and 90% of people within this radius could die from the acute effects of radiation.īlue-gray: Air blast (1.04-mile radius) - Air blasts are powerful enough to topple residential buildings. Nuclear fallout can cause radiation poisoning, which damages the body's cells and prove fatal. Atom bombs of the type used at Hiroshima and Nagasaki represented an. Green: Radiation (0.74-mile radius) - Within at least 15 minutes of a blast, clouds of dust and sandlike radioactive particles - what's referred to as nuclear fallout - would reach the ground. Quantitatively, nuclear weapons are vastly more powerful than conventional weapons. Any buildings, objects, and people caught within this radius would likely burst into flames. Following a firebombing campaign that destroyed many Japanese cities, the Allies prepared for a costly invasion of Japan. The two events are the only use of nuclear weapons in war to date. Yellow: Fireball (590-foot radius) - Less than one-millionth of one second after a bomb exploded, it would emit a giant orange fireball filled with hot air and weapon debris. The atomic bombings of the cities of Hiroshima and Nagasaki in Japan were conducted by the United States during the final stages of World War II in 1945. Nukemap 2.5/Alex Wellerstein/Google Maps/Business Insider Core: made of metallic plutonium-239 or uranium-235, the most widely used fissile isotopes, so-called because of their natural property to split, or fission.
