Blast Radius 3D
Blast Radius 3D is a free, educational nuclear explosion simulator. Pick any place on a 3D map,
choose a weapon from Little Boy to the Tsar Bomba, and watch the fireball, blast wave, thermal
radiation, mushroom cloud and fallout plume drawn to scale over real city buildings, with a
casualty estimate from open population data.
