About NukeSim

NukeSim is a website for exploring what different nuclear weapons would do in specific locations. Users place a target pin on a map, choose a weapon, and view blast, thermal, radiation, and fallout overlays. The site is described as inspired by NUKEMAP.

The site also includes a database of active and retired nuclear weapons, a set of educational articles written by the site, and a news section that displays an RSS feed of nuclear, policy, science, and defense coverage from external sources. A legend on the homepage explains what each overlay represents, including fireball, blast rings, thermal rings, radiation rings, and fallout.
