Nuclear Detonation Briefing Products address the same near-term and longer-term actionable decisions as the Radiological Dispersal Device (RDD) Briefing Products — evacuation or sheltering, long-term relocation of the population, emergency worker safety, and contamination of agricultural crops. Additional Nuclear Detonation Briefing Products show the damage to structures and the casualties resulting from the overpressure, thermal radiation, and ionizing radiation produced by the nuclear detonation.
Dose levels resulting from a nuclear detonation change rapidly due to the initial build-up of fallout and the fast decay of some of the nuclear fission products. Time series plots illustrate the changing dose level areas during the first hours and days following the detonation.
