FAQ
Common questions about how NukeSim works, what its limits are, and what kind of science the site is based on.
What science is the simulator based on?
The simulator uses public, unclassified information on nuclear weapons effects, including widely cited effects literature, scaling-law approaches, and established blast, thermal, radiation, and fallout concepts used in civil-defense and academic discussions.
Does it use exact government or classified models?
No. NukeSim does not rely on classified material. It uses educational effects modeling built from public sources and approximations intended to show scale and consequence, not to reproduce any official targeting or weapons-effects software.
Why are the results approximate?
Real outcomes depend on many local factors: burst height, terrain, weather, urban density, construction standards, sheltering, and the exact weapon design. A public educational simulator can represent the broad physics and relative scale, but not every real-world variable.
How should I interpret the casualty estimates?
They are rough illustrative estimates, not predictions. They help users understand order of magnitude and relative severity. Actual casualties would vary enormously depending on population density, time of day, evacuation, sheltering, emergency response, and infrastructure resilience.
How is fallout modeled?
The fallout display is an educational plume model that reacts to wind direction and wind speed and is meant to show downwind contamination risk and the directional nature of fallout spread. It is not a substitute for professional atmospheric dispersion modeling or emergency-response forecasting.
Why can fallout look different from blast and thermal zones?
Blast and thermal effects are primarily distance-based around the detonation point. Fallout is directional. It depends heavily on wind and on how radioactive material is lofted and carried, so its shape is more plume-like than circular.
Why do some weapons show more fallout than others?
Local fallout is strongly affected by the type of detonation and by how much radioactive material is drawn into the plume. In simplified public models, surface or lower bursts generally create more local fallout than cleaner high airbursts.
Is this site for education or advocacy?
The primary purpose is education. The site is meant to help people understand the scale, danger, and physical consequences of nuclear weapons in a way that is more immediate than reading raw numbers alone.
Can this be used for planning or operational decisions?
No. It should not be used for targeting, planning, emergency management, or any operational decision-making. NukeSim is an educational reference tool.
Why include weapons history and news on the same site?
Because people usually want three things together: what the weapon is, what it would do, and why it matters now. The arsenal, simulator, intel, and news sections serve those different questions.
