About Nuclear Blast Simulator
Educational Mission
Our nuclear blast simulator serves as an educational tool to promote understanding of nuclear weapons effects and support global nuclear disarmament efforts.
By visualizing the devastating consequences of nuclear weapons, we aim to foster informed discussions about nuclear policy, arms control, and the urgent need for a nuclear-weapon-free world.
Scientific Approach
Blast Effects Modeling
Our calculations are based on declassified scientific research and the authoritative work "The Effects of Nuclear Weapons" by Glasstone & Dolan (U.S. Department of Defense).
- Fireball radius and temperature effects
- Air blast overpressure zones (20 PSI, 5 PSI, 1 PSI)
- Thermal radiation burn zones
- Radioactive fallout patterns
Air Burst vs Surface Burst
The simulator accurately models the critical differences between detonation types:
Air Burst
- • Maximum blast damage over wide area
- • Optimal for military targets
- • Minimal radioactive fallout
- • Used on Hiroshima and Nagasaki
Surface Burst
- • Reduced blast radius (40-50%)
- • Massive radioactive fallout plume
- • Ground shock and crater formation
- • Long-term area contamination
Historical Context
Since the atomic bombings of Hiroshima and Nagasaki in 1945, the world has lived under the shadow of nuclear weapons. Today, nine nations possess approximately 13,000 nuclear warheads.
Our simulator includes historical weapons from the nuclear age, from the first atomic bombs to modern thermonuclear weapons, demonstrating the exponential increase in destructive capability.
"The unleashed power of the atom has changed everything save our modes of thinking, and we thus drift toward unparalleled catastrophe." - Albert Einstein
Limitations & Disclaimers
Important Notice
This simulator provides estimates based on idealized conditions. Actual nuclear weapon effects would vary significantly based on numerous factors:
- Terrain, buildings, and geographic features
- Weather conditions and atmospheric density
- Time of day and population distribution
- Emergency response and medical infrastructure
- Weapon design variations and delivery method
This tool is for educational purposes only and must never be used for planning or targeting.
Call for Nuclear Disarmament
Knowledge of nuclear weapons effects should inspire action toward a nuclear-weapon-free world.
We support international efforts for nuclear disarmament, including the Treaty on the Prohibition of Nuclear Weapons, and organizations working toward nuclear abolition.
