Nuclear Blast Effects on a Hypothetically Invulnerable Person
Nuclear ground zero physics: blast launches objects at 350+ mph, radiation comes in three phases, and irradiation differs from contamination — an invulnerable survivor would become a contaminated biohazard.
A thought experiment: what would happen to a physically invulnerable person at ground zero of a nuclear detonation? Blast wave: The person would be launched hundreds of meters to approximately 1 km, accelerated to 350+ mph by the blast wave and supersonic winds. Radiation at detonation comes in three phases: 1. Prompt radiation: delivered in microseconds at the moment of detonation 2. Thermal heat pulse: arrives in the first second, with plasma temperatures of 1,600-8,000°C 3. Fallout: radioactive debris settling over hours to days Key distinction — irradiation vs contamination: being irradiated (exposed to radiation) does NOT make a person radioactive. Contamination (radioactive particles deposited on or in the body) does. An invulnerable survivor at ground zero would likely become contaminated with activated materials, creating a biohazard. Neutron activation: the blast makes nearby materials temporarily radioactive through neutron bombardment. This is the mechanism explored in Hunter x Hunter's Dirty Rose bomb — a nuclear device combined with a contagious poison that turns the invulnerable survivor into a walking biohazard, creating a dilemma that raw durability cannot solve.
