The likelihood of a nuclear catastrophe in Manhattan is quite small. NYC has highly sensitive radiation detection devices at all imaginable access points into the city - bridges, tunnels, airports, and seaports. Additionally, there are unmarked vans with highly sensitive radiation detecting equipment that cruise the city streets. The only way a nuclear weapon could enter the city or be detonated in the city would be through an air strike. If this were to happen, the nuclear epicenter could be approximately 2 kilometers in circumference. Anyone in this epicenter will be instantly incinerated from the heat. Outside of this area, the shock wave will likely kill everyone through the massive physical destruction of the city infrastructure, but for those who survive the shock wave, there may have a chance. All radioactive fallout (exposure) must be avoided by moving "into the wind" such that the debris falls behind you - so it is essent ... Read More
