For a high-yield weapon, the radius within which ignitions are likely to occur can stretch 3 to 5 miles, depending on atmospheric conditions and the specific design of the bomb. Yield (Kilotons) Severe Blast Radius (Miles) Moderate Blast Radius (Miles) 10 KT 0.

The destructive footprint of such an event is not a single point but a layered series of zones, each with distinct levels of intensity. A ground burst creates a massive fireball and intense local fallout, while an airburst maximizes the blast wave range by allowing the shockwave to travel further through the denser lower atmosphere without being disrupted by the ground.
Calculating the Fireball and Thermal Radiation Reach While the blast wave is a primary concern, the thermal radiation poses a significant threat that extends the overall radius of impact. This lingering threat can render regions uninhabitable for years, expanding the long-term danger zone far beyond the physical blast radius.

The scale of modern arsenals means that a single detonation over a major metropolitan area could impact an entire region, making the distinction between tactical and strategic weapons largely a matter of scale rather than existence. For a 1-megaton airburst, this lethal overpressure zone can extend approximately 2 to 3 miles from the hypocenter.
