Thermal Radiation and Ignition Radius How big is a nuke radius when considering heat rather than pressure? The thermal radiation radius extends much further than the blast wave. 5 to 1 mile from the hypocenter for a 10-kiloton device.
How Big Is a 10kt Blast Radius: Understanding the Impact Zone
The exact size fluctuates based on the height of the explosion and the type of weapon used. Understanding how big a nuke radius is requires looking at specific overpressure levels that define distinct damage regions.
The Moderate to Light Damage Zones Expanding outward, the moderate damage zone experiences overpressure between 5 and 20 PSI, which can shatter windows, damage walls, and cause serious injuries from flying debris. For a 10-kiloton explosion, shattered glass can be found up to 3 miles away, causing injuries to people indoors who survive the initial blast.

Firestorm and Secondary Effects In urban areas, the combination of blast damage and thermal radiation can create a firestorm, where the resulting fire creates its own weather system. While the immediate blast and thermal effects fade, the contamination zone poses a long-term threat, rendering areas uninhabitable for days, months, or years after the detonation.
