Napalämpövyöhyke

Napalämpövyöhyke refers to a theoretical region where the effects of a nuclear explosion, specifically the intense heat generated, would be most destructive. This zone is primarily characterized by thermal radiation, which can cause severe burns and ignite fires over a significant area. The intensity of this heat radiation decreases with distance from the detonation point, creating a gradient of thermal effects.

The concept of a napalämpövyöhyke is closely related to the overall blast radius of a nuclear weapon. However, it focuses specifically on the thermal aspect, which can be a primary cause of casualties and damage, especially in urban environments where flammable materials are abundant. The size and extent of this zone are dependent on several factors, including the yield of the nuclear weapon, the altitude of the detonation, and atmospheric conditions.

In a ground burst, the thermal pulse is more concentrated but its range may be somewhat limited by atmospheric absorption. In an airburst, the thermal radiation can travel further, potentially igniting fires at greater distances. Understanding the napalämpövyöhyke is crucial for civil defense planning and for assessing the potential impact of nuclear weapons. It highlights the immediate and widespread danger posed by the thermal energy released in such an event.
