Blast Radius

Effect radii of nuclear weapons, airburst at optimum height.

Weapon

15 kt

How these radii are computed

Scaled from 1 kt reference distances with the standard scaling laws in Glasstone & Dolan, The Effects of Nuclear Weapons (1977): blast overpressure with Y^1/3, thermal fluence about Y^0.41, fireball about Y^0.4, prompt radiation about Y^0.19. Results are within roughly 10–20 % of published figures for a clear day, flat terrain and the height of burst that maximises 5 psi. Fallout, terrain shielding and weather are not modelled.
