That's the point, the fireball radius was a tiny fraction of that total radius, the radius you find with this formula: R = Y^(1/3)*0.28. Technically you could argue that the explosion radius was 900 km, because the shockwaves shattered windows and did minor damage as far as Norway (around Tromso).Wait, the Tsar bomb explosion is 100km
But maybe I'm mistaken about the fireball being 3.5km, I have several sources saying it was actually 8 km and that the 3.5km figure is a hypothetical. The fireball never actually touched the ground and therefore had a much bigger radius than it would have, had it exploded on the ground and not kilometers in the air. The 3.5km figure assumes contact with the ground, it was actually an 8km blast radius.
