🟡 Thermal radiation radius (3rd degree burns): 73.7 km (17,080 km²)

Third degree burns extend throughout the layers of skin, and are often painless because they destroy the pain nerves. They can cause severe scarring or disablement, and can require amputation. 100% probability for 3rd degree burns at this yield is 13.9 cal/cm².

Hope the air raid sirens are working then 😉

That yellow ring represents a 100% probability of 3rd degree burns. Aside from being in a nuclear bunker underground, I have no idea what kind of cover will protect someone from that kind of injury.

For third degree burns from thermal radiation you need line of sight to the explosion. Since basically all strategic nukes are airbursts, that means if you can see the sky, you're fucked. But a sufficiently thick wall or a basement would probably spare you the worst of it

Ah, so the 3rd degree burns will come from light, not air temperature?

Yes, mainly. That's also the reasons why you get silhouettes of people and objects cast on concrete

The radiation is so hot that it absolutely wrecks the surface, vaporizing or charring paint and skin near the epicenter, and causing burns and blindness further out, but so short that the heat doesn't even have time to heat up the air to any meaningful amount, outside of the blast radius itself.
