There’s a lot of “missing” Russian suitcase nukes. I have no idea what force they have.
Fires don’t set off nukes.
Still, IAEA may just be using the “Crisis” to get a look around.
The smallest is about 10-12 kilotons. This was 24 tons.
Big difference.
From http://nuclearsecrecy.com/nukemap/
Effects radii for 3 kiloton surface burst (smallest to largest):
Fireball radius: 120 m (0.05 km²)
Air blast radius (20 psi): 310 m (0.31 km²)
At 20 psi overpressure, heavily built concrete buildings are severely damaged or demolished; fatalities approach 100%. Air blast radius (5 psi): 0.66 km (1.37 km²)
At 5 psi overpressure, most residential buildings collapse, injuries are universal, fatalities are widespread.
