And this- forgot about the EMP effect
At 10 Kt suitcase nuc
Everything within at least 1/3 mile or so would have been fried

And by today lethal radiation zone would be about 20 miles depending in winds

In fact, if that explosion at Tianjin been a 1 KT suitcase nuke, we wouldn't even have cellphone video--the initial fireball and its related electromagnetic pulse would have shorted out every cellphone within two miles of the explosion point. And the shockwave from the explosion would have severely damaged even well-constructed buildings up to a mile away from the explosion point.
