To my Kids #4 types of nuclear attack

 

All the following nuclear events can be a dangerous.

Dirty radioactive DYI bomb. Here one packs used radioactive material around regular explosives.  Can spread radioactive debris over the blast radius (a few hundred yards most likely).  

Low altitude small nuclear bomb say 10 miles above the earth.  Could burn out over 50%  of electric devices several hundred miles under its blast. This includes many autos, planes, cell phones, computers and area power grids, etc for several Months.  

Atomic bomb in truck or ship properly detonated. Depending on its kilotons will destroy or set on fire and thing with a few miles to several min.  People and stick buildings would catch fire if near ground zero.  If in a basement or inter windowless room in a solid brick building not at ground zero have a chance of surviving the initial blast and fire storm.  Outside exposure outside ground zero can kill instantly or take up to several weeks or years. Down range fall out for a few weeks can cause death in a few weeks or years depending.  As a general rule after 7 to 14 days you can go outside again and or when your local authorities say to can.

I do not see a total nuclear war with an all out nuclear exchange.  I see a possibility of a few tactical nuclear weapons and or a very limited ICBM or SLBMs strike as a worse case.
