That's blind faith for you.

How do they know I haven't been to the moon? That's rather presumptuous.

saw, in one of the Chicago hindu temples, a whole display that pointed out that they came up with the idea of space travel first.

wirehead, Yes and they also invented nuclear weapons too.

instructed as a wide-eyed child that the battlefield of the Mahabharata is an allegory for a large-scale nuclear war.

it could be how do you know??!

chicawhappa, Nuclear fall out lasts a looooong time.

it could be some sorta clean nuclear type weaponry? like a death ray that pulverizes everything into a hot mist...so, no fallout

it depends on the formulation. You can adjust the fallout content and neutron radiation flux up and down, within limits...

so a neutron bomb has a LOT more neutron radiation, but correspondingly less explosive blast.

or you can put a shell of cobalt or gold or tantalum or zinc around the bomb to make fallout with a particular half-life.

they did make some bombs to be "cleaner" than normal nukes, but with a reduced yield.

so it's unlikely that anybody who's going to drop a not-especially-clean "clean" nuke is going to bother with lower yield.

oh - i always thought fallout is the powder that buildings n roads n vehicles turn into from the explosion, and choke everyone to death with

the mix of the powder and the radioactive substances from the nuke bomb itself.

i saw a terrifying film called Threads from the 80s.

no, but there are plenty of opportunities for induced radioactivity in the debris, too.
