Only by being a safe distance away.
none
A direct nuclear blast - nothing. However it is said that cockroaches would possibly survive radiation where other animals would be killed.
Twinkies
only by being far far away
Not within the 5 PSI max overpressure range.
Anyone that has not been kiled in the blast, has a change on surving.
There is a possibility for a cockroach to live and die. A cockroach will die from the initial blast, meaning the cockroach will die from the fiery explosion. A cockroach will survive the radiation of the blast, but not the actual blast itself.
As long as you are out of the direct blast, and the building damage ensuing, you may well survive. Many folk from Hiroshima and Nagasaki did so, and just recently, an individual died, who survived BOTH bombs.
Yes this was evidenced in which he was in the center of nuclear bombs that went off to destroy a planet. I think he was knocked out but otherwise survived completely unharmed.
Not if they are close enough. While tough, they will NOT survive heat, blast, and high radiation levels.
Vacuum tube radios.
posibly it depends
