an a-bomb involved fission only.
an h-bomb involves fission first, and a femtosecond later, a fusion reaction and chain-reaction, making for a bomb 1,000 times stronger than an a-bomb. Technically it’s two explosions.
We dropped two a-bombs on Japan, no h-bombs.
Oops
Slip Mahoney said the H-bomb was invented by a guy named, Hydrogen.
