"Don't confuse the maintenance and lifetime issues of "hydrogen bombs" with those of "atomic bombs". These are worlds apart."

Early atomic bombs have ENORMOUS maintenance requirements.

Beryllium trigger isotopes can have as little as a 53 day half-life, for instance. Polonium 210, a Man-made isotope that can *only* be created in nuclear reactors or cyclotrons, has a 140 day half-life.

I think he was referring to my reference to explosives.

The implication here being that these small devices were made in 1945? These are new things.
