How do governments and militaries test out nuclear weapons without creating disastrous effects on the environment/ecosystem?

Question

Just like the title says, I don’t understand how they can test nuclear bombs in the desert, or Bikini Atoll (in the ocean) without permanently irradiating the ecosystem (and consequently, Earth) beyond repair.

They’ve tested dozens and dozens of nuclear bombs throughout the years, and I’m confused why that hasn’t messed our world up?

Answer 1

The earth is large, like very impossible to put in scale large, and in spite of their immense power, nuclear weapons still rather small. There’s enough remote places to test nuclear weapons in forever and there are several other very natural phenomena which release much more energy and carnage than a nuclear weapon.

Tbh, they often test nukes in rather remote wastelands so the only organisms complaining are probably like the three bacteria who live there.
