As you wrap your head around particles from wildfires creating risk 1000s of km away, and even on the other side of the world, use this to understand how radioactive fallout particles from nuclear weapon "tests" spread radioactive particles all around the world.

They have been found on every continent, at the poles, in the Mariana Trench, even in #Hiroshima & #Nagasaki.

This is the fallout cloud from the #Bravo test in the Marshall Islands in 1954, taken 15 minutes after detonation. H-bomb tests brought these particulates high into the upper atmosphere where they circled the Earth before "falling out" all across the globe. Many remain dangerous for 100s or 1000s of years.
