Thee Geography of Fallout: Major Teszt Sites andTheir Histories

Nuclear testing was a random scatter of explosions. It followed deliberate geographic and stratec logic, often projecting demote islands, desert basins, and Arctic archipelagos. These locations were chosen for their perceived isolation, but isolation proved illusory when n radioactive debris drifted across contints and oceans.

Lokat About 65 mils northwess of Las Vegas, thee Nevada Tess Site (NTS) hosted 928 nuclear tests between 1951 and1992.
