The Atomic Age Playground
On January 27, 1951, a nuclear bomb was detonated at the Nevada Test Site, 65 miles northwest of Las Vegas. The mushroom cloud was visible from the Strip. Rather than panicking, Las Vegas embraced the spectacle with the same enthusiasm it brought to everything else — turning existential dread into a marketing opportunity.
Hotels advertised "atomic cocktails" and held "dawn bomb parties" where guests gathered on rooftops and poolside to watch the predawn flashes light up the desert sky. The Las Vegas Chamber of Commerce published calendars of upcoming detonations so tourists could time their visits. Beauty queens were crowned "Miss Atomic Bomb," posing in mushroom cloud-shaped costumes. Between 1951 and 1992, there were 928 nuclear tests at the Nevada Test Site, 100 of them above ground — and Las Vegas profited from every flash.
The Legacy
The atmospheric tests ended in 1963 after the Partial Nuclear Test Ban Treaty, though underground testing continued until 1992. The spectacle was over, but the consequences were just beginning. Thousands of soldiers, workers, and downwind residents had been exposed to radioactive fallout. "Downwinders" in Nevada, Utah, and Arizona suffered elevated rates of cancer for decades, leading to lawsuits and eventually the Radiation Exposure Compensation Act of 1990.
The Nevada Test Site is now the Nevada National Security Site, still used for subcritical nuclear experiments and national security research. The National Atomic Testing Museum in Las Vegas, a Smithsonian affiliate located at 755 E. Flamingo Road, preserves the history of nuclear testing with exhibits including a simulated blast experience, authentic artifacts from the atomic age, and sobering documentation of the human cost. It stands as a reminder of the era when Las Vegas marketed the apocalypse as entertainment.
Key Facts
928 Nuclear Tests
Between 1951 and 1992, 928 nuclear devices were detonated at the Nevada Test Site, 65 miles from the Strip. One hundred of those tests were above ground.
Miss Atomic Bomb
Las Vegas casinos crowned beauty queens "Miss Atomic Bomb" during the testing era. The iconic photos of showgirls with mushroom cloud imagery became symbols of atomic-age America.
Dawn Bomb Parties
Hotels hosted rooftop and poolside viewing parties for predawn nuclear detonations. The Chamber of Commerce published detonation calendars so tourists could plan their trips.
Downwinders
Thousands of residents in Nevada, Utah, and Arizona were exposed to radioactive fallout from atmospheric tests, suffering elevated rates of cancer for decades afterward.
