Ray Bradbury. Ray Harryhausen. Radioactive dinosaur loose in Manhattan. What’s not to like? I was inspired to watch The Beast from 20,000 Fathoms again for a single line, where Dr. Nesbitt informs the marksman his grenade has “the only isotope of its kind this side of Oak Ridge.” You see, I had just finished reading Denise Kiernan’s The Girls of Atomic City: The Untold Story of the Women Who Helped Win World War II. Atomic City, in this context, is Oak Ridge, Tennessee, a city built almost overnight with one objective: to produce uranium for the atomic bomb, then under development. The employees, many of them women, were not told the nature of their work and were not allowed to speak about the little they knew, putting many strains on marriages and human relationships. It is a captivating story, especially since Kiernan doesn’t pull any punches—the facility was in a segregated south, women scientists were belittled to their faces, and the end result was thousands of people incinerated in Japan. It is like the end of Eden, the loss of humanity’s innocence.

Growing up in the 1960s, I had heard of Oak Ridge. I knew it had something to do with nuclear stuff, but my understanding only went as far as the planetary model of the nucleus of an atom. I feared nuclear war. The height of that fear in the 1950s may have passed, but I was born just a month before the Cuban Missile Crisis began and all through the Reagan era that veiled threat of total, mutual annihilation hung heavily in the air. The religious had claimed God had created all this, but human hubris threatened to erase it all. On the eve of a friend’s wedding I sat across the Susquehanna River, eyeing Three Mile Island for the first time. Just six years earlier even those of us hundreds of miles to the northwest wondered if we would succumb to its radioactive glow. The power of the atom, as Kiernan demonstrates, was considered to be the basic power of the universe. And it was not divine.

When the war was over, a symbol of peace was erected at Oak Ridge. The International Friendship Bell was challenged as recently as 1998 by a local claiming that ringing the bell endorsed Buddhism, and it was therefore a religious symbol that had no business in a public place. For those who believe, ringing the bell is a form of Buddhist prayer. For others, it is a sign of goodwill between nations that have put their differences to rest. It is easy, sixty years after the release of The Beast from 20,000 Fathoms, to laugh smugly at Harryhausen’s famed stop-motion animation and the incessant worry about atomic fallout. But near the beginning of the movie, George Ritchie says of the atomic blast they’ve been monitoring, “You know, every time one of those things goes off, I feel as if I was helping to write the first chapter of a new Genesis.” Indeed, at least as far as chapter three. With the dawn of the atomic age, we had outgrown our need for the final chapters of Revelation as well.
