“The work in Dayton was so essential to the success of the bomb project and so deeply hidden within the already-secure Manhattan Project…” (60).
The Book
When most people hear about the development of the atomic bomb, their first thought is not Dayton, Ohio. Author Linda Carrick Thomas sets out to change that in Polonium in the Playhouse: The Manhattan Project’s Secret Chemistry Work in Dayton, Ohio. That secret work, to produce refined polonium for the nuclear bomb trigger mechanism, still remains the most classified aspect of the Manhattan Project today.
The first atomic bomb was dropped on August 6, 1945. Only
seven years earlier evidence of nuclear fission was found in uranium, making
atomic weapons possible; and, four years earlier British scientists announced
that an atomic bomb could be ready in two years. These two events accelerated
the work of US scientists and military personnel in atomic weapons. The
Manhattan Project was created in the summer of 1942 and housed in the Army, to
ensure total secrecy. There were several locations throughout the country that
were compartmentalized to help protect the work from any leaks.
Dayton was home to several locations, beginning in the spring
of 1943. The Dayton Project operated in the Monsanto laboratory, leased space
from the Dayton Board of Education, and converted the Talbott family’s private
hall. The latter two were located in the heart of neighborhoods.
Twenty-four-hour guards kept an eye on the work, as trucks with radioactive
material drove in and out of the facilities. The chemists in Dayton purified
polonium for the plutonium implosion bomb, with the first shipment for purification
arriving in April 1945. Three months later, there was enough purified to test
the first atomic bomb in New Mexico. Just two weeks after that, the parts for
the plutonium bomb (Fat Man) arrived in the Pacific and it was dropped on
Nagasaki August 9. It isn’t until then that the Dayton Project workers finally
learned what they had been working on.
After World War II, nuclear research transitioned to
universities and national laboratories. A new facility was built in Miamisburg,
Ohio to continue the polonium work until it was decommissioned in 1993. Parts
of the Dayton Project were declassified in 1983 and the late 1990s. As of the
writing of this book, 2017, some is still classified.
Polonium in the Playhouse is a compact book that introduces the reader to many different parts of the story: the Manhattan Project, the Dayton Project, chemistry and nuclear research, and key individuals. For the most part, the chapters move quickly and the science is easy to follow. Thomas situates the Dayton Project within the greater Manhattan Project, explains the methods for recovering polonium from lead dioxide, and describes the polonium purification process. I found it helpful to read the first appendix, a science primer, before the narrative dives into the development of the bomb (in between chapters two and three). Black and white photos, charts, and drawings—directly related to the surrounding text—help readers visualize the people and science.
The Place
The Mound Cold War Discovery Center could be easily missed. It’s 20 minutes south of Dayton and in an unassuming office building. Across the street is the Miamisburg Mound, a prehistoric burial site that commands your attention more than the Discovery Center. However, once inside, visitors quickly learn how significant this site was to the ending of World War II. When I went with my dad—a former chemist and employee for a nuclear energy company—we spent quite a bit of time there. The accessible hands-on exhibits and artifacts helped to tell the story that began with racing to develop an atomic bomb and ended with satellite communications. I particularly enjoyed the Geiger counter that demonstrates how radiation protection works. The Discovery Center is open Wednesday-Saturday from 10am to 4pm; admission and parking are free. It is self-guided, but group tours can be arranged. Depending on your interest level, you could spend less than an hour or over an hour there. The Mound Cold War Discovery Center is worth the drive, for it is just another reminder about the role Dayton has played in historic events throughout the years.
