Dayton Project

The Dayton Project in Dayton, Ohio began in 1943 to investigate the chemistry and metallurgy of polonium as part of the Manhattan Project.  By 1946, it was apparent that a larger, more permanent facility was needed and work began on Mound Laboratory in Miamisburg Ohio.  When Mound was completed the Dayton Project work transferred there and work at the Dayton Project locations ended in 1948. 

On February 6, 2012 the Federal Register published the notice that Dayton Project is no longer an AWE site.  The next step is for it to be classified as a DOE site.  We will keep you updated here.

Many thanks to the good people at the Mound Museum in Miamisburg Ohio for the bulk of the Dayton Project documents.

0In 1944 the US government condemned and took possession  of the Talbott family's Runnymede Playhouse in a Court Order by the US District Court, Southern District of Ohio Civil No. 319.  The change of ownership was recorded in Montgomery County's deed book.  The Court Order also dictated the terms of the cleanup that the government was required to perform on the property.
