PIKETON, Ohio - Participants in the first monthly seasonal public site tour of 2018 at EM's former Portsmouth Gaseous Diffusion Plant wave farewell Saturday at the end of their visit. Among them were three former workers from the earliest days of the uranium enrichment plant in the 1950s. The oldest among them, Gene Marsh (center), turns 90 next month.
