Up to 2,000 or more affected by radioactive material from Portsmouth plant, suit says

As many as 2,000 people, or more, may have been adversely affected by the release of radioactive materials from the Portsmouth Gaseous Diffusion Plant, according to a class-action complaint filed Sunday in federal court in Ohio.

Ursula and Jason McGlone, Julia Dunham and her children are named as plaintiffs in the suit. Several companies are named as defendants, including the Unites States Enrichment Corporation, now known as Centrus Energy Corp., which operated the plant from 1993 to 2001. The company also was responsible for plant safety for a decade ending in 2011, according to the suit.
