LEWISTON, Idaho (AP) — The Environmental Protection Agency says a depleted uranium cylinder found at a northern Idaho metal workshop posed no danger to the public but it's unclear how the cylinder came into the company's possession.

Greg Weigel of the EPA tells the Lewiston Tribune in a story on Saturday that a property owner cleaning a building in April found the cylinder in a box of salvaged metal at the Thomason Chemical Co. in Craigmont. Weigel says the cylinder wasn't highly radioactive, but needed to be properly dealt with.

Weigel says the company has no record of how it received the cylinder. He says the EPA considers the cylinder an orphaned source because there's no record of its background and officials don't know where it came from.
