A documentary about St. Louis nuclear workers will screen at 7 p.m. June 22 at Carmike Cinemas 12 in Kennewick.

The film, called The Safe Side of the Fence, “tells of the story of the Mallinckrodt Chemical Works workers who helped refine the uranium for the worlds first self-sustained nuclear chain reaction for the Manhattan Project,” a news release said.

“As a result of their work, the Mallinckrodt workers would become some of the most contaminated nuclear workers in history, and St. Louis would face the challenge of cleaning up some of the worlds first nuclear waste,” it said.
