Residents of Shiloh Borough, Stow Creek Township and Greenwich Township, N.J. received potassium iodide tablets in 2011. But the Cumberland County Health Department is asking them to pick up new tablets later this month.
County residents living within 10 miles of the Salem Nuclear Generating Station can receive the KI tablets to take in the event of a nuclear emergency.
But the News of Cumberland County reports some of the tablets distributed last year are only good through 2012.
Tablets will be available to those residents April 18 from 3 p.m. to 7 p.m. at the Emergency Management Building in Greenwich.
