The Pennsylvania Department of Environmental Protection wants to know who tossed an 'antique medical kit' containing Radium-226 in some construction trash.
The kit was discovered in a Chester County trash bin on Jan. 19, along with a load of construction debris.
The box set-off a radiation alarm at Waste Management's Norristown transfer station, according to a DEP release asking for the public's help.
"The radioactive material may have been contained in the kit for more than 80 years," The DEP's Bureau of Radiation Director David Allard said. "The metal box likely came from a basement, an attic or a collector's stash. Anyone who tampered with it or stored it for a long time may have been exposed to high levels of radiation."
