There are no unnatural levels of radioactivity at a former Navy research facility at Camp Lejeune, or near a base rifle range where material from the laboratory was buried decades ago.
That's according to an analysis sought by base officials after a document was discovered earlier this year that said the Navy had "safely stored" 160 pounds of soil and two animal carcasses laced with strontium-90.
The isotope causes cancer and leukemia.
According to paperwork from 1981, the material was awaiting shipment to a disposal site in South Carolina, but military officials couldn't find definitive proof that it had been moved.
New World Environmental Incorporated conducted the analysis. The company determined that the incinerator used to burn the carcasses
sufficiently diluted the radiation.
