Dose rate readings using a ND-2000A survey instrument, calibrated 09/16/22 indicated readings as high as 30 mR/hr on the surface of the transport container and less than 1 mR/hr at 1 meter.
The Troxler 3400 series moisture density gauge was transported and secured at the licensee's storage location and is awaiting shipment back to the manufacturer. This event is still under investigation by the South Carolina Department of Health and Environmental Control.
