The following information was reported by facsimile.
The North Carolina Department of Environment and Natural Resources reported a damaged Troxler moisture density gage during construction activities in Reidsville, NC. The NC Radiation Protection Section dispatched a health physicist to the site, the health physicist secured the damaged gage on site and conducted radiation exposure surveys to access the status of the radioactive sources. All indications and surveys support that no radiological damage occurred to those workers involved and no damage was incurred to the environment.
Damage to the gage resulted in a potential loss of shielding. If the gage is mishandled the source rod will pull out. The gage was secured and the sliding block was closed.
Stakeholders and responsible parties were contacted and are arranging to have the gage appropriately transferred to the manufacturer for further evaluation.
