The following information was received via e-mail from the state of Ohio:
On 9/15/17 at approximately 11:15 AM, the Ohio Department of Health (ODH) was notified by GPD Geotechnical Service, LLC. that a portable gauging device (CPN Model MC-1-DRP which contained a 10 mCi Cesium-137 source and 50 mCi Americium-241:Be source) had been run over and that the device had sustained heavy damage to the casing and the source handle was broken off. The gauging device was run over by a piece of construction equipment at their jobsite located at 225 Elyria Street, Lodi, OH 44254.
An ODH inspector, responded to the location of the incident and was met by the licensee's RSO. The inspector was lead to the gauging device which had been surveyed and had been determined to have no abnormal radiation readings and that both radioactive sources were intact and properly secured with in the device. The device was secured in its transportation case and placed in the field technician's vehicle. The inspector also conducted a wipe test with no abnormal readings observed.
In an interview with the field technician the inspector determined that the technician was approximately 10 to 15 feet away from the device but did not have direct line of site to the device as it was partially obstructed due to the construction equipment. It was also observed by the inspector that the equipment operator's view of the gauging device was obstructed due to the configuration of the equipment and the proximity in which the device was placed on the ground in front of the equipment.
Licensee's leak test showed no removable contamination and the device has been sent to a service provider for repair.
