On August 12, 2010, the DOT paperwork was faxed from Utah to the Department. The DOT special permit indicated the material was a railcar with a side which scanned at 22 [micro]R/hr (background = 0.005 mrem/hr). | On August 12, 2010, the DOT paperwork was faxed from Utah to the Department.

On August 19, 2010, the railcar was returned to Van Gundy Ampco in Grand Junction. The Department made the determination using an IdentiFinder that the material was an oilfield pump contaminated with Ir-192 with a dose rate of 0.34 mrem/hr. The pump was isolated from public and workers with barrier tape. | On August 19, 2010, the railcar was returned to Van Gundy Ampco in Grand Junction.

The pump was isolated from public and workers with barrier tape. | ||
On August 25, 2010, Protechnics (license CO-545-01) agreed to take possession of the pump to decay in storage. Protechnics is licensed for Ir-192, so no provisional license will need to be issued to Van Gundy Ampco or Protechnics. On August 27, 2010, Protechnics took possession of the oilfield pump. Personnel from Protechnics cleaned an oily residue out from the oilfield pump. The pump at this point scanned as indistinguishable from background and was released for unrestricted disposal. The oily rags and materials used to decontaminate the pump were taken to the Protechnics site in Fruita, Colorado for decay in storage. | On August 25, 2010, Protechnics (license CO-545-01) agreed to take possession of the pump to decay in storage.

The source of the Ir-192 is unknown as the oilfield pump was in a railcar full of scrap metal and the pump bore no identifying marks. Therefore, no Notice of Violation has been issued in regards to this incident. Additionally, the public dose in regards to this incident is also unknown as it is not known how long the pump was in public and the route the pump took from the oilfield to the scrap yard. | The source of the Ir-192 is unknown as the oilfield pump was in a railcar full of scrap metal and the pump bore no identifying marks.
