ND Testing Inc. made a 24-hour report to the Radiologic Health Branch that on October 8, 2020, at 1256 PDT a hand-crank assembly became stuck/seized and would not allow the source to travel forward or backwards at a temporary job site. The team of two experienced radiographers contacted their Radiation Safety Officer (RSO) for assistance and secured the area around their QSA Global 880 exposure device.
The RSO arrived onsite at 1445 EDT with extra lead shielding and survey meters. He and the radiographers were able to place lead blankets and some solid lead blocks over the guidetube containing the Ir-192 source, open the crank assembly to remove some metal shavings and close the assembly. This allowed them to secure the Ir-192 source after approximately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 1645 EDT.
