| Title | Irradiator Safety Equipment Failure |
| Event Description | The NIST (National Institute of Standards and Technology) irradiator has several Cs-137 sources used to calibrate instruments. During a calibration process, a 3.6 Ci source did not return to its shielded position. The event occurred in a portion of the building where such events are expected, therefore there were no health or safety consequences to employees, public or the environment. Licensee corrective actions include manually installing a lead plug into the beam port (opening) of the irradiator. The licensee is contacting the manufacturer in order to assist with troubleshooting and repairs. The irradiator (Model 81-12; JL Shepherd; S/N 7132) is currently in a safe and stable configuration. It is noted that the irradiator is NOT a Part 36 irradiator. |
