| Title | Agreement State Report - Inoperability of the Access Control System |
| Event Description | The following was received from the State of Colorado via email:
CDPHE [Colorado Department of Public Health] received telephone notification of an inoperability of the access control system on 8/14/2014 at approximately 1445 [MDT]. Colorado State University, a research licensee, reported that a radiation monitor provided to detect the presence of high radiation levels in the radiation room of a panoramic irradiator was alarming when there was no [abnormal] radiation level present. One of the irradiator users noticed the audible alarm when their work was complete and they were leaving the area. The RSO responded and suspected a stuck source. Using a hand held radiation detection instrument, the irradiator door was opened and the irradiator room was entered. As the RSO entered the room there was no indication of radiation levels above what was expected when the source is in its shielded position, and as a result, it was determined that the source was in its shielded position. The room radiation monitor was reset but shortly after again alarmed without any [abnormal] radiation field present. The irradiator has been taken out of service and the monitor has been removed for repair. Colorado event report ID: CO14-I14-22 |
