| Title | Agreement State Report - Unplanned Contamination |
| Event Description | The following was received via e-mail:
On January 8, 2019, the Agency [Texas Department of State Health Services] was contacted by the license and notified they have some conflicting data that suggest they may have up to three (3) leaking Nickel (Ni) - 63 ten milliCurie sources that may be slightly above the 0.005 microCuries reporting limit. The licensee stated they need to investigate further as a second set of leak tests showed no detectable activity on the same three sources. The three sealed sources in question have been bagged and are slotted for disposal. The licensee will provide additional information as it is received. On January 25, 2019, the licensee contacted the Agency and stated they had leak tested all similar sources in their possession. The licensee found a total of four sources exceeded the limit. The sources are all Ni-63 containing 10 milliCuries. The licensee stated they will dispose of all leaking sources. The licensee stated it believed the sources were manufactured in Singapore. The sources are used in gas chromatographs. The Agency conducted an on site investigation at the facility on March 11, 2019. During the investigation the licensee stated none of their customers who had been provided a device had reported a source that failed a leak test. On April 3, 2019, the Agency was notified by the licensee that they were going to restrict access to a room for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> due to fixed and removable radioactive contamination levels.
