The following information was obtained by the state of
Texas via email:
On April 13, 2018, at approximately 8:55 p.m. [CDT], U.S. Customs and Border Protection (CBP) notified the Agency [Texas Department of State Health Services] that it had discovered and identified a cesium [fixed] gauge - Thermo Fisher Scientific Model 5192, containing 200 milliCuries of cesium-137, SN: B8087 - in the bed of a pickup truck of an individual (road construction worker) who was crossing from Texas into Mexico at the Tornillo-Marcelino Serna port of entry in Tornillo, Texas. The individual told the CBP officer that he had found the gauge on the side of the road near Kermit, Texas, and had picked it up and put it in the back of his truck as he was leaving that area to travel to Mexico ('home'); he collects scrap metal and sells it across the border. CBP took possession of the device and the Agency contacted the owner/licensee. The licensee dispatched an employee who retrieved the device at approximately 6:00 a.m. on April 14, 2018. The licensee reported that the device packaging appeared to be secure and has performed a leak test which was sent to a third party for analysis. While there has been no indication that any individual has been exposed above any regulatory limit, the licensee's and Agency's investigations thus far have not been able to definitively make that determination. Therefore, this report is being submitted. More information will be provided as it is obtained in accordance with SA-300.
