| Title | Potential Lost Sealed Source Containing 1.8 Curies Tritium |
| Event Description | The following information was received from the State of Texas via email:
On June 29, 2009 Hotwell US LTD received a new shipment of two tritium well logging tools from their manufacturer in Austria. The tools each contain a 1.8 Curies (Ci) tritium sealed source inside a 15,000 psi pressure housing. These tools were slated for sale and delivery to Competition Wireline (NRC License No. 25-27802-1) out of Billings, Montana. After arriving at the facility in Houston, Texas, the tools were checked and shipped via [common carrier] to Competition Wireline. One tool (No. 33264) arrived at Competition Wireline on July 1, 2009. On July 6, 2009, Competition Wireline verified to Hotwell US LTD that the other tool (No. 33284) had been received. On October 13, 2009 Competition Wireline reported to Hotwell US LTD that after a general inventory of equipment, they could not locate one of the tools (No. 33284). The licensee has alleged that [the common carrier] never delivered the tool and found that it was last tracked to Memphis, Tennessee. [The common carrier] now shows the package as 'In Transit'. Competition Wireline has notified [the common carrier], and [the common carrier] is conducting an investigation into the location of the package. The missing tool is described as follows: Tool No. 33284 Monoblock No.: 99448 Model No.: ING-10-50-120-TBT Description: 84 x12 x8 Black Crate Texas Incident Number I-8677. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source. |
