| Title | Agreement State Report - Well Logging Sources Stuck Down Hole |
| Event Description | The following information was received via fax:
On September 19, 2017, the [Alabama Department of Public Health] received a phone call from Schlumberger, stating that they had failed to notify the Agency [Alabama Department of Public Health] upon entering the State, to perform a job on September 13, 2017, and that two sources (Cf-252 - 18.3 mCi and Cs-137 - 1.78 Ci) are stuck down hole. Schlumberger stated that the first fishing attempt had failed to recover the sources, and the second attempt is now underway. Gathering information is continuing. Alabama Incident: #17-26
On September 24, 2017, after several days of fishing for the logging tools, all recovery attempts had been unsuccessful and the sources were cemented in place down hole. The licensee will follow up with a written report and a picture of the plaque to be placed on the well head. Notified R1DO (Bower) and NMSS Events Notification via email. 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 Note: This device is assigned an IAEA Category 3 value based on the actual radioactivity of the source, not on the device type.
