"While conducting radiography shots at a water tank construction site, ATS radiography crew experienced a source hang up. Radiographers initially believed the cause to be a crimped guide tube due to source not moving in either direction. While maintaining a 2 mR/hr boundary, additional personnel were dispatched to the work site by ATS with additional shielding material and [the] RSO [radiation safety officer] who is responsible for source retrievals. Lead blankets were placed on the guide tube and the RSO determined that the guide tube was not compromised, kinked, crimped or otherwise damaged. Probable cause was determined to be in the control assembly. RSO unthreaded the guide from the outlet adapter and exercised the controls with no effect. Guide tube was reconnected and RSO began to troubleshoot the connection side of the camera by removing the housing from the connection to observe the cable while again exercising the controls. Cable would flex but was observed to be either wedged or pinned at the connector. During this process, it was observed that since the cable would not flex on the outlet side of the camera it was determined that extreme force on the controls side would not result in the cable being disconnected from the pig tail. The housing was reattached, and extreme force was used on the controls to break the cable free and the source was returned to its secured and shielded position. The RSO observed the control assembly crank did have more movement than usual, and root cause was determined to be debris from a damaged bearing that had moved down the control cable housing and locked up the controls. This equipment had quarterly maintenance and weekly inspections conducted on it. [The] controls were shipped to QSA for repair or disposal. All personnel involved in the source retrieval received doses well within annual limits for radiation workers.
"RMB has concluded its investigation and consider this event Closed & Complete. No other agencies were informed of this event and no other generic issues identified."

The following information was received via email.
"Tower Plastics Mfg., Inc. reported that their two remaining generally licensed NDC Model 103 gauges (SN's 2160 and 2161 containing 150 mCi/Am-241 each) were destroyed in a fire on December 3, 2015. This was reported during the IEMA [Illinois Emergency Management Agency] 2018 annual source reconciliation. The licensee reported that the site was completely destroyed in the fire and debris was hauled to a landfill. Records of the disposal and an IEMA survey of the site are pending."
Item Number: IL180030
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.

PATRICIA MILLIGAN (INES) | Event Text POTENTIAL OVER EXPOSURE FROM RADIOGRAPHY OPERATION
The following information was summarized from an email received from the state of Kansas:
[The licensee RSO] (DBI) reported to the KDEM [Kansas Division of Emergency Management] 24-hour number that they had a potential over exposure during a radiography operation.
The radiographer was in the process of setting up the last shot of the day. While returning to the crank, the radiographer was radioed by the refinery's QC person. At the same time, he was adjusting the collimator, which had shifted. The QC person called over the radio 'come on' which the radiographer's assistant (on the same radio channel) took to mean to crank out the source. When the radiographer felt the vibration of the source being cranked out, he dropped the collimator, exited the area immediately, and got the source retracted.
Preliminary worst case calculations indicated a possible extremity over exposure. The radiographer's badge was sent in for processing and the report came back with 33 mR for the period since April 9. With this information, the extremity dose will be recalculated to determine the actual exposure to the individual.
PQT Services Inc. and REAC/TS consulted on the incident. The worst case scenario is that the radiographer could have received a dose from 50 - 100R to the hands. Pictures of the radiographers were inspected for signs of radiation burns. No signs at this time. The plan is to continue to monitor his hands until June 20, 2015. Both PQT Services and REAC/TS agree that this should be a sufficient time to assure the safety of radiographer. The radiographer's annual dose was DDE 262 mR.
Root cause of incident was determined to be weakness in the communication procedures established between personnel during radiographic operations. A visual 'ALL CLEAR' confirmation from the radiographer setting up the exposures must be made with the person operating the exposure device before the source is exposed.
All DBI Inc. employees have been notified of this incident and the importance of a visual confirmation prior to exposing the source. This has been implemented in DBI's protocol.
This event is considered closed.

The following information was received from the state of Wisconsin via email:
"On July 17, 2018, the licensee identified a medical event where the total dose delivered differed from the prescribed dose by 20 percent or more. The licensee implanted 83 seeds containing Pd-103 for prostate brachytherapy. The prescribed dose to the prostate was 125 Gy; the dose delivered was 96.25 Gy. The dose received by the prostate (D90) was 77 percent of the intended dose. The patient has been notified. The implant occurred on June 8, 2018, and post-implant dosimetry was completed on July 17, 2018. The department will perform a site investigation to determine the root cause of this medical event."

The following information was obtained from the state of California via email:
"On July 16, 2018, the California Office of Emergency Services (OES) contacted RHB [California Radiation Health Branch] to report the recovery of a stolen moisture density gauge. The gauge recovery was reported to OES by the San Jose Police Department. The service truck containing the moisture density gauge was stolen from a private residence sometime over the weekend, and was found by the San Jose Police Department during patrol early on July 16, with the gauge still chained to the bed of the truck. The San Jose Police Department cut the chain and stored the gauge at the station. The moisture density gauge is a CPN Model MC-1DR-P, S/N MD60508312, containing 10 mCi of Cs-137 and 50 mCi of Am-241. The gauge was collected by RHB and put in RHB storage on July 16. RHB will be following up with the licensee concerning adherence to regulatory and license requirements."
