AGREEMENT STATE REPORT - TROXLER MOISTURE DENSITY GAUGE LOST THEN FOUND
The following was received from the State of Texas via email:
"On September 23, 2014, the Agency [State of Texas] was notified by the licensee of the loss of a Troxler Model 3411 moisture density gauge, serial #6329, containing a 1.48 GBq (40 mCi) Am-Be source, serial #47-2502, and a 0.3 GBq (8 mCi) Cs-137 source (serial #40-3459). The licensee stated a technician was traveling when his tailgate fell open and the container holding the locked gauge fell off the truck. The gauge was improperly secured in the back of the truck. He turned around to go back to the intersection but the gauge was missing.
"On September 24, 2014, a company called the licensee informing them that they found the gauge in the road. The gauge was returned to the licensee. Additional information will be provided as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - STUCK SOURCE
The following report was received from the State of Colorado via email:
"Event description: The department [Colorado Department of Public Health and Environment] was notified via phone on 9/23/2014, at approximately 1845 [MDT] by the Radiation Safety Officer [RSO] of Premier NDT Services, Inc. (license # CO 1162-01) that a radiography crew was unable to retract the source assembly to its fully shielded position and secure it in this position at a temporary job site.
"At approximately, 1900 [MDT] on 9/23, the RSO reported to the department [Colorado Department of Public Health and Environment] that the source had been retracted to it fully shielded position by working the crank back and forth a few times. It was about a quarter turn to get the source into position and have the exposure device lock engage. The source was not fully extended outside of the camera but was in the camera enough to close the outlet port cover.
"The radiography camera was surveyed and it was determined that the source was in fact in its fully shielded position prior to transporting the camera back to the licensee facility.
"The department [Colorado Department of Public Health and Environment] visited the licensee facility on 9/24/14, at approximately 0930 [MDT] and interviewed licensee staff including the radiography crew.
"It was determined that the radiography assistant had not properly surveyed during the approach to the camera to verify that the source was in fact in its fully shielded position and that he disconnected the guide tube prior to realizing that the source was not fully shielded. When he attempted to disconnect the drive cable he realized that the exposure device lock was not engaged properly and the crew retreated to a safe distance.
"There were two assistant radiographers and a radiographer present and their pocket dosimeters read 10, 9 , and 20 mrem after the event. It appears unlikely that this is an overexposure event. The time in which the crew was in close proximity to the camera with the source out of its secured position was less than 5 minutes total and the time in which the crew member was in contact with the camera was less than a second to disconnect the guide tube and close the outlet port cover and another second when he attempted to disconnect the drive cable.
"It is suspected that this was a malfunction of the device. The camera (QSA 880 Delta), drive cables, and guide tube are being sent back to the manufacturer for diagnosis.
"The department [Colorado Department of Public Health and Environment] is preparing a Notice Of Violation for multiple items and is expecting a full report from the licensee within 30 days including dose estimates."

AGREEMENT STATE REPORT - STUCK SOURCE
The following report was received from the State of Texas via email:
"On September 24, 2014, the Agency [Texas Department of State Health Services] received notice that on September 22, 2014, there had been a radiography source retraction failure at a temporary field site. A pipe had fallen from a stand onto the guide tube, causing a crimp. The source was retrieved by squeezing the crimp with pliers, allowing retraction. The individual performing the retrieval received 387 mrem according to a pocket dosimeter. The camera was a SPEC 150 (sn 1599) with an Ir-192 source at 49 Ci (sn VG010). Additional information will be supplied as it is received in accordance with SA-300."

AGREEMENT STATE REPORT - FAILURE OF A PROCESS GAUGE SHUTTER
The following was received from the State of Nebraska via email:
"The Nebraska Department of Health and Human Services, Radioactive Materials Program, was notified at 0803 CDT on 9/25/2014 by a representative of the Omaha Public Power District that a Kay Ray fixed gauge Model Number 7080 source shutter failed to close. The device contains approximately 6 millicuries of Cesium-137 originally installed in 1984 with approximately 50 millicuries. The gauge is mounted between two fly ash hoppers approximately 20 feet above the floor. The source closure mechanism on the gauge is connected to a handle located at floor level by a flexible cable. The closure cable is secured so that when the floor handle is operated, the control cable slides inside of the sheath opening/closing the shutter. The outer sheath for the cable became separated from the capture mechanism at the source. The handle on the floor would move but the linkages at the source would only move approximately « inch and then the sheath would move away from the compression fitting. The reason for operating the source shutter was to perform the semiannual function check.
"This type of failure has been seen in the past and is easily fixed by tightening the screw which secures the end of the cable to the structure. This requires a scaffold to be built up to the source level."

Event Text
LOST DEPLETED URANIUM SHIELDS
Mallinckrodt reported the loss of six (6) depleted Uranium shields used as shielding for Tc-99m generators. The licensee believes that the shields were lost in transit between 5/2013 and 9/2013. Five of the shields were in transit between Mallinckrodt and Triad Isotopes (locations in Texas and Hicksville, NY) shipped by "Associated Couriers." One of the shields was in transit between Mallinckrodt and Cardinal Health (Plainville, NY) shipped by "Medical Delivery Services." Each shield is roughly 12 inches in height, 8 inches in diameter, 65 pounds in weight, and contains 8.1 mCi of Uranium. The dose rate on contact would be roughly 3.1 mrem/hr, and the dose at 1 foot would be roughly 1.2 mrem/hr.
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.
