"During performance of the Technical Support Center (TSC) Ventilation System Operability Test, an outside air damper failed to close causing a failure of the TSC Ventilation System to attain the required 0.125 inches water column positive pressure. If an emergency condition occurs during the time the repairs are being made, plans are to utilize the TSC as long as radiological conditions allow. Procedure F3-6 ACTIVATION AND OPERATION OF THE TSC, section 7.6, directs TSC management to relocate TSC activities to a radiological safe area if necessary."
The licensee notified the NRC Resident Inspector.

Technical Support Center (TSC) Ventilation System is now operable. R3DO (Steve Orth) notified.
The NRC Resident Inspector was notified of this event update by the licensee. |

| Event Text MEDICAL EVENT - ADMINISTERED DOSE LESS THAN PRESCRIBED DOSE
The treatment consisted of 3 fractionated high dose rate (HDR) brachytherapy procedures. The dose was prescribed by the physician at 5 millimeters from the surface of the cylinder, however, the dose was calculated at the surface of the cylinder. The HDR brachytherapy was administered at 5 millimeters as prescribed. Due to the discrepancy between the prescribed and calculated dose an under dose of the patient of over 4 Grays (Gy) resulted. The prescription was for an administration of 15 Gy. Only 10.3 Gy was administered. The physician is planning to add one more fraction to complete the intended treatment of 15 Gy. The patient will be informed of this misadministration.
The licensee indicated that they will verify the prescription and the film prior to administration to insure consistency between the two. Additionally, when the dose distribution is plotted, the licensee will overlay the cylinder over the dose distribution to visually verify the dose.
A "Medical Event" may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

| Event Text SOURCE STUCK OUTSIDE OF RADIOGRAPHY CAMERA
Team Industrial was performing radiography at the Sinclair Refinery in Tulsa, Oklahoma approximately 25 feet above the ground. During the exposure, the camera fell approximately 3-4 feet onto scaffolding. The fall damaged the ball joint connecting the source to the retraction wire i.e. the source will not retract. The RSO has contacted their corporate office and is contracting with a source retrieval company. The area has been secured and cordoned off. Inability to enter this area does not affect continued refinery operation. The radiography technician received a dose of 40 mR during this incident.

| Event Text AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA STUCK CONTROL ASSEMBLY
The State provided the following information via facsimile:
"During a routine maintenance inspection it was noted that the control assembly [of the radiography camera] would not project or retract the drive cable. After an investigation, it was found that 2 of 4 'small gear housing' screws were interfering with the gear teeth of the large gear.
"The two screws that interfere with the operation of the large gear only interfere when they are loose in the housing. Since the outside of the small housing is where the handle for the controls is kept, the screws inevitably come loose over time and use. Since the screws are applied in the housing there is no way to tighten the small housing screws with out disassembling the control arm assembly.
"A small design change is needed on these 4 small housing screws to prevent a source from stuck out in the shielded position."
Equipment involved: SPEC 150, (no serial number provided), Source: Ir-192 (no source strength provided), Control assembly: SPEC 'Red-Red' conduit control. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text LOST I-125 SEED
The licensee was performing a prostate seed case requiring 12 loose I-125 seeds with an activity of .34 mCi each. The seeds were assayed in the licensee hot lab and transported to the operating room for the procedure. After completion of the procedure only 11 seeds were accounted for. The RSO was notified. The seed was verified to not be in the patient. The licensee completed search for the material throughout the operating room and hot lab with no success. The licensee contacted the NRC Region 1 representative.
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. |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text MISSING/LOST NICKEL-63 15 MILLICURIE SOURCE
The Radiation Safety Officer (RSO) for The United States Environmental Protection Agency located in Cincinnati, OH reported they are missing a 15 millicurie Ni-63 source. The source was last seen December 01, 2006 when its 6 month leak test was performed. After the source was leak tested, the source was placed back in an unlocked drawer, where it has been kept since December 2001. The source was located below the HP Model # 5890 Series II Gas Chromatograph in which is it was used. The RSO said that they have been looking for the missing source since early June and they have been unable to find the source. The RSO said that anybody working for the US EPA in their building can enter the room in which the source was stored.
