| ENS 57076 | 15 April 2024 12:28:00 | The following information was received from the Colorado Department of Public Health and Environment via email: This letter is serving as notification of an equipment failure under (Colorado Regulation) Section 4.52.2.3 and 5.38.1.3. A QSA Global 880 Delta camera was received from Source Production and Equipment Company, Inc. (SPEC), after being resourced. During the check-in procedure and mechanism check, it was discovered that the lock that controls access to the pigtail attachment was broken in the locked position. The camera was tagged out until it could be sent to Industrial Nuclear Company (INC), for repairs on 04/04/2024. The lock was repaired at INC, and the camera was returned to the licensee on 04/10/2024 with no issues. Colorado Event Report ID: CO240011 |
| ENS 56901 | 20 December 2023 08:04:00 | The following is a summary of information provided by the Colorado Department of Public Health and Environment via email: The licensee, Medical Center of Aurora, discovered a leaking sealed source on December 18, 2023, during a routine semi-annual inventory and leak test. The sealed source is an Eckert and Ziegler (Serial Number 1360-6-20) Cs-137 vial with estimated current activity of 0.136 millicuries. The plastic vial had been stored in a lead box since the last inspection, but it was discovered that the plastic was cracked. Wipe test showed 0.052 microcuries of removable activity inside the storage box. No contamination was found outside of the box. The source vial will be wrapped in several layers of plastic to stabilize it and limit contamination inside the box. The licensee has contacted the manufacturer to return the source.

| ENS 55302 | 10 June 2021 19:36:00 | The following information was received via E-mail: Event description: portable gauge came out of truck bed during transport. Event location: South Broadway and 340, Grand Junction, CO. Event type: Lost portable gauge, Troxler 3430 SN 26906, 333 MBq (9 mCi) of cesium-137 and 1.63 GBq (44 mCi) of americium-241:beryllium; or 2.44 MBq (66 microCi) of californium-252. Colorado Event Report ID No.: Pending
The following update was received via E-mail: The portable gauge reported lost by Colorado on 6/10/21 has been found. The gauge was found by an employee at the worksite where the gauge fell off the back of the truck and was secured. The licensee was notified and has recovered the gauge. Notified R4DO (Drake) and NMSS Events Notification and ILTAB 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.

| ENS 51470 | 15 October 2015 13:55:00 | The following information was provided by the State of Colorado via email: The (licensee) RSO reported that a patient received 40 percent less than the prescribed dose during a TheraSphere (Y-90) treatment on 10/14/2015. The exact cause is still under investigation. Initial written direction was for 120 Gy. However, due to unavailability of this dose the written directive was amended to 140 Gy and the dose was ordered. The AU (Authorized User) reported that stasis was not reached and it was believed the patient received the entire dose. The associated survey meter was reading 0 and the AU flushed the system 3 times - the meter continued to read 0. The procedure ended around 1430 MDT. After the procedure the AMP (Authorized Medical Physicist) reviewed the paperwork, took waste measurements and performed calculations. At this point 40 Gy was found in the waste. The RSO was notified at 1545 MDT. At this time, it is not known if the patient has been notified. 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. |
| ENS 50401 | 26 August 2014 16:25:00 | The following was received from the State of Colorado via email: At 0948 MDT on the morning of August 26, 2014, (the State of Colorado) was notified by the ARSO at Terracon, Inc (Colorado License # 664-02) that a Troxler 3430 moisture/density gauge had been run over by a skid-steer at a temporary job site. The source was locked in the shielded position when the gauge was hit. Surveys taken at the site confirmed that the source remained shielded. The gauge was placed in its transport case (Transport index confirmed) and taken to Instrotek for leak testing and analysis. Final results should be available within a week and initial results show no evidence of leakage. The investigation is still ongoing. |
