ENS 4621330 August 2010 13:03:00On August 3, 2010, the Department (Colorado Department of Public Health and Environment) received a phone call from the Utah Division of Radiation Control. A steel mill in Utah was returning a shipment of scrap metal to Colorado due to the portal monitor indicating radioactive material present in the shipment The shipment origin was Van Gundy Ampco at 1018 S. 5th Street, Grand Junction, Colorado (a scrap metal company, not a radioactive materials licensee). On August 12, 2010, the DOT paperwork was faxed from Utah to the Department. The DOT special permit indicated the material was a railcar with a side which scanned at 22 (micro)R/hr (background = 0.005 mrem/hr). On August 19, 2010, the railcar was returned to Van Gundy Ampco in Grand Junction. The Department made the determination using an IdentiFinder that the material was an oilfield pump contaminated with Ir-192 with a dose rate of 0.34 mrem/hr. The pump was isolated from public and workers with barrier tape. On August 25, 2010, Protechnics (license CO-545-01) agreed to take possession of the pump to decay in storage. Protechnics is licensed for Ir-192, so no provisional license will need to be issued to Van Gundy Ampco or Protechnics. On August 27, 2010, Protechnics took possession of the oilfield pump. Personnel from Protechnics cleaned an oily residue out from the oilfield pump. The pump at this point scanned as indistinguishable from background and was released for unrestricted disposal. The oily rags and materials used to decontaminate the pump were taken to the Protechnics site in Fruita, Colorado for decay in storage. The source of the Ir-192 is unknown as the oilfield pump was in a railcar full of scrap metal and the pump bore no identifying marks. Therefore, no Notice of Violation has been issued in regards to this incident. Additionally, the public dose in regards to this incident is also unknown as it is not known how long the pump was in public and the route the pump took from the oilfield to the scrap yard. This incident is considered closed. Colorado Incident I10-11
ENS 4634319 October 2010 13:07:00The following report was received via fax: This memo is to serve as a preliminary report for an incident with a Colorado radiography licensee. Utah Inspection, LLC (Colorado license 1043-01) reported to the (Colorado Department of Health (CDH)) on October 18, 2010 a stuck source/source disconnect for a radiography source. The job site was at a gas compressor station in De Beque, Colorado. Initial reports indicate the source was approximately 60 Ci of Ir-I92. Utah Inspection contacted the CDH at approximately 2:30 pm on October 18,2010 to report the incident. The licensee reported that while performing a radiography shot, the camera slipped off a wet pipe and landed on the guide tube causing a crimp in the tube which prevented the source from being retracted. The licensee extended the boundaries around the source and maintained surveillance of the source. The licensee contracted with a local Radiation Safety Officer trained in source retrieval activities and was able to retract the source to the shielded position at approximately 7:15 pm on October 18, 2010. A member of the CDH responded to the incident scene as the retraction efforts were being completed. The RSO contracted for the source retrieval reported an estimated 138 mrem whole body, and the radiographer estimated doses at 50 mrem whole body for himself and 25 mrem whole body for his assistant. Individual overexposure does not appear to be an issue at this point for this incident. The individual from the CDH confirmed that the area was very isolated and the radiographer and assistant were able to maintain their distance from the source. Colorado Incident I10-13.
ENS 4755929 December 2011 16:40:00The following report was received from the State of Colorado Radioactive Material Unit via facsimile: This memo is to serve as a preliminary report for an incident concerning fixed nuclear gauges which were discovered at a Colorado scrap yard which is not licensed for that type of material. The Department (State of Colorado) was notified on December 28, 2011 that two gauges were identified at Rocky Mountain Recycling in Commerce City, Colorado. The initial notification indicated that they were both TN 5100 gauges (subsequently determined to be TN 5200 gauges) with an original activity of 20 mCi in 1986. Rocky Mountain Recycling currently has a Colorado provisional radioactive materials license (Colo. 9016-01) and is licensed for six sections of scrap pipe which are contaminated with NORM in the form of pipe scale. For normal operations, Rocky Mountain Recycling does not possess a radioactive materials license. The Department responded to Rocky Mountain Recycling on December 29, 2011. Two fixed gauges were at that location, both TN Technologies model 5200 gauges with serial numbers B1130 and B1131. Both gauges contain Cs-137 (verified using an ldentiFinder). Gauge B1130 contains 20 mCi as of December, 1986 and gauge B1131 contains 20 mCi as of October, 1986. The gauges were being stored in a steel drum away from public access. A wipe test was taken in the field on the drum prior to opening and no contamination appeared to be present. Wipe tests were also taken on the shutters of both gauges and no contamination appeared to be present. Both gauges appeared to be in good shape, there was some rust and weathering on the outside of the source housing but otherwise the source housing and shielding appeared to be in working condition. The gauges were found without a lock to keep the shutter in the closed position. One gauge (B1131) was found with the shutter partially opened. Gauge B1130 could not have the shutter completely opened due to the steel mounting frame being bent. Both shutters could be manipulated by hand. Rocky Mountain Recycling provided padlocks to lock the shutter in the closed position for both gauges. Dose rate measurements were taken around the shielding of the gauges. On contact, both gauges measured approximately 2.5 mRem/hour. With the shutter open, the highest reading in the beam of gauge B1130 was approximately 60 mRem/hour on contact, 15-20 mRem/hour at approximately 1 foot, and 3-3.5 mRem/hour at approximately 1 meter. With the shutter open, the highest reading in the beam of gauge B1131 was approximately 70 mRem/hour on contact, 10 mRem/hour at approximately 1 foot, and 1.5 mRem/hour at approximately 1 meter. Around the drum the gauges were stored in, the highest reading on contact was 1.5 mRem/hour, the highest reading at one foot was 0.3 mRem/hour, and the highest reading at 1 meter was 0.08 mRem/hour. Colorado Report Number: I11-23
ENS 5002911 April 2014 21:29:00The following was received from the State of Colorado via email: The State of Colorado needs to report a missing/lost portable gauge. The licensee is AG Wassenaar, Inc. (Colorado license number CO 212-01). The gauge is a Troxler model 3430, serial number 36856 with 333 MBq (9 mCi) of Cs-137 and 1.63 GBq (44 mCi) Am-241:Be. The technician who was using the gauge was working at one job site and then drove to a 2nd job site. The technician cannot remember if he placed the portable gauge in the transportation box or not, and whether or not the gauge was secured for transport appropriately. When the technician arrived at the 2nd job site at approximately 1430 MDT on 4/11/14, he noticed that the gauge was missing. The technician and radiation safety officer have traveled the area between the two job sites and were not able to locate the missing gauge. The licensee reported the missing gauge at approximately 1750 MDT on 4/11/14. The investigation by the licensee and the Department (State of Colorado) is ongoing.

ENS 5047922 September 2014 13:06:00The following report was received from the State of Colorado via email: The State of Colorado received a report this morning from a medical licensee of a misadministration. The licensee reported that at 1230 (MDT) on Saturday 9/20/14, the technologist injected a patient with a bulk dose of Tc-99m instead of a (smaller) patient dose. The initial estimate for the amount injected is 140 mCi. The initial potential whole body dose is 6-7 rem with 30 rad as the highest potential organ dose (upper intestine). The investigation is ongoing. Additional information regarding the intended patient dose will be provided when available. The attending physician and patient will be informed by the licensee. 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 5141722 September 2015 17:22:00The following report was received from the State of Colorado via email: On September 22, 2015, during a routine inspection at Colorado licensee St. Thomas More Hospital and Progressive Care (license CO 397-01), (Colorado State) inspectors noted multiple areas with contamination. Upon further investigation, the inspectors learned a patient earlier in the day was undergoing a diagnostic test involving nebulized Tc-99m DTPA for a lung scan. The patient began coughing and pulled off the mask during administration and coughed, spreading the contamination in the diagnostic area. The patient began to require elevated levels of medical care and nursing staff and nuclear medicine staff may have been contaminated while caring for the patient. Arrangements were made to transfer the patient to a different medical facility via helicopter. The second facility was notified and nuclear medicine technologists surveyed the helicopter and patient upon arrival with no contamination found. Reporting requirement: 10 CFR 30.50(b)(3); Colorado Part 4, Section 4.52.2.4 Cause and corrective action: patient intervention. St. Thomas More has closed the affected areas to allow for decay. Surveys will be performed in affected areas prior to re-opening for additional patients. A full report of investigation and evaluations will follow within the next 30 days. Incident identification: CO15-I15-27
ENS 5167020 January 2016 18:32:00The Department (Colorado Department of Public Health and Environment (CDPHE)) received a phone report from the Radiation Safety Officer for Saint Joseph Hospital regarding a medical event involving the HDR (high dose rate therapy). A patient was scheduled to receive three fractions of HDR treatment in November, 2015. It is believed the second fraction caused the medical event on November 9, 2015. In December, the patient reported to their primary care physician, burns to the leg. The authorized user was notified in December by the patient and/or primary care physician. The authorized medical physicist and radiation safety officer were notified of the event on January 19, 2016 and notified CDPHE on January 20, 2016. The intended dose to the treatment site was 6,000 cGy with all of the intended dose being delivered to the patient's leg. The preliminary cause was an error with the transfer tube-applicator interface, but the licensee is still conducting an internal investigation. The Department is expecting a full report from the licensee within 15 days and preparing for a visit to investigate the event.

ENS 543736 November 2019 16:34:00The following was received from the Colorado Radioactive Materials Unit via email: On 11/6/19, the Colorado Department of Public Health and Environment was notified of a potential reportable contamination event. On 11/1/19, approximately 12 hours after an I-131 MIBG (meta-iodobenzylguanidine) administration (293.6 mCi) on 10/31/19, the patient's catheter was dislodged (while asleep). I-131 contaminated urine spilled out of the catheter and contaminated the patient, bed, bedding, and floor under the bed. Most of the spill was located under the bed. The patient was decontaminated after the spill was identified and has since been released from the facility. After the patient was released, the extent of the spill was identified by the licensee. The treatment room has not been released for unrestricted use as of 11/6/19. Dose rates taken by the licensee indicate the potential for greater than 5 times the ALI (annual limit on intake) prior to decontamination efforts.

ENS 5593511 June 2022 19:44:00The following is a summary of information received from the Colorado Department of Public Health and Environment by e-mail: Two armed individuals broke into the Colorado location for Acuren Inspection, Inc. The licensee described this event as part of a chain of local break-ins. The individuals were able to access the vault which contained the radiography cameras but were unsuccessful in accessing the radiography cameras stored within a secure container in the vault. It appears that no radioactive materials were accessed or removed in any way from the licensee's storage area. LLEA (Denver Police) was dispatched and responded to the facility. According to the (National Source Tracking System) (NSTS), as of June 11 the licensee is currently in possession of six Ir-192 sources, ranging from 98 curies to 24 curies.

ENS 5596627 June 2022 17:07:00The following information was received from the state of Colorado via facsimile: On June 24, 2022, a patient was prescribed 1.45 GBq (39.2 mCi) of Y-90 microspheres (TheraSphere) to the right lobe of the liver, lobe estimated size of 474 grams, for a target dose of 148 Gy. However, imaging after the administration indicates that the dose was incorrectly delivered to the left lobe of the liver, lobe estimated size of 283 grams, for an estimated delivered dose of 240 Gy. The preliminary cause is based on the patient's anatomy with the left hepatic branch close to the intended treatment site. The physician's office is reaching out to the patient to notify them but has not been able to at the time of this initial notification.
