The following report was provided by the Tennessee Division of Radiological Health via email:
"At approximately 2105 [EDT] on the night of July 12th, using our local access control program (i.e., Canberra HIS20) and a DMC 3000 series electronic dosimeter, an Erwin Resin Solutions employee was exiting the Radiological Controlled Area when he received a message stating that he had exceeded his TEDE [Total Effective Dose Equivalent] limit. According to the access control program, a dose of 10002.2 mrem was received. The employee was immediately removed from the area and follow up surveys were conducted. Surveys indicated that general area dose rates were 2-15 mr/hr and that the highest individual package dose rate was 45 mr/hr. The individual had been in the area for approximately 0.47 hours and he recalls at one point looking down at his dosimeter to see a display of 2.4 mrem. The employee's TLD has been pulled and sent off to Mirion for an emergency read, results are expected within 24-48 hrs. The individual will remain out of the RCA until the investigation has concluded.
"Access records have been pulled from the HIS20 program and the doses given were not reflective of a normal entry. A START READ of 0 mrem was given and an END READ of 0 mrem was also given. A GAMMA COMPONENT READ of 10002.2 mrem was given but should have been the same as the END READ which was 0 mrem. All indicators lead to a faulty electronic dosimeter, the dosimeter in question is being sent to our instrument department for further evaluation.

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LOST/STOLEN TROXLER DENSITY GAUGE
At approximately 1745 EDT the State of Florida was contacted by the Radiation Safety Officer for MC Squared, Inc. The RSO reported a probable stolen Troxler gauge. Model number 3411B Serial Number: 13563. The company vehicle was parked at a contractor's site at the intersection of Anderson and West Waters Avenue in Tampa, FL. The gauge and packaging were chained and locked to the bed of the truck and was also strapped down. When the technician came out around 1600 EDT he noticed it was missing. They were only parked in that area between 30 minutes to an hour and the lock is also missing. The Hillsboro County Sherriff's office was notified. A report was filed by the Hillsboro County Deputy, Report Number: 15-441038. When the report is completed it will be available to the State of Florida.
The Troxler gauge sources are 40 mCi of Am/Be, and 8 mCi of Cs-137.
State of Florida Incident Number: FL15-068.
The State of Florida is continuing to investigate this event.
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.

The following report was received from the North Carolina Department of Health and Human Services via email:
"Narrative event description: I-125 Prostate seed implant medical event occurred when physicist ordered the incorrect activity and number of seeds. The patient plan had the correct planned activity, but when the order was placed with air kerma, the wrong activity was ordered and subsequently implanted to the patient.
"Event date and notification date: Implanted 7/9/15. Identified and reported the medical event 7/13/15.
"Phone Call received from Physicist to NC RAM [North Carolina Radioactive Materials] Branch at 1246 [EDT] on 7/13/15.
"Cause and corrective actions: Incorrect calculations and human error in conversion from air kerma to activity; [The licensee] ordered and implanted [the] wrong activity.
"Notifications: NC RAM Branch notified 7/13/2015
"Indicate if there are any generic implications: Lack of attention to units and procurement procedures for seeds.
"Source/Radioactive Material: Iodine 125 brachytherapy seeds from Theragenics Corporation
"Procedure administered; dose intended and actual dose administered; isotope and activity administered; target organ: Prostate Seed Implant, Intended Dose 144 Gray or 23.48 mCi (71 seeds), Implanted Dose of 31.299 mCi (75 Seeds), ~33% overdose based on activity alone (physicist reported 28%), I-125 seeds and 31.299 mCi administered, prostate was target organ.
"[The] patient and Referring Physician were notified 7/13/15.

"Unit 2 Reactor automatically tripped during Unit start up following a maintenance outage. The first indication of the reactor trip was the annunciator Reactor Trip by Turbine Trip. There were no complications following the trip and Unit 2 is stable at Hot Shut Down. Decay Heat Removal is being maintained by dumping steam to the Main Condenser. Steam Generator water level is being maintained by the Main Feedwater system.
"At the time of the Reactor Trip, Overspeed Protection Circuitry (OPC) Test was being performed on the Unit 2 Main Turbine. The SOV Turbine Trip annunciator was received. The cause of the reactor trip is under investigation.
"This notification is being made pursuant to 10 CFR 50.72(b)(2)(iv)(B) for 4-hour notification of Reactor Protection System activation. The Plant responded as expected for the trip. The NRC resident has been notified of the event.
"There was no radiation release due to this event, nor were there any personnel injuries or contamination events."
The licensee has notified the NRC Resident Inspector. |

"On 7/21/2015, at approximately 1453 Pacific Daylight Time (PDT), while performing quiet testing of the early warning system, a Pacific Gas and Electric (PG&E) Telecommunications Technician identified that a single emergency response siren was making a full sound output when it should not have been. PG&E Technicians took action and deactivated the single siren. The siren sounded for approximately 1 minute. As a result, this issue is being reported under 10 CFR 50.72(b)(2)(xi) for notifications to other offsite government agencies as the licensee notified the County of San Luis Obispo of the siren deactivation. The San Luis Obispo County Sheriff Watch Commander has been notified of the need to implement alternate means of alert and notification for the areas affected by the deactivation of the single siren. This was accounted for in pre-planning efforts and neither the utility nor 911 received any calls [from the public] related to this matter. The source of the activation signal has not been determined and is being investigated.
"There was no impact to the health and safety of the public as a result of this event as the offsite response capabilities remain functional with a single siren failure. The site is operating normally with no emergency conditions present. The NRC Resident Inspector has been notified." | |
