AGREEMENT STATE REPORT - TROXLER GAUGE DAMAGED AT CONSTRUCTION SITE

The following report was received from the North Carolina Department of Health and Human Services via email:

"North Carolina Licensee ECS Carolinas, LLP, License Number 092-0253-1 reported that a Troxler Model 3440, S/N 24665 Moisture Density Gauge had been damaged on July 10, 2017 at a construction site in Chapel Hill, NC. The gauge contained 8 mCi of Cesium-137 and 40 mCi of Americium-241. An approved technician backed up a company vehicle over the gauge. North Carolina Radiation Protection immediately dispatched an inspector on site to perform a reactive inspection same day. Event Date and Notification Date: July 10, 2017. Licensee had cordoned off a 15+ foot barrier around the vehicle and the gauge. Surveys taken at various distances from the gauge and on contact confirmed that the sources were intact and shielded in the gauge. The gauge sustained minimal damage to the guide rod and the source rod was not extended at the time of the incident. No other local or federal authorities were contacted for this event. The gauge was returned to the manufacturer for repair or disposal. A 30-Day Report is pending from the licensee and follow-up information will be provided. NC Event Report Tracking Number: 170026.

LOST CHEMICAL AGENT DETECTOR

The following report was received via email:

"During routine maintenance and inventory of the equipment one of the devices could not be accounted for during the evolution. An extensive internal investigation was conducted by the local command and thorough search for the missing device was conducted and ultimately concluded the device was not located and determined lost. The device was declared lost 5 July 2017.

"Naval Surface Warfare Center Crane reported the lost chemical agent detector containing a 10 millicurie Nickel-63 (Ni-63) source. As the quantity exceeds 10 times the quantity listed in 10 CFR 20 Appendix C, a telephone notification is required to the NRC within 30 days per 10CFR20.2201. A follow up written report will be submitted within 30 days after this initial notification.

"The device, Serial Number 09-4326, contains one foil-sealed source of Ni-63 and does not to exceed 10 milliCuries. The source is Eckert and Ziegler Isotope Products Laboratories Model NER-004. The Ni-63 source is encapsulated in a 304 steel cup with 1 millimeter wall thickness. The source cup is fitted into a ceramic enclosure of 10 millimeter wall thickness. The Ni-63 source is sealed in a detection chamber located inside the housing of the detector. The device has two radioactive material labels to warn personnel of the radioactive source inside the device. One label is on the outside of the device and the other is on the detector housing on the inside of the instrument.

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.
