AGREEMENT STATE REPORT - LOST/RECOVERED MOISTURE DENSITY GAUGE
The following is a summary of information provided by the Colorado Department of Public Health and Environment (the Department) via email:
"On September 11, 2025, at approximately 1930 MDT, the Department received a phone call from the Jefferson County Sheriff's Office regarding a vehicle that was stolen in Silverthorne, CO. Within the vehicle was a InstroTek Model 3500 portable nuclear density gauge (SN:5664). The vehicle was involved in a police chase and eventually crashed on Interstate-70 East, near mile marker 258.
"Photos of the gauge were sent to the Department and the gauge was inside of the transport case, which did not appear to be damaged. Colorado State Patrol was also on scene and recorded a reading of 4mR/hr on contact of the transport container. Additional information about the meter that was used to record that value was not available at the time of the call as the scene was unfolding.
"At approximately 2114, the Department reached out to the Branch Manager of CTL/Thompson, Inc. The Branch Manager informed the Department that a technician was on route to retrieve the portable nuclear density gauge.
"At approximately 2138, the Jefferson County Sheriff's Office called and notified the department that the technician was now in possession of the gauge.
"The licensing information for the InstroTek Model 3500 was reviewed to verify that the surface readings taken at the scene did not exceed the expected dose rate.
"Based on the information provided by law enforcement, no exposures above public dose limits are expected. The department will follow-up with the licensee to verify the gauge was not damaged in the incident and review subsequent leak tests.
"Radioactive material summary: Make/Model: InstroTek, Inc. Model 3500 moisture density gauge radionuclide/activity: not more than 408 MBq (11 mCi) of cesium-137 and 1.63 GBq (44 mCi) of americium-241:beryllium. Serial Number: 5664."

AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE
The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:
"On September 12, 2025, the Department received a report of a stolen Troxler model 3440 moisture density gauge (8 mCi Cs-137, 40 mCi Am-241/Be). The gauge was stolen from a licensee vehicle outside of a hotel in Humble, Texas. The theft was witnessed [by a member of the public] but by the time police (Humble Police Department) arrived, the perpetrator was gone. The licensee personnel were not notified, and they called the police again. A written report was received at 0948 hours. The [licensee's] radiation safety officer stated they think the handle lock was in place; accordingly, there is no immediate threat to the general public.
"Additional information will be provided in accordance with SA - 300 reporting."
Texas incident number: 10227, NMED number TX250046
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.

AGREEMENT STATE REPORT - PACKAGE EXCEEDED EXTERNAL RADIATION LIMIT
The following is a summary of information provided by the Louisiana Department of Environmental Quality (the Department) via phone:
The licensee reported that a package received from the Colorado School of Mines, containing a 1.166 mCi Co-57 source (model MC07.122, serial number: 31.23, manufacturer unknown at the time of the report) had measured external dose rates of 50 mr/hr on contact and 0.2 mr/hr at 1 meter. When the external packaging was opened, it was discovered that the internal shipping container had been damaged. It is believed that the damage to the internal shipping container degraded the effectiveness of the shielding, resulting in the external radiation levels measured. The Department will follow-up with additional information as it is developed.
* * * UPDATE ON 09/15/2025 AT 1319 EDT FROM JAMES PATE TO ROBERT THOMPSON * * *
The following is a summary of information provided by the licensee via email:
The package was supposed to be an excepted package. The package was damaged. The package received contained one source with the lid off the transport container inside the package. The activity of the source initially reported was the current activity; the original activity of the source was 10 mCi. The source was manufactured by Ritverc JSC and is used in a Mossbauer spectroscopy device. The Colorado School of Mines is licensed by the State of Colorado, license number CO 627-01.

AGREEMENT STATE REPORT - LOST CONTROL OF SOURCE
The following information was provided by the Texas Department of State Health Services (the Department) via phone and email:
"On September 16, 2025, the Department was notified that on September 11, 2025, a radiographer was involved in a traffic accident while transporting an IR 100 radiography device containing a 45.7 curie iridium-192 source. The radiation safety officer (RSO) stated the radiographer hit another vehicle and then left the scene of the accident and went to their hotel. Someone provided the license plate number of the radiographer's truck to law enforcement. Law enforcement found the truck at the hotel, arrested the radiographer, and had the truck with the source transported to an impoundment yard. The truck was towed at 0300 CDT on September 12, 2025. The RSO was contacted by the impoundment yard, picked the truck up at 0830 that same morning, and returned the source to its storage location.
"The RSO stated that the locks on the darkroom door and the transportation box were still intact. The RSO does not believe any individual would have received an exposure due to this event.
"Additional information will be provided as it is received in accordance with SA-300."
Texas incident number: 10229
THIS MATERIAL EVENT CONTAINS A 'Category 2' LEVEL OF RADIOACTIVE MATERIAL
Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

AGREEMENT STATE REPORT - NON-LICENSEE IN POSSESSION OF LICENSED MATERIAL
The following is a summary of information provided by the Florida Department of Health (the Department) via phone and email:
On September 15, 2025, US Customs and Border Protection (CBP) identified a Troxler model 3430 moisture density gauge (S/N 20331, 8 mCi Cs-137, 40 mCi Am-241/Be) in a vehicle leaving the Port of Jacksonville. CBP held the vehicle and determined that the company, RQ Construction Co., was not licensed to possess a gauge with this level of radioactivity. CBP notified the Department of the incident and contacted Troxler and arranged for transport of the gauge to Troxler's facility in North Carolina. The Department has learned that the model 3430 gauge was sent for calibration and leak testing at Troxler by a Florida-licensed company in Tampa, FL.
The Department has learned that RQ Construction Co. recently purchased a Troxler 4950 soil density gauge. This model of gauge does not require a radioactive materials license for possession and use. Troxler is investigating how the model 3430 gauge was returned to an unlicensed company in Jacksonville, FL.
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.
