AGREEMENT STATE MEDICAL MISADMINISTRATION

The South Carolina Department of Health and Environmental Control was notified on Friday, June 04, 2004 of a possible medical rnisadministration notification which was reported by the Radiation Safety Officer for the Cancer Center of the Carolinas. A Cs-137 brachytherapy radiation dose was administered to a patient where the calculated administered dose differed from the prescribed dose by more than 20%. This apparently occurred when the radiation source was not fully extended to the end of the application catheter. The event is under investigation and updates will be made through the national NMED system as they become available.

COLORADO AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE

The following information was received by facsimile:

"At approximately 11 am on 6/5/04, a watering truck on a housing development construction project near Fort Collins, Colorado (County Roads 11, and 52), ran over a Troxler moisture density gauge (Troxler model 3430; Serial # 28846) owned by Terracon (Colorado Specific License #664-02). The gauge was being used for soil compaction measurements but was in the safe (up) position when it was run over. The technician responsible for using the gauge was reported to be in close proximity to the gauge at the time of the incident but may have had the gauge to his right and not in direct frontal view. As a result of the incident, the index rod was knocked off and the source rod above the unit casing was bent at a 90 degree angle but remained attached to the unit. The gauge casing was described to be mostly intact (i.e. not fully crushed) with the exception of damage to the display. Discussions with the RSO indicated that the gauge source was believed to have remained within the internal shielding following the incident.

"The RSO for Terracon reported to the scene at approximately 11:50 am (6/5/04) and performed initial radiation measurements of the gauge. The initial radiation measurements on scene indicated values of approximately 1.0. millirem/hour on/near the surface of the gauge and 0.2 [millirem/hr] at 1 meter. The gauge was placed in the transport case and returned to the Terracon main offices located at 301 North Howes, Fort Collins, CO, 80521. The damaged gauge (in the case) was placed in an outbuilding located near the main office and was secured and the area posted per the RSO. The Department mandated that a leak test be performed prior to shipment of the gauge to a repair facility - results are pending.

"Based upon the nature of the incident and the position of the source and rod as, described by the RSO, the source is believed to be intact with no release to the environment or personnel or public exposure. A written report from the licensee is expected within 30 days."

DAMAGED MOISTURE DENSITY GAUGE

An equipment operator backed up a vehicle (Bobcat) over a moisture density gauge at a construction project site located near the intersection of White Gate and West Clay streets in Saint Charles, Missouri. The density gauge was damaged but the gauge probe (rod) containing the source was inserted into the ground during the accident. The licensee followed emergency procedures and contacted their contractor to perform radiation surveys of the area. Initial measurements indicate that the sources are not leaking. Further leak tests will be performed on the damaged gauge. The licensee is planning on packaging and shipping the damaged density gauge to the manufacturer. The moisture density gauge is manufactured by Humboldt, series 5001 containing 10 millicuries of Cs-137 and 40 millicuries of Am-241:Be.

OFFSITE NOTIFICATION MADE DUE TO INADVERTENT EMERGENCY SIREN ACTUATION

"One emergency response siren (Number 10 Brunswick County) located in Southport, NC inadvertently actuated at 0205, apparently due to a lightning strike, and was silenced at 0312. The Brunswick County, New Hanover County and North Carolina State Emergency Operation Centers (EOC) were notified of the inadvertent actuation. The Brunswick County 911 Center received calls from local residents reporting the siren actuation.

"Initial Safety Significance Evaluation: Minimal safety significance. The loss of the single siren will not significantly impact the public notification system. The remaining sirens in both Brunswick and New Hanover Counties have been verified to be operable.

"Corrective Actions: The siren was silenced at 0312 on June 10, 2004. The cause of the inadvertent actuation will be determined and repaired."

The NRC Resident Inspector was notified of this event by the licensee.
