AGREEMENT STATE REPORT - TROXLER GAUGE DESTROYED BY BULLDOZER

The following was received from the Illinois Emergency Management Agency via email:

"The Illinois Emergency Management Agency (IEMA) communications center was notified at approximately 1942 [CDT] on 5/11/20 by the radiation safety officer for Testing Service Corp., license number IL-01178-01, to advise that a gauge user operating a Troxler model 3440 was struck by a bulldozer. The gauge user is reportedly fine, but the gauge was destroyed. The density gauge, serial number 72404, contains 8 mCi of Cs-137 and 40 mCi of Am-241/Be. Reportedly the source rod remained intact and both sources were identified and recovered into a lead drum. The licensee does possess a Geiger Muller survey meter and reported an external survey rate of 0.4 mR/hour on the outside of the drum (0.0 mR/hour is the reported background). The incident occurred at the southeast corner of Vollmer and Harlem in Matteson, IL. The sources were transported back to the licensee's facility. Agency inspectors are meeting with the licensee at 0700 [CDT] on 5/12/20 to verify the recovery of both sources, perform gross leak tests, advise on appropriate follow-up actions, and perform a site survey in Matteson. The licensee has already been in contact with the manufacturer for advice and instructions for returning the sources."

AGREEMENT STATE REPORT - LOST GAUGE

The following is a summary of an email received from the state of Florida:

At approximately 2030 EDT on 5/11/2020, a Troxler density gauge (serial number: 28189) fell off the back of one of the licensee's trucks because the chain securing the gauge's case was not properly attached. The gauge has not been located at this time. The gauge contains an 8 milliCurie Cs-137 source and a 40 milliCurie Am-241 source. Nearby police departments, the US Department of Transportation, and the Florida Department of Environmental Protection have all been notified.

Florida Incident Number: FL20-057

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 - PATIENT UNDERDOSE

The following is a summary of an email received from the state of Florida:

A patient underdose occurred during a Y-90 TheraSphere treatment at the licensee on 5/11/20. The patient was prescribed 2.48 GBq of Y-90, but only received 1.86 GBq (75% of the prescribed dose). The underdose was caused by the catheter being displaced during patient movement.

Florida Incident Number: FL20-056

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.

AGREEMENT STATE REPORT - RADIATION LEVEL ON PACKAGE EXCEEDS DOT LIMITS

The following was received via email:

"On May 11, 2020 the licensee received a 10 gallon drum that fell outside of the Department of Transportation (DOT) dose rate level limitations. The package came from Cadman Materials, Inc. in Vancouver WA. The material inside is a gauge with a Cs-137 sealed source inside with an activity of 100 millicuries (3700 MBq). The package was shipped as UN2915, Radioactive Material Type A Package with Yellow-II labeling and a Transport Index of 0.1. Upon survey at receipt, the container exhibited dose rates of 3.4 rem/hr on contact, 240 mrem/hr at 12 inches, and 18 mrem/hr at 3.3 feet. The delivering carrier, and the client, Cadman Materials, have been notified. The Pennsylvania Bureau of Radiation Protection will update this event as soon as more information is provided."

The event is reportable per 10 CFR 20.1906(d)(2).

AGREEMENT STATE REPORT - NUCLEAR GAUGE BROKEN LOCKING MECHANISM

The following was received by the state of Texas via email:

"On May 12, 2020, the Agency [Texas Department of State Health Services] was notified by the licensee that the locking mechanism on a Endress Houser nuclear gauge model number FQG61 had broken off the gauge housing preventing them from locking the shutter in the closed position. The gauge contains a 100 millicurie (original activity) cesium-137 source. The shutter operates normally. The licensee reported the gauge will not present an exposure risk to any individual. The licensee stated it is in the process of trying to schedule repairs to the gauge. Additional information will be provided as it is received in accordance with SA 300."

CONTROL ROOM ENVELOPE INOPERABLE

"At 1329 EDT on May 19, 2020, it was discovered that the main control room (MCR) envelope was inoperable due to a control room envelope (CRE) door being found ajar; therefore, this condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v). The CRE door was closed, restoring the MCR envelope to operable at 1331 EDT. There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."
