CALIFORNIA AGREEMENT STATE REPORT - STOLEN NUCLEAR GAUGES
The State provided the following information via email:
"At 0830 on July 18, 2005, [NAME DELETED], RSO for the licensee called to report that two model MC-3 gauges (each containing nominally 10 mCi of Cs-137 and 50 mCi of Am-241) were stolen from the secured temporary job storage site in Yucaipa, CA . There were three gauges at this site, but the model MC-1 gauge (an older gauge) was not taken. The licensee last saw these gauges when the job-site was shut down for the weekend, approximately 1700 on July 15, 2005. This morning [07/18/05], in preparation for returning to work, it was noted that two gauges were missing at approximately 0630-0700 hours [PDT]. The RSO is in transit to the job-site, to meet the local police, and will provide more details as he gets them. The licensee intends to post a reward in the Press-Enterprise newspaper in the Riverside area."
State 5010 Report No.: 071805
* * * UPDATE FROM STATE (GREGOR) TO M. RIPLEY 1839 EDT 07/18/05 * * *
The State provided the following information via email:
" The window in which the gauges were stolen was 7/16-18/05 instead of 7/15-18/05 as indicated on our form. Also, we have been informed that there was other construction equipment stolen in addition to the two gauges. We have been informed in the past by law enforcement in the area that there is a ring who apparently raids construction sites stealing construction materials for resale in Mexico. Don't know if this is the situation in this case."

ALABAMA AGREEMENT STATE REPORT - IMPROPER USE AND SHIPMENT OF NUCLEAR GAUGE
The State provided the following information via facsimile:
"Description of Event: A dredging company using GL devices in Alabama illegally, removed and shipped a device containing a 200 milliCuries cesium 137 source to Ronan Engineering Company in Kentucky for repair. The shutter was not locked in the closed position. The owner had painted over the marking and labeling on the source holder so that they were illegible. The dredging company has hired a consultant to reconstruct the incident and try to determine any possible exposures received.
"Additional information will be submitted after the investigation is completed."
The following, additional information was obtained from the State via telephone:
Dredging Company: Inland Dredging, Co. based in Dyersberg, TN, doing work in the vicinity of Jackson, AL
The gauge is currently at Ronan Engineering Co., Florence, KY
Event date is unknown, but the State was notified on the evening of 7/18/05. |

MEDICAL EVENT - DELIVERED DOSAGE EXCEEDED PRESCRIBED DOSAGE
"On Wednesday July 20, 2005 it was discovered, during a routine audit of the Nuclear Medicine records, that two patients were administered I-131 in amounts exceeding 30 microcuries without a written directive. Furthermore, the doses fell more than 20% outside the prescribed dose range as set by the Authorized User (AU) physician. Below I will discuss the particulars of each administration.
"1. Patient #1: 25 year old female was administered 31 µCi of I-131 Sodium Iodide (Nal) on 18 July 2005 without a written directive prepared or signed by the AU previous to administration. The purpose of the study was to ascertain the thyroid uptake fraction and image the thyroid tissue. The prescribed does range, as set by the AU, was 8 to18 microcuries. This dose was 72% higher than the maximum dose allowed by the AU for this diagnostic procedure. (The patient's actual 24-hour thyroid uptake fraction was 27.5%).
"2. Patient #2: 61 year old female was administered 42 µCi of I-131 Nal on 14 July, 2005 without a written directive prepared or signed by the AU previous to administration. The purpose of the study was to ascertain the thyroid uptake fraction and image the thyroid tissue. This dose was 133% higher than the maximum dose allowed by the AU for this diagnostic procedure. (The patient's actual 24-hour uptake fraction was 14%).
"Dose Estimates From These Procedures
"1. Patient #1: Using data found in NUREG CR-6435 "Radiation Dose Estimated from Radiopharmaceuticals" we estimate the following doses for the (a) Whole Body: 1.209 rem, and (b) Thyroid (target organ) 40.3 rad
"2. Patient #2: Using data from NUREG CR-6345 and from other sources we estimate the following dose for the (a) Whole Body: 1.638 rem, and (b) Thyroid: 17.6 rad." |
