AGREEMENT STATE REPORT - RADIATION WORKER RECEIVES HIGH DOSIMETRY READING
The following report was received from the Arkansas Department of Health via email:
"The RSO reported at 1100 [CST], on November 14, 2018, that the dosimetry provider had reported to the licensee one radiation worker badge had received a possible exposure of 9,000 mR for the month of October. The dosimetry provider has stated the exposure was a dynamic exposure with atypical exposure to the badge.
"The licensee began to investigate the cause of the high reading. The worker had worked with other employees and had not worked independently during the month. Other workers had routine exposures for the month.
"The licensee requires workers to wear SRD's [Self Reading Dosimeter] while working in the restricted area. The worker's cumulative reading for the time period was 200 mR. The worker's ring badge had routine exposure readings.
"During investigation by the licensee, there was no recollection of the badge being separated from the worker during the month. During off hours, all dosimetry is stored with the worker's lab coats outside the restricted area.
"The licensee develops PET [Positron Emission Tomography] radionuclides for radiopharmaceutical research and development.
"Since the time period of the exposure cannot be determined, the Arkansas Program is reporting this event under RH-1502.b. of the Arkansas Regulations equivalent to 10 CFR 20.2202(b)(1) of the NRC Regulations.
"The licensee and the State continue to investigate.
"The State of Arkansas will update when additional information is known.
"Arkansas event number AR-2018-006."
* * * UPDATE ON 12/14/18 AT 1535 EST FROM STEVE MACK TO BETHANY CECERE * * *
The following update was received from the Arkansas Department of Health (Department) via email:
"The licensee provided a written report dated November 15, 2018, outlining the investigation performed to verify the overexposure reported.
"This report restated the requirements of additional dosimetry worn by the worker with no significant indication exposure above routine doses. The report also indicated that at no time during the month was contamination detected when conducting personnel surveys leaving the restricted area. The licensee continues to believe that the dose was only received by the badge and not to the whole body of the radiation worker.
"The licensee submitted its own dose estimate on December 3, 2018, in which the licensee calculated a possible contamination event of the badge that would provide the dose yet exclude dose to other measuring devices and could evade detection when exiting the restricted area.
"The Department has taken this dose estimate into consideration and is requesting that the October, 2018 dose for the radiation worker be reduced to 250 mrem.
"The Department considers this event closed."

AGREEMENT STATE REPORT - MEDICAL EXPOSURE READ AS OCCUPATIONAL EXPOSURE
The following report was received via e-mail:
"On Wednesday, November 14, [the University of Miami Radiation Safety Officer (RSO)] received an Occupational Exposure Report from Mirion Technologies indicating that for wear dates July 1 through July 31, 2018, x-ray technologist [redacted] received the following doses: Deep: 8328 mR, Eye: 8328 mR, and Shallow: 8328 mR.
"Upon interviewing Mr. [redacted], in the presence of his supervisor, Mr. [redacted] indicated that he had a therapeutic Nuclear Medicine procedure for hyperthyroidism during the month of July in one of our facilities. Upon review of his medical records it was confirmed that Mr. [redacted] received 24 microCuries of iodine-131 for an uptake scan on July 10, 2018, and a therapeutic dose of 28.9 mCi of iodine-131 on July 17, 2018. It was noted that Mr. [redacted] wears his dosimeter high on the collar of his scrubs, very close to the area overlying his thyroid and continued to wear it throughout the period in question. Based on this information it is [the RSO's] professional judgement that this dose does not constitute an Occupational Dose but is rather a medical dose, and he will be requesting that his dosimetry provider remove it from Mr. [redacted] Occupational [dose]."
