MEDICAL EVENT - PATIENT UNDERDOSE
The following information was obtained from the licensee in accordance with Headquarters Operations Officers Report Guidance:
On September 29, 2022, a patient was administered an I-131 treatment to the thyroid. The patient did not receive the additional administration of Thyrogen, a hormone meant to enhance the uptake of I-131 to the thyroid. This resulted in dose delivered to other areas of the body and an underdose to the thyroid of preliminarily greater than 20 percent. Additional preliminary calculations showed that the bladder received approximately 17 Rem and the patient received a whole body dose of 39 Rem.
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 - LEAKING CS-131 BRACHYTHERAPY SOURCE
The following information was received via email from the Washington Office of Radiation Protection:
"On 11/2/2022, a licensee, IsoRay Medical - License Number: WN-L0213-1 reported a Cs-131 Brachytherapy source, model CS-1, leaking at customer's facility. A customer detected contamination on equipment used during a procedure with Cs-131 seeds. The customer was not initially able to identify the isotope of the contamination using their equipment, however they were able to perform a half-life estimation using dose measurements on a collimated container loaded with all the contaminated items from the procedure. The decay rate was roughly in line with Cs-131. The customer indicated that as part of their own procedures, the order, which arrived as a non-sterile mick pig, was opened and surveyed. No contamination was found at that time. A thorough investigation is ongoing."
