| Title | Leaking CS-131 Brachytherapy Source |
| Event Description | 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. Washington Incident Number: WA-22-021 |
