The following information was provided by the State via facsimile:
On Wednesday, April 19, 2005 while loading a Pd-103 seed into the Mick applicator, the applicator jammed. When the operating room technician attempted to get the seed loose, the seed broke. This spread a small amount of radioactive contamination onto the table, which was cleaned up by the RSO and dosimetrist. The applicator was found to be contaminated. It was put in a plastic bag, placed behind lead shielding and locked in the Nuclear Medicine hot lab. The activity of the Pd-103 seed was 1.578 mCi (millicuries). According to the licensee, there was no overexposure, contamination, or intake of radiation by anyone present in the operating room. The patient was treated, as per the prescription after borrowing a Mick applicator from another hospital.
The licensee notified DHFS on April 20, 2005. The licensee also contacted their consultant and their MIC applicator distributor regarding the event. A replacement applicator is being sent and the contaminated applicator will be allowed to decay before servicing.
The licensee has developed, an action plan for this event based on possible causes:
1. Look into the possibility of having the MIC applicator on a preventative maintenance schedule.
2. Change the sterilization procedure such that central supply does the cleaning of the applicator, not the OR technician.
3. Set up a 'core' group of OR technicians who are involved in their procedure, and document their education.
A voluntary MedWatch form was sent in to the FDA.
Wisconsin Radiation Protection Section plans on investigating this event.
