Reported to NYS DOH [New York State Department of Health] on 11/12/2013. A patient received two seeds for right breast radioactive seed localization when only one was intended. The patient had two marker clips, a cylinder clip marking a benign biopsy site and a coil clip marking a papilloma. It was intended for her to only receive one seed placed at the papilloma site, but the benign site was marked with a 0.252 mCi iodine-125 seed. A second seed (0.251 mCi) was then placed to mark the correct site. The unintended dose from the 0.252 mCi seed in place for 2 days was 0.61 Gy @ 0.5 cm. Root cause analysis is ongoing.
