A Palladium-103 (Pd-103) brachytherapy see … A Palladium-103 (Pd-103) brachytherapy seed (Theragenics Model 200 nominal activity 1.5 mCi) broke when the Mick shielded magazine was removed from the applicator. An activity of (approximately) 0.5 mCi for the lost portion of the seed was calculated by measuring the remaining portion of the seed. It was not recovered and presumed to have washed down a sink drain. The seed was broken and lost October 15, 2014 around 0945 (EDT). The incident was discovered around 1645. Surveys of the area for the lost portion returned no radiation above background. Contamination from the seed is remote because the Pd-103 is coated on (adhered to) a graphite pellet. No personnel radiation exposure data available. It is unlikely the person involved received measurable dose.</br>The process for removing the cartridge at the end of a procedure will be reviewed to reduce the chance of this happening again.</br>The licensee contacted NRC Region 3 DNMS personnel.see contacted NRC Region 3 DNMS personnel. +
