The following was received from the
Illinois Emergency Management Agency (
IEMA or the Agency) via email:
On 10/12/2022, the Radiation Safety Officer [RSO] at Siemens Medical Solutions USA, Inc. (IL-01130-02), notified the Agency regarding a leaking Co-57 sealed source received on 10/12/2022 from the manufacturer, Eckert & Ziegler. The 15 mCi point source was opened and handled in a restricted area behind a small L-block. Upon removal from the packaging (noted as intact), the source was placed in a tungsten holder and was promptly leak tested by the RSO. Leak test results indicated contamination levels of 23,000 dpm [disintegrations per minute] on the source capsule and 140,000 dpm on the inside of the baggie in which the source was shipped in. Subsequent area and personal surveys were performed with no contamination noted. The source, baggie and a few tools used in the initial handling of the source were doubled bagged and remain secured at Siemens pending return to the manufacturer. The leaking source was reported to IEMA within 5 days as required in accordance with 32 Illinois Administrative Code 340.1260 and was then reported to the NRC as required. The investigation is ongoing.
