The following was received from the
Massachusetts Radiation Control Program (the "Agency") via email:
On 05/06/2022, at 1340 EDT, the Agency received a call from
RSO [Radiation Safety Officer] at Thermo Scientific Portable Analytical Instrument, Inc. (the `licensee') reporting a leaking sealed source. The 20-year-old source/device (Thermo Scientific Portable Analytical Instruments, Inc.; Model XLi 969; Device s/n 5243; Source s/n EG-8804) is currently containing 0.12 mCi of
Fe-55 (original activity was 20 mCi on 04/07/2002). The
RSO received the leak test report on 05/06/2022 and he noticed that the source is leaking as 0.0058 microcuries of removal activity which is in excess of regulatory limits (0.005 microcuries). This device was sent to the licensee for decommissioning and was received from the licensee's customer on 04/21/2022. The source was removed from the device as part of decommissioning. There was no external contamination spread outside of the device or surrounding work area surfaces. The source will be secured and properly disposed of in accordance with the regulations.
