Attachment 02 Current Sources and Shipments over the past 3 years.pdf

This document provides a comprehensive record of radioactive material (RAM) sources and patient RAM waste shipped by a medical facility over a three-year period (2023-2025), along with current sealed sources held in inventory.

The 2023 shipments included six RAM sources (primarily Gd-153 and Co-57 isotopes used in medical imaging devices manufactured by Siemens) with activities ranging from 1.00E+01 to 5.00E-02 mCi, manufactured between October 2020 and December 2020. Patient RAM waste shipped in 2023 totaled 0.5346 cubic feet across nine plastic nalgene containers, primarily containing Yttrium-90 with activities measured in scientific notation. In 2024, patient RAM waste was not shipped but instead decayed in storage and disposed as normal trash at the facility. The 2024 shipments included 25 plastic egg containers and 6 stock vials containing Lutetium-177 and Lutetium-177 isotopes with total activity of 2.076 mCi. For 2025, eight RAM sources were shipped (primarily Ge-68, Co-57, and Gd-153 isotopes) with activities ranging from 5.00E-02 to 1.08E+00 mCi. Patient RAM waste in 2025 totaled 0.134 cubic feet and 0.0484 cubic feet across multiple containers, with activities measured between 1.65E-25 and 5.73E-37 mCi. The facility currently maintains approximately 50 sealed sources available for shipment, with calibration dates ranging from 2013 to 2025 and half-lives varying by isotope (Ca-137, Ba-133, Co-57, Ge-68, and others).
