Security Principal Investigators (PIs) and lab personnel must ensure that check sources are secured from unauthorized use, transfer, tampering, or theft. Check sources must be secured by at least one of the following: • Keeping them under constant ‘line of sight’ surveillance by an approved user. • Locking the approved laboratory. • Placing them in locked, permanent storage (such as a cabinet with a lock) within the approved use or storage area. Any known or suspected loss or theft of sources must be reported immediately to EH&S. Inventory The PI is required tomaintain inventory records. EH&S provides an Inventory and Usage Log with each check source. The Inventory and Usage Logs should be used by laboratory staff to track the check source inventory. EH&S staff can provide a copy of the laboratory’s current inventory to assist with quarterly inventory checks. Sources are inventoried at least annually by EH&S staff. If a source cannot be located, contact EH&S immediately. Equipment A calibrated radiation detection meter may be required for verification of sources. Contact EH&S for the correct type of meter to use with your sources. Storage The location of each sealed source is recorded by the radiation safety staff to facilitate leak testing and inventory requirements. If it becomes necessary to move a check source to a new location, either permanently or for an extended period of time, EH&S must be notified prior to the move. Note: Any lost or missing source must be reported immediately to EH&S! Note: Storage cannot be used to avoid disposal fees!
