Security of Radioactive Materials
- Radioactive materials must be controlled so that unauthorized
persons do not have access. Therefore, stock vials, test samples, and radioactive
wastes must be locked up or in a locked laboratory when
unattended, even for a short time.
- When visitors are not accompanied by authorized laboratory
personnel, find out who they are and why they are there.
- If radioactive materials must be stored in refrigerators
or freezers outside of the laboratory, the refrigerator or freezer must be
locked at all times.
- Do not store radioactive materials, sources or waste in common
rooms, i.e., counting rooms, centrifuge rooms and cold rooms.
