Here is a checklist you can use to gauge your lab's performance in some of the practices that make work with radioactive materials safer. See the training form on the reverse.
Workers know how to get help in an emergency.
Tritium users perform contamination surveys using wipe tests counted in liquid scintillation. The lab keeps a written record of the radionuclides and activity placed into each waste container. Each worker receives annual refresher training in radiation safety policies and practices. A list of current radiation workers is posted in the laboratory. Each radiation worker registers before the worker starts using any source of ionizing radiation.
