Semi-annual unannounced off-hour security inspections are conducted. “Off-Hours” are defined as 5:00 pm –8:00 am, lunch-time (11:00 –1:00) and weekends. All radioactive materials must be secured from unauthorized access or removal when not under constant surveillance. This can be achieved by making sure the laboratory is locked when nobody is in the lab or by locking all the radioactive material (including waste) within the lab in lockable refrigerators, freezers and cabinets.
