Types of Package Labels

There are three basic labels used to identify radioactive materials:

  • Radioactive White - I
  • Radioactive Yellow - II
  • Radioactive Yellow - III

All of the labels bear the distinctive trefoil symbol which is universal for the identification of radioactivity or radiation.

By looking at a package's label, one can determine the hazards associated with it without the aid of a radiation monitoring device.
