5-7. Application of Mixed Labels (49 CFR 172.403(e))
Radioactive materials with other hazardous characteristics also must be labeled with other labels as required according

a. Radioactive materials licensed by the NRC, which are packaged and labeled according to the DOT regulations,
are exempt from the labeling and posting requirements of 10 CFR 20.203 during shipment.
b. As 10 CFR 20.203(f) requires, containers with more than the quantities of radioactive materials specified in table
5-2 (10 CFR 20, app C) must be labeled with a durable, clearly visible radiation caution symbol (fig 5-4); the words
"Caution (or Danger) Radioactive Materials"; and sufficient information,
