Which class uses placards to denote radioactive materials?

Explanation:
Placards are used to communicate the specific hazard of a shipment so anyone handling it knows what dangers to expect and how to respond. The placard for radioactive materials is the one that features the radiation trefoil symbol. That symbol, along with the indication of the radioactive category, is what signals that the material falls into the class dedicated to radioactive substances. Other hazards have different symbols and identities (like corrosives, oxidizers, or miscellaneous dangerous goods), so the radiation symbol clearly points to the radioactive category.
