What class of hazardous materials includes radioactive substances?

The class of hazardous materials that includes radioactive substances is Class 7. This classification is specifically designated for materials that emit radiation, which encompasses a wide range of radioactive isotopes and compounds. Radioactive materials are regulated due to their potential to cause harm to health and the environment, and proper handling, storage, and transportation protocols are essential to minimize risks associated with exposure.

Class 1 pertains to explosives, Class 3 relates to flammable liquids, and Class 5 includes oxidizers and organic peroxides. Each of these classes is distinct, focusing on different types of hazards that do not involve radiation, thus underscoring the unique nature of radioactive materials and their classification as Class 7. Understanding these classifications is crucial for ensuring safe handling and compliance with regulatory requirements in the transport of hazardous goods.
