Under which UN Class are radioactive materials categorized for transportation?

Radioactive materials are categorized under UN Class 7 for transportation purposes. This classification specifically addresses materials that emit radiation, which requires particular safety measures during transport to protect public health and the environment. UN Class 7 encompasses a variety of isotopes and products, including both low-level and high-level radioactive waste, as well as other radioactive substances used in medical, industrial, and research applications.

The classification is crucial for ensuring that proper protocols are followed, including packaging, labeling, and documentation, which help to mitigate the risks associated with the transportation of these materials. The international regulations governing the transport of hazardous materials, known as the Dangerous Goods Regulations, specifically outline the requirements for Class 7 to ensure safe handling and compliance.

In contrast, other UN classes, such as UN Class 5 (oxidizing substances), UN Class 6 (toxic and infectious substances), and UN Class 8 (corrosive substances), deal with different types of hazards and do not encompass radioactive materials. Understanding these classifications is essential for radiation safety officers to ensure compliance with transportation regulations and to maintain safety standards when dealing with radioactive substances.
