Radioactive Waste Management Concepts

Radioactive waste, a byproduct of medical, industrial, and nuclear activities, requires careful management to protect people and the environment. It is characterized by its physical, chemical, and radioactive properties, then processed and classified for safe storage and disposal. Waste is categorized into very low-level, low-level, intermediate-level, and high-level, each requiring different management strategies. High-level waste, the most hazardous, is stored in purpose-built facilities and planned for disposal in deep underground sites. The IAEA supports countries in managing radioactive waste safely.
