Difference between high level and low level radioactive waste?

High-level radioactive waste is highly radioactive and generates significant heat, typically resulting from nuclear reactor operations and spent nuclear fuel. It requires extensive shielding and long-term management, often stored in deep geological repositories. In contrast, low-level radioactive waste contains lower levels of radioactivity and can include items like contaminated clothing or tools. It generally requires less stringent handling and can often be disposed of in near-surface facilities.
