Nuclear waste refers to the byproducts generated from nuclear reactors, medical applications, and research activities. This waste can be highly radioactive and poses significant environmental and health risks if not managed properly. Safe disposal methods are crucial to prevent contamination and protect future generations. There are different types of nuclear waste, including low-level waste, intermediate-level waste, and high-level waste. Each type requires specific handling and disposal techniques. Long-term storage solutions, such as deep geological repositories, are being developed to ensure that nuclear waste is isolated from the environment for thousands of years.
