What is the half-life of nuclear waste?

The half-life of nuclear waste varies significantly depending on the specific isotopes involved. Some isotopes, like iodine-131, have a short half-life of about 8 days, while others, such as plutonium-239, have a half-life of 24,100 years. This wide range means that some nuclear waste can remain hazardous for thousands to millions of years, necessitating careful long-term management and storage solutions.
