Info is meant for Radioactive waste
High-Level Waste
[edit]High-level radioactive waste consists of spent fuel rods that are hot and very radioactive, usually consisting of elements such as cesium-137 and strontium-90.[1] The half-lives of radioactive wastes vary quite extremely. The half-lives of elements such as cesium-137 and strontium-90 is usually around 30 years, while elements such as plutonium may span as long as 24,000 years.[1]
Mill Tailings
[edit]Mill tailings are not very radioactive, but have long half-lives. They are produced by milling specified ores in order to extract materials such as uranium and thorium. Tailings often contain radium, thorium and trace amounts of uranium.[1]
