Mixed waste is waste that contains both radioactive components and other hazardous components.
Transuranic, or TRU, waste generally consists of protective clothing, tools, glassware, equipment, soils, and sludge contaminated with manmade radioisotopes heavier than uranium. These elements include plutonium, neptunium, americium, curium, and californium. Types of Transuranic Waste Transuranic waste is itself divided into two categories, based on its level of radioactivity. It is packaged in 55-gallon metal drums or in metal boxes and can be handled under controlled conditions without any shielding beyond the container itself. The maximum radiation dose at the surface of a contact-handled transuranic waste container is 200 millirems per hour.
