transuranic
Past atomic ninety-two
Transuranic describes chemical elements heavier than uranium—those with atomic numbers greater than 92.
All transuranic elements are radioactive and unstable, most created artificially in nuclear reactors or particle accelerators: plutonium, americium, curium.
Transuranic waste from nuclear facilities requires special handling.
The term appears primarily in chemistry and nuclear science contexts.
