Definition of polonium in English:

polonium

noun pəˈləʊnɪəmpəˈloʊniəm

mass noun

The chemical element of atomic number 84, a radioactive metal occurring in nature only as a product of radioactive decay of uranium.
（化学元素）钋（符号： Po ）
Example sentencesExamples
- Gentry had discovered that granites contain microscopic coloration halos produced by the radioactive decay of primordial polonium.
- This generator is a small pellet of polonium and beryllium, separated by foil within the fissionable fuel core.
- Radon can enter the body through the lungs, where it undergoes alpha decay to form polonium, a radioactive solid that remains in the lungs and continues to emit cancer-causing radiation.
- In the process, she discovered two new elements that are millions and billions of times more radioactive than uranium: radium and polonium.
- The uranium eventually decays to radium and, eventually to polonium-210, a substance that, when inhaled, can endanger tissue health and damage the immune system.

Origin

Late 19th century: modern Latin, from medieval Latin Polonia 'Poland' (the native country of Marie Curie, the element's co-discoverer).

Rhymes

ammonium, euphonium, harmonium, pandemonium, pelargonium, plutonium, zirconium
