Narrator: It is named after Poland, Marie Curie's homeland.

Narrator: "Polonium-210" describes its best-known isotope, a strong alpha emitter.

Narrator: It differs from radium because polonium is far more radioactive by weight.

Narrator: "Polonium poisoning" is a second pattern, linked to a notorious 2006 case.

Narrator: Nuclear physics, static removal and space power sources rely on polonium.
