What is Polonium-204?

Polonium is a chemical element and highly radioactive metal, harboring a chemical structure similar to selenium and tellurium.

Discovered by Marie and Pierre Curie, after being extracted from the uranium ore pitchblende and labeled as highly radioactive, the pair named it Polonium after their native Poland and deemed it extremely dangerous to humans.

In the real world, it is used to remove static electricity from various types of machinery, lift dust from photographic film as an antistatic remover, and act as a lightweight heat source for thermoelectric power in space probes.

Any form of radiation exposure carries the risk of death or cancer and it has been suggested that chelation agents, including British Anti-Lewisite, can be used to decontaminate poisoned humans.
