It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume. Carbon in the form of diamond can be more expensive than rhodium. Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars.

15. Iridium. Cost: $162.26 per gram. Iridium is a hard, silvery metal that is one of the rarest in the world. It's also extremely corrosion resistant. Iridium is mainly used as a hardening agent ...
Iridium in bulk metallic form is not biologically important or hazardous to health due to its lack of reactivity with tissues; there are only about 20 parts per trillion of iridium in human tissue. [22] Like most metals, finely divided iridium powder can be hazardous to handle, as it is an irritant and may ignite in air. [66]
Conversions between units in the metric system are defined by their prefixes (for example, 1 kilogram = 1000 grams, 1 milligram = 0.001 grams) and are thus not listed in this article. Exceptions are made if the unit is commonly known by another name (for example, 1 micron = 10 −6 metre).
At 3% fission products by weight, one ton of used fuel will contain about 400 grams of rhodium. The longest lived radioisotope of rhodium is 102m Rh with a half-life of 2.9 years, while the ground state (102 Rh) has a half-life of 207 days. [1] Each kilogram of fission rhodium will contain 6.62 ng of 102 Rh and 3.68 ng of 102m Rh.
