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.

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]
Since a typical used nuclear fuel contains about 3% fission products, one ton of used fuel will contain about 1.9 kg of ruthenium. The 103 Ru and 106 Ru will render the fission ruthenium very radioactive. If the fission occurs in an instant then the ruthenium thus formed will have an activity due to 103 Ru of 109 TBq g −1 and 106 Ru of 1.52 ...
The international prototype of the kilogram (IPK) is an artifact standard of platinum–iridium alloy that was defined as having a mass of exactly one kilogram. Platinum–iridium alloys are alloys of the platinum group precious metals platinum and iridium. Typical alloy proportions are 90:10 or 70:30 (Pt:Ir).
Iridium-192 is a very strong gamma ray emitter, with a gamma dose-constant of approximately 1.54 μSv·h −1 ·MBq −1 at 30 cm, and a specific activity of 341 TBq·g −1 (9.22 kCi·g −1). [ 14 ] [ 15 ] There are seven principal energy packets produced during its disintegration process ranging from just over 0.2 to about 0.6 MeV .
India is the third largest oil consumer after USA and China and India is the second biggest importer of oil. India uses 5.5 million barrels of oil per day. [ 14 ] India buys crude oil from Saudi Arabia, Iraq, Iran, Kuwait, Kazakhstan, Russia, [ 15 ] [ 16 ] [ 17 ] and UAE with significantly reduced amount from Nigeria in 2021.
