A radioactive form of palladium (a metallic element that resembles platinum). When used to treat prostate cancer, radioactive seeds (small pellets that contain radioactive palladium) are placed in the prostate.
palladium (Pd), chemical element, the least dense and lowest-melting of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, used especially as a catalyst (a substance that speeds up chemical reactions without changing their products) and in alloys.
About a dozen radioactive isotopes of palladium are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation. Radioactive isotopes are produced when very small particles are fired at atoms. These particles stick in the atoms and make them radioactive.
Palladium is a chemical element with symbol Pd and atomic number 46. Classified as a transition metal, Palladium is a solid at room temperature.
Palladium is regarded as of low toxicity, being poorly adsorbed by the body when ingested. It may cause skin, eye or respiratory tract irritation, may cause skin sensitisation. Liquid may cause burns to skin and eyes.

Palladium-catalysed reactions are so valuable that, in 2010, their discoverers shared a Nobel prize. But despite its versatility, chemists are trying to move away from palladium. The metal is more expensive than gold, and molecules that contain palladium can also be extremely toxic to humans and wildlife.
It is now cherished for its lustrous silvery-white finish and because of its similar properties to platinum. Palladium is resistant to corrosion and will not tarnish in air.
Palladium's most incredible ability is that it can absorb up to 900 times its volume of hydrogen, according to the Thomas Jefferson National Accelerator Facility. Because of this ability, palladium is used to store and filter hydrogen.
Palladium isn't magnetic. If the piece you have is a forgery, it may contain iron. This is because iron is an inexpensive metal that's relatively easy to mold and shape. If your piece contains any amount of iron, it will react to a magnet.
Palladium has the lowest melting point (2830.82 °F) and is the least dense of the PGMs. Deposits of palladium are rare, but are found in South Africa, Canada, and Russia. Much of the world's demand for palladium is met by recycling catalytic converters.
Palladium is 30 times rarer than gold and nearly 15 times rare than platinum. That makes it a unique option for wedding bands and engagement rings. That means it'll be challenging to find a variety of styles and choices at the jewelers because of a low supply.
The carcinogenic potential of the palladium ion is still unclear, although there is some evidence that it is capable of acting as a mutagen. However, there are no well documented cases of adverse biological reactions to palladium in the metallic state.
Palladium is a chemical element that is similar to platinum. A rare, silver-white precious metal, palladium has been commonly used for fine jewelry since the 1930s.
Palladium is one of the rarest metals on earth and even more scarce than platinum – 15 times more rare to be precise. If all the platinum in the world fits in your house, then every ounce of palladium can easily squeeze inside your living room.
Gold and palladium are totally soluble in one another. The primary use of gold / palladium alloys is in jewellery. The alloy is more commonly known as white gold and is an alternative to platinum. Gold / nickel alloys are also used as white gold.
What Is Palladium Used for? Palladium is used in catalytic converters for automobiles, in fuel cells to generate power, in jewelry, dental fillings, and electronic components. Catalytic converters convert the toxic gases from automobiles into less harmful substances.
Most palladium is used in catalytic converters for cars. It is also used in jewellery and some dental fillings and crowns. White gold is an alloy of gold that has been decolourised by alloying with another metal, sometimes palladium.
Some people don't like the 'light' feel of palladium compared with platinum. Because it's a newcomer to the jewellery market, it's too soon to say whether palladium will keep its value so it's probably not the best metal to choose if you're looking to make a long-term investment.
So, is it a good time to buy palladium? We believe so. The market factors indicate that 2022 would be a great time for precious metal investors to get in on the palladium market. If you are new to coin and precious metal investments, you don't have to worry about entering the market blindly.
Like most other precious metals Palladium does scratch. Despite being harder than Platinum, it will nevertheless pick up scratches.
Palladium does not tarnish and will keep it's white color indefinitely. It is much lighter than platinum, similar in weight to 14 karat gold. I find that at current precious metal markets the same design cost a bit less in palladium than it cost in 14k palladium white gold.
Palladium is used in emission-reducing catalytic converters in gasoline engines, but the metal's price surge has driven automakers to replace it with platinum.
Iron-aluminium compound could replace palladium catalyst, reducing the cost of plastic production. (Phys.org) -- Chemists don't like precious metals – at least not when they need the expensive materials as catalysts to accelerate reactions or guide them in a particular direction.
This case shows that an isolated sensitization to palladium can occur and that respiratory exposure to palladium is a novel cause of metal-induced occupational asthma.
