What are the dangers of iridium?

Exposure to Ir-192 can increase the risk for cancer because of its high-energy gamma radiation. External exposure to Ir-192 can cause burns, acute radiation sickness, and even death. Internal exposure could occur only if a person were to swallow one of the Ir-192 seeds or pellets.

Is iridium harder than gold?

Iridium: Iridium doesn't share much in common with gold, but all the metals on this list are noble metals – meaning they resist corrosion. Iridium is brittle and shares none of gold's softness and malleability.

The International Atomic Energy Agency defines iridium-192 as a category-2 radioactive substance. This means the substance can permanently injure a person who handles the radioactive material for minutes to hours, and it can kill people in close proximity within hours to days, according to the agency.

Why is iridium rare on Earth?

Iridium and osmium, among others, are almost absent from the earth's crust (on average, for iridium, 0.1 nanograms per gram of rock) because they essentially accompanied iron in the Earth's core during the differentiation of the Earth more than 4.4 billion years ago.
