What are 3 uses for iridium?

Iridium’s primary use is a hardening agent for platinum. Other uses for iridium include fountain-pen nibs (alloyed with osmium), compass bearings, high-temperature crucibles and heavy-duty electrical contacts.

What happens if you touch iridium?

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.

What happens if you eat iridium?

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. Internal exposure from Ir-192 could cause burns in the stomach and intestines if the high-energy industrial pellets are swallowed.
