What is the densest non-radioactive metal?

I'm looking for the heaviest non-radioactive metal for the size (the densest). I’m guessing lead or gold. What else is out there?

    Iridium, a metal of the platinum family, is white, similar to platinum, The specific gravity of iridium is only very slightly lower than osmium, which is generally credited as the heaviest known element. Calculations of the densities of iridium and osmium from the space lattices give values of 22.65 and 22.61 g/cm^3, respectively. These values may be more reliable than actual physical measurements. At present, therefore, we know that either iridium or osmium is the densest known element, but the data do not yet allow selection between the two. Although its principal use is as a hardening agent for platinum, iridium is also used to make crucibles and devices requiring high temperatures. It is also used for electrical contacts.

    The element forms an alloy with osmium which is used for tipping pens and compass bearings.

    Osmium. At 22.6 grams per cubic centimeter.

    lead has a very high density and is more stable

      What part of "non-radioactive" confused you? (he says 8 years later).
      And don't anyone try to be a smart *** and say it's not radioactive because it's depleted. Depleted uranium is still very radioactive.
