Can osmium replace calcium or be placed in with it to make an organic human exoskeleton

I am trying to design my main character in my post-apocalyptic series to have a very dense, organic, durable skeleton. The skeleton should also be able to handle gun fire, a sledge hammer impact, as well as gamma rays (and other ionizing radiation).

My idea was to have an osmium, iron, and carbon nanotubes structure organically woven to get him to make a dense, durable, armor that can handle a lot of kinetic energy, like machine gun fire. The character already has very strong muscles and padding around the organs. Does this seem realistic, or is there a better way to go about this?

Where she gets the osmium isn't important; just applying it to her biochemistry is.
