I'm curious why this can't be purified... What is the PPM of radioactive material to normal lead/steel? For instance could you take a massive chunk of normal irradiated steel and divide it into small chunks, measure each chunk and keep the best X%, rinse repeat?

These arent physically visible or even microscopically isolated chunks, these are radioactive atoms diffused through the bulk metal. And as there are ~10^24 atoms in 100 grams of iron... go figure

The cobalt is diffused pretty uniformly in the volume: it's blown in and alloys well. Making steel without any source of contamination would be possible but very expensive.
