Depleted uranium would be my first choice for this; we had big bars of the stuff laying around the lab that we used for door stops. (The lab was a place that designed nuclear weapons.)
DU is harmless unless you eat or breathe it but alas it's now illegal to possess more than a minute quantity of it.
Tungsten is actually slightly denser and it has the advantage of being obtainable.
- KingMob 2y agoIsn't DU heavy metal-dangerous, but not radiation-dangerous?

- dreamcompiler 2y agoIt's both. DU is never completely "depleted" because radiation falloff is asymptotic. DU is primarily an alpha emitter and alpha particles cannot penetrate skin, but they can cause damage if you breathe, eat, or inject DU dust. That's why our use of big lumps of DU as door stops was considered "safe" (at that time several years ago) but in labs where people machined the stuff they were a lot more careful.
