metals are NON-TOXIC until you fucking eat this or some shit.
you are not gonna get hurt from a NON-OXIDIZED "radio-active" material
the radioactivity of metals occurs mostly after it is exposed to a centrifuge and shit like that
don't eat lead? don't eat yterribium.
dont eat mercury either
dont put mercury on yterribium or you might be in trouble?
