Ulah lan Wuku

metal Actinium wis sumber sinar alfa nanging ora dienggo njaba riset waé.

Iki digunakake kanggo harden baja lan mrodhuksi stainless steel lan macem-macem wesi liyane.
Iki uga digunakake kanggo menehi finish sing tepat kanggo mirrors polesan. Piring kromium digunakake ing perlengkapan jedhing.
