3.1 Ulah lan Wuku

Punika logam Highly radioaktif; lan arang-arang Radium-223 digunakake kanggo nambani kanker prostat.
Kang digunakake ing cat cetha.

Wis Efesus banget winates minangka logam beracun lan bisa nimbulaké cacat lair, kanker, etc.
Meh 80% saka logam kadmium digunakake ing Nikel Baterei kadmium lan saiki lagi njupuk diganti karo isotop nikel.
