- 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.
- Kang digunakake kanggo riset waé. jumlah cilik saka logam digunakake ing batre atom.
- bosok radioaktif sawijining digunakake kanggo Phosphor kanggo menehi mati lampu. Lampu cemlorot diowahi dadi listrik.
