Ulah lan Wuku
- 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.
- nggunakake paling umum saka logam Sesium yaiku adi ngebur. Sampeyan uga dipigunakaké ing Manufaktur kaca optik.
- Ing tabung vakum lan peralatan monitor radiation logam iki digunakake minangka katalis tukang promosi.
