Ulah lan Wuku
- Californium logam emitter neutron kuwat banget. Kang digunakake minangka detector logam.
- Uga digunakake minangka pengenal kanggo mriksa banyu lan lapisan lenga ing sumur lenga.
- 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.
