Malunga i-Californium
Californium-252 spontaneously fissions, emitting useful neutrons. Only about 500 micrograms are produced yeminyaka e-US. It is one of the most expensive substances on Earth.
Izisebenziso
Ukuqashwa kwe-nuclear reactor, ama-moisture gauges, ukuqoqwa kwe-oil well, kanye nokwelashwa kwe-cancer.
Iqiniso elijabulisayo
Californium-252 izindleko cishe $ 27 million ngegramu, nakuba kuphela microgram inani ngokuvamile kudingeka.
