About half of the Cobalt that is mined on Earth can be found in rechargeable batteries. The rechargable batteries in one's cell phone, for example, contains a poisitive cathode structure that cobalt plays a large role in. Cobalt allows rechargable batteries to function, leading to a more sustainable future.

Since October 27, 1951, the Eldorado Cobalt-60 radiation technology has helped 35 million patients in their battle against cancer. This unit saves money, is easy to use, and is so reliable that it is utilized in 70% of radiation treatments. Having the ability to target deep-seated tumors without harming the skin is what sets Cobalt radiation apart from other types of radiation.
