Most costly radioactive material valued at 25.6 million
The new development in the production of Californium-252 aims to reduce the separation process duration, which previously took two weeks. Researchers at Oak Ridge National Laboratory have successfully improved the method by using a neutral solvent, cutting the time by about a week and lowering costs. This advancement is crucial to meet the increasing demand for this rare isotope in nuclear and industrial applications, especially as the United States expands its nuclear energy sector and small reactor projects. The laboratory produces less than one gram of Californium-252 annually, making it one of the most expensive radioactive materials. It is characterized by its ability to emit millions of neutrons from its self-splitting nucleus, rendering it vital for nuclear reactors, pollution detection, oil well exploration, and national security.
