radioactive californium

Californium is named after the US state of
California. This soft, silvery metal does not exist
in nature and is made by smashing berkelium atoms
with neutrons in a particle accelerator (a machine in
which atoms are smashed together). This radioactive
Water detector element is used in the treatment of cancer.

year.

Einsteinium was discovered in the chemicals
left over after the first hydrogen bomb test
in 1952. The huge explosion fused smaller
atoms together to make larger ones, including
einsteinium. This element was named after the
great German-born scientist Albert Einstein, and
was found to be a silvery, radioactive metal that
glows blue in the dark. It is only used for making
Albert Einstein in his study heavier elements, such as mendelevium. 125
