2.As a proof of principle, Cederwall and colleagues focused on detection of californium-252, a readily available radioisotope widely used as a proxy for weapons-grade plutonium.
3.But the chase for 120 is on hold until researchers obtain the amount of californium—a rare element produced in high-flux nuclear reactors—needed for 120’s target.
4.Worse, the sample that the Berkeley researchers received was heavily contaminated with einsteinium’s periodic table neighbor, californium.
5.From copper to californium, we discover how the sober face of the periodic table hides dramatic backstories.
6.In March 2018, investigators seized what they thought was 1.4 kilograms of californium, but that find actually turned out to be a natural substance with no radioactivity.
7.After californium, it is the second element named for one of the 50 states.
8.Over the course of 30 years, his inventions contributed to the discovery of americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium and seaborgium.
9.With 99 protons and 99 electrons, it sits in obscurity near the bottom of the periodic table of chemical elements, between californium and fermium.
10.It is evident in entries like francium, germanium, scandium, polonium, europium, californium, berkelium and americium.
11.The 18.1 grams of californium were seized in the northern Bolu province of the country, law enforcement officials said Saturday, according to the Daily Sabah.
12.Scientists at the University of California at Berkeley in 1950 announced they had created a new radioactive element, "californium."
13.Research onto a little-known element called californium may open up completely new opportunities to store radioactive waste and recycle radioactive fuel.
14.In 1950, scientists at the University of California at Berkeley announced they had created a new radioactive element, “californium.”
15.The team behind the study, published in the current edition of Nature Chemistry, found that californium had an extraordinary capability to bond with and separate other materials.
16.Only the U.S. and Russia have created californium.
17.The five milligrams of californium used in Albrecht-Schmitt’s research cost a whooping $1.4 million to obtain, and required years of work with the U.S.
