A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive ...

The rise of a new generation of radiotherapies means we will soon need much greater quantities of radioactive atoms. That's ...

Writing in Nature, Zhang et al. 1 provide a rare atomic-level glimpse of a notoriously dangerous radioactive element, americium (Am), in its highest oxidation state. The authors used a water-soluble ...

“Probably the most useful tool for research since the discovery of the microscope” was described in detail last week by Dr. Joseph G. Hamilton of the University of California. The tool he referred to ...

Chemists could more readily study the properties of rare radioactive materials by bonding them to bulky companions 1. Some of the radioactive elements known as actinides are so scarce that just a few ...

A concentration of one part per billion is like a pinch of salt in 10 tons of potato chips—and scientists can now find radioactive particles at concentrations millions of times smaller. In the Journal ...
