The element radium can be found in extremely tiny amounts in the Earth’s crust and oceans, and in its pure form it is a soft silvery metal. To an untrained eye, a small piece of radium may look like a ...

Researchers grew crystals containing actinium and illuminated them with X-rays to learn how the radioactive metal binds with other elements. That information could help design better cancer treatments ...

Researchers at University of Tsukuba have developed a cellulose-based composite sheet that integrates paper pulp with starch, ...

A novel apparatus at the U.S. Department of Energy's (DOE) Argonne National Laboratory has made extremely precise ...

In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

Nearly 80 years after scientists at Oak Ridge National Laboratory discovered an extremely rare radioactive element called promethium, a team at the lab published a landmark study on the subject that ...

Scientists have revealed key properties of radioactive promethium, a rare earth element with poorly understood applications, using a groundbreaking new method. When you purchase through links on our ...
