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

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 ...

Discover the fascinating process of radioactive decay, where unstable atoms transform, releasing energy in the form of alpha, beta, and gamma emissions.

Scientists have detected elevated levels of iodine-129, a nuclear activity tracer, in the West Philippine Sea.

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 ...

Radioactive potassium, common enough on Earth to make potassium-rich bananas one of the “hottest” foods around, appears also to be a substantial source of heat in the Earth’s core, according to recent ...
