The Lawrence Livermore National Laboratory study shows that the formation of radioactive fallout is more complex than some ...

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 ...

In this collection of lab-based activities, students will learn about the concepts of radiation and half-life in order to gain an understanding of the use of radiocarbon dating as a method of absolute ...

Scientists at Lawrence Livermore National Laboratory recreated part of the intense chaos inside a nuclear fireball to better ...

Hair oil spiked with radioactive elements seems like an obviously bad idea to us now. But in the decades right after scientists such as Marie Skłodowska-Curie and Pierre Curie observed and ...

Carolyn Pearce is busy digging up, cutting up and even x-raying ancient glass across the globe for study. Why? She’s trying to figure out the properties of the strongest glass on earth today, ones ...

The writer of a letter to the editor in the Nov. 6/13, 2023, edition, titled “Nuclear Waste,” has some serious misconceptions about disposal of such waste (page 3). If these were corrected, he would ...

In this lesson, students will investigate the nature of radioactivity and the effect of both distance and shielding materials on different radioactive sources using a Geiger-Muller tube with a counter ...
