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 ...

Tiny worms that live in the highly radioactive Chernobyl Exclusion Zone were found to be immune to radiation — which scientists hope could provide clues about why some humans develop cancer, while ...

Forty years after Chernobyl changed history forever, discover 17 fascinating and heartbreaking facts about the world’s worst ...

Wastewater release from the Fukushima Daiichi nuclear plant in Japan is expected to have negligible effects on people and the ocean, Jim Smith and colleagues report in a Perspective. The planned ...

These beams are aimed at the tumour from many different directions to maximise the dose on the tumour but to minimise the dose on the surrounding soft tissue. This technique can damage healthy tissue, ...

At the centre of all atoms, lies the nucleus. The nuclei of most atoms are stable. That means they do not decay over time. The nucleus of an unstable atom is considered radioactive since it changes ...

On a Wednesday morning in late January 1896 at a small light bulb factory in Chicago, a middle-aged woman named Rose Lee found herself at the heart of a groundbreaking medical endeavor. With an X-ray ...

The Trump administration's skepticism about regulations of all types is giving visibility to a fringe theory, which posits that low doses of ionizing radiation have health benefits.

Cause and Effect: Understanding the causes of radioactive decay and its effects on materials and organisms. (Example: Exploring how distance and shielding materials affect exposure to radiation.) ...
