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 ...

The DOE's Argonne National Laboratory has launched its Activated Materials Lab to study radiation effects in nuclear reactor ...

Scenes from the nuclear theater of a long cold war: In the 1940s and '50s, when Americans still trusted their doctors and their government, researchers subjected hundreds of ill-informed people to ...

Pacific Northwest National Laboratory chemist Isaac Arnquist examines the ‘coupons’ of ultra-low radiation copper cables specially created for sensitive physics detection experiments. Background ...

The Manhattan Project that built the atomic bomb wasn't without its own dangers. Experiments on a so-called "demon core" of plutonium caused the deaths of two Manhattan Project physicists. Both ...

Radiation is one of the key challenges faced by astronauts living and working beyond the protective shield of Earth's ...

Newly developed ultra-low radiation cables reduce background noise for neutrino and dark matter detectors. Imagine trying to tune a radio to a single station but instead encountering static noise and ...
