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 ...

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

Science, founded by Thomas A. Edison in 1880 and published by AAAS, today ranks as the world's largest circulation general science journal. Published 51 times a year, Science is renowned for its ...

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 ...

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 ...
