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 ...

What is dark matter? What are neutrinos all about? How do stars work and what was actually going on in the universe in the first minutes after the Big Bang? To answer these questions, you need very ...

Researchers at the National Institute of Standards and Technology (NIST) have unveiled a groundbreaking method for rapidly detecting and measuring radioactivity in minuscule samples. The technique, ...

An international team of physicists has successfully measured the size of a certain type of neutrino to a certain degree. In their paper published in the journal Nature, the group describes ...

Natural radiation from space can interfere with measuring radioactivity in scientific samples. The IAEA built an underground lab to minimize this interference and allow precise measurements. In Monaco ...

Physicists have measured a nuclear reaction that can occur in neutron star collisions, providing direct experimental data for a process that had previously only been theorised. The study provides new ...

A number of instruments are heavily dependent on the performance of the detector at their core, including pyranometers ...

IWAKI, Japan, March 9 (Thomson Reuters Foundation) - At a laboratory an hour's drive from Japan's Fukushima nuclear plant, a woman with a white mask over her mouth presses bright red strawberries into ...
