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 demonstrated a new and faster method for detecting and measuring the radioactivity of minuscule amounts of radioactive ...

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 ...

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, ...

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 ...

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 ...

Radiation safety experts from the Tokyo Electric Power Company (TEPCO) in Japan visited two IAEA laboratories in Vienna and Seibersdorf, Austria and learned about the IAEA’s upgraded techniques for ...
