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 ...

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, ...

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 ...

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 ...

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

The study published in JAVMA highlights a critical lack of veterinary-specific data on PET/CT radiation exposure.

Yes, the items--such as smoke alarms, 1950s-era pottery and uranium ore rocks--are commercially available to anyone, but that didn't make the discovery that they were being disassembled to accumulate ...
