Scientists have caught a handful of ghost particles escaping from deep inside Earth, leaving experts to wonder: What if our planet’s interior isn’t as evenly mixed as we thought? The particles, ...

Four decades after the Chernobyl disaster, scientists have found that radioactive particles released from the reactor remain ...

Four decades after the 1986 nuclear disaster, researchers at Leibniz University Hannover and the Helmholtz-Zentrum ...

Not all of the material around us is stable. Some materials may undergo radioactive decay to form more stable isotopes. Scientists have now observed a new decay mode for the first time. In this decay, ...

Observing the recoil caused by a single radioactive decay could help physicists spot exotic particles and possibly even dark matter. Radioactive decay is ubiquitous. It occurs everywhere on Earth and ...

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 ...

The detector array consists of plastic scintillator detectors, quadrant silicon detectors (QSD), double-sided silicon detectors (DSSD) and high-purity germanium (HPGe) detectors. Exotic nuclei near ...

Four decades after the world's worst nuclear disaster, scientists have uncovered a chilling reminder that Chernobyl's ...

Physicists proposed a way to focus ghostly neutrinos into a laser-like beam, but new MIT calculations show that violent ...

Students learn how radioactive decay is measured through activity and half‑life, using standard scientific units. They practise finding half‑life from radioactive decay graphs and calculating ...

For the first time, scientists observe a new and rare decay mode where oxygen-13 breaks into three helium nuclei and a proton following beta decay. Scientists have previously observed interesting ...

Scientists have previously observed interesting modes of radioactive decay following the process called beta-plus decay. This is where a proton turns into a neutron and emits some of the produced ...
