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 ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. If dark matter particles decay, then scientists could hunt for signs of this process, including X-ray or gamma-ray radiation or ...

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 ...

Students learn the key properties of alpha particles, beta particles, and gamma rays, comparing their ionising abilities and penetrating powers. They practise constructing balanced nuclear decay ...

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, ...

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 ...
