Among ionising radiation, alpha and beta particles are charged particles that have widely attracted research attention because of their use in a number of applications including smoke detectors, ...

Radioactivity is the act of emitting radiation spontaneously and is done by an atomic nucleus (unstable) to attain a more stable configuration by giving up some energy. Radioactivity is a physical, ...

Rainwater containing elevated levels of radioactivity has been detected in the U.S., an effect of the ongoing nuclear crisis in Japan. Stephen Sugarman of the Oak Ridge Institute for Science and ...

Each of us is bathed in an invisible ocean of radioactive particles and energies — alpha and beta particles, gamma rays, X-rays, neutrinos, muons, etc. In the vast majority of cases, this radiation ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma ...

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 ...

The state Department of Environmental Protection released what it says is the most thorough study conducted of radioactive materials associated with oil and gas extraction on Thursday. In January 2013 ...

Alpha recoil: Conceptual drawing of the experiment, which detects the nuclear decay of individual helium nuclei by embedding radioactive atoms in a micron-sized object and measuring the object’s ...

Radiation tends to strike fear in the hearts of the general populace, particularly the ionizing variety produced by X-rays and radioactive elements. But most have no idea what actual radiation looks ...
