The origin of xenon in the containment of Fukushima Daiichi 2 is currently considered to be spontaneous fission, a process of radioactive decay not involving any chain reaction. The origin of xenon in ...

A radioactive decay chain and the spectrum obtained by the INTEGRAL observatory. Note the scale of the vertical axis -- about one gamma quantum an hour per 1cm2! Disclaimer: AAAS and EurekAlert! are ...

Predicted α-decay chain of new element 119 isotopes (²⁹³,²⁹⁴119), highlighting several as-yet-undiscovered nuclei. The proposed use of ⁴⁰Ar beams offers a promising approach for synthesizing key ...

Radioactive decay is the strange and almost mystical ability for one element to naturally and spontaneously transmute into another. In the process, those elements tend to emit deadly forms of ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

For the first time, a research team from the University of Cologne has observed the electron capture decay of technetium-98, an isotope of the chemical element technetium (Tc). Electron capture decay ...
