Bound-state beta decay is only measurable if the decaying ... cloud of 10 to 20 million years that is consistent with other radioactive species produced by the slow neutron capture process." ...

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.

A Wright Lab experiment capitalizes on simple physics to produce a groundbreaking technique to detect particle decay.

When beta radiation slows down it can produce ... However, if you don’t have one, you can look for yellowed glass. Radioactive decay could also cause hot spots on digital cameras.

The effects of the weak force were first discovered at the turn of the 20th century, in the place where it is most obviously at work: in radioactive beta decay. In the most common form of this ...

Astatine-211 (At-211) is one of a handful of promising alpha emitting radioisotopes for cancer therapy. Its short 7.2-hour ...

From mysterious dark matter to the radioactive decay of atomic nuclei, the past 12 months have reiterated just how strange particle physics can be. Everything in the universe is, quite literally ...

Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation. This physical phenomenon is called radioactivity and the radioactive ...

Like any radioactive material, there is a risk of developing ... In the case of DU, the only beta emitting decay products present are Th-234, Pa-234m andTh-231, all of which emit low intensity ...

The proton remains inside the nucleus, but the electron is ejected at high speed. This is called beta decay.. Beta decay causes the atomic number of the nucleus to increase by one (because there ...
