The radiation emitted from unstable nuclei is ... 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 ...

JON CHASE:'The decay of these unstable elements is known as ionising radiation. 'There are three main types - alpha, beta or gamma. JON CHASE:'Gamma radiation is pure energy, 'but alpha and beta ...

Nuclear energy is often promoted as a cleaner alternative to fossil fuels because it doesn’t emit carbon dioxide. However, ...

In 1930, Wolfgang Pauli (the father of the Pauli Exclusion Principle) proposed the existence of the neutrino to explain the conservation of energy in beta radioactive decay. Beta radioactive decay ...

The atom can be characterized by the number of protons in the nucleus. Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation ...

This is not the case however with natural uranium, where people are also exposed to the more penetrating beta and gamma radiation emitted by the decay products of uranium that are normally found in ...

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." ...

Atoms which have unstable nuclei are radioactive and are called radioisotopes or radionuclides. The change that an unstable nucleus undergoes is called disintegration or decay. When unstable nuclei ...

Ionising radiations (IR) occurs as either electromagnetic rays (such as X-rays and gamma rays) or particles (such as alpha and beta particles). IR occurs naturally (e.g. from the radioactive decay of ...

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 ...
