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 is ...

When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into polonium.

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 weak nuclear force drives the process of nuclear beta decay. In beta decay, a proton or neutron in a nucleus emits a beta particle (an electron or its anti-particle, a positron) and a neutrino.

Wilhelm Röntgen discovered X-rays while experimenting with cathode rays and crystals, leading to the realization that ...

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 ...

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.

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 ...

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 ...

Like any radioactive material, there is a risk of developing cancer from exposure to ... products of uranium that are normally found in equilibrium with the uranium isotopes. In the case of DU, the ...
