Alpha decay or α-decay is a type of radioactive decay in which an atomic nucleus
emits an alpha particle (helium nucleus) and thereby transforms or 'decays' ...
Watch alpha particles escape from a polonium nucleus, causing radioactive
alpha decay. See how random decay times relate to the half life.
... kind of radiation. The most common types of radiation are called alpha, beta,
and gamma radiation, but there are several other varieties of radioactive decay.
The incredible range of alpha decay half-lives can be modeled with quantum
mechanical tunneling. The illustration represents the barrier faced by an alpha ...

decay is a type of radioactive (nuclear) decay. Here, I explain what ...
Alpha decay is a radioactive process in which a particle with two neutrons and
two protons is ejected from the nucleus of a radioactive atom. The particle is ...
Alpha Decay. In 1899, Ernest Rutherford wrote the following words: "These
experiments show that the uranium radiation is complex and that there are
present at ...

There are three main types of radioactive decay: alpha, beta, and gamma. Let's
pause here a minute to define "decay." When an element decays the parent ...

Alpha decay, type of radioactive disintegration in which some unstable atomic
nuclei dissipate excess energy by spontaneously ejecting an alpha particle.
