RADIOACTIVE DECAY: understand radioactive decay. describe alpha, beta and gamma radiation? Atomic Theory and Radioactive Decay Natural background radiation exists all around us. This radiation consists of high energy particles or waves being emitted from a variety of materials. Radioa...
On Earth many nuclei are unstable, and they can reach a more stable configuration through radioactive decays. These nuclei are indicated as radioactive due to their emission of nuclear radiations. Depending on the emitted particles they are classified as alpha, beta, and gamma decays. Radio...
Alpha decay involves the release of a positively charged particle and reduces the atomic number of the atom by two protons. Beta decay involves the breakdown of a neutron into a proton and the release of a high energy electron. Gamma decay usually accompanies other types of decay and releases...
In alpha decay, the nucleus splits and releases and alpha particle (helium nucleus), lowering the atomic number by two and the atomic mass by four. In beta decay, a neutron transforms into an proton and releases energy equivalent to an electron in the process. Gamma decay is radiation ...
Radioactive decay [edit] Types of decay Alpha particles may be completely stopped by a sheet of paper, beta particles by aluminum shielding. Gamma rays can only be reduced by much more substantial barriers, such as a very thick layer of lead.As for types of radioactive radiation, it was ...
Among radioactive materials which occur naturally here on Earth, two kinds of radioactive decay are common: alpha (α) and beta (β). They get their names from the most obvious particles emitted, an alpha particle (which is the nucleus of the stable isotope of helium called helium-4) or...
Radioactive decay, also known as nuclear decay or radioactivity, is a random process by which an unstable atomic nucleus loses its energy by emission of radiation or particle. A material containing unstable nuclei is considered radioactive.

* alpha radiation is the least penetrating (of alpha, beta, and gamma); typically it goes no more than a few cm in air * like all kinds of radioactive decay, alpha decay occurs because the final state of the nucleus (the one decaying) has a lower energy than the initial one (the ...
