And if at times these things bent the welded iron of his soul , much more did his far-away domestic memories of his young Cape wife and child , tend to bend him still more from the original ruggedness of his nature , and open him still further to those latent influences which , in some honest-hearted men , restrain the gush of dare-devil daring , so ...
Radioactive decay (also known as nuclear decay or radioactivity) is the process by which the nucleus of an unstable atom loses energy by emitting radiation, including alpha particles, beta particles, gamma rays, and conversion electrons. A material that spontaneously emits such radiation is considered radioactive.
The reason radioactive isotopes emit radiation is that the emission of radiation is a nutural consequence of being radioactive. Let's look a bit more closely. Radioactive isotâ¦opes are unstable atoms, and they will undergo radioactive decay sooner or later. The unstable atomic nuclei undergo a change based on what particular isotope is being considered. In any case, when a nuclear change occurs, radiation of some kind is emitted from that nucleus. It really is that simple.
