Types of radioactive emission

Answer 1

The nuclei of radioactive elements may emitt one or more of the following; Gamma Rays --- very energetic electromagnetic wave pulses Beta Negative Rays --- electrons Beta Positive Rays ---- positrons (positive electrons) Alpha Rays ------ a composite particle consisting of 2 neutrons & 2 protons.

Answer 2

Natural radioactivity is exhibited by several elements, including radium, uranium, and other members of the actinide series, and by some isotopes of lighter elements, such as carbon-14, used in radioactive dating. Radioactivity may also be induced, or created artificially, by bombarding the nuclei of normally stable elements in a particle accelerator. Essentially there is no difference between these two manifestations of radioactivity. The radiation produced during radioactivity is predominantly of three types, designated as alpha, beta, and gamma rays. These types differ in velocity, in the way in which they are affected by a magnetic field, and in their ability to penetrate or pass through matter. Other, less common, types of radioactivity are electron capture (capture of one of the orbiting atomic electrons by the unstable nucleus) and positron emission-both forms of beta decay and both resulting in the change of a proton to a neutron within the nucleus-an internal conversion, in which an excited nucleus transfers energy directly to one of the atom's orbiting electrons and ejects it from the atom.

Answer 3

Radioactive emissions include x-rays, beta particles, alpha particles, and gamma rays. They are the emissions from forms of spontaneous radioactive decay.
