Mankind has been aware of the existence of radioactivity since 1896 and the discovery that rays emitted from uranium were capable of passing through thin metal plates. That discovery
was followed by the work of Pierre and Marie Curie, a husband and wife team that was successful in isolating certain radioactive elements. Eventually, radiation would be subcategorized into alpha
particles, beta particles, and gamma rays. Each of these categories of radiation has its own distinctive qualities. Each presents certain threats in terms of human health but each
is also beneficial in allowing us to explore certain aspects of our world. Ernest Rutherford, the physicist that ultimately would be responsible for
discovering the three categories of radiation, made his earliest contributions to the field using a radio detector that was capable of detecting electromagnetic waves (Morrison, 1984). Much of Rutherfords
earlier work with the magnetization of iron by High-Frequency Discharge was utilized in this pursuit since the device depended on an innovative magnetizing coil constructed of tiny bundles of magnetized
iron wire (The Nobel Foundation, 1999). Rutherfords attention was captivated in January 1896, however by the published discovery of X rays (Morrison, 1984). Rutherford, accompanied by his partner
J.J. Thomson, immediately set out to work in the new field which had opened up with this singular discovery (Morrison, 1984). Their first work concentrated on the behavior of
ions in X-ray treated gases (The Nobel Foundation, 1999). Rutherford ultimately discovered the atomic nucleus. He was particularly entranced with radioactivity and discovered and named alpha and beta
rays in uranium radiation in 1898 (The Nobel Foundation, 1999). Since Rutherfords initial discoveries physicists have found that this knowledge can be applied to a variety of very diverse
