With its discovery in 1896, radioactivity opened up a Pandora's box of questions and revealed a new world, waiting to be explored in the microcosm of the atomic nucleus. Radioactivity is a very interesting phenomenon in nature.

Classical Electromagnetism cannot explain radioactivity. It's a spontaneous and random phenomenon whereby nuclei of certain chemical elements like Uranium, radiate gamma rays (high frequency electromagnetic radiation), beta particles (electrons or positrons) and alpha particles (Helium Nuclei).

"In a billion years [from now], it seems, intelligent life might be as different from humans as humans are from insects . To change from a human being to a cloud may seem a big order, but it's the kind of change you'd expect over billions of years." Freeman Dyson, Statement made in 1986, quoted in Asimov's Book of Science and Nature Quotations, p. [American mathematician.]"Slowness has really nothing to do with the question.This article has a comprehensive list of radioactive elements and their properties.This Buzzle article has a list of radioactive elements that abound in nature, arranged in the order of increasing atomic number, along with their decay modes. Radioactivity arrived on the scene of world physics in the 19th century, just when people thought they knew everything in physics.Presently, nature appears to be more steady, more firm and more refractory [resistant] to changes than we thoughtbefore we had made a clear distinction between hereditary variability [within species] and acquired characteristics [DNA characteristics fixing each species]. Salet, Hasard et Certitude: Le Transformisme devant la Biologie Actuelle (1973), p. Several methods for dating ancient materials have been developed.This is an important topic, for evolutionists want the history of earth to span long ages in the hopes that this will make the origin and evolution of life more likely.Yes, an understanding of dating methods is important, but we should keep in mind that whether or not these dating methods are accurate, really has no direct relation to whether evolution has ever occurred or could occur. Evolution can only occur by a sequence of, first, production of matter from nothing, or origin of matter.This was dealt with in the chapter by that name (chapter 1).The basis for assuming that like fossils indicate contemporary formation is faunal succession.However, as previously noted, times of volcanism and metamorphism, which are both critical parts of global processes, cannot be correlated by fossil content.By the emission of these particles and radiation, the unstable nucleus gets converted into a stabler nucleus. The Term 'Radioactive' - A Misnomer A radioactive element is a fundamental element whose atomic nuclei demonstrates the phenomenon of radioactivity.The name 'radioactive' may suggest to you that radioactive elements radiate radio waves, but unfortunately that is not so!
