Lecture Notes (Radioactivity) Radioactivity: - one of the first and most important clues to an understanding of the nucleus occurred with the discovery of the phenomenon later known as radioactivity in early 1896 by the French physicist Henri Becquerel - it was another one of those "accidents" that illustrate how the Radiation Physics Lecture Notes Wordpress Bestselling Radiation Physics Lecture Notes Wordpress ebooks, help topics, and PDF articles to fit every aspect of your life. Home Physics Notes PPT [Physics Class Notes] on Applications of Radioactivity Pdf for Exam. An electron is not part of the atomic nucleus, but orbits, the nucleus. Thats the reason why atoms of Plutonium, Uranium are extremely unstable and undergo the phenomenon of radioactivity. The chance of encountering instability increases as the size of the nucleus increases because the mass of the nucleus becomes a lot when concentrated. A nucleus that spontaneously destroys part of its mass to emit radiation is said todecay(a term also used to describe the emission of radiation by atoms in excited states). The force divided by the area is PRESSURE. RI$I$$HI'I)$IJI$R$JRI$I$$I)I$JRI$I$$I)I'I%)$AJI$R$JRI$I$$I)I$JRI$I$$I)I$JRI$tRI$I%)$IJI$R$JRI$I$$I)I$ 5.5-Revision-Notes-Radioactive-decay . Radioactivity is the spontaneous breakup of the nuclei of unstable atoms, which releases radiation in the form of fast-moving particles or high-energy electromagnetic waves ( gamma rays ). Two radioactive substances Q and X are being observed by researchers, with equal amounts at the start of the experiment.
