The name 'radioactive' may suggest to you that radioactive elements radiate radio waves, but unfortunately that is not so!The name 'radioactivity' is a misnomer because these elements have nothing to do with radio waves! To understand radioactivity, we need to explore the structure of an atomic nucleus.
actinide series,a series of radioactive metallic elements in Group 3 of the periodic table.
Members of the series are often called actinides, although actinium (at. 89) is not always considered a member of the series......
Depleted uranium is used as shelding to protect tanks, and also in bullets and missiles.
The first atomic bomb used in warfare was an uranium bomb.
The quantitative approach is admirable, but Buffon's assumptions are flawed. Silicate minerals have lower heat conductivity than steels and are better insulators leading to slower cooling rates.
Second, the calculations did not incorporate the heating effects of radioactive decay.nucleus,in physics, the extremely dense central core of an atom.The Nature of the Nucleus Composition Atomic nuclei are composed of two types of particles, protons and neutrons, which are collectively known as nucleons......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).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.radiation sickness,harmful effect produced on body tissues by exposure to radioactive substances.
