Simple definition of radioactive dating

The energies involved are so large, and the nucleus is so small that physical conditions in the Earth (i.e. The rate of decay or rate of change of the number N of particles is proportional to the number present at any time, i.e.The half-life is the amount of time it takes for one half of the initial amount of the parent, radioactive isotope, to decay to the daughter isotope.Alpha decay of the The sum of the mass numbers of the products (234 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 2) is equal to the charge on the parent nuclide.Nuclei can also decay by capturing one of the electrons that surround the nucleus.

Since its radioactivity presents a serious health hazard (see radiation sickness), disposing of such material is a great problem......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......Other corrections must be made to account for the proportion of throughout the biosphere (reservoir effects).Additional complications come from the burning of fossil fuels such as coal and oil, and from the above-ground nuclear tests done in the 1950s and 1960s.
