	Encyclopedia: List of stable isotopes
		Isotopes are atoms of a chemical element whose nuclei have the same atomic number, Z, but different atomic weights, A. The word isotope, meaning at the same place, comes from the fact that isotopes are located at the same place on the periodic table.
		Note that tungsten and bismuth do have isotopes which are very slightly radioactive; these have been excluded from this list, which strictly limits to entirely stable entities.
		Deuterium (symbol 2H) is a stable isotope of hydrogen with a natural abundance of one atom in 6500 of hydrogen.

		This means that different isotopes of an element will have different masses, since both the protons and the neutrons contribute about equally to the mass of an atom.
		Once the precise atomic masses of each isotope, and their relative abundances are known, the average mass of the isotope as found in nature can be calculated.
		Lead's isotopic abundance is one of the least reproducible because various isotopes are the final products of the radioactive decay of a number of heavy elements.

	Isotopes Project, LBL
		Isotope Explorer Version 2.2 (PC Windows 95/98/NT), a WWW-based software for searching, extracting, and displaying information from ENSDF and NSR, was released in January 1999, and the Internet Isotope Explorer Version 3.0 (JAVA/HTML) is now available.
		Additional publications from the Isotopes Project are the Table of Radioactive Isotopes, John Wiley & Sons, Inc., published in 1986, and the Table of Superdeformed Nuclear Bands and Fission Isomers (in collaboration with McMaster University, Canada), in Nuclear Data Sheets 97,241 (2002), on the Table of Isotopes CD-ROMs, and on the Internet.
		The Project established an Educational WWW site in 1998, Exploring the Isotopes, with a periodic table interface to data on all isotopes for each element, and a Glossary of Nuclear Science Terms.

		Some of the isotopes produced by the U.S. Department of Energy (DOE) are used to support vital research that could lead to major breakthroughs in the treatment of disease.
		One of the most promising of these involves the use of radioactive isotopes (radioisotopes) called "alpha-emitters" and "beta-emitters." These are radioisotopes that emit particles capable of destroying cancer cells and reducing tumors.
		Methods of linking radioactive isotopes to these homing materials were also discovered, resulting in so-called "smart bullets" that can be delivered directly to the locations of cancer cells.
