- W138801019 abstract "In 1895, Henri Becquerel discovered that some uranium salts emit penetrating radiation that can be made visible with ordinary photographic emulsions. This discovery was the beginning of nuclear science. Today we know that most natural radioactivity is due to a few very long-lived unstable isotopes that were formed 4.5 × 109 years ago. At that time the Earth was formed, and presumably, a very large number of different radioactive isotopes were produced. Those with a shorter half-life have all decayed and only those with a very long half-life still exist today. The isotopes contributing most to the natural radioactivity are uranium-235, uranium-238 and thorium-237. The half-life of each of these isotopes is listed in Table 3.1. After a long decay chain with a succession of alpha and beta emissions, these isotopes eventually decay to stable lead (206Pb). There are many other isotopes with a very long lifetime occurring naturally; the most important of these is potassium-40. Several short-lived isotopes also occur naturally; these are either decay products of long-lived isotopes or are produced by cosmic rays. It is worth mentioning radon-222, which is an alpha emitter with a half-life of 3.8 days. This isotope is produced in the decay of uranium. Although in general it is very rare, it can occasionally be found in high concentrations inside buildings or in thermal springs and can represent a health hazard." @default.
