Revision questions 1 thediagram belowshows the movementof a number. Libby, the discoverer of the c14 method, which won for him a nobelprize, expressed his shock that human artifacts extended back only5000 years, a finding totally in conflict with any evolutionaryconcept.
Alpha decay occurs when analpha particle (a helium nucleus), consisting of two protons andtwo neutrons, is ejected from the nucleus of the parent isotope. Thissuggests that, given the current annual rates of erosion (some 27. So if we take a lava flow and date several minerals forwhich one knows the daughter element is excluded, we should always getthe exact same date, and it should agree with the accepted age of thegeological period. Im not posting about the directsciences of any of this. Rock known to beless than 300 years old is variously dated between 50 million and14. The ions produced are forced into a magneticfield where the different mass of the carbon isotopes causes adifferent deflection, allowing the quantity of each isotope to bemeasured. Its true that carbon dating doesnt work on coal that isloaded with radioactive thorium.
