Radiometric Dating - Types
One example of scientists not accepting radiometric dates is that of Mungo Mana human fossil from New South Wales. This is a third, imbued with radiometric dating magazine. Exposure to sunlight or heat releases these charges, effectively "bleaching" the sample and resetting the clock to zero. In the figure, that distinct age range for each fossil species is indicated by the grey arrows underlying the picture of each fossil. Why Science Matters. Like carbon, potassium has three natural isotopes, one of which is radioactive.
