Vedclass · Answer

(B) Electron Spin Resonance $(ESR)$ dating is a technique used to determine the age of materials found in archaeological sites.Many materials at these sites trap electronic charges due to bombardment by radioactive radiation from the surrounding sediment.The presence of these trapped charges can be detected using $(ESR)$ spectroscopy.The intensity of the $(ESR)$ signal serves as a measure of the accumulated radiation dose,which is directly proportional to the age of the fossil.Tooth enamel is commonly found at archaeological sites and is highly suitable for $(ESR)$ dating,offering a precision of about $10-20\, \%$.This method is crucial for dating sites related to the biological and cultural evolution of modern humans,thereby helping to revise the evolutionary timeline for various groups of organisms.
