Electron spin resonance dating of tooth enamel
Abstract
The amplitude of the electron spin resonance (ESR) peak at g = 2.0018 for hydroxyapatite of fossil tooth enamel can be used to measure the acquired radiation dose (AD) and thus the time (T) since burial of the tooth in a sediment. No significant fading or saturation occurs up to at least 1 Ma, permitting dating of middle Pleistocene deposits. AD is determined by the additive-dose method, using a sufficiently large modulation amplitude to avoid …
