Radtke, U. It was presumed that the tooth enamel came from a collective burial consisting of 23 people, involving men, women and children. Duval et al. Canadian Journal of Earth Sciences Free radicals:
Equid teeth are also appropriate, although it should be taken into account that the porosity of the cement covering the external side of the enamel can lead to some issues regarding U-uptake modelling.
Electron Spin Resonance Dating
The tooth enamel was irradiated with gamma rays and the resulting free radicals were measured using an electron spin resonance ESR X-band spectrometer to obtain a signal intensity compared to absorbed doses curve. Mania, D. Electron spin resonance dating can be described as trapped charge dating. Finding the dose rate to convert D A into an age is a crucial step after D A has been found. By definition, field work is the first step of the ESR dating procedure, and the reliability of the age result depends on the accuracy of the data collected on site, such as the position of the tooth and its embedding sediment, the in situ dosimetry measurements and the estimation of the thickness of the overlying deposits. Toyoda, S. ESR dating accuracy was obtained relatively straightforwardly, using just a few grams of tooth enamel, thereby highlighting some of the advantages and characteristics of the ESR dating method.
