Abstract
Electron spin resonance (ESR) dating is currently one of the major dating techniques in archaeology, paleoanthropology, and paleontology. Years of experience have led to some standard protocols for ESR dating. However, these limit studies because some tooth enamel samples fail the criteria in the protocols. One criterion is that the enamel must be completely free of dentine. There are tooth fragments that are so small that complete cleaning would not leave enough enamel for dating. To see if this standard protocol is absolutely required, several samples of “dirty” enamel were compared. The results confirm the need for essentially complete cleaning.
期刊介绍：
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
