Retrospective dosimetry technique of tooth enamel ESR and its application in dose reconstruction

As a retrospective dosimetry technique, electron spin resonance has been applied to dose reconstruction wider and wider. Principle and outline of the ESR tooth enamel dose assessment are described, includ the collection and preparation of samples, the measurement and signal processing, dose calibration of ESR response interpretation of results, souces of error and the latest achivement. In addition, some examples of dose reconstruction by ESR using tooth enamel are given.
