Intercomparison of EPR-dosimetric techniques using tooth enamel had been performed in order to check whether the results produced by different laboratories are consistent and accurate. Participants were supposed to evaluate doses applied to pulverized enamel samples, using routine techniques from their laboratories. The intercomparison has demonstrated a great variety of methods used for dose reconstruction. Peculiarities of experimental approaches are discussed systematically in terms of procedure for recording the EPR-spectra, determination of the amplitude of the radiation induced signal, determination of the dose, and error propagation.
为了检查不同实验室得出的结果是否一致且准确，已经对使用牙釉质的电子顺磁共振剂量测定技术进行了比对。参与者应使用其实验室的常规技术评估施加于研磨后的牙釉质样品的剂量。比对结果表明，用于剂量重建的方法多种多样。从电子顺磁共振光谱记录程序、辐射诱导信号幅度的测定、剂量的测定以及误差传播等方面，系统地讨论了实验方法的特点。
