Electron paramagnetic resonance (EPR) with tooth enamel is a method extensively used for retrospective external dosimetry. Different research groups apply different equipment, sample preparation procedures and spectrum processing algorithms for EPR dosimetry. A uniform algorithm for description and comparison of performances was designed and implemented in a new computer code. The aim of the paper is to introduce the new software 'EPR-dosimetry performance'. The computer code is a user-friendly tool for providing a full description of method-specific capabilities of EPR tooth dosimetry, from metrological characteristics to practical limitations in applications. The software designed for scientists and engineers has several applications, including support of method calibration by evaluation of calibration parameters, evaluation of critical value and detection limit for registration of radiation-induced signal amplitude, estimation of critical value and detection limit for dose evaluation, estimation of minimal detectable value for anthropogenic dose assessment and description of method uncertainty.
利用牙釉质进行电子顺磁共振（EPR）是一种广泛用于回顾性外照射剂量测定的方法。不同的研究团队在EPR剂量测定中使用不同的设备、样品制备程序和谱处理算法。在一个新的计算机代码中设计并实现了一种用于描述和比较性能的统一算法。本文的目的是介绍新软件“EPR剂量测定性能”。该计算机代码是一个用户友好的工具，可全面描述EPR牙齿剂量测定的方法特定能力，从计量特性到应用中的实际限制。为科学家和工程师设计的该软件有多种应用，包括通过评估校准参数支持方法校准、评估辐射诱导信号幅度记录的临界值和检测限、估计剂量评估的临界值和检测限、估计人为剂量评估的最小可检测值以及描述方法不确定度。
