This standard specifies the instruments and equipment involved in EPR dose reconstruction using enamel, enamel preparation, EPR spectrum measurement, dose estimation and uncertainty expression. This standard applies to the reconstruction of the absorbed dose of the teeth of the over-exposed personnel caused by acute and chronic external exposure. Applicable absorbed dose range: 0.5 ~ 300Gy; radiation and its energy range: >200keV photon radiation. This standard does not apply to dose estimation for internal exposure.
