ESR studies of low energy irradiated tooth enamel. In: INTERNATIONAL CONGRESS ON SOLID STATE DOSIMETRY, 14th, 2004, New Haven, Estados Unidos. <b>Proceedings...</b> Disponível em: http://repositorio.ipen.br/handle/123456789/17492.http://repositorio.ipen.br/handle/123456789/17492Hydroxyapatite is one of the most promising material for retrospective and accident dosimetry. In this paper we provide an analysis of the ESR spectra of X and g-irradiated synthetic B-type carbonated hydroxyapatite, compared with biological hydroxyapatite (tooth enamel). The energy dependence of the synthetic and biological hydroxyapatite ESR signal irradiated with low energy photons (14.3 – 21.2 keV) in the dose range between 0.2 and 5 Gy was studied aiming to span the energy response curve for energies lower than 30keV, extensively studied in the range between 30 keV, 60Co until 2.5MeV. The samples were irradiated at room temperature and the measurements were carried out 48h after irradiation.openAccesselectron spin resonanceteethenamelsenergy dependencelow dose irradiationTexto completo de eventohttps://orcid.org/0000-0001-7137-0613https://orcid.org/0000-0002-6704-1910
