title: A comparative thermoluminescence and electron spin resonance study of synthetic carbonated A-type hydroxyapatite.
abstract: Intensity of the 150°C thermoluminescence peak of beta-irradiated carbonated synthetic A-type hydroxyapatite is approximately 12 times higher than that of the noncarbonated material. Deconvolution of the glow curve showed that this peak is a result of a trap distribution. An attempt was made to relate this thermoluminescence peak enhanced by carbonation with the ESR signal of the CO(2)(-) radical in natural or synthetic hydroxyapatite.
