Electron Paramagnetic Resonance Study of Carbonated Hydroxyapatite Synthesized through Calcium Phosphate Cements

August 5, 2022
Author(s)
Alline F. Myers, Shozo Takagi, Stanislav Frukhtbeyn, Laurence Chow, Veronika Szalai, Lonnie Cumberland, Ileana Pazos, Eaman Karim
Ionizing radiation-induced paramagnetic defects in calcified tissues like tooth enamel are indicators of irradiation dose. Hydroxyapatite (HA), the principal constituent in these materials, incorporates a variety of anions (CO32, F, Cl, SiO44 ) and

Recommended Dose Calculation Formalisms and Consensus Dosimetry Parameters for Intravascular Brachytherapy Dosimetry: An Update of the 1999 AAPM Task Group 60 Report
