Elektron paramagnetik rezonans (EPR)tekniği ile diş minelerinin almış olduğu radyasyon dozunun belirlenmesi
Özet
Radiation Dose Measurement By Electron Paramagnetic Resonance (EPR) Of Tooth Enamel The aim of this study was to examine radiation dose by using the EPR method of the extracted teeth which were collected from 97 individuals who are living in the Black Sea Area. The enamel of the teeth were substracted from the dentin using chemical and mechanical separation processes. The enamel seperated in an agate mortar the partical size was designated to be 125-600 μm. The EPR spectra of the systems was amanged in this which EPR measurements AU Calibration is performed at the Nuclear Science Institute for the creation of irradiation Medicine Hospitals located in Radiation Oncology Radiotherapy Unit; DBX brand Varian Linear Accelerator (Linac) was used for this purpose . Radiation doses were determined using the resulting calibration curve. Of all 97, 71 people's radiation dose were below 95 mGy , thus the radiation dose measurements could not be made. The remaining 26 persons were calculated. From the rest 26 people's, 11 of them were over 95 mGy but less then 1 Gy were classified as long. This subtracted dose from the thyroid gland control or various imaging methods. 15 people over 1 Gy is calculated seperately, the statistical evaluation revealed no significant difference between over 1 Gy and below 1 Gy inters of subtracted radiation dose. Dose calibration curve calculated that the higher values for the subtracted radiation levels results from the patients various imaging methods. In the study, the threshold dose for calibration curve for dental enamel was found to be 95 mGy. Further studies should make with the individuals without any medical exposures, using deciduous teeth instead of permanent teeth. Moreover, the techniques as well as long term with longer studies groups must be included for this purpose.
