Zusammenfassung: | In this study, gamma rays were applied to the sulfadimethoxine, pyrazinamide, and chloramphenicol in the dose range of 1-15 kilogray, in order to
detect radiosensitivity of paramagnetic species, which are formed after
irradiation by electron paramagnetic resonance spectroscopy. Firstly, the intensities of
electron paramagnetic resonance signals of the samples as a function of the
microwave power were investigated at room temperature. While no signal was
obtained from the unirradiated samples, the irradiated samples exhibited
significant spectra. Additionally, the time dependency of the samples was
analyzed to study the stability of the radicals.
Bu çalışmada, elektron paramanyetik rezonans
spektroskopisi ile ışınlama sonrası oluşan paramanyetik türlerin radyasyon
duyarlılığını saptamak için sülfadimetoksin, pirazinamid ve kloramfenikol
numunelerine 1-15 kilogray dozunda gama ışınları uygulandı. İlk olarak, numunelerin elektron paramanyetik rezonans sinyal
şiddetleri, mikrodalga gücünün bir fonksiyonu olarak oda sıcaklığında
incelendi. Işınlanmamış örneklerden herhangi bir sinyal elde edilmezken,
ışınlanmış numuneler belirgin spektrumlar sergiledi. Ek olarak, radikallerin
kararlılıklarını incelemek amacıyla numunelerin zamana bağımlılığı analiz
edildi. |
