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.
