The formation of highly oxidizing radicals in multifunctional-solid compounds upon irradiation with gamma-ray had been investigated. Five organic compounds having a single carbon ring had been used in the present investigation; these materials are 1-chloro-4-nitrobenzene, 4′-aminoacetophenone, 3′-hydroxyacetophenone, n -anthranilic acid, and triphenylmethane. These material were irradiated using 60 Co radiation with different doses between 20 and 100 kGy. Electron spin resonance spectroscopy spotted increases of the resonance absorption having landé factor around 2.0113 ± 0.003 upon irradiation with the increasing of dose. This resonance absorption was related to the formation of long-lived oxygen radicals that were attached to one of the radiation synthesized compounds. The method of infrared absorption spectroscopy emphasized the formation of cyclic and aliphatic hexane in addition to the active oxygen radicals. n -Anthranilic acid was found to be suitable for radiation the dosimetry with long-lasting radiation signature as electron spin and also to determine the exposure dose. The time-lapse infrared and electron spin resonance measurements had been used to tracked the formation of active species within the time-lapsed after the end of exposure; results showed that the dosimetric signature may be used as a tracker for the time when the exposure happens.

伽马射线辐射对具有碳环的有机化合物的影响及其在剂量学中的应用

已经研究了在γ-射线辐照下多功能固体化合物中高氧化性自由基的形成。在本研究中使用了五个具有单个碳环的有机化合物。这些材料是1-氯-4-硝基苯，4'-氨基苯乙酮，3'-羟基苯乙酮，正邻氨基苯甲酸和三苯甲烷。使用60 Co放射线以20至100 kGy之间的不同剂量辐照这些材料。电子自旋共振光谱法发现随着剂量的增加，共振吸收增加，具有在2.0113±0.003附近的landé因子。这种共振吸收与长寿命氧自由基的形成有关，该氧自由基与辐射合成的化合物之一连接。红外吸收光谱法强调除了活性氧自由基外还形成环状和脂肪族己烷。发现n-邻氨基苯甲酸适用于以电子自旋的方式具有持久的辐射特征的辐射剂量学，并且还可以确定暴露剂量。延时红外和电子自旋共振测量已用于跟踪曝光结束后经过的时间内活性物种的形成。结果表明，当暴露发生时，剂量学特征可以用作跟踪器。延时红外和电子自旋共振测量已用于跟踪曝光结束后经过的时间内活性物种的形成。结果表明，当暴露发生时，剂量学特征可以用作跟踪器。延时红外和电子自旋共振测量已用于跟踪曝光结束后经过的时间内活性物种的形成。结果表明，当暴露发生时，剂量学特征可以用作跟踪器。
