Opis:: Ionizing radiation is commonly used in diagnostic and therapeutic applications in medicine. Therefore, both staff and patients are exposed to the biological influence of radiation. Biological effects and damages are proportional to the irradiation.In this study the radiation dose to human in the patient room and the technician room at computed tomography and X-ray units were measured and compared for different situations.

Opis:: People are exposed to both internal and external radiation from the natural radiation sources. For this reason, studies determining the natural radiation level are made to detect the effects of radionuclides, that constitute the natural radiation sources, on the environment and especially the effects of radiation on people and on biological systems. The most common radiation sources are ²³⁸U, ²²⁶Ra, ²³²Th and ⁴⁰K radioisotopes. In this study, in the samples of the rock and soil acquired from Amasya Şeyhcui Region, the activity concentrations of ²²⁶Ra, ²³²Th and ⁴⁰K are determined by using NaI (Tl) detector with gamma spectrometer and are compared with the limit values.

Opis:: The electric and magnetic properties of Cu doped and pure/undoped hydrogels were investigated by impedance spectroscopy and electron spin resonance techniques, respectively. The capacitance and dissipation factor (tan δ) were measured in the frequency range of 100 Hz-10 MHz at room temperature. The Cole-Cole plots for the Cu doped dry and pure dry hydrogels have been used to describe the characteristic change of electrical properties in mentioned temperature interval. The comparison between Cu ions doped and pure/undoped samples is done using the impedance spectroscopy and the electron spin resonance techniques. Electron spin resonance signal for pure, Cu doped wet and Cu doped dry samples are not any power absorption signal, near the symmetric with respect to the resonance field values according to the dry sample and asymmetric for resonance field/base line, respectively.
