Radiation oncology is a relatively young specialty that has evolved as a subspecialized discipline over the past 30 years. Although the use of radiation for therapeutic purposes has been studied for the last century, it has only been relatively recently that the formal specialty has been recognized. Originally, training in the use of radiation for therapeutic purposes was included as part of di...

Recent works focused on bremsstrahlung radiation as a non-invasive tool for monitoring proton beams used in radiobiology (>20 MeV). In order to study the validity of theoretical models cross sections, X-rays between 4 keV and 15 coming from carbon target irradiated by energy range MeV 50 were measured silicon drift detector. The obtained data vary 10 mb keV−1 1000 fit well literature with model...

On13–14, June 2011, at the R.E. Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology of National Academy of Sciences of Ukraine the first Ukrainian-Swedish Workshop “New approaches to diagnostics and treatment of cancer” was held. Karolinska Institutet (Sweden) and Odesa National Medical University were the co-organizers of the Workshop. The Director of the R.E. Kavetsky Inst...

A founding concept of radiobiology that deals with X-rays, γ-rays and ultraviolet light is that radiation indiscriminately damages cellular macromolecules. Mounting experimental evidence does not fit into this theoretical framework. Whereas DNA lesion-yields in cells exposed to a given dose and type of radiation appear to be fixed, protein lesion-yields are highly variable. Extremely radiation ...

Target theory is one of the essential concepts for understanding radiation biology. Although many complex interpretations of target theory have been developed, its fundamental principle is that ‘inactivation of the target(s) inside an organism by radiation results in the organism’s death’. The number of ‘targets’ and the locations of these ‘targets’ inside an organism are not always clear, alth...

BACKGROUND Although ionizing radiation is very important in diagnostic and treatment of many diseases, the hazards of this radiation are considerable and irrefutable. One of the main stages in radiation protection is knowledge about radiation dose in radiological investigation. The aim of this study was to determine the physicians' knowledge in radiological examinations. MATERIAL AND METHODS ...
