Abstract:

There are many international and non-governmental organizations in order to use the radiography method, which has many areas such as industry, health, security, agriculture, art and archeology. In addition to the international organizations that set the standards and limitations on radiation, there are national institutions in each country that carry out authorization, monitoring and inspection procedures regarding radiation. The radiography method is based on the principle that ionized radiation emanating from the radiation source passes through the substance and creates an image. The ionizing radiation used in radiography has four basic effects on substances and humans: electrical, photochemical, fluorescent and biological. Among these effects, although the biological effect is extremely harmful and dangerous for living things; other effects are used for human benefit. This method, which is frequently used in the control of welded manufactures in shipyards, takes an average of 8,500 shots per year in the light of the latest data on shipbuilding projects in Turkey. Considering the risks in the shipyard, the risks of the radiography applied in this study; It has been examined under three headings: device sourced, personnel sourced, and organization sourced. Risk analysis and assessment of the identified risks were made using the 5×5 matrix method. The reasons for the risks and the measures to be taken against these risks are explained.
