Course Details Language of Instruction Turkish Level of Course Unit Associate Degree Department / Program Non Destructive Testing Mode of Delivery Face to Face Type of Course Unit Compulsory Objectives of the Course application, qusetion and answer Course Content Electromagnetic waves (radiation) that have high energy can penetrate a lot of materials. Radiation that can penetrate a certain material can effect films that have been placed at the other side of the material and which are sensitive to radiation. When these films are put through the developing process, the picture of the inside part of the material appears. This material is the one through which radiation has gone. This picture appears due to the empty spaces or changes in thickness/density inside the material. Imaging of the inside of a material in this way is called radiography. If a dedector is placed in lieu of a film and if the radiation that has passed through the material is collected in this detector and this collected radiation is tranfered to a monitor, then, this teechnique is called Radioscopy. It can be used to detect volumetric and surface deviations that are anticipated in all metalic and non metalic materials. Various types of radiation sources can be used for radiographic testing. These sources can be X-ray tubes or isotopes that produce Gama rays. In industrial radiography, X-ray energy interval is usually between 50 kV and 350 kV. The level of radiation energy changes according to type and the thickness of the material to be radiated. The most widely known and used sources of Gama are Ir 192 and Co 60. Isotopes such as Se 75, Yb 169 and Tm 170 are also used in the industrial radiography field. Tests should be done in a way that is in accordance with the standards so that sound and reliable results can be obtained. These standards are prepared according to the type of material and/or product. Additionally, there are application standards that are geared towards the way the tests are done as well as other application standards which have levels of acceptance that have been specified. Testing is done by determining the proper standards based on the properties of the testing piece Course Methods and Techniques Prerequisites and co-requisities None Course Coordinator None Name of Lecturers Instructor Kadir Koçak Assistants None Work Placement(s) No Recommended or Required Reading Resources GEV Radrografik muayene eğitim notu Non Destructive Testing and Quality Control, Vol 17, Metals Handbook, 10th ed., ASM, 1989 1- provision of radiographic examination skills 2- Being informed about the standards and reporting yazılı sınav, uylulama Course Category Mathematics and Basic Sciences %20 Science %10 Field %70
