102527 Advanced Gamma Spectroscopy Lab.

Course Goals:

The main aim of this course is to learn all steps of the gamma-ray spectroscopy technique and apply it to routine environmental and indistrial samples in addition to the skill and knowledge gained in nuclear instrumentations and basics of radiation detection device uses taught by other Courses given in Health Physics Master Science and Medical Physics programs. The Course also aims to provide sufficient detailed information and skill on the determination of activity contained in samples as well as saple peraparation and counting methods, operation of spectrometers, spectrum evalation and the nessary softwares by hands-on experience in the lab.

Course Learning Outcomes:

Students will be able to carry out measurement professionally and edit analysis report in private or public laboratories engaged in radionuclide metrology. When students graduate, they will be able to measure routin radioactivity in spatial institutions such as TAEK, Tübitak. In this lecture, they will learn gamma radioactivity measurement in accordance with ASTM E181, ANSI and other ISO/EN standards, become skilful at application of measurement methods in a laboratory which is accredited in accordance with TS/EN/ISO/IEC 17025 standards, so they will take advantage in getting a job or installation their own laboratory. Besides, they will have ability to contribute to the scientific studies in advanced gamma spectroscopy laboratories.
