Absolute Dosimetry

Clinical dosimetry with ionization chambers according to the international Code of Practice IAEA TRS 398 - in theory and practice

 

The course provides in a compact way well-founded expertise about IAEA TRS 398 "Absorbed Dose Determination in Photon and Electron Beams" and the changes and innovations planned in this standard.  
It is aimed at beginners and medical physicists with little experience in the dosimetry of medical linear accelerators who want to acquire the necessary basics and knowledge in a relaxed atmosphere and offers a balanced mixture of theory and practice.

Thus, the central requirements of IAEA TRS 398 are presented in detail and their implementation deepened by means of numerous case studies and practical exercises. In addition to recommended measuring methods with reference ionization chambers and suitable calibrated detectors, the focus is on the determination of important correction factors and the treatment of typical problems in absolute dosimetry.   

Look forward to a practical course with experienced experts!
