The preceding DIN 6800-2 (1997) protocol has been revised by a German task group and its latest version was published in March 2008 as the national standard dosimetry protocol DIN 6800-2 (2008 March). Since then, in Germany the determination of absorbed dose to water for high-energy photon and electron beams has to be performed according to this new German dosimetry protocol. The IAEA Code of P...
OC-0073: Difference in using the TRS-398 code of practice and TG-51 dosimetry protocol for FFF beams
The water phantom is used for LINAC calibration to measure absorbed dose radiation. Practically, it requires a long preparation time and considered less efficient. To increase efficiency, the medical physics team in hospital uses slab as tool. Consequently, correction factor crucial define equivalence of doses resulted from phantom. measurement was performed according IAEA TRS-398 dosimetry pro...
The Brazilian Institute of Radiation Protection and Dosimetry (IRD/CNEN) carried out quality assurance regulatory audits in Brazilian radiotherapy facilities from 1995 to 2007. In this work, the set of data collected from 195 radiotherapy facilities that use high-energy photon beams are analyzed. They include results from audits in linear electron accelerators and/or Co-60 units. The inspectors...
