Finding conformity of determination for annual qualty control of monitor ionization chamber which is in the head structure of linear accelerator treatment device which is used for radiotherapy

In this thesis study Monitor İonazation Chamber which is contained in Siemens brand, Oncor Impression Plus model linear accelerator?s head structure which is available was examined in repeatability, linearity and authority of stopping treatment on given monitor unit by the reference of British Journal of Radiology (BJR). Calculation of limit value evaluation which is international standard of these tests was done according to received measurement with using two teleportation methods for end effect. Constancy of radiation and productivity of short and long term stability were calculated theoretically. As a result of this study, it is established that the received data are relevant for international standardsKey Words: Monitor ion chamber, qualty control, elektron, x beam, radiation accent
