Assessment of Radiation Dose Calibrator Performance in the Nuclear Medicine Department of the National Cancer Institute –Wad Madani

Abstract

Nuclear medicine uses many different radioactive isotopes for radiation diagnostic studies and for therapy . The amounts of radioactivity has to be determined exactly before it is applied to patients. The dose calibrator has to measure the radioactivity of gamma and beta with different energies precisely for high quality imaging and for applying the right amount of radiation to have good images which give good diagnosis and effective treatment of diseases . This study was carried out to assess the performance of dose calibrator which is used in nuclear medicine in the National Cancer Institute –wad madani (Gazera state) . The study period was from October 2015 to February 2016 . Four quality control tests were carried out using standard radionuclide , 137Cs . The tests included accuracy ,constancy ,linearity and Geometry .All results that were obtained from the study were compared with the international standard (±5%) and the results showed that the dose calibrator under the study was of good performance and there is no need for any correction tables or factors or maintenance for the time being.
