Quality Control Testing of Dose Calibrators
نویسنده
چکیده
We have reviewed quality control testing of dose calibrators and have analyzed the potential for error. The uncertainty in half-lives of reference sources can lead to inaccurate assessment of the accuracy and constancy in dose calibrator performance. Molybdenum-99 contamination of '"Tc used as a reference source can appear as a nonlinear response of the dose calibrator. The useful life of a reference source and the tolerable amount of Mo contamination are examined. Key Wonts: dose calibrator; accuracy; constancy; linearity; geometry; quality control

An investigation on the performance of dose calibrators in nuclear medicine centers in Iran
Background: To investigate the status of the nuclear medicine (NM) centers in Iran for the performance of dose calibrators, 18 out of 54 centers providing NM services in Iran were randomly selected and inspected in 1997. In the first phase of the study the selected centers were inspected for performing of quality control (QC) tests of dose calibrators. The linearity of the activity res...

متن کاملSurvey of the performance of commercial dose calibrators for measurement of ¹²³I activity.
UNLABELLED The accuracy with which (123)I activity is measured by a dose calibrator depends on the composition and geometry of the source. The present study assessed the variability of current commercial dose calibrators in assaying liquid (123)I samples. METHODS A calibration procedure for (123)I measurement was performed on 177 dose calibrators (11 manufacturers) at 138 sites in North Ameri...
