TY - JOUR T1 - Quality Control Testing of Dose Calibrators JF - Journal of Nuclear Medicine Technology JO - J. Nucl. Med. Technol. SP - 124 LP - 128 VL - 24 IS - 2 AU - Robert Y.L.

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 99mTc 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 99Mo contamination are examined. ER -
