Abstract
The Radioisotope Centre (RC) has organized for the first time in Polish hospitals a comparison of activity measurements of 99Tcm and 131I. From the 58 Polish hospitals invited, 37 participated in the comparison. Each participant got about 4 mL of 99Tcm eluate and two 131I capsules, low- and high-activity. Sources were standardized in the RC before dispatch using a 4π ionization chamber calibrated by standard solutions. Participants used their own radionuclide calibrators. The measurement results were evaluated using the En criterion and the z′-score. From all 118 measurement results received from participants, 75 results (64%) lay within ±5% of the RC value, and 99 results (84%) lay within ±10.0%.
