Abstract
Since radionuclide calibrators are used in nuclear medicine for the determination of the activity of radiopharmaceuticals administered to patients, it is important to ensure their long-term accuracy. Results of the checks performed in the Czech Republic during the year 2002 are given, together with a short overview of previous years. For the CMI 4pigamma ionization chamber, against which all the calibrators are checked, we calculated the response function and basic characteristics by a Monte Carlo method, using the MCNP4C code.
