Performance evaluation of the reference system for calibration of ipen activimeters

reliability of 90% recommended by CNEN standard. All tests performed were satisfactory, not exceeding the recommended limit. In Table 2, it is possible to observe the results of accuracy test, that is the percentage deviation between mean of activity measured (10 measures) and the standard source activity with the application of the decay correction factor. TABLE 2: Results obtained for the accuracy test with reference sources in both activimeters.

They consist of two parts: the console in which the electrometer is situated, and the ionization chamber, both by Capintec, as presented in Figure 1. The reference system is a secondary standard, model NPL-CRC® radionuclide calibrator, serial number 111113, manufactured by Southern Scientific plc, with traceability to National Physical Laboratory (NPL). The system to be used as work standard is a model CRC®15BT, serial number 180020, calibrated by Accredited Dosimetry Calibration Laboratory of Medical Radiation Research Center – University of Wisconsin, with traceability to National Institute of Standard and…
