Calibration of current integrators used with ionization chambers

Abstract

© 2012 RAD Conference Proceedings. All rights reserved. Verification of ionizing radiation detectors is a legal requirement in Serbia. Our Laboratory for metrology is accredited in terms of SRPS ISO/IEC 17025 for verification of the ionizing radiation detector readers as are electrometers and current integrators. Laboratory performs calibration of current integrators in range between 100 fA and 100 mA with expanded uncertainty better than 0.05 % (k=2). As the main part of each calibration procedure is uncertainty estimation and design of uncertainty budget. Therefore, we decided to give results and elements of uncertainty budget obtined during calibration procedure of current integrator type ND 2000 used with standard ionization chambers.
