The Active personal dosemeter (APD) developed by Çekmece Nuclear Research and Training Center/Nuclear Electronic Laboratory (ÇNRTC/NEL) was calibrated at the reference radiation quality (137Cs). The performance tests were carried out with 137Cs, 60Co and X-ray beam qualities in compliance with the standards of International Organization for Standardization ISO4037-1,3 and The International Electrotechnical Commission, IEC61526:2010. Response of the personal dose equivalent was observed to be within the range from -7.6% to +4.2%. The dose equivalent rates were observed with the maximum deviation -26.8% for 0.1 mSv h-1 and within the range from -2.3% to +10.1% for dose rates over 0.5 mSv h-1. It is found that the APDs have lower readings up to 50% for 33 keV photons and perform a distribution in the acceptable limits for over 33 keV. Angular dependence was tested at 0°, ±30° and ±60° in orthogonal plane and the angular dependence of the APDs is within acceptable limits except N40.
