title: A PRACTICAL APPROACH TO PERFORM THE ISOTROPY TEST FOR EXTREMITY DOSEMETERS.
abstract: The requirements for determining extremity dosemeter performance have evolved over the past decade. In 2010, the Spanish Nuclear Safety Council (CSN) adopted a national protocol with performance requirements based on ISO 12794. Because of the lack of symmetry of ISO 4037-3 calibration phantoms, the isotropy test set up in the sagittal plane presented several challenges both for individual monitoring services and for calibration labs. This article proposes and validates a practical approach to reduce the number of irradiations. Results show that wrist and ring dosemeters in this study meet the ISO 12794 requirements for the isotropy test. However, additional studies would be needed to verify the newer IEC 62387 Standard.
