Digital graphical user interface as a facilitator for the calibration of radiation monitoring instruments according to ISO 4037:2019 at the national secondary standard dosimetry laboratory of morocco

Abstract

current legislation requires the inspection and calibration of operational survey radiation monitoring instruments used in nuclear medicine and radiotherapy departments as well as in any field that uses ionizing radiation sources. As a result, Morocco's national secondary standard dosimetry laboratory provides reliable calibration results with high accuracy while adhering to national and international radiation protection standards and covering the various measurement ranges, using the attenuators offered by the automated Gamma G10 irradiator or the validated beam qualities produced by the X-ray irradiator type X80-320kV as required. The measurements’ reliability was demonstrated by participation in a comparison program launched by the International Atomic Energy Agency (IAEA).This work aims to develop a digital graphical user interface designed for the calibration of measuring instruments in radiation protection through the programming language Python, which serves to facilitate the establishment of all operations and calculations related to the determination of calibration factors and measurement uncertainties according to the ISO 4037 standard in a minimum time that allows to process several instruments during the day with high accuracy, while minimizing the sources of errors, this interface allows the recording of calculations as well as the establishment and electronic archiving of the calibration certificate in pdf format ported from PHP FPDF.
