The International Atomic Energy Agency (IAEA), jointly with the World Health Organization (WHO), has operated a postal dosimetry audit program for radiotherapy centers worldwide since 1969. In 2017 IAEA introduced new methodology based on radiophotoluminescent (RPLD) these audits. detection system consists of phosphate glass dosimeter inserted in plastic capsule that is kept measuring position ...

At SSDLs the recommended detector for the calibration of all brachytherapy photon sources, as well as for the calibration of intravascular beta sources, is an appropriately calibrated well type chamber. For SSDLs the preferred method for traceability in the source calibrations is to have the well type chamber calibrated against the primary standard at the PSDL. However, due to practical reasons...

The paper presents some recent results of the Radionuclide Metrology Laboratory (RML) from IFIN-HH, in the assurance of quality in radioactivity measurements for nuclear medicine. Three aspects are treated: (i) Participation of the RML in the frame of the IAEA Coordinated Research Program (CRP), E 2.10.05; (ii) Improvement of the secondary standard, based on a CENTRONIC IG12/20A ionization cham...

The Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWGNPPCI) of IAEA has been active in providing guidance for the I&C field in the form of technical documents and reports. This year the writing of a new TECDOC to address the challenges in the implementing and licensing digital I&C in nuclear power plants was initiated. This paper reports on discussions within this ...
