The Ionizing Radiation section of our laboratory has been recently evaluated by the Greek Atomic Energy Commission, which certified its compliance with the National radiation protection legislation and renewed its license until the year 2026. Our laboratory is equipped with a Co-60 small sample irradiation facility, a HPGe and two NaI(Tl) gamma spectroscopy systems, a Thermoluminescence Dosimetry system, several radiation detectors and numerous radiation sources for research and educational purposes.
