Cephalonia Island, located in western Greece, is characterized by complex geological and tectonic conditions associated with the active Cephalonia Transform Fault Zone (CTFZ), and lies at the boundary between the Paxos (Pre-Apulian) Zone and the Ionian Zone (Lekkas, 1996). The Paxos Zone is mainly characterized by relatively undeformed carbonate platform formations consisting predominantly of...

Occupational radiation exposure (ORE) assessments are initiated from the earliest stages of nuclear facility design in order to identify high-dose operations, support dose optimization, and guide the selection of appropriate design solutions. Maintenance activities on plant systems may contribute significantly to both individual and collective doses to personnel. Consequently, ORE evaluations...

Since 2023 radon exhalation measurements were carried out by our research team in northerneastern Greece. Measured values vary from 3.62 to 432 Bq•m⁻²•h⁻¹ (Fig. 1). Exhalation rates were measured by using a diffusion accumulator [1]. While the importance of lithology on radon exhalation has been recognized [2], lithology itself does not solely govern radon exhalation. The role of structural...

Deep marine basin sediments serve as repositories of information on physicochemical processes and the transport behavior of tracers in aquatic environments. The vertical profiles of radionuclides in the water column combined with radiochronological models in the seabed cores can provide new information in terms of geological and radiological processes. The activity concentration data of four...

The understanding and protection of human’s due to the consequences of nuclear incidences has become an increasingly important scientific and technological challenge. This research focuses on quantification methods of underwater gamma-ray spectrometers to identify radioactive objects in aquatic systems. The work addresses the critical need for rapid, accurate, and non-invasive monitoring...

Accurate dosimetry in radiobiological experiments using proton beams requires high resolution, energy-dependent characterization of the Bragg peak, which is essential for understanding variations in Linear Energy Transfer (LET) and the corresponding radiobiological effects along the proton track. Proton beam dosimetry is typically performed using parallel-plate ionization chambers with small...

Single-photon emission computed tomography myocardial perfusion imaging is widely used for the non-invasive assessment of coronary artery disease. Although deep learning has shown promise for automated SPECT myocardial perfusion interpretation, most previous approaches have focused on single-tracer datasets and have not explicitly considered tracer-dependent variability. This study aimed to...

The radiological characterization of activated nuclear reactor components, resulting from neutron-induced reactions, which frequently also exhibit surface contamination, is essential for decision-making regarding their management during decommissioning. Prior to the dismantling and segmentation of reactor components, the selection of an appropriate cutting technology, aimed at minimizing of...

Dr Nikos Salpadimos (Greek Atomic Energy Commission)06/06/2026, 11:30Talk
The Greek Atomic Energy Commission (EEAE), as the national regulatory authority, is responsible for ensuring radiological protection and nuclear safety. To this end, EEAE focuses on the assessment of nuclear or radiological emergencies, which may entail radiological risk for the country. In this context, a series of hypothetical nuclear detonation tests were simulated and studied, using...
