(x-ray fluorescence)], in Environmental radioactivity [Alpha and Gamma spectroscopic measurements in environmental and biological samples, in-situ measurements, total a/b measurements], in in-vivo measurements for internal dosimetry [whole body counting & thyroid uptake of the workers and members of the public] and in nuclear and radiological emergency and response. He participates in the following international group of experts’ teams: (1)determination of clearance levels in commodities (International Atomic Energy Commission) (2) post conflict environmental assessment of DU in Serbia (United Nations Environmental Protection Agency) and in Bosnia and Herzegovina (United Nations Environmental Protection Agency) (3) EURATOM Article 31 and Articles 35-36 (4) EURADOS Working Group 3. He is also the national representative in various international organizations in the field of radiation protection of the workers, the environment and the public. Dr Potiriadis has participated in various research projects funded by EU, NATO, and the Greek government. He is (co)author of 40 publications in referred journals. His current research work is in the field of dose determination from charged particles considering their species. He has played a key role in the development of the MIDAS device and in the analysis of the neutron measurements with it. He is the deputy technical responsible of the “Comprehensive radiation monitor package for Lunar mission” project and he is leading the Scintillator/SiPM effort.

Dr CHRISTOS PAPADIMITROPOULOS

• Dr. Papadimitropoulos is an associate researcher with the NKUA. He obtained a degree in Physics, University of Patras, Greece, and a MSc in Electronics and Telecommunications, Faculties of Physics and Informatics (joined program), University of Athens, Greece. In 2008, he received his Ph.D. in Data Acquisition for the CMS experiment (LHC), Physics Department of the University of Athens, Greece. During his PhD dissertation, Christos developed a simulation tool for studying the functional behavior of the Data Acquisition (DAQ) system for the CMS experiment at the Large Hadron Collider, CERN. This tool estimated the intrinsic parameters for optimum performance under intensive operation conditions and at an aggregate throughput of 100GB/s. The validity of the model and the accuracy of the results were confirmed either via Queuing Theory models or via experimental results on smaller-scale DAQ prototypes. After his PhD, Dr Papadimitropoulos was engaged in the development of a data acquisition system for pixelated CdTe radiation detectors and in the use of the images acquired by them for coded aperture imaging. He has been working for the simulation of the MIDAS detector using GEANT4 and for the experimental tests of the device in neutron beams and with gamma ray and neutron sources. Christos has published 13 papers in peer-reviewed journals. He is leading the beam test measurements and analysis for the “Comprehensive radiation monitor package for Lunar mission” project.

Dr KONSTANTINOS KARAFASOULIS

• Dr Karafasoulis is an associate researcher with the NKUA. He works also at the Hellenic Army Academy as Laboratory Special Teaching Staff He holds a BSc in Physics from the Aristotle University of Thessaloniki and a Ph.D in High Energy Physics (DELPHI/CERN) experiment from the National Technical University of Athens. Konstantinos has 20 years working experience in the fields of radiation detector simulation, data acquisition systems and data analysis techniques. He has participated in the DELPHI and CMS experiments at CERN with the Demokritos/Greece and INFN/ Italy teams and he has been involved in various European and National funded R&D projects for the simulation and development of radiation detectors, data acquisition systems and novel data analysis techniques (e.g. NATO SENERA, FP7-COCAE, EPAN, PYTHAGORAS, PENED, ESA-C14240). He is involved in the detailed simulation with GEANT4 of the MIDAS device and in the development of reconstruction algorithms for deducing the energy and the identity of particles crossing the device based on the energy depositions of the particles in the MAPS. He is leading the GEANT4 simulations effort in the “Comprehensive radiation monitor package for Lunar mission” project.
