Abstract: Secondary high-energy neutrons are produced when high-energy particles (of several GeV) interact with matter as it is the case for cosmic radiation impinging on the Earth’s atmosphere, during ion-beam therapy or on shielding at high-energy particle accelerators. Especially, after traversing a large amount of matter, the residual neutron energy spectrum exhibits two energy regions which mainly contribute to the total ambient dose equivalent: around 1 MeV (evaporation peak) and around 100 MeV. Particle detectors...
Visions for Radiation Dosimetry over the Next Two Decades – Strategic Research Agenda of the European Radiation Dosimetry GroupWerner Rühm, Elena Fantuzzi, Roger Harrison, Helmut Schuhmacher, Filip Vanhavere, Joao Alves, Jean-Francois Bottolier-Depois, Paola Fattibene, Željka Knežević, María Antonia Lopez, Sabine Mayer, Saveta Miljanić, Stefan Neumaier, Pawel Olko, Hannes Stadtmann, Rick Tanner & Clemens Woda
Abstract: The European Radiation Dosimetry Group (EURADOS) comprises a self-sustainable network of more than 60 European institutions such as reference and research laboratories, dosimetry services and companies, as well as more than 300 scientists active in the field of radiation dosimetry. The aim of the network is to promote research and development and European cooperation in the field of dosimetry of ionizing radiation and its implementation in routine practice, in order to contribute to compatibility...
Challenges in Micro-and Nanodosimetry for Ion Beam Cancer Therapy (MIND-IBCT) - Report on an International Workshop co-organized by EURADOSThorsten Schneider, Heidi Nettelbeck & Hans Rabus
Abstract: Ion beam therapy offers the possibility of excellent dose localization for treatment of malignant tumours, minimizing radiation damage in normal tissue, while maximizing cell-killing within the tumour. However, the full potential of such therapy can only be realised by better understanding of the physical, chemical and biological mechanisms. The workshop MiND-IBCT (Micro- and Nano-Dosimetry for Ion Beam Cancer Therapy) was focussed on challenges encountered in the application of micro- and nanodosimetry for ion beam...
Abstract: The COUNCIL DIRECTIVE 2013/59/EURATOM of 5 December 2013 laying down basic safety standards for protection against the dangers arising from exposure to ionising radiation addresses radon at workplaces and at homes: Radon is directly addressed in the Basic Safety Standards Directive through Article 54 concerning workplace radon levels, Article 74 concerning indoor radon levels, and Article 103 for the national action plan. The new directive brings significant changes, with respect to the former Directive...
Abstract: EURADOS has carried out a number of different intercomparison exercises for personal dosemeters in the past that qualify as proficiency tests for different dosimetry systems and radiation types including one previous neutron personal dosemeter intercomparison (IC2012n). Neutron intercomparisons are especially complicated to design because of the limited availability of reference fields and the costs associated with the exposures. IC2017n was the second EURADOS organized intercomparison exercise for neutron personal dosemeters. It was an important...
Abstract: High-energy neutrons are the dominant component of the prompt radiation field present outside the shielding of high-energy accelerators, and are a significant component of the cosmic radiation fields in aircraft and in spacecraft. In radiotherapy using high-energy medical accelerators, high-energy neutrons are a secondary component of the fields in the beam delivery system and in the patient’s body. The range of neutron energies in these fields extends from thermal energies to several GeV, and...
Abstract: The aim of this report is to compare the doses and dose rates calculatedby various codes assessing radiation exposure of aircraft crew due to cosmic radiation. Some of the codes are used routinely for radiation protection purposes while others are purely for scientific use. The calculations were done using a set of representative, real flight routes around the globe. The results are presented in an anonymous way. This comparison is of major importance since...
Abstract: EURADOS, within the work performed by Working Group 2 -Harmonization of Individual Monitoring in Europe, has started a self-sustained programme of regular intercomparisons and has successfully executed three intercomparisons for whole body photon dosemeters (IC2008, IC2010, IC2012) and one intercomparison for extremity dosemeters for photon and beta fields (IC2009). In 2012, the EURADOS intercomparison IC2012n was launched for personal neutron dosemeters routinely used to measure personal dose equivalent, Hp(10), in individual monitoring. No systems...
A mechanism called steady-state microbunching (SSMB) has been proposed to generate high-repetition, high-power coherent radiation in an electron storage ring. Such a novel phton source will provide unprecedented opportunities for accelerator photon science and technological applications. In this paper, we report the first demonstration of the mechanism of SSMB. This demonstration represents a crucial step towards the implementation of an SSMB-based high-repetition, high-power photon source.
A model validation scheme for Monte Carlo simulationsof a medical linear accelerator: geometrical description and dosimetric dataused in the “Linac Action”Barbara Caccia, Valentin Blidéanu, Maïwenn Le Roy, Hans Rabus & Rick Tanner
Abstract: Radiation therapy has become more complex over the past few years with the use of new techniques like IMRT (Intensity Modulated Radiation Therapy) and stereotactic treatments. Moreover, optimisation of the radiotherapeutic treatment has become a critical point in the overall planning and delivery process due to the trend in dose-escalation with these new techniques and the associated risk for damage to healthy tissue. Typically, in techniques such as IMRT the dose distribution includes steep...
Introduction: On June 30th, 2016, the “First EURADOS Stakeholder Workshop” was held at the Helmholtz Center Munich (HMGU) in Neuherberg, Germany. The workshop was jointly organized by the HMGU and the EURADOS Office in conjunction with the 57thEURADOS Council meeting, which took place on June 29thand July 1st, also at the HMGU. In the frame of the “European Joint Programme for the Integration of Radiation Protection Research”, the CONCERT project funded by the European Commission...

Introduction: The European Radiation Dosimetry Group (EURADOS) comprises a self-sustainable network of more than 70 European institutions and about 600 scientists active in the field of radiation dosimetry. It was founded in 1981, and was registered in Germany as an “e.V.” (registered society) in 2008. The aim of the network is to promote research and development and European cooperation in the field of dosimetry of ionising radiation. For this, EURADOS has established Working Groups (WGs)...
