Dosimetry for second cancer risk estimation in radiotherapy:measurements in water phantoms

R. M. Harrison, A. Di Fulvio, J. M. Bordy, S. Miljanić, L. Stolarczyk & Ž. Knežević
Abstract: This report describes dosimetry techniques used by EURADOS Working Group 9 (Radiation Dosimetry in Radiotherapy) to measure out-of -field doses for use in radiotherapy. Several passive dosimeter types were used, based on the physical principles of thermoluminescence (TLD), optically simulated luminescence (OSL) and radiophotoluminescence (RPL), in addition to an ionization chamber used as a reference standard. Superheated drop, bubble damage and track etch detectors were used specifically for neutron measurements. In this report, doses...

Challenges in Micro-and Nanodosimetry for Ion Beam Cancer Therapy (MIND-IBCT) - Report on an International Workshop co-organized by EURADOS

Thorsten 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...

Uncertainties in internal dose assessment: Lifetime dose assessment for three example workers occupationally exposed to uranium - Analysing the intercomparison results

Estelle Davesne, Richard Bull, Jeri Anderson, Derek Bingham, Alan Birchall, Carlo Maria Castellani, Cécile Challeton-de Vathaire, M. L. Fernandez, Martina Froning, A. Giomi, Anne Laure Lebacq, Jakub Ośko, Inés Gomez Parada, Anna Pántya, A. G. Rojas, Ana Rojo, Masa Takahashi, Kotaro Tani & Eric Blanchardon
Abstract: Recently, several epidemiological studies were interested in identifying potential health effects of incorporated radionuclides. To achieve this work, exposure of individuals was quantified in order to be compared with health status. In order to quantify the exposure of workers, the measurement of retained or excreted activity also called bioassay, must be interpreted in terms of dose. The data available for dose reconstruction are mostly bioassay analyses (mostly urine) carried out to verify the absence...

InterComparison on Internal DOSE Assessment – ICIDOSE 2017 Analysing the intercomparison results

Carlo Maria Castellani, Andor Andrasi, Augusto Giussani, Tamas Pázmándi, Gareth Roberts & George Etherington
Abstract: Internal dose assessment often requires complex processes and judgements. “Technical Recommendations for Monitoring Individuals for Occupational Intakes of Radionuclides” (TECHREC) was developed during 2014 to 2016 as a tool for internal dosimetrists. The TECHREC recommendations have been publishedin the Radiation Protection document series of the European Commission as document RP188 (EC 2018). They aim to encourage harmonisation, to present a complete account of the principles of individual monitoring and internal dosimetry, and to provide...

Data from: Opposing effects of allogrooming on disease transmission in ant societies

Fabian J. Theis, Line V. Ugelvig, Carsten Marr & Sylvia Cremer
To prevent epidemics, insect societies have evolved collective disease defences that are highly effective at curing exposed individuals and limiting disease transmission to healthy group members. Grooming is an important sanitary behaviour—either performed towards oneself (self-grooming) or towards others (allogrooming)—to remove infectious agents from the body surface of exposed individuals, but at the risk of disease contraction by the groomer. We use garden ants (Lasius neglectus) and the fungal pathogen Metarhizium as a model system...

In addition, three ICs with different scopes were carried out, two for extremity dosemeters in photon and beta fields (IC2009ext, IC2015ext) and one for whole-body dosemeters...

Irradiations at the High-Energy Neutron Facility at iThemba LABS

A. Buffler, G. Reitz, S. Röttger, F. D. Smit & F. Wissmann
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...

Cristobal Uauy, Jemima Brinton, Ricardo Ramirez-Gonzalez, James Simmonds, Luzie Wingen, Simon Orford, Simon Griffiths, Georg Haberer, Manuel Spannagl, Sean Walkowiak & Curtis Pozniak
Crop productivity must increase at unprecedented rates to meet the needs of the growing worldwide population. Exploiting natural variation for the genetic improvement of crops plays a central role in increasing productivity. Although current genomic technologies can be used for high-throughput identification of genetic variation, methods for efficiently exploiting this genetic potential in a targeted, systematic manner are lacking. Here, we developed a haplotype-based approach to identify genetic diversity for crop improvement using genome assemblies...

Judy Simon, Robert Reuter, Olga Ferlian, Mika Tarkka, Nico Eisenhauer & Karin Pritsch
A field study was conducted to evaluate the effects of associated mycorrhization type on tree-tree interactions using the framework of the MyDiv tree diversity experiment established at the Bad Lauchstädt Experimental Research Station of the Helmholtz Centre for Environmental Research (UFZ) (Saxony-Anhalt, Germany). Inorganic and organic net N uptake capacity was quantified in fine roots of AM (i.e. Acer pseudoplatanus L., Fraxinus excelsior L., and Prunus avium L.) as well as EM associated tree species...

LSFM-image z-stack of an optically cleared porcine adipose tissue sample

Andreas Blutke
In translational obesity research, objective assessment of adipocyte sizes and numbers is essential to characterize histomorphological alterations linked to obesity, and to evaluate the efficacies of experimental medicinal or dietetic interventions. Design-based quantitative stereological techniques based on the analysis of 2D-histological sections provide unbiased estimates of relevant 3D-parameters of adipocyte morphology, but often involve complex and time-consuming tissue processing and analysis steps. Here we report the application of direct 3D light sheet fluorescence microscopy (LSFM)...

IDEAS Guidelines (Version 2) for the Estimation of Committed Doses from Incorporation Monitoring Data

C.M. Castellani, J.W. Marsh, C. Hurtgen, E. Blanchardon, P. Berard, A. Giussani & M.A. Lopez
ABstract: Doses from intakes of radionuclides cannot be measured but must be assessed from monitoringdata, such as whole body, urine or faecaldata. Such assessments require applicationofbiokinetic and dosimetric models, and the assessor may well have to make assumptions about factors such as the pattern of intake and properties of the material. Intercomparison exercises (Doerfel 2000) have shown a wide range in doses that can be obtained from the same data set as a result of...

High-energy quasi-monoenergetic neutron fields: existing facilities and future needs

S. Pomp, D.T. Bartlett, S. Mayer, G. Reitz, S. Röttger, M. Silari, F.D. Smit, H. Vincke & H. Yasuda
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...

ORAMED: Optimization of Radiation Protection of Medical Staff

F. Vanhavere, E. Carinou, G. Gualdrini, I. Clairand, M. Sans Merce, M. Ginjaume, D. Nikodemova, J. Jankowski, J.-M. Bordy, A. Rimpler, S. Wach, P. Martin, L. Struelens, S. Krim, C. Koukorava, P. Ferrari, F. Mariotti, E. Fantuzzi, L. Donadille, C. Itié, N. Ruiz, A. Carnicer, M. Fulop, J. Domienik & M. Brodecki
Abstract: The medical staff performing interventional cardiology and radiology (IC/IR) procedures stand close to the patient and thus close to the primary radiation beam. Although they wear a lead apron and thyroid collar, their hands, legs and eyes are not protected. Therefore, these parts could receive significantly high doses. Moreover, thedose ranges for the same kind of procedures vary a lot, as many factors affect extremity and eye lens doses. Additionally, there is evidence that...
