11. Improvement of Characterization of Compressible Radioactive Waste at the LVR-15 Research Reactor Facility

Jakub Beinstein (Centrum výzkumu Řež s.r.o.)

6/9/26, 2:00 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Regulatory requirements set by the radioactive waste repository operator and the waste processor necessitate verifying that waste intended for disposal does not contain materials exempt from regulation under applicable legislation or radionuclides with only short half lives. At the LVR 15 research reactor facility, the dominant contaminant in compressible waste is activated water from the...

24. Active and passive area dosimetry of photon fields surrounding the experimental bunkers of ELI-NP

Cosmin-Marius Branzoi (”Horia Hulubei” National Institute for Research and Development in Physics and Nuclear Engineering (IFIN-HH), Extreme Light Infrastructure - Nuclear Physics (ELI-NP), 30 Reactorului Street, Magurele, 077125, Romania; Faculty of Power Engineering, National University of Science and Technology ”Politehnica” of Bucharest, Splaiul Independentei 313, Bucharest, 060042, Romania)

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Extreme Light Infrastructure - Nuclear Physics (ELI-NP) represents a world-class, state-of-the-art research infrastructure specifically designed to push the boundaries of photonuclear physics. The facility is equipped with advanced systems for the generation of high-energy particle fields, complemented by sophisticated monitoring instrumentation tailored for the precise detection and...

46. EHEAD: Ultra High Dose Rate Dosimetry

Ouissal Khattabi (CEA Saclay)

6/9/26, 2:30 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Flash therapy is a radiation therapy technique that aims to take advantage of the potentially greater effectiveness of treatment using electrons with high absorbed dose rates, approximately 1 MGy/s. Several LINACs are currently being installed and tested to demonstrate the clinical benefits of this irradiation method. Laser acceleration processes promise even higher rates, about 100 GGy/s,...

48. Characterization of neutron fields around refurbishment waste at Bruce Power and OPG using neutron spectrometry and Monte Carlo modelling

Jovica Atanackovic (Ontario Power Generation)

6/9/26, 2:45 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Using neutron spectrometry, we characterized the neutron energy spectra coming from irradiated components of a refurbished CANDU reactor. The measured neutron energy spectra were from refurbishment waste, from calandria tubes (CTs) and pressure tubes (PTs). The measurements were conducted using a Nested Neutron Spectrometer (NNS), manufactured by Canadian company DETEC Inc. They were...

104. Methodology for Radiological Emergency Preparedness at CIEMAT for In Vivo Wound Monitoring of Internal Contamination: Validation within the EURADOS/ARADOS Intercomparison Framework

JUAN FRANCISCO NAVARRO AMARO (CIEMAT (Centro de Investigaciones Energéticas, Medioambientales y Tecnológicas)

6/9/26, 3:00 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

The harmonisation of in vivo wound monitoring techniques is essential for improving emergency response and ensuring the comparability of results among laboratories. This work presents the methodology applied and the results obtained by the CIEMAT Whole Body Counter (WBC) Laboratory during its participation in the EURADOS/ARADOS intercalibration and intercomparison exercise on wound monitoring....

111. Design and validation of a modular Cf-252—based simulated workplace field using a concentric-cube moderator for spent-fuel applications

Sita Gandes Pinasti (SCK CEN / ULB)

6/9/26, 3:15 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Accurate neutron personnel monitoring in nuclear installations requires calibration fields that reproduce workplace spectral characteristics. Existing simulated neutron workplace fields (SWF) are largely optimized for nuclear reactor conditions and offer limited flexibility for representing spectra relevant to spent-fuel handling. This work presents the design and initial validation of a...

126. Beam loss assessment of 3 GeV linear accelerator in NanoTerasu

Akihiro Takeuchi (QST)

6/11/26, 2:45 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Introduction
A fourth-generation synchrotron light source: NanoTerasu consists of a 3-GeV linear accelerator (linac) and a storage ring equipped with insertion devices. Since the stored beam current in the storage ring decays due to beam lifetime effects caused by residual gas scattering and Touschek scattering, electrons are continuously injected from the linac in top-up mode to maintain...

137. Dosimetry characterization of a mobile medium-energy electron beam facility dedicated to treating industrial wastewater

Carmen Bueno (IPEN-CNEN)

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

The dosimetry characterization of a mobile electron-beam (EB) facility, tailored to treat industrial wastewater on site, is reported in this work. The accelerator operates at electron-beam energies of 500-700 keV and currents of 1-28 mA. The beam is magnetically scanned at 200 Hz to cover approximately 60 cm of a continuous water flow with a depth of 5 mm. Several well-established dosimeters...

179. ICIDOSE#2 Intercomparison: Overview and General Conclusions

Tamás Pázmándi, Zsófia Rékasi

6/11/26, 3:15 PM

Dosimetry and radiation protection in nuclear installations and at accelerators

Oral Presentation

Internal dose assessment involves complex analytical procedures and expert judgement, including the selection of appropriate biokinetic models, evaluation of measurement uncertainties, and the application of case-specific assumptions. Consequently, identical measurement data may lead to different intake and dose estimates when assessed by different laboratories. Intercomparison exercises...
