27. AI-Enhanced Monte Carlo Dosimetry for Radiotherapy Dose Optimization in Complex Cancer Cases.

Melika Karimloosayah (Tabriz University of Medical Sciences, Department of Medical Physics, PhD Student of Medical Physics)

6/10/26, 11:00 AM

Computational methods and modelling in dosimetry

Oral Presentation

Achieving an optimal balance between effective tumor control and healthy tissue protection remains a key challenge in radiotherapy. Conventional treatment planning methods are often limited to simplified mathematical models and cannot fully account for patients’ anatomical complexities and dynamic tissue responses.

In this study, we present an innovative approach integrating Monte Carlo...

38. Integrated Geant4–TCAD Simulation of Radiation Effects in RadFETs Toward the Development of Low-Cost Dosimetry Solutions

Sabri MANAÏ (HE2B ISIB)

6/10/26, 11:15 AM

Computational methods and modelling in dosimetry

Oral Presentation

In radiation protection, accurately assessing individual exposure relies on operational quantities such as $H_p(10)$ and $H_p(3)$, which serve as measurable surrogates for the effective dose. However, designing compact electronic dosimeters that remain accurate across a wide range of photon energies and incidence angles is a significant challenge, especially when prioritizing low-cost and...

63. Modelling radiation field in decommissioning: from measurements survey to the ML-based dose interpolation

Federica Roberto (SCK CEN)

6/10/26, 11:30 AM

Computational methods and modelling in dosimetry

Oral Presentation

To enable planning and dose assessment in Decommissioning and Dismantling (D&D) environments, we are developing a computational pipeline, based on Monte Carlo (MC) methods, through the application of Machine Learning (ML) techniques. The characterization of radiation fields is the first fundamental step in creating such pipeline.

In this work, we present a case study that demonstrates the...

67. Deconvolution and artificial intelligence in the estimation of exposure date in thermoluminescent personal dosimetry based on experiments at the Institute of Applied Nuclear Physics, Albania

Ervis Gega (Institute of Applied Nuclear Physics, University of Tirana)

6/10/26, 11:45 AM

Computational methods and modelling in dosimetry

Oral Presentation

This study brings an advanced experimental and computational investigation on the fading of thermoluminescent dosimeter signals to arrive at analytical rules and trained neural networks for the estimation of the potential accidental exposure of occupationally exposed workers. A systematic radiation measurement protocol was implemented, where personal dosimeters were exposed twice a week (20...

85. Polychromatic Quantitative Absorption Tomography for Multi-Component Samples with Cross-Contamination Artifact Correction

Dr Chanh Q Tran (Department of Mathematical and Physical Sciences, La Trobe University, Victoria 3086, Australia)

6/10/26, 12:00 PM

Computational methods and modelling in dosimetry

Oral Presentation

Beam-hardening and material cross-contamination remain significant challenges in quantitative computed tomography of multi-component samples acquired using polychromatic X-ray sources. For medical applications, the limited precision and portability of CT scan results often necessitate multiple diagnostic scans, leading to unnecessary radiation exposure for patients.
In this work, a...

190. CFPD-Informed Reduced-Order and Artificial Intelligence Framework for Mechanistic Inhalation Dosimetry Across Emergency Response and Population Applications

Shaheen Dewji (Georgia Institute of Technology)

6/11/26, 11:00 AM

Computational methods and modelling in dosimetry

Oral Presentation

Mechanistic inhalation dosimetry for airborne radionuclides requires spatially resolved particle deposition profiles within anatomically realistic respiratory tract geometries. Compartmental approaches, including those of the International Commission on Radiological Protection (ICRP), assume regionally uniform deposition and population-averaged morphometry, limiting resolution for emergency...

201. Gamma Spectrometry: Pulse‑Height Detector Implementation in the Serpent 2 Monte Carlo Code

Ana Jambrina (VTT Technical Research Centre of Finland Ltd)

6/11/26, 11:15 AM

Computational methods and modelling in dosimetry

Oral Presentation

Pulse‑height detectors are a standard instrument in Monte Carlo radiation‑transport simulations for reproducing high‑fidelity photon‑interaction spectra essential to gamma‑spectrometry analysis. Their use requires reconstructing the complete sequence of energy‑deposition events arising from all photon and secondary‑particle interactions within the detector medium.

This work presents a...

100. Enhancement of L and M characteristic X-rays due to Compton ionization after excitation with a polarized source

Prof. Jorge Eduardo FERNANDEZ (Alma Mater Studiorum University of Bologna)

6/11/26, 11:30 AM

Computational methods and modelling in dosimetry

Oral Presentation

The Compton effect is a well-known scattering process. When the incoming photon energy is sufficiently high, it represents a possible ionization mechanism for the inner shells of atoms. The resulting vacancies can be filled through spontaneous atomic relaxation, a process analogous to photoabsorption.
A preliminary description based on the Waller–Hartree approximation [1] showed that, for K...
