Radiation Dose and Risk in the Radiological Investigation of Suspected Non‐Accidental Injury (NAI)

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S92-S100, April 2026.
This study is a retrospective analysis of 362 skeletal surveys performed over a 5‐year period for children under 5 years of age for suspected non‐accidental injury. We present effective dose data and the associated risks of radiation exposure for initial and follow‐up examinations.

Characterization of a new radiochromic film (LD-V1) using mammographic beam qualities

Zeitschrift für Medizinische Physik
Purpose: Radiochromic film (RCF) is a detector that can obtain a two-dimensional dose distribution with high resolution; it is widely used in medical and industrial fields. Several types of RCFs exist based on their application.

Important comments on KERMA factors and DPA cross-section data in ACE files of JENDL-4.0, JEFF-3.2 and ENDF/B-VII.1

EPJ Web of Conferences, 2017
We have studied reasons of differences of KERMA factors and DPA cross-section data among nuclear data libraries. Here the KERMA factors and DPA cross-section data included in the official ACE files of JENDL-4.0, ENDF/B-VII.1 and JEFF-3.2 are examined in ...

MTS-6 detectors calibration by using 239Pu-Be neutron source

Medycyna Pracy, 2017
Background: Thermoluminescent detectors, type MTS-6, containing isotope 6Li (lithium) are sensitive in the range of thermal neutron energy; the 239Pu-Be (plutonium-and-beryllium) source emits neutrons in the energy range from 1 to 11 MeV. These seemingly

Proposed Diagnostic Reference Levels for Frequently Performed Paediatric Radiographic Examinations

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S9-S25, April 2026.
Paediatric diagnostic reference levels (DRLs) are weight‐stratified dose levels for typical medical imaging examinations for broadly defined types of equipment. The 75th percentiles of the FRLs across the nine X‐ray units from five centres in Australia were calculated as the proposed Local DRLs (LDRLs).

Your C‐Arm May Be Dose Optimised but Is Your Surgical Procedure? The Evaluation and Dose Optimisation of Positioning Aids Used in Paediatric Image Guided Surgery

Journal of Medical Radiation Sciences, Volume 73, Issue S2, Page S26-S34, April 2026.
This study objectively evaluated the impact of positioning aids on radiation dose and image quality (IQ) in paediatric image guided surgery (IGS) and the potential for dose optimised imaging via the choice of positioning aid type selected for clinical use.

Safety and Efficacy of Pulsed Field Ablation for Atrial Fibrillation in Older Patients: An Observational Study at a Large Tertiary Centre in Australia

Journal of Arrhythmia, Volume 42, Issue 2, April 2026.
In this retrospective observational study, pulsed field ablation using a specific pentaspline catheter showed comparable procedural and clinical outcomes between older (aged ≥ 75 years) and younger patients (aged < 75 years). However, judicious patient selection is still warranted and randomized trial data are needed to confirm these findings. ABSTRACT
