Is it possible to reduce radiation exposure during transcatheter atrial septal defect closure in children?

Türk Kardiyoloji Derneği Arşivi, 2020
Objective: Cardiac catheterization continues to be a major source of radiation exposure for patients with congenital heart disease. As children are more prone to both deterministic and stochastic effects of radiation, every effort should be made to ...

Development of an optically stimulated luminescence radiometer based on sodium chloride and gold nanoparticles for improving radiation detection in radiography

Journal of Applied Clinical Medical Physics, Volume 27, Issue 5, May 2026.
Abstract Purpose To evaluate sodium chloride doped with gold nanoparticles (NaCl + GNPs) as a low‐cost, reusable optically stimulated luminescence (OSL) material for diagnostic radiology, and to benchmark its luminescence performance against the commercial standard, aluminum oxide doped with carbon (Al2O3:C).

Infrared Nanocrystals for Space Application: Hardness to Irradiations

Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
This article investigates infrared HgTe nanocrystals under X‐ray and ion irradiation, revealing remarkable radiation hardness. It uncovers distinct degradation mechanisms and shows that the nanomaterial outperforms integrated electronics. The results position colloidal nanocrystals as promising candidates for resilient space and harsh‐environment ...

Procedural Outcome of Modern Percutaneous Coronary Intervention in Proximal Chronic Total Occlusions

Catheterization and Cardiovascular Interventions, Volume 107, Issue 6, Page 2041-2049, May 1, 2026.
ABSTRACT Background Long‐term outcome in patients with chronic total occlusions (CTO) depends on the target vessel and proximity of the lesion. Aims To investigate of the target vessel was associated with procedural efficacy and safety in patients with proximal CTO lesions.

Air-kerma evaluation at the maze entrance of HDR brachytherapy facilities

Journal of Radiological Protection, 2014
In the absence of procedures for evaluating the design of brachytherapy (BT) facilities for radiation protection purposes, the methodology used for external beam radiotherapy facilities is often adapted. The purpose of this study is to adapt the NCRP 151 methodology for estimating the air-kerma rate at the door in BT facilities.

Monte Carlo modeling of the field size dependency for thin window plane‐parallel chambers in kilovoltage X‐ray reference dosimetry

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Clinical dosimetry for kV X‐ray radiotherapy beams requires calibrated ionization chambers. When the clinical field size differs from the field size used for chamber calibration, in‐air measurements result in a different magnitude of scatter from the detector stem or body housing affecting the sensitive volume.
