Radiation Safety in Practice: A Cross‐Sectional Study on Radiographers' Knowledge, Awareness and Adherence to Personal Radiation Monitoring Devices in Resource Limited Settings

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study examined how well radiographers in five major Namibian state hospitals understand and use Personal Radiation Monitoring Devices (PRMD), a critical tool for occupational safety. While most respondents showed strong knowledge and awareness of PRMDs, many were unaware of their own radiation exposure and rarely reviewed their dose records ...

Intracellular acidification is a hallmark of thymineless death in E. coli.

open access: yesPLoS Genetics, 2022
Thymidine starvation causes rapid cell death. This enigmatic process known as thymineless death (TLD) is the underlying killing mechanism of diverse antimicrobial and antineoplastic drugs.

Technique considerations for implementing volumetric‐modulated arc therapy for total body irradiation within an Australian tertiary institution

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 165-172, March 2025.
In 2020, our institution transitioned to the Eclipse™ treatment planning system and to Truebeam® linear accelerators with 6 MV and 10 MV energies. The linear accelerators were installed in smaller bunkers that could not accommodate 400 cm FAD. A multidisciplinary team within the institution was created to evaluate existing total body irradiation ...

Linearity Test for Harshaw TLD (Type: TLD-100H) Base on Individual Calibration Method [PDF]

open access: yesNuclear Science, 2019
The testing of the individual monitoring instruments is important to demonstrate the performance of the instruments to give accurate measurements in workplace environment. In this research, 18 Thermoluminescence dosimetry (TLD) units were calibrated individually at surface water phantom and exposed with 60Co source at block 32 in Malaysia Nuclear ...

Tumour Dose Estimation using Automated TLD Techniques [PDF]

open access: yesActa Oncologica, 1998
Lithium fluoride (TLD-700) dosimeters were used to measure exit surface absorbed doses in external beam radiotherapy using an automated TLD reader. Delivered tumour absorbed doses were derived from these measurements for head and neck, pelvis and breast treatments.

Automated Imaging of Cultured Bacteria in Picoliter Droplets by Coherent Anti‐Stokes Raman Scattering and Two‐Photon Excited Fluorescence Microscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
We present an automated system that combines an image‐based fuzzy logic controller for precise positioning of microfluidic picoliter droplets with nonlinear microscopy, using CARS and TPEF modalities for detailed analysis of droplet composition. Time series and z‐stack images of E. coli, B. subtilis, and M. arborescens were recorded.

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

open access: yesPeople and Nature, EarlyView.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.

Safety of denervation following targeted lung denervation therapy for COPD: AIRFLOW-1 3-year outcomes

open access: yesRespiratory Research, 2021
Background Targeted lung denervation (TLD) is a novel bronchoscopic therapy that disrupts parasympathetic pulmonary nerve input to the lung reducing clinical consequences of cholinergic hyperactivity.

3D‐Printed Crosslinked Nanocellulose‐MXene Hydrogels and Aerogels with High Strength and Conductivity

open access: yesSmall, EarlyView.
This study presents a robust strategy for 3D printing conductive, mechanically resilient MXene–CNF composite structures using a single‐step freeze‐induced crosslinking method. The printed architectures remain stable in both wet and dry states, exhibit high electrical conductivity and mechanical strength, and demonstrate practical application in fully ...
