Article Synopsis
- Hospital and nursing-care-acquired infections are increasingly problematic, especially for older adults, with aerosol transmission of pathogens being a key concern during epidemics like COVID-19.
- Understanding how airborne particles carry pathogens is vital for controlling diseases like influenza and SARS-CoV-2, as smaller particles can stay airborne and contribute to transmission.
- The review discusses methods for studying aerosol particle behavior in the lungs, various numerical lung models, and effective air purification techniques to enhance safety in healthcare settings, particularly for vulnerable elderly populations.
To enhance stakeholder engagement and foster the inclusion of interests of citizens in radiation protection research, a comprehensive online survey was developed within the framework of the European Partnership PIANOFORTE. This survey was performed in 2022 and presented an opportunity for a wide range of stakeholders to voice their opinions on research priorities in radiation protection for the foreseeable future. Simultaneously, it delved into pertinent issues surrounding general radiation protection.

- Laser cladding with H13 steel powders produced various aerosol particle sizes, which were studied using specialized measuring techniques.
- The analysis showed a clear relationship between the particle size, concentration, and oxidation state, with ultrafine particles being mostly oxidized.
- Larger particles retained properties of the original steel powder but showed compositional changes, highlighting the effects of the laser process on material transformation.
Objectives: The aim of this study was to provide particle number and mass deposition rates of submicron particles in the human airways as inputs for toxicology and other areas of aerosol science.
Methods: Scanning Mobility Particle Spectrometer was used to measure the number concentrations and size distributions of the ultrafine urban particles during summer and winter in Budapest. The Stochastic Lung Model (SLM) was applied to calculate number and mass deposition rates of the inhaled particles in different anatomical regions of the airways.
