Visualizing and Quantifying Impact with Mechanochromic Sensing Paints Based on Self‐Assembled Polydiacetylene‐Silk Core‐Shell Vesicles

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

A dose estimation for persons occupationally exposed to ionizing radiation in Montenegro [PDF]

open access: yesArchive of Oncology, 2008
Background: Persons occupationally exposed to ionizing radiation are subject to radiation protection due to potential harmful effects of radiation. Dose monitoring of professionally exposed workers is an essential regulatory measure in radiation protec ...

Assessment of radio frequency exposures in schools, homes, and public places in Belgium [PDF]

open access: yes, 2014
Characterization of exposure from emerging radio frequency (RF) technologies in areas where children are present is important. Exposure to RF electromagnetic fields (EMF) was assessed in three "sensitive" microenvironments; namely, schools, homes, and ...

A simulation study of a novel spiral volumetric modulated arc therapy for enhanced dose delivery efficiency and quality in radiotherapy

open access: yesMedical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Conventional volumetric modulated arc therapy (VMAT) is limited by its longitudinal field size for large targets, often requiring multiple isocenters, while Helical Tomotherapy (HT) offers superior longitudinal conformity but suffers from prolonged treatment times due to its narrow fan beam.

Analysis of Regulatory Inhalation Unit Risk Estimates for Cobalt: Comparison to Epidemiological Data

open access: yesRisk Analysis, Volume 46, Issue 4, April 2026.
ABSTRACT Several cancer potency estimates have been proposed by regulatory agencies to characterize the dose response of cobalt and/or cobalt compounds. The objective of this research is to investigate whether these proposed cancer potency estimates for certain cobalt substances align with the available epidemiology literature.

Some problems and errors in cytogenetic biodosimetry [PDF]

open access: yes, 2016
Human radiosensitivity is a quantitative trait that is generally subject to binomial distribution. Individual radiosensitivity, however, may deviate significantly from the mean (by 2-3 standard deviations).

Soft skills for medical physicists: Evolving a profession

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose Medical physicists are essential healthcare professionals who bridge the gap between technology and patient care, particularly in radiation oncology and medical imaging. With the profession expanding its clinical and global roles, the need for competencies beyond technical expertise—such as communication, leadership, and cultural ...

Nanoparticle behaviour in an urban street canyon at different heights and implications on indoor respiratory doses [PDF]

open access: yes, 2019
The amount of outdoor particles that indoor environments receive depends on the particle infiltration factors (Fin), peculiar of each environment, and on the outdoor aerosol concentrations and size distributions.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

open access: yesAdvanced Functional Materials, Volume 36, Issue 21, 12 March 2026.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
