Chronic Ionizing Radiation of Plants: An Evolutionary Factor from Direct Damage to Non-Target Effects

Plants, 2023
In present times, the levels of ionizing radiation (IR) on the surface of Earth are relatively low, posing no high challenges for the survival of contemporary life forms. IR derives from natural sources and naturally occurring radioactive materials (NORM)

Intermediate frequency magnetic field at 250.8 kHz does not induce DNA damage or “Adaptive Response” in vitro

Genetics & Applications, 2019
The aim of this study was to examine whether intermediate frequency (IF) magnetic field (MF) induces genotoxic effects or play a role in the induction of adaptive response after combined exposure to IF MF and ionizing radiation in leukocytes and in ...

Monte Carlo study of nanoparticles effectiveness on the dose enhancement when irradiated by protons

AIP Advances, 2023
Recently, the nanomedicine field has experienced considerable growth in research. The use of nanoparticles to enhance dose in radiation treatment was proposed and their potential effects can be indicated using Monte Carlo calculations.

Quantification of Artifacts and Image Distortions in 1.5 Tesla Magnetic Resonance Images of a Commercial Multi-Channel Vaginal Cylinder Brachytherapy Applicator Set [PDF]

Journal of Biomedical Physics and Engineering, 2023
Background: The BEBIG Portio multi-channel applicator provides better target dose coverage and sparing organs-at-risk compared to a single-channel cylinder. However, artifacts and distortions of Portio in magnetic resonance images (MRI) have not yet been

Double-strand breaks in lymphocyte DNA of humans exposed to [18F]fluorodeoxyglucose and the static magnetic field in PET/MRI

EJNMMI Research, 2020
Background Given the increasing clinical use of PET/MRI, potential risks to patients from simultaneous exposure to ionising radiation and (electro)magnetic fields should be thoroughly investigated as a precaution.

Implications of the COVID-19 pandemic on self-reported health status and noise annoyance in rural and non-rural Canada

Scientific Reports, 2022
The Canadian Perspectives on Environmental Noise Survey (CPENS), conducted between April 12th, 2021 and May 25th, 2021 coincided with the third wave of the COVID-19 pandemic. Canadians 18 years of age and older (n = 6647) reported the degree to which the
