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 ...

Laser polarization control of ionization-injected electron beams and x-ray radiation in laser wakefield accelerators [PDF]
arXiv, 2023 In this paper we have studied the influence of the laser polarization on the dynamics of the ionization-injected electron beams and subsequently the properties of the emitted betatron radiation in laser wakefield accelerators (LWFAs). While ionizing by a strong field laser radiation, generated photo-electrons carry a residual transverse momentum in ...

The effect of recombination radiation on the temperature and ionization state of partially ionized gas [PDF]
Mon.Not.Roy.Astron.Soc.437:2816,2013, 2013 A substantial fraction of all ionizing photons originate from radiative recombinations. However, in radiative transfer calculations this recombination radiation is often assumed to be absorbed 'on-the-spot' because for most methods the computational cost associated with the inclusion of gas elements as sources is prohibitive.

Effect of Microwave Wi-Fi Radiation at Frequency of 2.4 GHz on Epileptic Behavior of Rats
Journal of Biomedical Physics and Engineering, 2018 Background: Electromagnetic fields (EMF) with different intensities are widely used at home, offices and public places.Today, there is a growing global concern about the effects of human exposure to EMFs.

Modeling UV Radiation Feedback from Massive Stars: III. Escape of Radiation from Star-forming Giant Molecular Clouds [PDF]
, 2019 Using a suite of radiation hydrodynamic simulations of star cluster formation in turbulent clouds, we study the escape fraction of ionizing (Lyman continuum) and non-ionizing (FUV) radiation for a wide range of cloud masses and sizes. The escape fraction increases as H II regions evolve and reaches unity within a few dynamical times.

Statistics of Neutral Regions During Hydrogen Re-Ionization [PDF]
Astrophys.J. 580 (2002) L93-L96, 2002 We present predictions for two statistical measures of the hydrogen reionization process at high redshift. The first statistic is the number of neutral segments identified in spectra of high redshift QSOs as a function of their length. The second is the cross-correlation of neutral regions with possible sources of ionizing radiation.

Self-ionizing galactic winds [PDF]
, 2022 We present hydrodynamical simulations of galactic winds from star-forming galaxies including non-equilibrium ionization and frequency-dependent radiative transfer, processes that have remained largely unaccounted for in galactic wind studies. We consider radiation from massive stars, the metagalactic UV/X-ray background, and the self-radiation of the ...

Ionizing Radiation-Induced Immune and Inflammatory Reactions in the Brain
Frontiers in Immunology, 2017 Radiation-induced late brain injury consisting of vascular abnormalities, demyelination, white matter necrosis, and cognitive impairment has been described in patients subjected to cranial radiotherapy for brain tumors.

The impact of stars stripped in binaries on the integrated spectra of stellar populations [PDF]
A&A 629, A134 (2019), 2019 Stars stripped of their envelopes from interaction with a binary companion emit a significant fraction of their radiation as ionizing photons. They are potentially important stellar sources of ionizing radiation, however, they are still often neglected in spectral synthesis simulations or simulations of stellar feedback.

International Journal of Molecular Sciences, 2016 During the last few decades, improvements in the planning and application of radiotherapy in combination with surgery and chemotherapy resulted in increased survival rates of tumor patients. However, the success of radiotherapy is impaired by two reasons:
