Shielding of Cosmic Radiation by Fibrous Materials

open access: yesFibers, 2021
Cosmic radiation belongs to the challenges engineers have to deal with when further developing space travel. Besides the severe risks for humans due to high-energy particles or waves, the impact of cosmic radiation on electronics and diverse materials ...

An Optimized Solution to Long‐Distance Flight Routes Under Extreme Cosmic Radiation

open access: yesSpace Weather, 2022
During extraordinary space weather, cosmic radiation can be significant enough to pose a threat to aircrew health. Traditional methods of reducing massive cosmic radiation exposure include flight cancellation, lowering flying altitudes, and flight ...

Dependence of cosmic ray component in background of atmosphere surface from solar magnetic activity

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2021
Using Geant4 toolkit the changes of the flux density and of the dose rates of the secondary cosmic radiation at the heights up to 50 m from the land surface (at a depth of atmosphere about 1030 g/cm²) and depending on solar magnetic activity were ...

Estimation of Cosmic-Ray-Induced Atmospheric Ionization and Radiation at Commercial Aviation Flight Altitudes

open access: yesApplied Sciences, 2022
The main source of the ionization of the Earth’s atmosphere is the cosmic radiation that depends on solar activity as well as geomagnetic activity. Galactic cosmic rays constitute a permanent radiation background and contribute significantly to the ...

Living With Cosmic Radiation

open access: yesPerspectives of Earth and Space Scientists, 2022
The last two decades of cosmic ray research have been eventful, to say the least. The Voyager spacecraft explored the outer‐most regions of the heliosphere and eventually left our local astrosphere to explore the galaxy.

Considering light-matter interactions in Friedmann equations based on the conformal FLRW metric

open access: yesJournal of Advanced Research, 2023
Introduction: Recent observations indicate that the Universe is not transparent but partially opaque due to absorption of light by ambient cosmic dust. This implies that the current cosmological model valid for the transparent universe must be modified ...

Influences of cosmic radiation, artificial radioactivity and aerosol concentration upon the fair-weather atmospheric electric field in Lisbon (1955–1991) [PDF]

open access: yes, 2006
The atmospheric electric field is influenced by cosmic radiation, radioactivity and aerosols. In this work we investigate the existence of: (i) correlations between relative anomalies of annual values of atmospheric electric field and cosmic radiation ...
