Air carrier crews are occupationally exposed to ionizing radiation, principally from galactic cosmic radiation. To promote radiation safety in aviation the Federal Aviation Administration has: issued educational material on the nature of the radiation received during air travel; recommended radiation exposure...

EM radiation can travel through empty space. This differentiates it from other types of waves, such as sound, which need a medium to move through. All forms of EM radiation reside on the electromagneticspectrum, which ranks radiation from lowest energy/longest wavelength to highest energy/shortest...

FIGURE 3. Total hemispherical emissivity of Inconel 718: (a) shiny, (b) oxidized in air for 15 min at 815 °C, (c) sandblasted and oxidized in air for 15 min at 815 °C. Plank has developed a formula for the monochromatic emissive power of a black body from quantum mechanics as sh...
In general, any charged particle that undergoes acceleration will emit electromagnetic radiation; thus, an accelerating charged particle will emit bremsstrahlung when it is made to decelerate upon being deflected from its path of travel by collision or near encounter with an atomic nucleus. Charged ...
Wireless infrastructure on passenger planes has documented potential to disable or even kill during flight.At high altitudes, one man’s Wi-gratification can be another man’s cancer acceleration, heart malfunction or seizure. Inescapable microwave irradiation during air travel can trigger brain edemas...
Although gamma rays are electrically neutral, they can ionise atoms directly throughphotoelectric effectandCompton effect(Mcalister, 2012). It travels at speed of light and can travel thousands of meters in air before spending their energy (Kaur et al., 2018). Thus, they can easily penetrate ma...
