Within this context, we consider Hawking radiation as a mechanism to produce both dark radiation and dark matter. If the early universe included a black hole dominated era, we find that Hawking radiation will produce dark radiation at a level $\\\Delta N_{m eff} \\\sim 0.03-0.2$ for ...
Thus, they can easily penetrate matter and pass through human body effortlessly as well. It can damage living cells as it slows down and transfers its energy to the surrounding cells. The nature of gamma radiation makes it very dangerous to the people who deals with it. On the hand, there...
microwave sky, which will track faint signatures of matter and radiation interactions across cosmic time, exploit the CMB as a multi-faceted cosmology probe, and construct a three-dimensional picture of the various components of the cosmic web, across space and time, using five main observables:...

As science and technology had advanced, radiotherapy had transitioned from the two-dimensional to the three-dimensional era and finally to the current intensity-modified radiotherapy. Because of this, we have improved our ability to shield important organs or healthy tissues from radiation [31, 32]...
1.Condensed water vapor in cloudlike masses lying close to the ground and limiting visibility. 2. a.An obscuring haze, as of atmospheric dust or smoke. b.A mist or film clouding a surface, as of a window, lens, or mirror. 3.A cloud of vaporized liquid, especially a chemical spray ...
[111,112]. Bacteria, fungi, and archaea are among the soil microbes that are essential for the breakdown of organic matter, the cycling of nutrients, and the promotion of plant growth [113,114]. Reductions in microbial biomass, diversity, and activity can result from raised UV-B radiation'...
In 2023, the Common Sense Oncology (CSO) movement was launched with the goal of recalibrating cancer care to focus on outcomes that matter to patients. We extend the three CSO pillars - evidence generation, interpretation and communication - to radiation oncology and advocate for better evidence ...
Microwave radiation that penetrates space throughout the universe, postulated to be residual electromagnetic radiation originally emitted by warm matter in the universe approximately 400,000 years after the Big Bang. Also calledcosmic background radiation,cosmic microwave background,microwave background. ...
This required the heralding in of a new era, that of molecular radiation biology. As molecular biology developed in time, knowledge of genes and pathways increased exponentially. This was facilitated by a parallel development of techniques to study them which became progressively more sophisticated ...
