Gamma radiation causes damage to living tissue, which makes it useful for killing cancer cells when applied in carefully measured doses to small regions. Uncontrolled exposure, though, is extremely dangerous to humans. This article was updated on March 17, 2022, by Live Science contributor Adam ...
Because mobile phones and other wireless gadgets are held close to the body and are also used very frequently, these devices are potentially the most dangerous sources of EM radiation. This gave rise to an increasing concern for any unknown effects that may prove to be detrimental to human ...
where E (J) is the energy, hPI (= 6.626 × 10− 34 J s) is Planck's constant and f (Hz) is the frequency of radiation. As the frequency increases, the energy per photon increases and the radiation becomes more harmful and dangerous to health. Therefore, electromagnetic radiation c...
This protects the Earth from the radiation, which can be dangerous to life. It also protects the satellites that we use for communication. (What protects the Earth from the solar wind ? the earth's magnetic field) (The Earth’s magnetic field protects the Earth from the solar wind.) Magne...
We are surrounded by natural and generally harmless sources of electromagnetic radiation all the time and always have been. But, since the Industrial Revolution, we have added a lot of it to our immediate environment. The question of whether this is actually dangerous first got public attention ...
Wireless radiation and man-made electromagnetic radiation – radio-frequency electromagnetic fields (RF/EMF) cause harmful biological effects in humans and living things. We are being increasingly exposed to man-made microwave radiation – in our homes, schools, towns, cities, parks, hospitals, from...
aMobile phones should carry a label if they proved to be a dangerous source of radiation, according to Robert Bell, a scientist, And no more mobile phone transmitter towers should be built until the long-term health effects of the electromagnetic radiation they emit are scientifically evaluatedm...

With the rapid development of unmanned aerial vehicle (UAV) technology, the use of the UAV platform for measurement can not only improve work efficiency but also avoid the significant losses that may be caused by humans working in dangerous areas. Therefore, we propose a broadband frequency ...
Microwaves can be dangerous. If you were to put a person in a microwave oven, it would heat the water molecules inside the body and cook the internal tissues. Infrared is what we, as humans, feel as warmth or heat. It is used in thermal imaging and night vision technology. Infrared is...
