Why are some electromagnetic waves harmful?

Last Updated: 27th June, 2020

Over-exposure to certain typesofelectromagnetic radiation can be harmful. Thehigherthe frequency of the radiation, the more damage it islikelyto cause to the body: microwaves cause internal heating ofbodytissues. infrared radiation is felt as heat and causesskinto burn.

Also asked, can electromagnetic waves be harmful?

The energy emitted by electronics isnon-ionizingradiation, meaning it does not have thecapability tobreak chemical bonds. While electromagneticradiation cannotcause immediate damage, it does interactwith our bodies,which can potentially lead to indirectdamage, especiallyfollowing long term exposure.

Secondly, why are electromagnetic waves important to humans? However, the Earth's atmosphere protects us fromexposureto a range of higher energy waves that can beharmful tolife. Gamma rays, x-rays, and some ultravioletwaves are"ionizing," meaning these waves have such ahigh energy thatthey can knock electrons out ofatoms.

Consequently, why are some electromagnetic waves harmful and others not?

because the speed of all electromagnetic wavesarethe same, wavelength decreases while frequency increases.Theshorter the wavelength, the higher the frequency. Why aresomeelectromagnetic waves harmful to you but othersarenot? the high frequencies and shorter wavelengthspenetratesbody easily.

Do electromagnetic waves cause cancer?

No mechanism by which ELF-EMFs orradiofrequencyradiation could cause cancer has beenidentified. Unlikehigh-energy (ionizing) radiation, EMFs in thenon-ionizing part ofthe electromagnetic spectrum cannotdamage DNA or cellsdirectly.

How does EMF effect the body?

They cause current to flow through the body totheground. Low-frequency magnetic fields induce circulatingcurrentswithin the human body. The strength of thesecurrents dependson the intensity of the outside magnetic field.Heating isthe main biological effect of theelectromagneticfields of radiofrequencyfields.

Do power lines give off radiation?

Power lines produce low-to mid-frequencymagneticfields (EMFs). These types of EMFs are in thenon-ionizingradiation part of the electromagnetic spectrum,and are notknown to damage DNA or cells directly, according to theNationalCancer Institute.

Is there proof that EMF causes health issues?

Some people worry about EMF exposure andcancer.Some studies have found a link between EMFexposureand a higher risk of childhood leukemia, butother studieshave not. Other studies have not found proof thatEMF exposurecauses other childhood cancers. Studies in adultsdid notprove that EMF exposure causes cancer.

How do electromagnetic waves travel?

These changing fields form electromagneticwaves.Electromagnetic waves differ from mechanicalwaves inthat they do not require a medium topropagate. This meansthat electromagnetic waves can travelnot only through airand solid materials, but also through thevacuum ofspace.
