Kad smo pisali o zračenju mobitela, rekli smo da je bolje koristiti žičani ili Bluetooth uređaj kako ne biste bili pod utjecajem zračenja mobitela. Postavljaju se pitanja da, budući da je i Bluetooth komunikacija oblik radio komunikacije, ne bi li trebalo postojati nešto što se zove Bluetooth zračenje. Je li Bluetooth zračenje loše i za ljude? Je li gore kao u slučaju mobitela?

Je li Bluetooth zračenje^{(Bluetooth Radiation)} štetno ili sigurno

Kada govorimo o zračenju mobitela, govorimo o visokofrekventnim radio valovima koji polaze od vašeg mobitela i moraju proći kroz labirint stubova mobitela prije nego što vaš glas zaista dođe do osobe koju ste pozvali na telefon.

U slučaju Bluetooth zračenja, valovi počinju s jednog od vaših uređaja koji je izravno povezan s drugim Bluetooth uređajem. Dobra stvar kod Bluetootha^(Bluetooth) je što je njegov domet (udaljenost) mali. Radeći na iznimno visokim frekvencijama, ovi valovi ne mogu prodrijeti u betonski zid. Obično je nekoliko metara u slučaju Bluetooth radio valova. Dakle, opasnost od Bluetooth zračenja, ako postoji, smanjena je na malo područje.

Ovo je u suprotnosti s mobitelom. Kada uputite poziv, radijske frekvencije bi trebale biti dovoljno snažne da dopru do tornja za mobitele. Uz mobitele, potreban vam je jedan ili više tornjeva za mobitele za upućivanje poziva ili slanje podataka putem interneta^(Internet) za mobitele . Stoga^(Thus) je zračenje mobitela rizičnije u usporedbi s Bluetoothom^(Bluetooth) . Kako biste saznali kako radio valovi utječu na ljude, pročitajte naš članak o opasnostima zračenja mobitela^{(dangers of cellphone radiation)} .

Mnogo je proučavano o potencijalu različitog raspona radio valova za utvrđivanje zdravstvenih problema. Mobilni telefon u upotrebi je opasan. Studija o Bluetooth zračenju do sada je davala različite rezultate. Ali ako primijenite logiku, Bluetooth ne može biti mnogo štetan jer radi na malom području, ne zahtijeva snažne radio antene, a time i smanjuje zračenje. Studije koje je provela Uprava za hranu^(Food) i lijekove^{(Drugs Administration)} ( FDA ) označavaju Bluetooth kao bezopasan.

“The majority of studies published have failed to show an association between exposure to radiofrequency from a cell phone and health problems”, says FDA on Bluetooth radiation

“Headsets can substantially reduce exposure since the phone is held away from the head in the user’s hand or in approved body-worn accessories.”, – FDA

Iste studije su pokazale da bi učinci Bluetooth zračenja bili tisuću puta manji od izravnog razgovora na mobitel. U prvom slučaju (gdje koristite Bluetooth slušalicu), vaš telefon ne dodiruje izravno nijedan dio tijela. Naravno, žičane slušalice će biti sigurnije od Bluetooth prijenosa podataka, ali ih ne preporučam jer bi blokirale vanjske zvukove koji su neophodni prilikom vožnje i sličnih stvari.

Bluetooth zračenje: sažetak^{(Bluetooth Radiation: Summary)}

Nema dokaza da Bluetooth zračenje može biti opasno za ljude. Većina centara za kontrolu bolesti označava Bluetooth^{(Disease Control Centres mark Bluetooth)} kao siguran. Glavni razlog je taj što iako se vozi na visokim frekvencijama, amplituda Bluetooth valova nema puno snage da prođe kroz predmete, zidove i druge slične prepreke. Dakle, općenito se može reći da je korištenje Bluetooth slušalica ili zvučnika sigurno ako se koristi u granicama. Ali dugotrajno izlaganje potencijalno može uzrokovati zdravstvene probleme.

Živimo u svijetu u kojem gotovo sve ovisi o radio valovima – od monitora za bebe preko komunikacija do zabave do GPS -a i još mnogo toga. Ne možemo – od sada – zamijeniti radio valove nikakvim drugim komunikacijskim medijem. Učinci Bluetooth^(Bluetooth) zračenja na zdravlje su mnogo niži u usporedbi s drugim oblicima. Iako će budućnost možda vidjeti neke alternative, vjerujem da će se ljudska tijela prilagoditi svijetu punom radio valova – ili reagirati na njega!

Is Bluetooth Radiation harmful to humans or is it safe?

When writing about cell phone radiation, we said that it is better to use a wired or Bluetooth device so that you аre not affected by cellphone radiation. Questions arise that sіnce Bluetоoth communication too, is a form of radio communication, shouldn’t there be somethіng called Bluetooth radiation. Is Bluetooth radiation also bad for humans? Is it as worse as in the case of cellphones?

Is Bluetooth Radiation harmful or safe

When speaking of cellphone radiation, we are talking about high-frequency radio waves that start from your cellphone and have to go through a maze of cellphone towers before your voice actually reaches the person whom you called on the phone.

In case of Bluetooth radiation, the waves start from one of your devices that is directly connected to another Bluetooth device. The good thing about Bluetooth is that its range (distance) is small. Working on extremely high frequencies, these waves cannot penetrate a concrete wall. It is usually a few meters in case of Bluetooth radio waves. Thus, the danger of Bluetooth radiation, if any, is reduced to a small area.

This is in contrast to a cellphone. When you make a call, the radio frequencies should be powerful enough to reach a cellphone tower. With cellphones, you need one or more cellphone towers for making a call or sending data over the cellphone Internet. Thus, cellphone radiation is riskier compared to Bluetooth. For knowing how radio waves affect humans, read our article on the dangers of cellphone radiation.

Much has been studied about the potential of a different range of radio waves to ascertain health problems. A cellphone-in-use is dangerous. The study on Bluetooth radiation has so far, given varying results. But if you apply logic, Bluetooth cannot be much harmful as it works in a small area, doesn’t require powerful radio antennas, and thus reduce the radiation. The studies conducted by Food and Drugs Administration (FDA) mark Bluetooth as no-danger.

“The majority of studies published have failed to show an association between exposure to radiofrequency from a cell phone and health problems”, says FDA on Bluetooth radiation

“Headsets can substantially reduce exposure since the phone is held away from the head in the user’s hand or in approved body-worn accessories.”, – FDA

The same studies have shown that Bluetooth radiation effects would be a thousand times less than talking into cell phone directly. In the former case (where you are using a Bluetooth earphone), your phone is not directly touching any body part. Of course, wired earphones will be safer than Bluetooth data transfer, but I do not recommend them as they would block out external sounds that are necessary when driving and doing similar things.

Bluetooth Radiation: Summary

There is no proof that Bluetooth radiation can be dangerous to humans. Most Disease Control Centres mark Bluetooth as safe. The main reason is that though riding on high frequencies, the amplitude of Bluetooth waves don’t have much strength to pass through objects, walls, and other similar obstacles. So one can generally say that using Bluetooth headphones or speakers is safe if used within limits. But long-term exposure could potentially cause health issues.

We’re living in a world where pretty much everything is dependent on radio waves – from baby monitors to communications to entertainment to GPS and more. We can’t – as of now – replace radio waves with any other medium of communication. Bluetooth radiation health effects are much lower compared to other forms. While the future may see some alternatives, I believe that human bodies will adapt to the world full of radio waves – or react to it!
