BT and radiation

[hoehingday]

surely BT must give out radiation, but is it dangerous to health? im talkin about using it for long periods of time, e.g. the jabra has 8hrs talk time, imagine using only the headset to receive and make calls, would it affect ur health?
i have the motorola hs 810.

Bluetooth operates at the 2.4GHz frequency.
Just to make a comparison here are some other devices that run at 2.4GHz:


Cordless Phones
802.11b (WiFi) and 802.11g Wireless Networks
Florescent Lighting
Microwave Ovens

oic, so relatively safe then.
thanx for that, was getn worried there :p

Beside Cordless Phones, I assume people do not use the other
devices in the list above close to their head for longer periods as may be the case for headsets. Basicly this comparation does not say much.

You have to wait and see if anybody gets brain tumor that can be connected to heavely usage of bluetooth headset. :rolleyes:

Well the comparison wasn't to deem BT as safe. It was to show that even if you don't use BT, you are probably going to be exposed to similar radiation from one of the other devices on the list.

Cordless phones you use for long periods of time close to your head. BT has very limited signal strength as compared to cordless phones. How safe are they?

Many people work in offices where they sit under fluorescent lights all day...they are being bombarded with 2.4ghz frequencies as well.

Microwave ovens use an astronomical amount of radio waves to cook food. So much so, that a ratio of the two device categories would seemingly approach inifinity/constant. The leakage of radio waves from your microwave are probably a billion times more likely to hurt you then a full day on a 2.4ghz phone device..(whether that be bluetooth headset or cordless phone).

Just for ****s and giggles...here are some interesting properties of radio waves at 2.4 ghz (taken from howstuffworks.com)

They are absorbed by water, fats and sugars. When they are absorbed they are converted directly into atomic motion - heat. Microwaves in this frequency range have another interesting property: they are not absorbed by most plastics, glass or ceramics.

so would it be SAFE to say that using ur BT headset is SAFER than using ur handset?
there was all this hype about first the dangers of using ur handsfree earpiece and then about long period of use of ur headset, but there hasnt really been anything to do with dangers of bluetooth. Is it because its relatively new or because its relatively safe?

Some food for thought...

your cell phone operates on .8/.9/1.8/1.9GHz frequency (depending on where you live and what carrier you are using).

Now think about how strong a signal your cell phone must put out in order to talk to cell sites in your area.
Now think about how that compares to your bluetooth devices which are no more than 10 meters apart.

the SAR rating of a phone can not go beyond 2W/kg of a 10gm mass... we are talking of 2W (watts)...

according to SE their BT headsets are rated at 0.001 W or 1mW, see link below for health related issues with SE

in my book BT headset are healthier to wear, both on RF side and on driving side :)
