they can be dangerous in a very different way too, some nokia cell phones exploded in the face and hands of a women in the netherlands, don't know if you know that.... the battery just exploded for some reason, nokia sayd it wasn't an original battery, but that may just be ***

That is actually pretty funny. I didn't know cell phones could just explode when you are using them Anyways...they are from the netherlands, so what do you expect cold?

I have never thought mobiles to be a hazard to my health and I have been using them for quite a long time now.

Well, whatever it takes, there are still low radiation phones and mine is one of those. I am not at all bothered about the radiation cos it has a very low radition frequency.

I do believe that thhey emit an amount of electrical output just like any other device. Whether it is more or less or even dangerous is something I really don't care about.

I will agree with one of the posters about Nokia phones being more hazardous than others. For example, hybrid in Nokia 3310 (i think that's the model) is 1W strong, while in other phones it's about 0.2 to 0.4W (these are numbers I'm digging up from memory).

Anyway, the other point... Mobiles emit radio waves even when we're not talking... They will search for network, or communicate with providers control center. And, as everything that emitts something, I believe is potentialy harmfull.

And you all must agree with me, even if mobiles could kill in a year, do you think we would know? Mobiles take great share in market, and let's face it, none of us could live without one, right?

So, as harmful as mobiles can be, they are... necessary

Well i dont really care as long as i can talk and txt my mates (and the chicks)

I mean, a small ammount of radiation might make me mini-superman!

This calculation is not quite correct. It should be:
1 hr/day x 365 days= 365 hours
1 Watt = 1 Joule/s
365 hoursx 60 mins/hour x 60 secs/min = 1,314,000 secs
1,314,000 secs/year x 3 Watts = 3,942,000 Joules / year

So every year the cellphone emits 3,942,000 Joules, however not all of this gets absorbed by you.

Compare this energy release with that of sunlight:
The Sun emits 1370 Watts per square meter.
1370 Watts/m^2 x 0.5 m^2 = 685 Watts
1 hour x 60 mins/hour x 60 secs/min = 3,600 secs
685 Joules/s x 3,600 secs/hour = 2,466,000 Joules / hour

Compared to the energy of the Sun, the power of the cellphone is negligible. But the cellphone's energy is in microwaves while the Sun's energy is mostly in visible light, so we still can't tell if cellphones are that dangerous. I don't think that cellphones are that dangerous, but if you overuse them too too much they might be dangerous.


This calculation is also not quite correct:

The error is that weight does not accumulate, it only counts when the cars are on the bridge. If the bridge can hold up to 40000 kg, then that means it can hold a maximum of 40 cars at one time. As long as no more than 40 cars are on the bridge at one time, the bridge will not break.

Hope you guys enjoy this physics explanation!

I find this little gizmos to be very dangerous, but EM radiation is very unexplored area. But testing on myself, when talking on cellular phone for 5 hours in the row, next day my head was really sore and my ear was all red. Especially G3 generation has variable power output, depending on a speed you are achiving on the net.

Hey Guys,
THE QUESTION isn't are they safe? The REAL question is how fast do you want to "cook" your brain and how many brain cells can you afford to lose? Although the final evidence isn't in it's only a question of time before some slick lawyer brings a successful class action suit for the damage CP's are causing as the scientific evidence is accumulating daily. Remember the cigarette companys??. Am not saying the CPs industry is at fault, just that at some point this society has got to stop blaming others for an individual's total lack of common sense just because they were "told" it was safe.

Yes, mobile phones are dangerous, so are other things, like crossing the road or walking under a bridge. I would rather ask; Are they dangerous enough to affect our health? I would say no because the amounts of radiotion that are emmitted are quite low. Using the mobile phone is just one more calculated risk we take and if used correctly and carefully, there won't be any lasting effects. Obviously, someone who using the phone constantly is undertaking more risk than someone who is using it less frequently.
