Radiation increased after installing ios5 on iphone 3gs?

by ShEERa06 / June 28, 2013 1:35 AM PDT

I purchased an iphone 3gs a couple of years ago; about 1 and 1/2 years ago, I then upgraded to ios 5 on my phone to obtain some of the iphone 5 features on my phone. I am concerned about the SAR, though; does the ios 5 cause the radiation level to be what it would be on an iphone 5 or is it the level that would be for an iphone 3gs? Any help is appreciated, and thanks very much!

In order to get better coverage almost all cellular towers are putting out more such radiation so you should take precautions around them if this bothers you.

The phone you can turn off or use a head set or head protector unit. Examples at http://www.lessemf.com/personal.html

What's happening is, there are more cellular sites. The amount of radiation isn't changing per se.

I worked in the defense industry and over the years some of our old radars began to have range and more issues as the cellular networks came in. It didn't take much (a van with antennas and spectrum analyzers) to see that the RF or "soup" had increased so there is much more RF energy around us as the years progressed.

All very interesting stuff and there are some folk that have created new markets for the head gear I linked to.

While I only saw such a full EMI suit in a very odd system (an electric rail gun test area) we would always shut down the megawatt radar before going to work in that area.

and we would shut down the kilowatt transmitters

when working within 15 feet of them.
The 50 watt transmitters we would tune with a pencil held next to the RF outlet and tune for maximum spark gap. (Pretty with the lights out)

To answer the original question though, upgrading to iOS 5 did not increase the amount of radiation from the iPhone 3GS's radio.

So the radiation was not increased from the 3GS radio...great! Since my 3GS now has the iOS 5, would there be increased radiation by making phone calls, texting, or accessing the internet?

(SAR for iphone 3GS is .79 and SAR for iphone 5 is 1.18)
(Thanks!)

(when I said "increased radiation" on the post I just made, I meant in terms of going from an iphone 3GS's iOS to the iOS 5 upgrade onto my 3GS phone)

I don't think so.....

A change in the iOS is not a hardware change. You are still using the same phone and it shouldn't make any difference. You might be able to find a difference between a 3GS and a 5.
