Does YOUR cell-phone emit Radiation?
72
We all are extremely fond of our Cell-phones! Can't imagine a life with out it. Besides, having the world in our hands (smart phone) it is also a very handy gadget especially in times of distress or loneliness.
- Life without Cell Phone
Have you imagined life without your cell-phone? This hub talks about experimenting yourself without your cell phone and other topics regarding the above. Try it!
But, did we know that Cell phones emit electromagnetic radiation. X-rays is another example of electromagnetic radiation.
Radiation is energy that comes from a source and travels through material. This ionizing radiation produces charged particles in matter. Ionizing radiation is produced by unstable atoms and have excess of energy.
World Health Organization (WHO) has classified radiation coming from mobiles as carcinogenic. Additional research is being done into the long term usage of this instrument to gather information regarding the above statement.
Every phone has to pass a Federal Communication Commission (F.C.C) certification. A cell phone's maximax SAR level must be less than 1.6W/kg (watts per kilogram). In Europe, the level is 2 W/kg, while Canada allows a maximum of 1.6 W/kg.
The SAR level listed in the charts represents the HIGHEST SAR level with the phone next to the ear. SAR level varies between different transmission bands and different testing bodies can obtain different results. It is also possible for results to vary between different editions of the same cell phone.
The table below includes lists of cellphones by brand name.

IF your phone is in the high emission range, it is wise to change it or try to use a blue-tooth to talk. Avoid keeping this phone near your body.

I worked in the industry for my whole career and just recently retired. As to your question? Well, first of all, all Cell phones emit radiation. That is how they communicate, through the transmission of data over high frequencies. So your question is a Moot one.
But as to the SAR level? You are right on about knowing the SAR level of your phone. This level was set quite a while back as a standard that all phones should be held to.
BUT, you also need to remember that this transmission/radiation level is also an indication of the efficiency of your Cell phone for communications. By that I mean that a phone with a very low SAR level is probably going to have communication problems (dropped calls, etc.) in more remote areas where there are not as many Cellular repeater stations (read towers).
OH! and by the way, that number that you reported is not necessarily the level of your personal phone. This test is complex and time consuming, so the number publicized is a result of a very small statistical sampling of production phones.
What do I do? I use my Cell (Smartphone) extensively through-out the day. Do I worry about SAR, of course I do. I also, have been in the habit that all manufacturers recommend. I use my earpiece and I use the Speakerphone ........ a Lot!
And to keep things like this in perspective, you should look up the level of radiation you receive from a Cell phone compared to that of an X-Ray, that you mentioned.
And, Yes, looking back at what I just typed, I have to admit, I am an Engineer.
I've been reading more and more about radiation and the use of cell phones. Thank's for a well written hub. I can see that you put much research into this..Thank you Ruchira..
I never thought I will ever attach myself to a phone... but now it keeps me connected to all my beloveds and friends. Without it I feel like being alone in the middle of a desert. So what shall I do?
Hello Manoj,
Apologize the delay in acknowledging your comment. Even people in the US are concerned about latest gadgets, which carrier and tariff.
With the increasing cases of auto-immune diseases prompted me to look into the above topic.
Thank you for your concern and comment...appreciate it!
Hi Donn,
Such a pleasure to get an extensive input from you. I agree that cellphones work by emitting radiation. This is a primary hub indicating about it since; many of us are unaware and keep it close.
I agree that SAR level is an approximate value (as indicated in my text above)
SAR level is also an indication of communication problem thus, we need to take appropriate measures by using a blue tooth or speaker phone.
In my text, I am not comparing the radiation of a cellphone to X-ray BUT, I have given an example of electromagnetic radiation i.e X-ray.
Your comments to my hub was truly appreciated. Thanks for stopping by.
Yes, by your intrinsic comments above...I have no doubt that you are an engineer :)
Hi Ruby,
LOVE your profile pix:)
I am glad that you liked this hub. With the rise in auto-immune diseases and humans glued to their phones...thought of writing this hub for awareness.
hope you had a happy thanksgiving and many more reasons to be thankful for :) Cheers!
Hi MartieCoestar,
We ALL are attached to our phones. I have written a hub on it as well.
I agree with distances and busy schedules, phone is like our left hand :) Try using a blue tooth or use the speaker when talking to people. Also, don't keep the phone in your pocket but, in your purse which help prevent radiation to be absorbed in the body.
Good luck!
Moderate use of cellphones is essential for us to escape radiation. Thank you Ruchira for your wonderful hub.
Hi Mathira,
Alas, with the speed technology is moving with..our usage of phone is not getting limited. However, we should choose those gadgets which emit out far less radiation than others. Also, avoid using phone close to us by using a blue tooth device.
Thanks for stopping by...appreciate your input and Welcome!
So interesting Ruchira! I tried to do an EEG on myself while holding a cell phone and talking on it - wanted to see if it affected the height or width of my brain waves...only problem was both the machine and cell phone operate on the same band width of electricity so it kept blowing my cell signal out whe I would get too close to the only machine I and available:) lol.
I knew a little about this - but you did a sweet job here!!
Hi Kelly,
I am impressed by your experiment but, I guess gotta keep those two gadgets/instruments at different band widths. did not know about it until now...
Thank you for your insightful comment and am glad you found the above interesting.
Hi Ruchira, I agree with the above article. I minimize the use of cellphones as I know the harmful effects. I noticed that Europeans tends to use it less as compared to Asians and Americans. In Singapore, parents and children sitting in the park, walking on road, taking public transportation, it is too often used.
Cell phones are taken everywhere and we are just not aware of what this "little" gadget does besides keeping us stay connected...
I am glad you are using caution.
Thanks for stopping by with your comment and support.

Ruchira, Thanks for this hub so full of information. In India specially people are aware but not concerned with this aspect. The only thing which they are worried is about the price and the tariff plan of the service provider. Useful.
Namaskar and warm wishes,
Manoj
