Dear Hashem Azizi 

This is a very good question with a lots of possible answer depending on the device you are using, now in order to measure how much radiation a phone is radiating a term called SAR (specific absorption rate) this term stands if any device may cause cancer to our body, different countries have different maximum value of SAR, for example in United States: the FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over the volume containing a mass of 1 gram of tissue that is absorbing the most signal.

European Union: CENELEC specify SAR limits within the EU, following IEC standards. For mobile phones, and other such hand-held devices, the SAR limit is 2 W/kg averaged over the 10 g of tissue absorbing the most signal.

so before you buy a new phone make sure to check the value of SAR for the particular phone.

With Regards

Dhanu Chettri

Dear Sir,

we have not only the SAR discussion, at the new standards in Germany also the

athermic effects.

Yours Sincerely

I am very suspicious with anything manufactured by humans! Period.

Look at the automobile: spits pollution that kills and still everybody is happy to drive it around!

Thank you all friends to participate

Yes I belvied , any radiation or any chemical material  harmful on human.

regards

Yes, I think so, also all the electronic devices (may be Mobile Phone is ranked the first in the quantity and the quality of Radiation Harmful)

yes

For the question, "What are the health risks associated with mobile phones and their base stations?", they answered at WHO as follows:

"While an increased risk of brain tumours from the use of mobile phones is not established, the increasing use of mobile phones and the lack of data for mobile phone use over time periods longer than 15 years warrant further research of mobile phone use and brain cancer risk. In particular, with the recent popularity of mobile phone use among younger people, and therefore a potentially longer lifetime of exposure, WHO has promoted further research on this group and is currently assessing the health impact of RF fields on all studied endpoints." From the following Web page published on 20 September 2013:

http://www.who.int/features/qa/30/en/

Environmental exposure with the potential to lead to increased cancer risk is most likely higher due to exposure to outdoors air than it is for cell phones. The WHO in their 2014 Cancer Report (released in 2015) declared outdoors air a major carcinogenic factor. 

Yes it is , research has shown that already

Hello everyone

Yes they are harmful and I have experienced it personally....some 10-12 years back when I joined my first job…the location was far from my native… I used to talk  on mobile for 2-3 hours continuously, almost every day to my family members and friends...after 5-6 months I felt that after a talk of 15-20 min there was burning sensation in my ears…it was a unique type of feeling… difficult to explain in words...few days later it started paining…It required me to use medicine for around 15-20 days…It took around 6 months to recover from it completely and the main thing that helped me was I reduced the time over phone (not more than 20-30 min) and started using earphones...

Even today if I talk for around one hour over mobile I get a feel of same thing (not that intense)…so as per my experience mobile phones are very harmful for human health….especially keep your children away from them…

Regards

Naveen

Still not very clearly established that the radiation from mobile phones will be harmful to human health.

Yes its very harmful to human beings

Dear Hashhem,

If ionization caused by mobile transmitting power happens in the brain, definitely, it will be harmful. Ask a physician about the consequences!

The growing brain  tissue in children  may  be affected by  mobiles

http://www.medicaldaily.com/5-reasons-why-cellphones-are-bad-your-health-247624

Yes, I do and a lot of scientific evidences exists

Yes, the radiation from mobile phones affect the human health. There have been concerns, from both scientists and the media, that cell phone usage is linked to tumor development. 

Yes of course 

Yes....

Yes I do. I have learned that it is better to hold it away from one's body when using it.

I practice caution when using my cell phone. My car has bluetooth, so I do not touch my cell phone when I am driving, and at home, I turn on the phone speaker so that the phone is held at some distance from my head.It is better to be careful than later be sorry and maybe get a brain tumor.When microwave ovens first came out, they were viewed as releasing radioactivity, and some countries banned the use of such ovens. Over the years, the safety of microwave ovens improved, and now we see such ovens used in the countries in which they were at first forbidden. Time will tell regarding the brain tumors "due to using cell phones".

Dear Hashem ,

Do I believe , nope !!!!!!!!! I know initially when microwave heating came people said this and that ... Well , now can't do without that.

So it is with mobile , anything with overuse will have its impact as simple as eating ...

I do think there are risks associated with cellphone usage, but I also think no clear understanding exists as to what that risk is. Industry doesn't want fear raised over their product, yet the people who use them equally do not want to hear any talk of risks to human health and safety. Microwave ovens are often cited as an example of radiation devices that are safe, but the exposure time with these devices is minimal. Cellphones are used daily and throughout the day by ardent users and their health effects are often visible. 

With all that said: I do think the increase risk to health for cellphone usage is small, but it is advisable to keep their use at a minimum, maintain the power of devices low, as well as, the towers. I do think in time, the power requirements will steadily go up, therefore, the health risks will climb as well. 

Mobile is very useful service for the entire human beings as it helps the contact & the mobility of the mental expression more convenient & more practical .

This is one of the positive sign of this research but at what cost students & young generation forget their basic action of their life career & while going all working their mind moves in the direction of the tone or the ring of mobile. To me , it is bound to come in the mind & development of healthy growth of the young generation.

This is my personal opinion 

Mobile phone radiotion may be harmful only when there is a dependence syndrome.

https://en.wikipedia.org/wiki/Mobile_phone_overuse

I think you need to be more concerned about the effect cell phone usage is having on reducing attention spans in people, rather than radiation risks.

Dear Vikas Ramachandra it could waste the time too

@Ishag Adam: Agreed!

I think that  mobile has an effect  on public health and  the concentration of the user, especially when used  Long  time of  day

I do not think it is a matter of commenting here what each scientist outside this discipline thinks (his opinión), but rather of listening to the experts on the effects of electromagnetic radiation on health. In addition to the links I posted in early November, this German recent brochure may be a good start for information:

Best regards

One of the challenges of being here at RG is to accept the fact that some people believe "otherwise", and we cannot just push away their feedback even if we believe that we are right and "they are wrong."

Dear Hashen,

Please check the following.

I want to share my personal experience.

Whenever I put my cell phone in my front pocket (right side chest) for some time e.g. 15 or 30 minutes I feel pain and anxiety. And that is why I keep my phone in trouser pocket.

When I make long duration (more than 10 minutes, e.g.) I feel irritated.

Thanks for initiating such a very useful topic.

Regards.

 I think so indeed. Please read the following links which explain how these cell phones impact on human health. Moreover, there are impacts on other living communities in our environment. Also, there is a great effect on social mode and behavior which it discussed on the RG site.

1. From WHO site: http://www.who.int/mediacentre/factsheets/fs193/en/

2. http://www.who.int/mediacentre/factsheets/fs193/en/

Yes I do and all your responses confirm my belief. But it seems that such harmful risks are not stopping the digital natives from using them especially for learning in higher education. In fact, the trends and issues for mobile devices now show that wearable technology is going to be the next fad as my preliminary reading on the topic shows.

Many thanks,

Debra

It is not a mater of believing, it is a fact and well put here.

Its effect is heard here and there in publications/ news papers etc.. Being a necessity, we can not avoid this gadget, but we should use it only for communication for other activities we may stick on to computers.

In the name of ALLAH

Hi to dear friends.

For answer to it we must survey anatomy of body and frequency work it (in level one).

For example in OFDM , device work together and have not effect with other.

Do you know about it ?

In level two .     survey sum power of it.

We must enquire what are the risks of using mobile phones to avoid hazards.

Dear Colleagues,

Good Day,

"....   Why is there concern that cell phones may cause cancer or other health problems?

There are three main reasons why people are concerned that cell phones (also known as “mobile” or “wireless” telephones) might have the potential to cause certain types of cancer or other health problems:

• Cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas. Tissues nearest to the antenna can absorb this energy.
• The number of cell phone users has increased rapidly. As of December 2014, there were more than 327.5 million cell phone subscribers in the United States, according to the Cellular Telecommunications and Internet Association. This is a nearly threefold increase from the 110 million users in 2000. Globally, the number of subscriptions is estimated by the International Telecommunications Union to be 5 billion.
• Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. However, improvements in cell phone technology have resulted in devices that have lower power outputs than earlier models."....

Please, see the link for more information.....

https://www.cancer.gov/about-cancer/causes-prevention/risk/radiation/cell-phones-fact-sheet

Yes, I think so too.  Cell phones may cause many problem for our health like cancer !

I do not doubt the statements that many RF members have made here. I also think that there are other "sources of harm" that some nations have been exposed to. Who is keeping track of cancer incidence cases in such countries? 

Dear Hashem

I believe that, mobile phones radiation has negative on brain and mole on vessels.

I think in near future scientists resolve this problem.

Good luck.

Dear all and more effects on the kids.

Regards

Raid

Yes. Especially when people carry 2-3 phones..

Yes

YES SURE

We have to be very careful when using mobile phones because there are many studies and researches prove this, but we don't care because these phones became  very important in our life and we cannot get a way from. But we must take care.

Very true , mobile phones are harmful for humans from their radiation. They radiate in human penetration frequency range, which is  disturbing the structure of  human basic elements

that true we must be careful for using mobile.

Yes

Absolutely

ly true. See my publication on  effecects od radiations rrespnsible wide variert of disaeses bot onltu readition from cells bur microwave ovens and cell towers on various buildings etc  causing autism and various ebnormalities in  human populations. Nest time I will attach the paper or you may go to my RG account and llok for the paper by Sharma,Ahuja and Bir Bahadur.

Yeah The mobile radiations definitely causes the harmful effects on health. There are many studies proving this. The free radicals are also seen increased in long term use of cell phones . The so called Smart phones are really very Smartly destroying our health. I remember one of the facebook update of one mother about the selfie addiction developed in her daughter. In my views the slow encroachment in your brain is much more dangerous !!!!!

Yes, it is harmful! But it is not relevant, what others and I believe, we have to know it!

Did any body work on that ?

No evidence of harm demonstrated yet. Magnetic field readings suggest that EMF readings are too low to result in any biological effect in humans. 

Science will have to prove that beyond doubt.

Well , I am not a doctor or somebody from biology background.  How I see is - if eating meat and changes in lifestyle such as eating fast food (might have) detrimental effects , the phone radiation is also debatable . Now can we live without it is the question !!!!!

Yes it is harmful but Aparna madam rightly ponited out. .can we leave without mobile phones anymore? BTW neither mobile phones nor junk foods  nothing harmful we can really avoid anymore!!

Anything useful if used more to be adjusted is harmful to humans

Yes, I have already uploaded our publication some time back.Please read.

Yes I do 

Dear All.

Technology has its ups and downs.

This thread can derive answers that can be useful to knowledge acquisition if the word "BELIEVE" in the question, "Do you believe that mobile phones radiation may be harmful to human health?" is replaced with a word that asks for people's EXPERIENCES in the usage of mobile phones like the one shared by < @Naveen Bhatt >. And to pay attention to preventive usage habits like that of < @Raid Amin >.

Also, I have to say that the damages caused by radiations of any sort are not normally visible on people's health until over 10 to 15 years. Take the case of people who live close to high-tension electric transmission lines. It is good to know that not only phones cause radiations; other equipment like computer, microwave oven, running engines and a host of technology machines and devices.

But a person moderately exposed to radiations like those from phones and who is into good nutritional diet and enjoys a good amount of rest might not witness any health issue.

Thanks All.

There are comments about this by experts, it possibly may!
