Health Information About Cell Phones & Your Health

Submitted by on June 6, 2011 – 1:17 amNo Comment


That mobile phone you lug around in your bag has been associated with grave health issues such as infertility & presently a novel WHO trial states that they might be causal to brain tumor. Elucidated herewith is important health information for gaining an understanding about which cell phone models are having maximum radiation scores & ten pointers for reducing one’s exposures.

Several of us feel as though we couldn’t possibly exist without our mobile phones which have become such an integral part of our lives. However, could these amazing petite gadgets be making us ill in return?

Since long, study findings have cautioned that radiation from cell phones can be lethal & also cancer-causative, impelling several specialists in calling for safety rules.

The latest announcement by WHO specialists stated that medical proof associates mobile phone usage as being possibly cancer-causing. Yet, a number of scientists & governmental groups are disputing the notion that such gadgets are posing major risks to health.

Could our cell phones truly be harming our health? Here is all the necessary information one needs to comprehend regarding mobile phone radiation alongside pointers on lowering exposures.

Radiation – A Reality of Wireless Existence

RF or radiofrequency energy which is an electro-magnetic radiation type is emitted by every mobile phone, wireless computer or cordless phone.

The FDA points out that rather elevated amounts of some types of EME – for e.g. the form one gets while being X-rayed could be detrimental. This is since they are deemed IR (ionizing radiation) which translates to the fact that they augment chemical activity within the cells of our bodies.

However, mobile phones emit lesser EMR that are deemed as non ionizing.

Majority of the mobile phone’s radiofrequency energy is coming from their antennas that emit & receive one’s voice & text message.

As per NCI information, nearer the antennas are to the head, more an individual’s exposure.

The level could vary on the basis of an array of determining factors such as strength of mobile phones signals. Greater distance one is from a cell site, greater the radiofrequency energy necessary for connecting the calls & thus resulting in greater exposures.

And one noteworthy point is that one doesn’t even need to be on the call for having radiofrequency energy exposure. Moreover, even when phones are on stand-by mode, their antennas yet send & receive signals with the cell sites.

Exactly how much radiation does your mobile phone emit

The level of radiofrequency energy taken up by one’s body is generally computed as SAR (specific absorption rate) that could differ from device-to-device.

Mobile phones vended in the United States are not permitted on having a specific absorption rate crossing 1.6 watt per kg. of radiofrequency energy, as per the Federal Communications Commission rules. The latest smart phone line-up mostly has more specific absorption rate as compared to the earlier so-dubbed simple phone models.

Here’s a compilation of the top ten of the Environmental Working Group’s rating:
Model NameSAR Rating (W/Kg)
Apple iPhone 3GS1.19
Blackberry Bold 97001.55
HTC Nexus One by Google1.39
Motorola Brute i6800.86
Motorola CLIQ plus MOTOBLUR1.10
Motorola Droid1.50
Pantech Impact0.92
LG Chocolate Touch – VX85751.46
Samsung Mythic – SGH-A8971.08
Samsung Instinct HD– SPH-M8501.16
Mobile Phones – Scare or Health Danger

A number of trials done in the past – although largely on animal models & several of them in laboratories outside the United States – indicate that we are at a risk of health problems like cancer from being exposed to small amount of radiofrequency energy from our mobile phone.

Individuals who have been using a mobile phone for over a decade have a somewhat greater risk of developing gliomas, a brain tumor form, on that side of their heads where they clutch their phones, as per a Sweden-based trial done four years ago & appeared in the IJC medical journal.

Kids & teenagers might have greater vulnerability, partly since of their small-sized head & lesser thick cranium could be resulting in higher concentration radiation dosages, as per several trial findings done abroad.

For instance, an Israel-based trial conducted two years ago & printed in the ‘Community Dentistry and Oral Epidemiology’ cited that tumor of the salivary gland arises with greater frequency among patient types below twenty years of age, which is something that the scientists are attributing to mobile phone usage. The salivary gland is underneath the ears, near the location where one holds one’s mobile phone.

Still, several researchers along with the FCC state that in majority of the situations, additional studies haven’t been capable of reproducing the outcomes. Factually, majority of the printed trials do not associate radiofrequency energy emitted by mobile phones with cancers.

One thing that needs to be understood here is that majority of the study conducted on the effects of radiations have not be evaluated on human beings, however either on rodents or ‘head model’ meant for approximating the extent of energy absorption occurring. Head models aren’t analogous to human heads & every consumer needs to comprehend that several of such researches are not carried out on human-beings of any type.

Just last year, the biggest mobile phone trial till present – study spanning thirteen nations & dubbed ‘Interphone’ failed in finding an augmented risk of cancer among majority of its users.

However, this does not offer a clean shit either. The study found that individuals that were using their mobile phones most – over thirty minutes daily for more than a decade – had a somewhat greater likelihood of developing brain tumor.

Further Health Worries

In the interim, radiofrequency energy exposures due to mobile phones apparently affect our bodies, as per the FCC information.

The commonest worry is tissue being heated – the reason for warm sensation in the ear where one held the mobile phone for an extended span of time. Radiation tends to cause quicker vibration of tissue molecules similar to the manner in which microwave ovens are cooking our foods.

The eyes & testicular areas are duo regions of our bodies with specific vulnerability to tissue being heated up since there is squat blood supply to these regions for lowering temperatures, as per the Food & Drug Administration information.

Testicles being heated are another major worry for males carrying the devices in their trouser pocket which has been associated to diminished male fertility. An augmented likelihood of cataract formation is yet another likely danger, though the link has not been established.

Impact on our brains is also a likely worry, in the least with kids. A Denmark-based trial enrolling 28000 kids who were seven years of age discovered that those whose moms were regular cell phone users during pregnancy had a greater likelihood of having behavior-related issues, particularly when the children began using cell phone earlier on. But, the scientists have written that it would be rather early to state that mobile phones on their own were the reason.

Also another matter which is unrelated to radiation is mobile phone use causing skin condition like contact dermatitis, generally arising from allergic reaction to the phone’s nickel constituent. In case one develops rashes from one’s mobile phones then avert contact with skin by covering your phone with a plastic casing. Since these are notorious for being germ havens hence regularly cleaning the screens & keys by using antibacterial wipes.

Additional study is necessary

It could not be said that mobile phones are harmful as there just has not been ample independent study to state that they are not, either.

Researchers from Britain’s Imperial College of London who are part of a huge trial that would be tracking health of 250000 people using mobile phones over a two to three decade time span have mentioned that the common usage of cell phone is a comparatively current occurrence. There are yet major ambiguities which could solely be solved via observing health of huge numbers of cell phone users over a protracted span of time.

Health Information for ways of Reducing Radiation Exposure

In the interim, for people who would rather be safe instead of regret the consequences, here is crucial health information for limiting exposures to radiation from cell phones.

  • Go retro, head for landline phones with wiring whenever possible. In case you do not have one at your house then consider getting one installed.
  • Keeping one’s distance by using hands-free earpieces or mobile’s speaker facility. A warning – hands-free earpieces that use Bluetooth too are having wireless transmitters which expose users to radiofrequency energy. However, they are emitting a lesser level as compared to mobile phones; hence such hands-free device is yet in comparison safe.
  • Allow one’s finger tips in doing the talk. Text messages instead of talk on your phone & additionally keeping the phone at a distance from the head is advisable. However, avoid texting when behind the wheel.
  • Powering off phones when one does not require them.
  • Carrying mobile phones with antennas face away from oneself. Keeping the frontal side of keys faced to you & the backside or antenna to be outwards-faced that would be directing radiation away from one’s body.
  • Keeping the mobile in one’s suitcase. For avoiding testes tissues being heated males must skip lugging mobile phones in their trouser pocket & also not rest laptop on the lap.
  • Restrict or skip net surfing with mobile phones or disabling the wireless utility.
  • Totally charging your mobile phone as it would require ‘amping’ up when battery is low or receptions not up to the mark, augmenting radiation being emitted.
  • Avoid leaving your mobile phone close to your bedside while sleeping & instead using a battery-run alarm clock for waking up rather than the mobile alarm system. Firms have begun developing mobile applications which are capable of measuring amounts of radiation emitted like Tawkon that merges the mobile’s specific absorption rate score with info on the manner one uses it in relation to one’s body. Several models of Android & Blackberry are offering it though not on iPhones.
