Are WiFi's Safe?
Going wireless and concerns
Wireless radiation is an ongoing concern for many people and yet, most cannot imagine lasting a day without our mobile and tablet devices. The fast-paced life demands connectivity at all times and because of this phones have become a very important tool in daily life. There is an increasing concern on the possibility of any link between exposure to wireless radiation and health.
It is a fact that these mobile devices emit radiation in small levels. Radiation has an effect on the human body though but as to how, there is still no definite study on its specific impact to human health. To be on the side of caution, some practices will have to be put in place when it comes to using these devices safely.
1. There are no definitive studies yet but wireless radiation is a fact.
The effects of cell phone radiation to the human body has been the subject of much debate in recent times. In 2008, Dr. Khurana, an Australian neurosurgeon, became controversial due to his proposition that the use of cell phones increases the risk of brain tumors.It was said that cell phone use is deemed more dangerous than smoking. As expected, critics lambasted Dr. Khurana's findings since it has not undergone peer review nor published in any scientific journal.
A number of scientific studies on radio frequency radiation emitted by cell phones and cell towers found that such may cause modification in the human cellular makeup and could be dangerous to bodies at some levels. Another study held that the same RF may possibly cause DNA damage, a leading precursor of cancer.
There are independent studies that found the link between radiation and modification of brain chemicals. Cell phones make use of electromagnetic waves and emit a radio frequency (RF) and two, constant exposure to it could affect certain changes inside the body.
2. Minimize Wi-Fi and hotspots exposure
Wireless communication systems such as Wi-Fi are common place these days but that does not mean that they are frequency-free. Then, there is the use of many handy personal devices such as portable wi-fis. Anybody can now connect to the internet virtually anywhere and everywhere.
A wifi connection uses low-level electromagnetic waves to connect a user to the the main router. As of this time, it is difficult to measure and quantify exactly how much and what adverse effect this continuous exposure brings to a human body. Some people complain of sleep disturbances and headaches when exposed to wifi hotspots areas but nobody knows for sure of there is a link between this anomalies and wifi.
To be on the safe side, it is recommended that wifi hotspots in one's home should be turned off at night and when not in use so as to minimize any level of exposure to such electromagnetic waves.
3. Minimize cell radiation exposure
Cell phone radiation is measured by means of SAR or specific absorption rate. At some point, some of the waves emitted by antennas or cell phones get absorbed by the body and this is measured by the SAR. In the United States, the Federal Communications Commission or FCC recommends cell phone manufacturers to conduct their own SAR testing including severe or worst condition (highest levels) of operation of all frequency bands used. The FCC previously requires that the SAR of all cell phones sold to consumer be below 1.6 watts per kilogram.
To further reduce the risk of radiation, it is advised to keep a cell phone away from the body and refrain from putting it your pocket. It is also preferable to use a headset or earphone when talking over longer periods of time rather than putting the phone earpiece directly in your ear. Hold your mobile phone at its base rather than touching parts of the antenna. If you are a heavy cell phone user, it is a good idea to buy a hands free kit to further decrease exposure to radiation. When at home, make more use of your landline phone when making longer calls.
In other countries like Europe and Japan, the safety absorption limit is set at 2 watts per kilogram.
As a first step to prevent high RF absorption, only buy phone within this safety SAR limit or below. One may ask the cell phone technician or seller about the FCC ID number in a sticker somewhere. The FCC often located usually under the battery.
Using the FCC, one can log on to www.fcc.gov/oet/fccid to confirm if it is within the allowable levels. instruction on FCC ID number and then enter it in two parts, the first one being the Grantee number (3 digits) then the remaining numbers which refers to the Equipment Product Code, then press 'Search'. You will then find the grant of equipment authorization for this particular FCC ID number including data on highest SAR values for this unit.
4. Keep children safe and reduce their exposure to mobile and wi-fi devices
It has been found that radiation affects children easily due to their largely undeveloped brains so it is best to shield the young ones from such by making cell phone far away from them as much as possible or not allowing them to play with it for extended periods.
Don't make the mistake of taking a mobile phone to bed with you. Many sleep with their cell phones beside them, tucked under the pillows or worse harmlessly lying next to their heads.
At night, when you are not expecting an important call, try turning your mobile device off before you sleep or better yet, leave them outside your bedroom. In the closed confines of you car if it is possible for you not to turn on your phone, then do so since exposure is higly concentrated in a confined space. Besides, using a cell phone while you drive presents another risk to road safety.
5. Laptops, TVs and other devices emit the same radio frequency
Since laptops and other wireless devices emit the same RF, it is a safe practice to turn them off when not in use. This is all the more important at night when everyone is asleep. Doing so will also will reduce your energy consumption each month.

Some people resort to using quantum and scalar devices aimed to help deflect the supposed effect of radiation to the human body. Interestingly, European countries like France already banned wireless networks in schools and other public areas.
One may never escape the radiation of cell phones and wireless systems while you are out and about as our societies become increasingly wireless, but you can still make your homes a safety haven to have a breather from all these.
