We all live in the digital age where our work and routine can be done by one palm-sized device: smartphones.
Although cell phones have several advantages, there is an important risk factor that we must consider – the specific absorption rate (SAR), commonly known as the SAR value.
Expressed in watts per kilogram (W/kg), SAR is the unit of measurement for the amount of radiofrequency energy absorbed by the body. The SAR value is printed in cell phone boxes and as a sticker on cell phones.
So, have you ever thought about how much radiation biological tissue absorbs when using a cell phone? Or do you know how to measure value? You're about to find out!
As a precaution, you can limit you and your loved ones' exposure to RF radiation by using a headset when making calls, choosing a cell phone with a low level of radiation, or calling only when coverage is good (for instance. when you are near a transmitter mast). Beyond that, you can invest in EMF protection products to protect you from the potentially harmful effects of radiation. One of such products that have been shown to be effective is the Phone Computer Wi-Fi Protection.
These powerful Phone Radiation EMF Protectors are designed to eliminate radiation emissions by harmonizing and neutralizing the effects of this harmful energy, rather than shielding or blocking them, these create a healthy life-force chi by constantly generating beneficial healthy Negative Ions. This reduces the heat you feel in your head whilst using your cell phone, mobile phone, cordless phone, iPhone, wireless devices, and Bluetooth.
What Does SAR Stand for?
SAR is a measure of the amount of RF energy deposited in the human head or body each time a cell phone or other wireless device transmits.
This is the maximum SAR value (in watts/kilograms) measured during the SAR compliance test. All cell phone models are tested to ensure they meet international and national exposure limits for RF emissions before they can be sold in any market.
The SAR levels reported for each cell phone model tend to greatly exaggerate actual exposure levels as phone models are tested under laboratory conditions at maximum power to ensure compliance. Cell phones tend not to operate at peak performance during everyday use. To avoid network interference, improve available call time and battery life, cell phones constantly adapt to the minimum power required to make and maintain a call.
There are five categories of SAR value:
A: for a SAR value below 0.4 W/kg
B: for a SAR value of 0.4 W/kg or more but less than 0.8 W/kg
C: for a SAR value of 0.8 W/kg or more but less than 1.2 W/kg
D: For a SAR value of 1.2 W/kg or more but less than 1.6 W/kg
E: for a SAR value of 1.6 W/kg or higher but less than or equal to 2 W/kg
Although the SAR value is determined at the highest certified power level, the actual SAR value of the device during operation can be well less than the maximum value. This is because cell phones are designed to operate at multiple power levels to consume only the power needed to reach the network. Generally, the closer you are to a wireless base station antenna, the lower the power output of the device and vice versa.
How to Measure SAR?
SAR measurements are performed by placing a transmitting cell phone near a model human head. The model is usually filled with a liquid that simulates the electrical properties of the human body. A computer-controlled robot positions a probe to accurately measure the electric fields in the model's head. The cell phone is placed in different positions that are similar to real-life use.
New measurements are taken as SAR values are calculated based on these measurements. All SAR measurements are conducted at the phone's highest output power to provide extreme safety parameters for the end-user and to comply with established limits. The process is repeated over and over again on each frequency band of the phone. Due to this careful investigation, a full SAR test takes up to three weeks.
Importance of Measuring SAR Value
Measuring SAR value is necessary to ensure product safety and compliance requirements are met. Various countries have adopted standards that limit the allowable amount of RF exposure from a variety of wireless devices. Natural and artificial sources of radiation cannot be avoided. SAR testing can measure the amount of radiofrequency exposure from a cell phone or other wireless device. In addition, SAR testing can be performed at all stages of the product development cycle. Early-stage SAR testing makes it easier for the manufacturer to monitor and modify the product.
In some countries, the results of the SAR test must be displayed when the product is offered for sale. In France, for example, this is mandatory. Retailers and manufacturers must demonstrate that the products they offer meet the SAR requirements set by the market or country. SAR measurement standards typically require product manufacturers to consider the harshest and worst operating conditions when testing all frequency bands, so meeting the requirements means the device will never exceed SAR levels. It is worth remembering that this does not indicate normal use of the device.
Who Decides What a Safe Exposure Level Is?
Presently, two (2) international safety organizations have developed exposure guidelines for the general public and workers: the Institute of Electrical and Electronics Engineers (IEEE); and the International Commission on Non-Ionizing Radiation Protection (ICNIRP). ICNIRP guidelines are used in the Middle East, Asia, Europe, and Africa. A similar standard developed by the IEEE International Committee on Electromagnetic Safety (ICES) is used in North and South America. Here is a link for information on the limits that apply to devices in different countries. Both safety guidelines are based on a detailed assessment of the available scientific knowledge.
Safety limits for mobile phones are based on the effects of heating or microwave heating as these are well known and established. However, biological effects (at levels not known to be caused by heating) are not ignored, and international safety agencies consider both thermal and non-thermal effects when setting safety limits. Importantly, the policies have been developed using worst-case scenarios and include additional safety margins to ensure everyone in the community, including pregnant women, children, or the elderly, is protected.
- The SAR limit recommended by the FCC/IC is 1.6 Watts/kg averaged over 1 gram of actual tissue.
- The SAR limit set by the Council of the European Union is 2.0 Watts/kg averaged over 10 grams of actual tissue.
Impacts of SAR on the Human Body
Ongoing SAR research shows that mobile phone RF emissions have both non-thermal and thermal effects on human tissue.
Thermal effects can increase body temperature and affect the brain and head directly. Non-thermal effects can lead to molecular and cellular changes in human tissues.
Children and teenagers may be at higher risk because their brains are still in the developmental stage.
How to Protect Yourself from Cell Phone Radiation?
Constant exposure to EMF radiation has a mainly negative and harmful effect on people.
This can cause, among other things:
- Poor sleep quality
- Decreased vitality
- Headache
- Impaired concentration
- Whisper in ears
- Reduced physical and mental resilience
- Increased pressure in the circulatory system
Use Phone Radiation Protectors
Combat the most common cause of EMF radiation with our Phone Computer Bluetooth WiFi Radiation Protection. These highly protective Phone Radiation EMF Protection now even combats electromagnetic radiation (EMR) which comes off the digital screens of iPhones which are known to cause dizziness, nausea, migraines, headaches, and hair loss.
These powerful Phone Radiation EMF Protectors are designed to eliminate radiation emissions by harmonizing and neutralizing the effects of this harmful energy, rather than shielding or blocking them, these create a healthy life-force chi by constantly generating beneficial healthy Negative Ions. This reduces the heat you feel in your head whilst using your cell phone, mobile phone, cordless phone, iPhone, wireless devices, and Bluetooth.
This product provides you with total phone radiation protection and are suitable for all iPhones, wireless devices, Bluetooth, computers, iPads, and baby monitors and are more effective than any other products which act as a "shield" as they harmonizer and neutralize the harmful effect, rather than attempt to block - which only leads to generating more radiation.
Don’t Hold Cell Phones for Long Periods
It is absolutely not good to use the cell phone for long calls. According to a US government-sanctioned study, cell phone usage is linked to adverse health effects. Therefore, limit mobile phone use to limited, short, and urgent calls only, as the study in the link above shows that this is detrimental to long-term use. If you have to hold your cell phone in your hand for a long time to use the internet, connect your mobile phone to the internet at home and turn on airplane mode. This allows the Internet to work faster and does not use data from your smartphone plan. Beyond that, it also reduces the level of wireless radiation to zero, leaving little electric field radiation due to the phone's battery power.
To reduce this even further, you can use a short selfie stick to hold the cell phone further away instead of holding it in your hand. Never charge the phone while it is in use; please take a break until you have finished charging as the electrical radiation is very high when charging the phone with an electric wall charger. Turn it off when not in use, especially at night (forward it to your home phone if you think you might be having an anxiety attack, but check with your carrier to make sure you are in agreement with the costs).
If Possible, Use Airplane Mode
Don't keep your phone in your pocket, move it away from the body. Perhaps put it in a bag or purse you carry to keep an inch away from your body.
Use Anti-Radiation Air-Tube Headphones
For extra safety, use anti-radiation air-tube headphones. The air tube sends the voice to the ear and prevents EMF radiation from reaching the head through the metal of the cable. Therefore, it is safer to use than other wired headphones.
