What is the SAR Value in Phones? What Should be the Minimum Value?

The SAR value in phones is a measure that indicates how much radiation emitted by the phone is absorbed by the user's body. SAR stands for Specific Absorption Rate. The SAR value is an important criterion for determining whether a phone is harmful to health.

How is the SAR Value Measured?

The SAR value is measured when the phone is operating at maximum power. The radiation absorption in the areas where the phone comes into contact with the head and body is determined. For this process, a model with the same absorption level as the human head and body and containing fluids similar to those in the human body is used. The grid-like object inside the model measures how much radiation is absorbed. The highest value obtained is recorded as the SAR value.

What Should the SAR Value Be?

The acceptable level of SAR value can vary according to the legal regulations of different countries. However, generally, the SAR value is recommended to be below 1.6 W/kg. This value is determined by the Federal Communications Commission (FCC) of the United States Government. The European Union Council sets this value at 2.0 W/kg. It is important to note that the FCC measures the SAR value as the radiation absorbed by 1 gram of human tissue, while the European Union Council measures it as the radiation level absorbed by 10 grams of human tissue.

Why is the SAR Value Important?

The SAR value is important because high radiation exposure can increase body temperature. It can have serious effects on the head and consequently the brain. Children and young people are at a much higher risk compared to adults because their brains are still in the developmental stage. Additionally, high radiation exposure can increase the risk of cancer. Therefore, paying attention to the SAR value when choosing and using a phone is crucial for health.

How Can We Reduce the SAR Value?

We can take some precautions to reduce the SAR value. These include:

• Place the Phone Away from the Bed Before Sleeping: Instead of keeping the phone on the bedside, placing it away from the bed reduces the duration and level of radiation exposure.
• Choose Phones with Low SAR Values: When buying a new phone, it is important to prefer models with low SAR values.
• Reduce the Time of Carrying and Holding the Phone: Keeping the phone as far away from the body as possible reduces the rate of radiation exposure.
• Use Headphones or Speaker Mode for Calls: Using headphones or speaker mode is safer than holding the phone directly to the ear.
• Keep a Distance of 5-6 Meters Between the Modem and the Phone: Leaving a distance between devices helps reduce the impact of radiation emitted from modems.

Additional Information

• Phones with Low SAR Values: There are many phone models on the market with low SAR values. You can research these models to make a safer choice for your health.
• Extra Precautions for Children: Since children's brains and bodies are more sensitive, it is especially important to limit their phone use and ensure they use headphones if possible.
• Alternative Communication Methods: Using messaging apps over the internet or landlines instead of a phone can also reduce radiation exposure time.

The SAR value in phones measures how much radiation emitted by the phone is absorbed by the user's body. Recommended to be below 1.6 W/kg, the SAR value is a crucial health criterion. By taking various precautions to reduce the SAR value, we can ensure healthier phone usage. Paying attention to the SAR value when choosing and using a phone is essential for protecting our health in the long term.
